Excellent, excellent video. You touched on every conceivable reason why a turbo may fail including manufacturing defects. This video is very impressive. Well done.
Thank you very much. I appreciate that.
@ECPP i just wanted to add that another issue with these turbos is the use of non-approved brand of oils for the lubrication. For Mercedes, their brand of oil works excellently. So, i discovered that if you use the right oil code, in this case, Mercedes 229.5 oil, you will have less problems with the engine. These newer engines are now more tightly linked to a specific oil than engines in the past. All the excellent reasons in your video is why their oil works better than using any other oil.
I have a 2016 subaru forester xt, 2.0 turbo, about 250hp, 30mpg and just turned 286,000 miles, no problems, runs like the day I bought it. I change oil every 4000 miles which is key to survival. Also a northern Minnesota car, so it sees extremes from -30 in winter to 95 in summer.
Subarus are tough cars and there's a lot of them in my area. The best all wheel drive of any vehicle.
That is great to hear and shows how maintenance can make a difference.
Thanks
Finally, a clear explanation detailing how a turbocharged engine works, and how to take care of them. Love your videos! Keep up the great work!
Thank you so much. I appreciate the support. Have a great weekend.
Engineering Explained goes in-depth on this subject.
It wasn't explained much at all, it did however, tell many many people they should be changing their oil, and more often on turbos.
So that makes the video a clear winner.
It's amazing that being overcharged for a new vehicle is a good thing if it causes you not to buy the vehicle.
you said it man.
Indeed, over and out
Aahhh
But if you don't buy it, you weren't overcharged.
Lol
The chicken and egg conundrum.
Proud new car owner: "Take a look at my incredibly special high-performance car!"
Friend: "Cool! Turbo-charged?"
Car owner: "Nope, even better! OVER-Charged."
I have a 2.0 turbocharger engine in my Cadillac CT5. I change the oil and filter every 5K, i use full synthetic oil, and i don't beat on my car.
I set my cruise to either 60 or 75 mph, depending on traffic, and i stay in the slow lane.
I mix the oils. 0W-20, is what it calls for, and 5W-30 to deal with the heat. Seems to work just fine.
I rarely, if ever, full throttle my car. There's no need to. I give myself plenty of time to get anywhere, and i make my hands free calls as i calmly go my way.
Ive learned by experience, to go back to simplicity. I now have a manual transmission, non turbo, port injected car. I dont need a rocket for a car.
Which means that if you're in the USA you have a used car, a sports car or a Jeep. MOST of the turbos out there today are being used for milking more power out of a given displacement, meaning they can use a smaller engine, all in pursuit of fuel economy.
@@johnsanford3596im from Norway, have an Opel.
Right, you're very right, more components = more complications = additional failure points! When I bought my new-to-me 2017 Lexus LS it was one of my primary considerations. Before I even started shopping for it I went to the Lexus forums, mainly to find the possible failure points if any.
I learned this car offered air suspension for a while, which would surely not be a bad thing to have, even though after a few models years Lexus just deleted the feature. Because the air suspension was a huge failure point (as almost all pneumatic systems generally are). Also found out they sold the LS in AWD (all wheel drive) models, and RWD models. While there were no particular issue with AWD hardware, again I decided not to buy any car that had it (more components = needless complexity = another possible failure point).
The only good failure points, are the ones you figured out how to avoid, in the first place.
I also have simple vehicles. Newest is a 2003. No turbos. All of them have far north of 100k miles. Keep the fluids and other lubes fresh and they just keep going
Auto makers taking existing 4cyl engines and slapping in turbos, they were not made for that kind of stress. You need heavily fortified cylinders, heads, rings, and pistons.
Basic 4cyl normally aspirated or fuel injection can't take the extreme pressures.
Totally agree with you on that. Usually turbo engines have been beefed up to tolerate the boost
Right, you need 4 bolt main bearings, and several more cylinder head bolts designed into that engine block, for starters. Which the automakers don't bother doing most of the time.
I've said this too! A normally aspirated engine that has a turbo slapped on it will not last as long! Everything is a trade off! If you do not beef up the original engine, it will wear out faster. This is why diesel engines are very robust; they run higher compressions and need more strength to survive as expected.
When car manufacturers suggest 7500 or 10000 mile oil changes, that is specifically designed to make the engine fail shortly after the warranty is up, os you have to buy a new car. Because the cost of an engine is so high that it's not worth it.
In 2001 I drove to a far away city to pass my driving test and I took some lessons to get familar with the roads.
The lady who owned the car for the driving school was very happy to have scored a car that needed 8000km (5000 mile) oil changes. I felt that was way too high back then
@@rohitnijhawan5281 I guess it depends. Exclusively highway miles you might be able to get away with 7500 miles. For cars with mostly city driving I'd say 3000.
Had a Garrett turbo in my FIat 124 Spider (2017). Worked for a company (retired last year) that remanufactured turbos. In my modest opinion, as you have stated, turbo 4s have great torque, but they require more oil change maintenance. In general, the turbo can last 150k miles with proper maintenance. But do people know how to handle turbos. I found out one hot day when I lived in SoCal where I shut the engine off after a hard day's return from the beach. I will not purchase a vehicle going forward with a turbo. I have a V6 normally aspirated engine now, still changing my oil at 5k miles, a habit that I had learned having a turbo. Thanks for explaining turbos, for your presentation was quite accurate and recommended for people who own turbo vehicles.
Your statement about working for a company that remanufactured turbo chargers, but you would not buy a vehicle with one tells me all that I already knew about turbocharged engines. If you own a diesel, you need a turbo, if you own a gasoline engine, no. Only diesel engines are built to handle the additional stress induced by a turbocharger.
@JamesAgans very good assumption. I meant gasoline engines. Turbos are great for short to medium term mileage, but they tend to blow eventually so taking care of them with frequent oil changes is very important.
You've got me curious re: "I found out one hot day when I lived in SoCal where I shut the engine off after a hard day's return from the beach." What happened, did you not let the engine idle before shut off, causing the turbo get toasted or something ?
@robertmaybeth3434 the smell of heavy gasoline was evident. The car started up the next day, but I realized that I did overtake the engine. Never again, and I traded the turbo engine/car in at 70k and it was in top condition. I religiously changed my oil 4 to 5k miles.
I’ve wondered why diesel engines that are turbos last a long time but gasoline engines do not seem to. Well until strict emissions clogged up diesel.
Diesel is a lubricant while petrol is a solvent…and yes the egr is the diesel engine killer.
Because they run continously.
@@blurglide BMW M57 turbo diesel engine runs for 300k+ miles without issues. Normal car driving. 3 series.
Alot of diesels have very heavy built well built internals, iron blocks, low rpm, and diesel is alot better lubricating than gasoline.
It has nothing to do with the fuel being a lubricant, its because if they half assed a diesel design with weak rods, crank, and pistons it would explode in a week. They have to be tough just to run because of the nature of compression ignition
I myself hate that the OEM's are putting tiny lawnmower engines in car's and trucks. It's almost impossible to get away from turbos and VVT and GDI. But if you do have a vehicle with a turbos maintenance is key. If your car or truck says to do oil changes at 5000 miles, do it at 3000 or 3500. And definitely stay away from quick lube places. But a high quality oil and filter and do it yourself or have your mechanic change it with your own oil and filter. Keep clean air filters in your car. And keep up on coolant maintenance. This will greatly improve the lifespan of your turbo charger.
What brands of oil are low quantity?
Don't immediately turn off your engine after a long highway run. If you turn it off, the hot turbo bakes the oil at the turbo. Then you circulate the baked oil. Let it run for a minute or two to cool that turbo off.
@@georgesontag2192 - I wish they'd put a time delay on shut down if the engine is at or above a preprogrammed temperature. That way, we can shut it down, get out, lock the doors and walk away.
Agreed.
I’m not paying v8 prices for mouse 🐁 motors and half assed turbos--which is why the Tahoe is far more popular that the Ford alternatives.
My first turbo (of many) was a 1984 Merkur xr4ti. My mechanic said there's 2 rules you must follow with turbos:
1. After aggressive driving (high turbo usage) always allow for 2 to 3 minutes of idling before switching off engine.
2. Change the oil every 3 months/3,000 miles with original manufacture's oil filter and recommended oil.
He was right
Yes, very oil-finicky is a turbo-charger, the tolerances inside are tiny. Mitsubishi sold turbo cars for a while when they were still around, but they were one of the (very few) engine makers that bothered to do it right. Mitsu engineers designed in a separate small filter just for the oil going into the turbo! Even more amazing, the clever designers added a small separate oil reservoir in the oil supply hose, just to feed the turbo bearing (in case the owner forgot to do your rule number 1)!
Thanks, you answered my question about oil changes without even asking ;)
How long did your vehicle last? How many miles on the odometer?
@abhijeetaanand2334 It was trashed in a crash at 130+k miles. It was the 2nd most trouble free car we ever owned. The #1 trouble free car l owned was a 1972 AMX Javelin 401 C.I.D. stick. (170+k).
I agree, 2500 to 3000 mile oil changes for turbo engines. Forget about 5000 mile oil changes.
People need to learn that oil changes and maintaining their vehicles is much cheaper than a new turbo or engines. Another great informative video Mark. People should listen to your videos and they would save money 💰
Oil changes & maintenance is more easier in a new car!
No turbo ever. Normally aspirated V-6 is the way!
Inline 6 is more reliable than any v6.
I agree but the choice is going away
Camry hybrid drive train.
Electric car goodness without the electric car drawbacks. 😊
Anyone here had any negative experience with the Honda 2.0 Turbo?
@@Getyourdoe. GDI without port injection can be a concern.
My cars are older with port injection only.
New Toyota hybrids have both systems.
I only know 1.5 turbo has problems.
So costlier gas, shorter engine life. Costlier cars and maintenance…No thanks I want naturally aspirated !
Even though I’ve told her not to my daughter, bought a 1.5 Honda accord 2019 turbo, she has 110,000 miles so far… So far so good. I think she escaped the blown head gasket/oil dilution issues.
There is NO escaping the head gasket issue. Her driving, maintenance habit, and fuel selection have prolonged the inevitable.
@ 🙏🏾 maybe 🤣 just like my 2016 versa CVT, 210,000 miles with no issues… Yet, unless you count one bad coila issue
@@Beethechange1 210k on an original Jatco CVT!!! Looks like your household does indeed defy the laws of physics! I wish the best to you and yours. 🤞
@ 🤣🤣true that.. hoping for 250k🙏🏾 2 more years
Then tell her not to drive for short trips without warning up the engine for 3-4 minutes and use thicker oil in oiler weather that's the problem
Told my daughters to change the oil every 5000, and they have just waited until the light told him to… Kids do not listen
I never rely on the oil change light.
Just mileage.
@ true that.. But i bet 95% of car owners do..
@@Beethechange1 right here bud🙋. I always follow that rule. And I do the oil change myself.
@ another reason to do it yourself, especially the quick change places they always strip bolts every car I’ve ever had in the past has been damaged by them, but you did not find out until the next oil change🤣
@@Beethechange1 I hear that! Took it once never again!
Terrific amount of new info on turbos. (at least new to me) Love hearing this level of detail on engine design and operation.
A lesson is to not buy a used turbo charged car. You have no idea how well the previous owner maintained and fueled them.
I really enjoyed this. Thank you
You are very welcome.
Great video. When I talked to the service manager at the Honda dealership he said to change the oil on the Honda 1.5 liter turbo no later than every 5000 miles (1500 miles less that the manufacturer's recommendation)
Glad I saw this video, learned something here, very helpful, thanks. I’ll stay with non-turbo motors.
You're welcome.
Yip, had two Ford Taurus SHO's. 2010 and 2013 and both maintained meticulously and still had issues such as leaking turbos, poor build quality. Turbo went 120k kms . Never buying a newer Ford again. People don't know how to maintain turbos, such as not turning your vehicle off as soon as you stop, let the car run for 30 seconds at least before turning off the car.
Yes you are right, many people simply do not operate them accordingly. They do require slightly different maintenance and operation.
Turn off the stupid auto/start stop, as abrupt shutting off the engine isn't good for that and the turbo.
@ exactly that’s a botched technology
I have a '16 Expedition with the 3.5 TT with over 231k miles, no issues. Also, a '17 WRX with 193k miles, also, no issues. Before that, an '06 Mazdaspeed 6, 178k miles, no issues. Good oil and paying attention to your levels and changes makes a difference, it would seem.
I have a 2005 Volvo S80 2.5T it has over 300K miles on it still runs great. The right cars with a turbo well taken care of and serviced regularly they can last a long time. You can’t treat it like a naturally aspirated vehicle they do need more service. The performance makes the difference. You cannot run cheap gas they run best on a premium fuel. It also helps mileage.
Good video. Very good basic explanation of a lot of things we read about but rarely see unless we are mechanics. I have had two of these "modern" 2.0Ts and my verdict on them is mixed. They perform great, smoother than I thought they'd be, and get fantastic mpgs. However, they do require more repairs as having more parts to fail means more will fail. For example I had one plastic turbo coolant line plug fail and it was $300 repair for a $2 plastic part. I also had wastegate actuator wear out at 70K miles. IMHO, these costs wipe out the fuel economy savings so I have begun to switch back to NA engines only. Just replaced one 2.0T at 90K miles with a 3.5 NA V6. Gonna just stick with that until they force me out with EVs.
Good video with a lot of good info for the uninformed. The extra plumbing to get oil and coolant to the turbo, the intercooler and the control system and extra sensors on turbo engines all add up to increased repair costs and difficult access. Broken exhaust manifold studs causing exhaust leaks on turbo motors often lead to expensive repairs also. No such thing as a free lunch!
Great point about engine oil now used not only for engine lube, but turbo lube, valve timing, timing chain tension. New cars having high performance, acceptable emissions, high efficiency, good economy now use turbo aluminum race engines. These complicated high spec engines features are sales tradeoffs to high maintenance, expensive oil change features. Owner right to repair only extends upon how much your willing to pay for a scanner with latest ODB2 updates for your car model.
Thanks for that.
He mentioned that the advantage of having a turbo is increased performance that you can’t get out of a naturally aspirated engine. The problem today is they’re making engines way too small and way under powered and adding a turbo charger just so the engine can make enough power to move the car. So you get the added stress to the engine without any horsepower advantage.
They’re replacing 250 hp V6 engines with 150 hp four-cylinder turbo engines .
It seems like it’s really a bad time these days to buy the average gas powered car.
The main reason they’re doing this is because of the overly strict EPA ratings for MPG and emissions .
Great Video, The Oil Geek channel here on youtube will teach us everything we ever wanted to know about engine oil quality and additives.
😬
Used to own: 2018 MB GLC300 Coupe comes with I4-Turbo. Purchased a 4 year (4 times) dealership maintenance package, which is like $250/interval. Daily driver with 91 oct premium fuel, and yet the engine failed at 30k miles and dealer replaced the long block under warranty. Also the tires are serrated and thus cannot be rotated, but needed replacement after 20k miles, which is like $350/tire Run Flat.
I have a 2024 Honda Accord EX with 1.5T engine. I use only 91 octane fuel and after 10K miles, I have had zero fuel/oil dilution. Even though the vehicle can use 87 octane, I did some research and found that 91 octane fuel eliminates the fuel/oil dilution issue and so far, it's working.
I watch your channel for a while.. Here is the deal...2016 gla 45 owner. Well maintained. over 100k miles. zero issues with the engine. repairs: oil pump and thermostat
Thanks for your clarification in regards to the initial workings of Turbo charged engines and the pitfalls that accompany them.🏴🇬🇧😎👍🍀
ngl..probably one of your best videos I've watched
You’re one of the few that I listen to. I agree with everything. I had a Mitsubishi rally art. Slightly modified. Never a problem. It was to the floor every day of its life. Never a problem. But, I’m not typical. Oil change when dirty. 3000 miles is typical. Always best synthetic oil. Even had a Chrysler 2.7. Bought used at 100000. From mechanic. Drove it 25000 sold it for what I paid. Never a problem. Supposed to be a terrible engine . Also had the 1.4 Chevy. Modified by dealer. Never a problem.
I bought the 2021 Mazda CX-5 CE Turbo w/ AWD because I didn't want cylinder deactivation, which can also have problems. Before I turn off the CX-5, I'll let the engine idle for another 30 seconds. So far, no problems with my turbo.
Love your videos!! Always something to learn from you.
Keep up the great work!!
Nice video man very Educating. Well done.
Great explanation of how the different turbos are cooled by oil and antifreeze
Couldn't agree more. Very good info for consumers. 👍
I had a SAAB99 turbo 2.. a limited rally 2 door. (1980)
The turbo never gave trouble, but exhaust valves could burn out as there was no intercooler or a low grade of petrol was used.
Cheers
Great topic. Could you do a show on supercharging?
And all the semi trucks driving is all highway...far less wear and tear with sustained highway driving...10% of city stop and go.
True. My company gave me a Freightliner with only 15 miles. I used it upto 650k miles and they traded it in for a newer one. Engine had the same power as new. It could probably hit 1 million miles. The only problems were electrical ones.
Thanks, Mark! What a lesson 👏
Thank you for watching
I love my Audi v6 Na 3.0 30 valve, port injected reliable power. Decatted with a milltek manifold back exhaust, she goes great and sounds incredible.
My Toyota 8NR-FTS 1.2 4 cyl turbo is liquid cooled which helps, along with the 5k changes.
Big time production value.
I learned a ton. Thanks
Boost pressure is also a big part of it to. VW 1.4tsi engines have low boost pressure. The highest output being 17psi. Well, atmospheric pressure is 14psi, so these things can run big mileages. With 10,000km oil changes(not 15K as recommended by VW)you'll have a long time ride. And mechanical sympathy helps at the same time. 😂😂
Good job on this content Sir. Cheers from NZ
1.4 tfsi is an awfull engine
People also need to be able to take care of their vehicles,some turbo engines are breaking down because of the lack of maintenance
I am a fanatic maintaining my cars you have to be to own a turbo. The oil intervals have to be on time.
Ive used Mobil1 EP and their filters for 15 years with hundreds of thousands of miles
Subscribed instantly 🖤 great information
Thanks for subscribing.
Great info.
Valuable info as I’m brand loyal to Honda. I have some research to do.
Glad it helped you.
My brother-n-law said the biggest expense he had on his early 90's turbo Ford Probe was speeding tickets, lawyers, insurance raises, etc...
I have a 2017 CRV. 170000 miles with 1.5 turbo. I change oil every 5 K full synthetic and air filter every other oil change. It runs like a champ. Never had engine trouble. I wouldn’t buy another Honda due to other issues but the engine has been great.
You've had a good run with that one!
I have a 13 ST Focus original owner. 210k on it. 5k on oil changes. I have never put anything but 93 octane. Most importantly, I keep the rpm's up. Low rpm is certain death.
WHY?? Because those itty bitty engines are being overworked.
It’s not the oil, it is the extra strain on engines not meant to make the kind of power they are asked to make, and powering cars they were never designed to power.
Stress in the engines
Excellent video! I learned a lot and I thought I knew it all. :-)
Thanks for watching.
Good Video, Exotic Car Play Place, Thank You.
You are most welcome
Turbo - change the oil early and often. Use severe service intervals. I have had turbos run like new on a car with 134k miles. I ended up selling it. Kind of regret that. My wife does not put many miles on her car so I change the oil every 6 months.
Thanks for sharing
A video ALL non-NA engine owners should be required to watch before purchasing
glad i got a 2021 explorer with the naturally aspirated 3.3 v6 plenty of passing power and less stress from it not having turbos
I agree
I do not have any turbo charged vehicles. I have a 2018 Ford Explorer and it is running great, no turbos. I just got a Ford Escape hybrid, also no turbos. I also had a company vehicle. It was a Mercedes Sprinter van. It was diesel and also turbo. At 30 thousand miles the turbo failed. At 63 thousand the turbo failed again. The final failure happened at 86 thousand miles. The transmission failed this time. This was a fleet vehicle and was maintained properly. I had to bring it in every 3 thousand miles for oil change and general maintenance. My company is retiring my van and soon the rest of the Mercedes Sprint vans. They are moving to the Ford Transit diesel and also the Ford Transit electric vans. Thoughts?
Even the maker of the notorious GT-R said it to change the oil as soon of 3,000 miles after that you just degrading the oil more…
Indeed
I own a 2008 Volvo V50 T5 with a 5 cylinder 2.5L motor rated at 227hp. while that's not super powerful, it's in a car that's about the same size as a Ford Focus (It was assembled in a Ford factory in Belgium). I like the broad power band-it, pulls strong though out the rev range. It's the only car I've driven (compact size) that rarely has to shift down when pulling a grade while on cruise control.
Yes they are great cars and I love the styling too
Top notch video. Thank you.
Always great content sir.
He's right. That's why I left MB when I sold my e350 V6.
The last of the decent ones
@@ECPP Brought one of the last N/A 6.2 V8 2022 Camaro's.
@ nice
Exactly why I purchased a 2024 Ram 5.7l hemi and not the 3.0l twin turbo 6.
Right, we don't need a 6 with twin turbos for everyday use. Adds too many points of failure and an uncertain future reliability. Bought a 2022 ram new with no e-torque to keep things "simple". Still have all the computers, fuel injection and tech. 😢
I find it so hilarious. I talk to people that buy an expensive vehicle with a turbo and then they complain. Oh I don’t wanna use premium. Gas is too expensive but yeah I’ve paid $90,000 for a depreciating asset.
That’s a factor
I will have to say if you buy anything with a ecoborst and turbo when it is repair time it will cost you dearly for shop repair
Why turbos fail quickly? ABUSE. There is zero patience nowadays, so turbo owners will NOT idle their car for a minute before AND after driving. And - people do not do regular oil changes on their naturally aspirated engines, they surely will not on their turbos - that need oil changes far more regularly than the NAE.
I would agree there is abuse and neglect plus many who simply do not understand the extra requirements
@@ECPP I also like to watch "The Car Care Nut" here at TH-cam. This fellow is like the pinnacle of automobile guru mechanics. One recent video he had a late model white Toyota Highlander with 42K miles in his shop that had NEVER had an oil change - the guy was visibly hurting just looking at the SUV 😄
My 2018 Mercedes 200d taxi has 500k kms on the clock. Never had any big repair bill. A couple of sensors failed. Yes its the abuse that killes them together with bad maintanance
My GR Supra uses high velocity fans to cool its 3.0 i6 B58 engine WITHOUT the need to idle the engine at the end of your trip.
@@davepaturno4290 - these special high velocity fans probably don't exist in most turbo engines.
Great video - learned a lot
They aren't built to last much beyond the warranty period & most people are fooled into believing you don't need frequent (3K miles) oil changes on a turbo engine since the oil is effectively having to pull double duty in that type of design. Also, turbo engines need to be warmed up properly, cooled down properly & are not driven for a lot of short trips vs longer open highway miles.
Great job explaining!
They put tiny 3 and 4 cylinder engines between 1000 to 1500cc in heavy cars which are screaming near redline just to keep up even with local Walmart traffic then use ultra thin motor oil which loses viscosity due to turbo heat and high RPM sheer.
Some turbo's drive fuel into the oil. Some manufacture's were recommending 8000 mile oil changes when they should be 4000 miles.
Very informative video.
THE HELL WITH TURBOS . I LIKE NON TURBO WITH NO PROBLEMS.
I HAVE NEVER HEARD OF A TURBO LIVING AS LONG AS NON BOOST ENGINES.
THAT IS MY EXPERIENCE FELLA. HAPPY NEW YEAR FELLA TOO. PEACE vf 😀😀
Thanks for sharing. For a daily, simple is most reliable
@@ECPP Right on brother that is a fact.
Happy New Year too fella. Peace vf
@ happy New Year
This is why I went for a non turbo. Do i lose some power? Sure I do but I'm not racing and I can still easily do speeds high enough to lose a license on an interstate highway. People are spoiled. I remember a lot of vehicles use to barely be able to hit 90mph and some of them got quite scary at that speed.
My honda 1.5 I change my oil every 2.5k miles plus high octain fuel. Oil and oil filter are cheaper than an engine repair.
You are doing what you can.
@@ECPP I love my honda and by doing this I hope it lasts a long time.
My 2016 VW Golf MK7 1.8t is producing 243hp and 273tq with a Stage one tune with zero failures since I bought it new in 2015. Turbos need to be never used until the oil is fully heated and I always let the car idle for 1 to 2 minutes before shutting the engine off.
Bonjour , merci de nous rappeler toutes ces choses importantes . Presque toutes les voitures peuvent durer très longtemps si elles sont très bien entretenues .
Bonne journée .
Cheers
Small motors with turbos are an equation for failure. Great when new but typically they don’t last, particularly when driven harder.
Yes indeed
Hey Mark, I have an AMG with a electrified turbo, any idea how reliable these will be? Thanks for all the great videos!
Well the demand for NA engines is still here, but then the offering is mostly turbocharged .. in Europe at least. You can go either Hybrid/EV/or turbocharged petrol in the best case, or turbocharged diesel ( but then struggle with DPF as I did in the city, not only once) if you don't like to mess with electric cars. There is no other way around turbos. It's better for us, who do not want to have EV now , to learn how to maintain turbo cars. Thanks for the video, I enjoyed it !
Even with the correct setup a turbo engine will never outlast the normal version of it!
Great education!
Thanks
Turbo charging an engine is like pulling a wagon with one horse that’s on amphetamines. Works great, for a while !! Vs pulling same wagon w 2 horses not on enhancers. Uses more food/fuel but last much much longer ! My 2c
Haha
In England, the vast majority of turbocharged engines are diesels. All vans and trucks etc. All diesel cars are turbocharged too. These engines aren't particularly big, maybe 1.9-2.5L. These engines seem to be pretty good, as long as you avoid the German manufacturers.
There are a few petrols around with really small engines, 1.0 eco boost etc but they're breaking very early.
Dpf filters and the eco crap have ruined the newer diesels though 😢
Yes they are
Steve Carell: WTH are you doing. Call your agent bro.
I'm convinced ... stay away from the complexity, risk, and costs of a turbo charged engine. Give me the option of a less complex, less risky, lower cost, longer life naturally aspirated engine.
Its not just turbo engines. Even NA engines have this problem if you listen to manufacturers oil change intervals. Theyre setting stupid long intervals. My c63 has thr m156- basically a flat tappet race motor. They say 15k km intervals. Im doing like 8k.
Great video
Heat and pressure destroy engines, especially SMALL engines. Turbocharging creates heat and pressure!
It is a simple equation, more boost means more heat.
I like the older ones that i can do miner repairs myself
When most people dont even check or change their oil til its too late, maintaining a turbo is more work than a naturally aspirated engine. I'm sure they dont use quality parts or use assembly processes and tolerances that higher performance and more expensive engine use.
Best advice: Change the oil often with full synthetic. Also, if you plan to own your vehicle a long time (over 10 years/100k miles) don't get a turbocharged engine. Even the good brands like Garett, will tell you turbos need to be replaced within 150k miles. And that's a 3-4k job if you have a reliable shop do it right.
Turbos just require more frequent maintenance. If you do that your turbo will last just as long as NA engines. My friend has a Nissan Z twin turbo from early 90s and it still works fine. He just needs to not neglect maintenance which he does regularly
