@@wcovey25 resistant to heat means less flow after heat up. There are many components of an engine which may require different oil viscosities. However, the manufacturer usually recommends the best suitable viscosity of engine oil. We can go up or down just one W of an oil depending upon climate (heat expansion) and wear and tear (mileage of engine)

Make sure you change your oil. Once the engine is sludged you'll loose oil pressure to your timing chain tensioner and if that gets clogged your chain will get loose, the guides will wear down and maybe skip a tooth /smash a valve
Great videos one of my go too channels . E39m5 restoration . Nathan bmw garage George austers and this guy . Great content for n52 keep up the videos . I have n52b25 so this content is like gold for me and 99 percent of my interest would be oil related . Keep it up bro
I appreciate it. There wasnt so much info on the n52s so I learned alot through trial an error. So I hope these videos can help other e90 owners. These cars are incredible but so finniky😂

The viscosity, discript the first Value, is in these Test the same. The second Value is the Value of Heat resistant. The more is the better for Heat resistant.
My n52b25af was burning 1l per 1000km with bardahl 5w40 but after changing the shaft seal to the gearbox and replacing the oil pan gasket putting Motul 5w40 x-clean I was gettnig 3k km per liter, the next oil change i got the motul 5w40 x-cess and actually right now, Im getting 5000km per liter. No rebuild done, spiritedly driving every drive, I havent changet ccv or valve stem seals. Im at 196k km. I actually think you have some sort of oil leak somewhere.
I own a bmw n52b25a e60 and thus far its 1500 km further after the last oil change with 5w30 and still no oil warning light still waiting for it to pop up….then will poor a litre in and check again how much i got with 5w30. Have to say my oil sump gasket is leaking. Still need to replace it.
That's still pretty good oil consumption for an n52 👌🏼. Try checking your oil pan bolts to see if any are loose and then locktight and tighten them gently again. They can break pretty easily because they are torque to yeild bolts.
@@buildanddrive yes bmw says 1l on 1000 km is acceptable. I think the gasket is the problem though, car has 285.XXX on it. And most of the things I replaced are still oem from 2005. I know the bolts are a pain in the ass had a leaky headgasket when I bought the car 2 months ago. Turned out two bolts were broken. Replaced the two bolts but broke one in the process. But maybe I will check the bolt and replace it I already have a extra set of spare bolts haha just in case.
@@buildanddrive oh really. Think I will check this weekend if some small tightining will work..love your vids btw 💪🏽 and the info u are giving and decent testing stuff. Like the other video the oil stop stuff.
Hi, I really would like too see the cylinder bores. I doubt it is only the piston/ring design that causes this much oil consumption after the rebuild. I did have n52b25 (e60 2005) with 180k km that did about 3000km/l (5w30) No difference with 5w40. This engine did have a supercharger on it with LPG. I replaced the b25 with a b30 that uses no oil between oil changes (8-10k km). Re-ring with valve seals. No hone.
@@pumm5866 do not use a dingleberry hone to make a crosshatch. you need to use an alusil hone. all the info is in the description of this video: th-cam.com/video/1s68Ssb29C0/w-d-xo.html
My 523i with n52b25 engine consumes no noticeable amount of oil between 10.000 km oil changes. I use 0w40 or 5w40 BMW LL 98 or LL 01 oil. The engine is crystal clean inside.
@buildanddrive 2006. The engine has never been opened. But the car has not seen long oil changes. Every 10.000 km gets new oil . I think that the problem of high oil consumption occures when the car has been treated badly in run in period. And due to long oil changes that clogges oil piston rings with dirt. I also own a 2008 116i with n43b16 engine, also with no oil consumption, in which also oil is changed every 10.000 km. I also owned a 330 ci m54b30 engine from 2001, it was sold this summer, and consumed very little amount of oil, maybe 1- 1.5 liter every 10.000 km. The consumption was the same from 100.000 km when I bought it until 310.000 km when sold. Also changed oil every 10.000 km. I use 0w40 or 5w40 acea A3 BMW LL 98 or LL 01 oils in all cars.
Hey. I've got a M54B25 engine, and use 5w40 ravenol and am burning 800-1200ML to 1000km. The car smokes a lot when hot (valve seals and piston rings no doubt) Im thinking about Castrol 5w50, what do you think? During summer, i get 34+ temperatures and in the winter, it goes like -3 most of the time at maximum, othervise little above 0 (all temps in celsius) Do you think the 5w50 is a good idea? I run the car quite passionately, so it burrnssss
Winter run a 5w30 and summer run a 5w40. You mind as well try and protect the engine rather than choking it with a thicker oil... I didn't see much improvement on my oil consumption. The thicker oil actually reduced it a bit but not enough to warrant using it all the time.
I have been unlucky enough to have bought one of the many BMW oil burners. The compression, pcv and valve seals are ok, but still it burns a lot of oil. I think it could be bad/damaged oil rings, or could it be something else?
Check for vacuum leaks (in my other smoke test video). This would help the CCV to work correctly. Otherwise it's just the bad piston design and worn out rings unfortunately.
Hey bro, another great upload. Thanks for all the time and effort you put in to your videos and all the information you give to your subscribers. The fuel prices where I am are very low but I gave you a big thumbs up anyway. Stay cool bro and keep your videos coming. Very interesting watching. ✌
Thanks vincent, your comment is very motivating. I have so many ideas for videos and they are challenging to make. Where do you live and how much is fuel prices there?
Hey bro, you deserve the boost. I live in Russia and the price per litre is 70 euro cents. Diesel is a little more expensive 73 euro cents. I thought you might have seen where I'm from by your stats, but maybe I'm wrong. I tore apart my Bmw e93 328i N52 B30 engine originally imported in from the states. In Europe they're refered to as the 330i as you well know. Been a bit stuck with my rebuild parts due to the sanctions, but I've worked around the problem now and will start putting mine back together. I didn't have any problems with my engine, it was purely a complete refresh. I stripped the bottom half also. Stay cool man ✌
Try 5w30 ect c3 shell dexos2 oil after couple of thousand km the engine oil control rings will be clean and sealing again, my oil consumption is dropped significantly. On my M54B22 engine
it all depends on the head... lifters? thin oil is great.... but anyways in my peugeot 1.4 8v gasoline, I had insane oil consumption... kinda normal for the engine and high miles it has 200.000kms... so I do 20w50 2/3 and 1/3 of 80gear oil. cause in this particular engine it basically does not have tinny passages. anyways... oil consumption went from 1L every 750 to 1L every 2000 ... I have bad valve stem seals too though... After I fix them I will probably go back to thinner 15w40. Save on gas lol havent really changed from 100% 20w50 to 2/3-50 and 1/3-80 edit*** I live in Brazil... I dont recommend the whole mineral super thicker oil in colder weather areas. 0~5w is the way to go incolder areas.. weather you use 20/30/40 or 50 will come down to temp and type of engine... sometimes the oil consumption does not added up to the fuel consumption you will have. just saying...
It depends what is the source of your oil being burned. If it's oil separator, then viscosity won't make it any better. In my Porsche 16.6 cSt oil is being burned like crazy, 18.5 cSt has 0 consumption.
Yes, if it's the CCV, nothing you can do. On an n52 is the piston design that causes burning. A thicker oil helps only a little bit which causing increased fuel consumption.
Don't know how i got here? anyway I enjoyed the video.. great job 👍.. you obviously got some skills to breakdown the motor..Im not sure why you didn't increase the oil return holes in the pistons and go with some better oil control rings? so much labor for poor results is disheartening..
Don't know if there are any better oil control rings, unlike the m52tu, those were a better design but didn't come to the n52 as far as I know. I didn't know about the oil return holes would help that much more with the oil consumption. I assumed new rings would get me at least 1L/3000kms but it didn't. Only about 1L/1600. So bmw designed it that way from the start which I think is crazy
I did hone the block BUT you don't need too if everything measures straight. And if you do, it's an alusil block so you need to use a special tool with abrasive pads + a compound... NOT A DINGLEBERRY HONE.
Hi, great video! I wonder what causes this high oil consumption that you have? This is the first video that I've seen from your channel and I also wonder why did you decided to rebuild the engine with new piston rings and so on? In a 125i with N52B30 (N or K, the one with the plastic valve cover) I need to top up 1.5 litres in between oil changes (10000 kms). The tendency is to lose 250ml every 1500 kilometers roughly. I have changed the oil sump gasket with new one and new bolts for it, the front crankshaft seal (where the crank pulley is located), pcv pipes (new design), VANOS solenoids and lastly a cheap valve cover with new gaskets. The valve cover cracked half a year ago next to the pcv diaphragm so I am in need of a new one and even though it is leaking oil from there, it's not that much and still within 250ml in 1500 kms. Keep up the great videos!
I have an n53b30a 330i and burns 1L/1000 - 1250 miles so around 1600/2000 km I use 5w-30 mannol now as it's only £22 for 5 litres have not tried a thicker oil thougg
I have the exact same engine in US with 260k miles and it doesn’t really burn any oil. May be 1 quart or liter per 4k miles. I think high revs on autobahn doesn’t help.
I have a 2006 330i. I think it is b30. Absolutely love this car with auto ZF trans. Car has been maintained very well with 7k miles oil change with Mobil one 5w30.
My 2008 Camry HYBRID recommended 0-20 weight oi, l guess thinner oil for less resistance when the crank rotates thru the oil for better gas mileage, it never burned any oil at all, guess i got a good one, it was made in Japan. Best car I ever owned, 38-40 MPG on the hwy, not 1 thing happened to it in 8 years, just change the oil. Toyota makes awesome vehicles, so I sold it and got a 2016 Lexus NX 200T, We have owned it 7 years and I just had the servicing done and they couldn't find anything wrong with it. We also have a 2012 Sienna, also a great van, had to replace the water pump at 60k miles though.
A thicker oil WILL cause worse fuel economy. Theres more drag on the engine. Try swimming in honey vs water and see how much more energy you spend to get to the finish line. Theres a reason manufacturers have moved on to thinner and thinner engine oils over the years..........
@@buildanddrive yes exactly. It is based on engine temperatures. Hotter engines that use 40 weight oils will have approx the same viscosity as cooler engines that use 30 weight oils at their operating temps. The oil film needs to stay in a fairly strict range of viscosity to do an optimal job. So the weight of oil recommended is based on the engines operating temperature. Too thick or too thin will push it out of its optimal viscosity.
Hey man I subscribed. It's weird how with my 09 n52b25 once a .25 of a litre drop in the oil reading...oil usage speeds up to .25l per 800km. All up I get around 5k to 6k km per litre of oil on 5w40.
@@buildanddrive ok cheers. Mine is an Feb 09 build and I thought I still had the old rings. I recently pulled plugs and the threads had oily residue so might be valve leak internally.
In the handbook of my car, it says to use a 5W-40 Oil ONLY... My 1998 Toyota Celica has covered 236,000 Miles and is fitted with a 1.8 Litre 7A-FE 4 Cylinder DOHC engine ..OK it only produces a paltry 113 BHP ..However, the speed limit on our Motorways here in the UK (Freeways for American viewers) is 112 KM/H ( 70 MPH) and my car does this with comparable ease. My car is burning a litre of oil every 1,000 Kilometers.. Here in the UK a litre of oil costs around £5.60 GBP (5 Litres cost me £28) I drive around 1500 KM a Month ..So let's look at the cost for me. Option one ..... Top up the oil using 5W-40 as and when required 1.5 Litres per month...Total cost £5.60 x 1.5 = £8.40 GBP of oil a month Option two..... Swop the oil and use a 5W-50 oil and RISK the engine blowing up..... Total cost Around £3,000 GBP for an engine rebuild. I WILL SELECT OPTION ONE..... It is a "No brainer" 😁 But thank you for this video anyway.
Oil pessure dont mean much its oil flow that really matters. Outside temp is only relitive at startup. After warm up it dont matter one bit. Please educate yourself.

If you treat your car like a tractor for tenths of thoudands of kilometers/miles, it will burn oil. WOT @ 7K rpms is fine for a few times, not all the time.
Yes. 10w40 is a better oil depending on the brand and the oil lab test. If you follow the oil forums they have a bunch of good oils that are much better than 5w40 and protect better. I am in a cold climate and prefer to change my oil once per year so 5w40 it is for me

@@awaisiqbal8934 I've heard alot of engine builders talk about how 5w50 is superior to 5w30 for performance cars, it's just expensive and hard to make, only a few companies carry 5w50. They both have the same cold flow but when hot the 5w50 resists heat better. I run it and it's good
@@wcovey25 resistant to heat means less flow after heat up. There are many components of an engine which may require different oil viscosities. However, the manufacturer usually recommends the best suitable viscosity of engine oil. We can go up or down just one W of an oil depending upon climate (heat expansion) and wear and tear (mileage of engine)
@@awaisiqbal8934 that’s not true lol

Any advice on how to prevent the potential timing chain failures on the BMW E90 models?
Make sure you change your oil. Once the engine is sludged you'll loose oil pressure to your timing chain tensioner and if that gets clogged your chain will get loose, the guides will wear down and maybe skip a tooth /smash a valve
@@buildanddrive Thanks so change oil and fiilter with high quality oil every 5000 km?
Great videos one of my go too channels . E39m5 restoration . Nathan bmw garage George austers and this guy . Great content for n52 keep up the videos . I have n52b25 so this content is like gold for me and 99 percent of my interest would be oil related . Keep it up bro
I appreciate it. There wasnt so much info on the n52s so I learned alot through trial an error. So I hope these videos can help other e90 owners. These cars are incredible but so finniky😂
@@buildanddrive 100 percent . I’m sitting on 107 k miles . When I first got the car I was using oil from dealership 5-30 ll04 it would do 1500 miles for liter . Now I’m using Castrol edge 5-30 ll01 I’m getting 2k miles .
i have 2.0tdi and my engine used 1.5l 5w30 oil in 4000km and i changed piston rings too
Well done 👏🏽. That's not too bad oil consumption

The viscosity, discript the first Value, is in these Test the same. The second Value is the Value of Heat resistant. The more is the better for Heat resistant.
2009 bmw 128i manual 6 speed, running 5w30 liqui molly 1.5 l per 5000miles including 2 full summer track days in Amp Dawsonville Georgia USA.
Thats pretty good oil consumption, even for track use 👌🏼
I think the issue with this engine , as i saw one guy recently speaking about..are the piston oil rings. There are 2 models, one bad ,one good.
Can you find the video again? The m54 engine had the "tu" version which had a different style of piston oil ring that didn't burn oil
My n52b25af was burning 1l per 1000km with bardahl 5w40 but after changing the shaft seal to the gearbox and replacing the oil pan gasket putting Motul 5w40 x-clean I was gettnig 3k km per liter, the next oil change i got the motul 5w40 x-cess and actually right now, Im getting 5000km per liter. No rebuild done, spiritedly driving every drive, I havent changet ccv or valve stem seals. Im at 196k km. I actually think you have some sort of oil leak somewhere.
Interesting. Thanks for sharing. I'll take another look to see if something is leaking again 😂
I own a bmw n52b25a e60 and thus far its 1500 km further after the last oil change with 5w30 and still no oil warning light still waiting for it to pop up….then will poor a litre in and check again how much i got with 5w30. Have to say my oil sump gasket is leaking. Still need to replace it.
That's still pretty good oil consumption for an n52 👌🏼. Try checking your oil pan bolts to see if any are loose and then locktight and tighten them gently again. They can break pretty easily because they are torque to yeild bolts.
@@buildanddrive yes bmw says 1l on 1000 km is acceptable. I think the gasket is the problem though, car has 285.XXX on it. And most of the things I replaced are still oem from 2005. I know the bolts are a pain in the ass had a leaky headgasket when I bought the car 2 months ago. Turned out two bolts were broken. Replaced the two bolts but broke one in the process. But maybe I will check the bolt and replace it I already have a extra set of spare bolts haha just in case.
Mine oil pan bolts rattled loose. I did the gasket again anyway
@@buildanddrive oh really. Think I will check this weekend if some small tightining will work..love your vids btw 💪🏽 and the info u are giving and decent testing stuff. Like the other video the oil stop stuff.
I have been using 0w-40 to BMW LL-04 for some years in BMW M47R diesels for some years with no issues
What was your oil consumption?
@@buildanddriveZero oil consumption between 6,000 mile changes
Hi, I really would like too see the cylinder bores. I doubt it is only the piston/ring design that causes this much oil consumption after the rebuild. I did have n52b25 (e60 2005) with 180k km that did about 3000km/l (5w30) No difference with 5w40. This engine did have a supercharger on it with LPG. I replaced the b25 with a b30 that uses no oil between oil changes (8-10k km). Re-ring with valve seals. No hone.
You can kinda see the bores here: th-cam.com/video/FHOHIt18Rb8/w-d-xo.html
@@buildanddrivewell i am about to rebuild a n53b30 with the same crosshatch hone. I do not like it because of the alusil.
@@pumm5866 do not use a dingleberry hone to make a crosshatch. you need to use an alusil hone. all the info is in the description of this video: th-cam.com/video/1s68Ssb29C0/w-d-xo.html
@@buildanddrive Machineshop already did it. Said it would be OK...
My 523i with n52b25 engine consumes no noticeable amount of oil between 10.000 km oil changes. I use 0w40 or 5w40 BMW LL 98 or LL 01 oil. The engine is crystal clean inside.
What year is your car made?
@buildanddrive 2006. The engine has never been opened. But the car has not seen long oil changes. Every 10.000 km gets new oil . I think that the problem of high oil consumption occures when the car has been treated badly in run in period. And due to long oil changes that clogges oil piston rings with dirt. I also own a 2008 116i with n43b16 engine, also with no oil consumption, in which also oil is changed every 10.000 km. I also owned a 330 ci m54b30 engine from 2001, it was sold this summer, and consumed very little amount of oil, maybe 1- 1.5 liter every 10.000 km. The consumption was the same from 100.000 km when I bought it until 310.000 km when sold. Also changed oil every 10.000 km. I use 0w40 or 5w40 acea A3 BMW LL 98 or LL 01 oils in all cars.
Hey. I've got a M54B25 engine, and use 5w40 ravenol and am burning 800-1200ML to 1000km. The car smokes a lot when hot (valve seals and piston rings no doubt)
Im thinking about Castrol 5w50, what do you think? During summer, i get 34+ temperatures and in the winter, it goes like -3 most of the time at maximum, othervise little above 0 (all temps in celsius)
Do you think the 5w50 is a good idea? I run the car quite passionately, so it burrnssss
Winter run a 5w30 and summer run a 5w40. You mind as well try and protect the engine rather than choking it with a thicker oil... I didn't see much improvement on my oil consumption. The thicker oil actually reduced it a bit but not enough to warrant using it all the time.
I have been unlucky enough to have bought one of the many BMW oil burners. The compression, pcv and valve seals are ok, but still it burns a lot of oil. I think it could be bad/damaged oil rings, or could it be something else?
Check for vacuum leaks (in my other smoke test video). This would help the CCV to work correctly. Otherwise it's just the bad piston design and worn out rings unfortunately.
Hey bro, another great upload. Thanks for all the time and effort you put in to your videos and all the information you give to your subscribers. The fuel prices where I am are very low but I gave you a big thumbs up anyway. Stay cool bro and keep your videos coming. Very interesting watching. ✌
Thanks vincent, your comment is very motivating. I have so many ideas for videos and they are challenging to make. Where do you live and how much is fuel prices there?
Hey bro, you deserve the boost. I live in Russia and the price per litre is 70 euro cents. Diesel is a little more expensive 73 euro cents. I thought you might have seen where I'm from by your stats, but maybe I'm wrong. I tore apart my Bmw e93 328i N52 B30 engine originally imported in from the states. In Europe they're refered to as the 330i as you well know. Been a bit stuck with my rebuild parts due to the sanctions, but I've worked around the problem now and will start putting mine back together. I didn't have any problems with my engine, it was purely a complete refresh. I stripped the bottom half also. Stay cool man ✌
Try 5w30 ect c3 shell dexos2 oil after couple of thousand km the engine oil control rings will be clean and sealing again, my oil consumption is dropped significantly. On my M54B22 engine
What was the oil consumption before and after?
@@buildanddrive before like 800 km per liter and after 2000 km/l and later it became like 3500 to 4000 km per liter oil, so im very happy
First I also used this 5w30 and the liquimoly Ceratec. But I don't know if that helped or not.....
it all depends on the head... lifters? thin oil is great.... but anyways in my peugeot 1.4 8v gasoline, I had insane oil consumption... kinda normal for the engine and high miles it has 200.000kms... so I do 20w50 2/3 and 1/3 of 80gear oil. cause in this particular engine it basically does not have tinny passages. anyways... oil consumption went from 1L every 750 to 1L every 2000 ... I have bad valve stem seals too though... After I fix them I will probably go back to thinner 15w40. Save on gas lol havent really changed from 100% 20w50 to 2/3-50 and 1/3-80
edit*** I live in Brazil... I dont recommend the whole mineral super thicker oil in colder weather areas. 0~5w is the way to go incolder areas.. weather you use 20/30/40 or 50 will come down to temp and type of engine... sometimes the oil consumption does not added up to the fuel consumption you will have. just saying...
5W40 1.9tdi asv 278k km i change oil every 10k km and any i don't suspect any oli missing its same amounth like when i pour it in engine.
Try and measure it when it comes out next time. I would be interested. 10k without adding oil at that mileage is excellent 👍🏽
N57 6k changes, now on 190k no issues
I agree 💯.
It depends what is the source of your oil being burned. If it's oil separator, then viscosity won't make it any better. In my Porsche 16.6 cSt oil is being burned like crazy, 18.5 cSt has 0 consumption.
Yes, if it's the CCV, nothing you can do. On an n52 is the piston design that causes burning. A thicker oil helps only a little bit which causing increased fuel consumption.
Don't know how i got here? anyway I enjoyed the video.. great job 👍.. you obviously got some skills to breakdown the motor..Im not sure why you didn't increase the oil return holes in the pistons and go with some better oil control rings? so much labor for poor results is disheartening..
Don't know if there are any better oil control rings, unlike the m52tu, those were a better design but didn't come to the n52 as far as I know. I didn't know about the oil return holes would help that much more with the oil consumption. I assumed new rings would get me at least 1L/3000kms but it didn't. Only about 1L/1600. So bmw designed it that way from the start which I think is crazy
When you changed the rings, did you hone the cylinders?
I did hone the block BUT you don't need too if everything measures straight. And if you do, it's an alusil block so you need to use a special tool with abrasive pads + a compound... NOT A DINGLEBERRY HONE.
Hi, great video! I wonder what causes this high oil consumption that you have? This is the first video that I've seen from your channel and I also wonder why did you decided to rebuild the engine with new piston rings and so on?
In a 125i with N52B30 (N or K, the one with the plastic valve cover) I need to top up 1.5 litres in between oil changes (10000 kms). The tendency is to lose 250ml every 1500 kilometers roughly. I have changed the oil sump gasket with new one and new bolts for it, the front crankshaft seal (where the crank pulley is located), pcv pipes (new design), VANOS solenoids and lastly a cheap valve cover with new gaskets. The valve cover cracked half a year ago next to the pcv diaphragm so I am in need of a new one and even though it is leaking oil from there, it's not that much and still within 250ml in 1500 kms.
Keep up the great videos!
The high oil consumption is caused by the faulty piston ring design. BMW changed this after 2008 in other n52 engines
Hi brother for diesel should I use 5w30 or 5w40in country like Thailand.Cambodia the weather not cool
Yes any 5w30 LL04 bmw certified oil is fine for a diesel.
With 5-50 oil u can get trouble with clearances in crankshaft bearings. Not lubricating properly.
yeah its a stupid idea to use anything else than what the owners manual says
Why. 5W is thin
I have an n53b30a 330i and burns 1L/1000 - 1250 miles so around 1600/2000 km
I use 5w-30 mannol now as it's only £22 for 5 litres have not tried a thicker oil thougg
Try a 5w40 and let me know if it changes anything
I have the exact same engine in US with 260k miles and it doesn’t really burn any oil. May be 1 quart or liter per 4k miles. I think high revs on autobahn doesn’t help.
Do you have the n52b25 or n52b30?
I have a 2006 330i. I think it is b30. Absolutely love this car with auto ZF trans. Car has been maintained very well with 7k miles oil change with Mobil one 5w30.
Royal purple xpr 10w60
Buy me some and I'll test it
My 2008 Camry HYBRID recommended 0-20 weight oi, l guess thinner oil for less resistance when the crank rotates thru the oil for better
gas mileage, it never burned any oil at all, guess i got a good one, it was made in Japan. Best car I ever owned, 38-40 MPG on the hwy,
not 1 thing happened to it in 8 years, just change the oil. Toyota makes awesome vehicles, so I sold it and got a 2016 Lexus NX 200T,
We have owned it 7 years and I just had the servicing done and they couldn't find anything wrong with it. We also have a 2012 Sienna, also
a great van, had to replace the water pump at 60k miles though.
Yes I am also a Toyota guy before getting my BMW. My parents car has gone 240,000kms with only basic maintenance. It's amazing!
How do you rest the oil levels without I drive of it does work on a 5series N52
You have to warm up the car and use the button on the left turn signal to toggle the oil level
A thicker oil WILL cause worse fuel economy. Theres more drag on the engine. Try swimming in honey vs water and see how much more energy you spend to get to the finish line. Theres a reason manufacturers have moved on to thinner and thinner engine oils over the years..........
Definitely. The thicker oil is only really useful on the track at very high temps.
@@buildanddrive yes exactly. It is based on engine temperatures. Hotter engines that use 40 weight oils will have approx the same viscosity as cooler engines that use 30 weight oils at their operating temps. The oil film needs to stay in a fairly strict range of viscosity to do an optimal job. So the weight of oil recommended is based on the engines operating temperature. Too thick or too thin will push it out of its optimal viscosity.
Exactly 👍🏼

Hey man I subscribed.
It's weird how with my 09 n52b25 once a .25 of a litre drop in the oil reading...oil usage speeds up to .25l per 800km. All up I get around 5k to 6k km per litre of oil on 5w40.
Thanks for subbing! 🙏🏼The oil sensor isn't very precise. Your oil consumption seems perfect 👍🏼
@Leif Harald longbeard III when was it? And no the comment is not useless
Yeah I believe after 2008, they changed the piston design and updated the cylinder head for better oil flow to avoid the ticking
@@buildanddrive ok cheers. Mine is an Feb 09 build and I thought I still had the old rings. I recently pulled plugs and the threads had oily residue so might be valve leak internally.
I wonder if there is a hairline crack in the cylinder head that would cause that.

Tell me about it😂😅
In the handbook of my car, it says to use a 5W-40 Oil ONLY... My 1998 Toyota Celica has covered 236,000 Miles and is fitted with a 1.8 Litre 7A-FE 4 Cylinder DOHC engine ..OK it only produces a paltry 113 BHP ..However, the speed limit on our Motorways here in the UK (Freeways for American viewers) is 112 KM/H ( 70 MPH) and my car does this with comparable ease.
My car is burning a litre of oil every 1,000 Kilometers.. Here in the UK a litre of oil costs around £5.60 GBP (5 Litres cost me £28)
I drive around 1500 KM a Month ..So let's look at the cost for me.
Option one ..... Top up the oil using 5W-40 as and when required 1.5 Litres per month...Total cost £5.60 x 1.5 = £8.40 GBP of oil a month
Option two..... Swop the oil and use a 5W-50 oil and RISK the engine blowing up..... Total cost Around £3,000 GBP for an engine rebuild.
I WILL SELECT OPTION ONE..... It is a "No brainer" 😁
But thank you for this video anyway.
Yes, option 4. Buy an electric car 🚗😂
BMW's a company that seems to worse as time goes on.
Like Ford

Bro seriously😂 5w is the viscosity 5w-30 or -40 refer to heat resistance you want to increase viscosity use 10w someting
Yes. 10w40 is a better oil depending on the brand and the oil lab test. If you follow the oil forums they have a bunch of good oils that are much better than 5w40 and protect better. I am in a cold climate and prefer to change my oil once per year so 5w40 it is for me
I understand but curious what is the thicker oil 10w40 or 5w50😅
Use a lower w rating if you want it reliable in winter snow.
