- Adding to crankcase oil is the #2 use of Sea Foam (in fuel is #1) by professional mechanics and DIYers. Great intro video on how to do it - super easy!
#SeaFoamWorks
Added to oil, Sea Foam liquefies heavier petroleum residues and deposits back into fluid so everything drains away when it's time to replace the oil and filter. Pour it in every oil-change interval to keep oil flow passageways cleaner and help the engine last longer! - ยานยนต์และพาหนะ
This is a great product. My 2002 Sienna has been burning oil like crazy (like scary 4 qts (almost gone) every 100 miles). I did a piston soak (24 hours) with seafoam (nothing was left in the cylinders after the soak which left me to believe it went inside down to the oil pan) and did an oil change after 500 miles. I replaced the PCV because I knew I had a ton of blow by with the oil burning and stuff. Added half a can as part of the oil change. Drove the van on more than 1k mile vacation trip checking oil every 100 miles and to my amazement, no oil burn and the oil stayed full all the time. My MPG went from 12 to 22 MPG as well. The heavy noise coupled with engine that seemed to be under a lot of load on a smooth flat road was replaced with smooth sound and performance like a new engine. This has 150K miles only but is 18 years old. I am thankful that my van is back to where it was and this half can seafoam will be part of my oil change from now on. This shit really works!!!
So the piston soak! Do you just take out the spark plugs then pour some in? And let it set 24 hours?
So when u do an oil change you add seafoam??
Born yesterday 😂 found out they got a high mileage can too. Already put the white can in my gas tank. Wanna put the( HM.) In oil crankcase to see if it will quite engine you know the feeling of seeing your dashboard vibrates at every lite 🤯✌️
Half a can seems like WAY too much. Only need 1 Oz per 1 quart of oil in the engine
And how much time do you run the engine with that???
I maintain several UTV's (Polaris Ranger, utility vehicles). We add Seafoam to these small engines before oil changes and into the fuel system. You would not believe how much smoother running and more responsive these engines became since starting to use SEAFOAM.
Well those are tiny engines. No wonder the effect is much more
I have been using Seafoam in my 2001 MB E320’s fuel system about 10 years now, every 6 months a full can goes to tank close to oil change. For the last 2 or 3 years I also use it in the crankcase, couple days before the oil change, my car takes a little more than 8 qts oil and I usually get 2 cans a week before the oil change, 3/4 of a can goes to crank case and the rest goes to fuel tank, like I said 100-200 miles in couple days then the oil change. I can swear after the oil change you can’t hear the engine from inside, quiet and idles like a clock, car is almost 20 years old, 220K on the clock.
Seafoam is a good product.
So u dont do 1 ounce per qt?
Always! Added to oil, gas, vacuum line and sprayed in the throttle body! I do this on every car!
I'll try this one...but don't worry Scotty,i still have my toyota!!!
😂😂😂😂 rev up your engine 👋
Did it made any difference? Wich one?
Not for long if u ask Scotty lool, I just put marvel mystery oil in my celica will find out in 300 miles
@@williamburndred6284 what's the update?
@@MikaFaye. ill let you know next weakend if it stopped oil burning, though i can say it is great at removing carbon as i did 444+ miles and it was filthy , looked like a 10k mile oil change
Been using it for 50 years and it works great
What’s your control group?
My motorcycle was running on 1-2 cylinders (out of 3). Fellow rider recommended Sea Foam. Put contents of one bottle in the fuel tank. Very short time after running engine, it ran VERY smooth. Will get more for my auto. Looks like this additive really works. Thanks
Right on Donald - we're believers too!!
Thank you for making this video very HELPFUL 👍🏽👍🏽
Aunt Barbara adores you!
seafoam products work! i used it on my 2003 civic and i could tell it runs smoother. did i also mention their excellent customer service! thanks Jim!!
Thanks, Lodi 22 - Pleased to hear + thanks for using Sea Foam!
Did you put it in the crankcase with the oil?
I have a 2003 RAV4
I use this on all my cars. I even made a couple videos on my Scarz Carz TH-cam channel adding it to my Audi. I learned a long time ago that its the safest for European cars compared to other brands. Thank you Seafoam for a great product.
Quick question; do you add this to your motor or fuel tank?
@@Ravenwest9876 I add it to both, usually at oil change times. About a hundred miles before oil change I'll put it in oil, and add it to fuel when I do change.
@@joemartin3240 thanks sir
Only product I use! Good stuff!!
I like how the directions in the video match up with the directions on the can.
If I could add a pic/pics I would...did injector job on 02 LB7 Duramax in June ..it is almost 350,000 miles ..under the valve covers are spotless!
Thank you guys for your help over the phone. The guy I talked to was very helpful and answered my questions perfectly
I did this yesterday in my 2002 Toyota Camry. Drove for 150 miles, then changed the oil. The oil came out extremely dark and VERY liquified! I also added the intake Seafoam spray. I can definitely say that I noticed the engine is a lot quieter
I run a can of this in my 2-stroke Paramotor every 10th or 12th flight I do. Every time I go to rebuild the carb and replace piston rings I feel like I'm wasting my time; it looks pristine, especially right after flying on a can of this. Absolutely recommend for any 2-stroke applications to get rid of carbonized 2-stroke oil residue!
Love that story!
I use it past 2 years in my oil no motor problem.
Im doing this as we speak, been noticing rough idling but no light so I’m putting some in my gas and oil now.
Seafoam cleaned the oil sludge out of my Audi A4 with 1.8T engine. Great product. I had a weird check engine light come on in my Nissan. It promptly went away after adding Seafoam to the gas tank.
Good to know-- I've got a Passat 1.8T, same set up with that sludgemaker turbo. I'll have to try this soon!
D’yer maker where did u put it on and did u put the whole bottle?
@@undercoverrt4106 For the 1.8T add it to the crankcase, or same place you add the oil. It will clean out the sludge and let your oil pump work. The sludge stops up the screen on the oil pump. I don't remember how long I let the engine run with it in there.
@@undercoverrt4106 yes, whole bottle in crankcase.
@D’yer maker did u put it with the car on or off?
I have 352,344 miles on my 02 LB7 Duramax...i did injectors on it in June..under the valve covers it is spotless! We have a 2013 hemi powered Citadel Durango and added it and ran it for like 600 miles before oil change(I did thus on my own) ..runs just fine. If your wonder what oil I use,Mobil extended performance the gold label 5w20 and mopar mo899 oil filter
I have a 2011 dodge citadel with a p000b code
About to pour it in my crankcase 😊
After a good fwy run, I poured some down the carburetor of my 1983 Corolla & it cleared lots of deposits. No more dieseling (hesitates to shut off after turning off at ignition switch)
Great news - thx for sharing!
Wanting to try this on a 150k 02 Corolla that burns a wee bit of oil but compresses perfect. 1zzFE with that nasty piston ring clogging issue most likely. Good to do 2000k oil changes with this on the final 300 miles?
Yes + check out Sea Foam High Mileage for your Corolla.
I want to add this to my 07 Hyundai Tiburon to clear out sludge before I convert it to synthetic oil but I'm nervous because some people say they have major issues after adding it, my motor doesn't leak and runs good though so would I be fine to add this?
People are describing old engines with leaky worn out gaskets. I doubt you have those problems. No worries.
I used a few ounces in my crank case and added half a bottle to gas tank at 1/8 fuel remaining. Drove like a banshee out of hell (safely) and I am glad to announce no check engine light or adverse effects.
(Edit-06 gm 3800 motor
I've got a 2007 ram 1500 with the 5.7 hemi, recently replaced the rear main seal and oil pan gasket, replaced the oil pressure sending unit but still deal with low oil pressure when the truck is fully warmed up but it runs really good. It has 165000 miles on it but im worried because the crankcase had a thin layer of built up sludge in it thankfully no metal but some build up, so I'm skeptical when I ask will this product clean up my engine and solve this pressure issue? Running down the road in cruising gear oil pressure is 51 psi. What do you think?
Hi Shane: Sea FOam in oil works to reliquefy any heavier residue or buildup so it can drain away when replacing oil. If you like that idea, use it! Hope this helps!
I haven't bought the product yet but will be very soon, but I did have a question. When using seafoam, which method is most effective? And also will I need more than one can if I wanted to put some in the oil crank case and the fuel deposit tank? I don't know the recommended dosage instructions yet but I'm sold on the products ability to work.
Both are great. Adding to fuel vs adding to oil is not a either/or. Best to do both.
Hi could you do some videos with the new and old domestic cars
I have a 4.8 ls motor in my truck and I’ve used seafoam in my oil with good results but my truck has been sitting for awhile.
What’s the best way to get rid of the sludge? Should I add seafoam before oil changes then change the oil prematurely to expedite sludge removal?
All you do is add half a can of Sea Foam to oil every interval. Will progressively clean the harmful residue and sludge from your crankcase over time.
Seafoam is indeed a great product for sticking injectors and piston rings,.
However there is a better way to prevent 'the sticking': simply change the oil BEFORE the receommended change-out. If youre driving mostly at full highways speeds and also drive at constant speeds, the recommended oil change-out is probably OK. If you are driving in city conditions and mostly for 'short trips' ... consider to change the oil at HALF the recommended interval ... so the carbon, varnish and other 'crap' doesnt build up 'behind' the piston rings ... and then cause adverse wear of the cylinder walls.
Can i add this to the crank case if ive already added some at 205 reseal beforehand?
Yes, supposing 205 reseal is compatible with motor oil.
i’ve got a 14’ fusion and the ticking sound when idle drives me nuts will this help? and can you only use it right before an oil change?
Add half a can every interval. You can also add any time during the oil interval. Easy! Lifter noise typically fades away within 100 drive miles or sometimes 2 or 3 treatments.
Can i run my truck wt that or i have to doit like a fluch and change my oil fast or i can use as a aditive and wait till my nex oil change?
Thanks for the question! You always want to drive at least 100 miles with Sea Foam in the oil before replacing oil. You can drive the full length of the oil interval if you wish. Hope this helps!
I have a 2004 Toyota Camry with a 192000 miles my wife bought brand new in 2004 it started using some oil not much to very good car ever since I've done this sea foam treatment I have not had to add 1 drop of oil Unless it's a coincidence I'd say the sea foam really clean some deposits out the engine ...now I do it to all 3 of our vehicles our 2018 Toyota rav 4 and my 2013 Ford F 150
Question: wondering if you can dispel this:
Somebody told me to not use this on older vehicles, because sometime that sludge is covering up leaks. And when cleaned will expose the leak...
what do you say?
Thanks
Great question, thx. My answer: Whatever was suggested supposes that all old vehicles have leaky seams that are sealed by sludge. It's true that some might, but more likely not the case at all. Sort of like telling someone to NOT go to the dentist for a toothache because you're too old. Anyway, I would never hesitate to use Sea Foam in oil. Hope this helps!
I started using SeaFoam about 2 years ago on my 2001 civic and it's worked wonders. I'd toss that myth you were told out the window. SF also makes it for High Mileage cars if you're more comfortable with that.
If wore to use seafoam in the rear differential to flush out all the gunk would it damaged anything?
No worries.
Is there anyway to buy directly from You guys or do we have to go through a retailer?
We do not sell direct. Thx for the question!
I pour this in a couple days before my next oil change ?
That will work. Just make sure you drive at least 100 miles to allow it to circulate and clean!
Since I just had an oil change, is it better to add to seafoam to my fuel instead of in the crankcase? I don't want to have to get another oil change in 300 miles
Great question. Yes, can add to fuel. Can get another can when closer your next oil change.
I got a noisy lifters or something checking on my 2002 avalanche with 121K miles. I hope this does the trick. I always have the oil changed in a timely manner.
Keep adding half a can each interval. It will work if dealing with lifter varnish!
How can you tell how many ounces to add? Are there markings or visual aids on the side of the bottle or is it better to use a measuring cup and a funnel? Thanks!
I just eyeball it + feel the weight of the can. Does not have to be precise.
I've always heard an ounce per quart of oil.
I use an old pint mason jar with oz markings. Now dedicated for seafoam.
So do you use regular seafoam even though you have a high mileage vehicle or do you use high mileage seafoam? This is obviously to put in the crankcase
Can use either. High Mileage is tougher on stubborn residues.
I just added this stuff after a fresh oil change. Can I leave it in there for the full 3k miles before my next oil change?
Yes, can do!
Can you put it in crank case and gas at the time? Or only one?
Yes, can add at the same time.
Its recommended to add this 100-300 miles before an oil change...my question is if I'm adding it to my ATV crankcase...diving 100-300 miles is going to take a looooong time. Does it still do a good job cleaning if I add it 50 miles before oil change? Thanks
For an ATV figure 60 minutes of operation with Sea Foam in the oil. Hope this helps!
Question: Does it evaporate?
Let me explain: I added the appropriate amount to the crankcase but couldn't start/run the engine for 2 weeks due to an unrelated issue that I fixed later. Can I then assume that some of the seafoam evaporated since the engine didn't turn allowing it to mix with the oil? Should I top up? Pls let me know. Thanks.
Sea Foam is petroleum oil - it will not evaporate from the crankcase so good to go/nothing to do.
can B-12 chemtool be used in engine the same way as seafoam?
Not the same thing.
Do you to drain out any oil (so you don't overfill) before adding Seafoam?
Hi Kevin. No need to drain any oil. Plenty of room for half a can of Sea Foam.
If I just got a oil change can I still put it in there already put a fan in my fuel tank a couple days ago
yes, can do 👍
Never used Sea Foam before. Sp adding more product to oil will not cause "overfilling" the capacity of the oil? For example, if the vehicle takes 5 quarts and there are already 5 quarts of oil in it, won't adding anything overfill the capacity?
You're adding 5 oz to 160 oz of oil. No worries.
Does any of these Seafoam help with spark plug deposits
Yes, Sea Foam Spray treatments in particular.
Will this help sticky internals, like rings and lifters, rockers?
Yes!
@Richard Pedroza marvel mystery oil thins oil
One of my cylinder is having low compression(1 out of 6). Any of sea foam product can help with that?
Sea Foam Spray treatments through the intake and adding Sea Foam to oil each interval. Both work to diagnose stuck compression rings that are gummed-up with varnish/carbon.
Can you add seafoam to new oil and leave it there until the next oil change? ( 4000 kilometers ) give or take?
Yes, can do!
My car takes 4 liters of oil and tends to have a somewhat noisy valve train until the oil gets flowing. I just changed the oil and filter though and I'm not sure if putting some Sea Foam in on brand new oil is the best thing as the oil will become very dirty fast. Would the dissolved sludge in the oil cause extra wear or would the oil filter clean the harmful grit?
Hi Brock: No worries - just add half a can and let it work until ready to change oil.
If it looks really dark just change it. Even if you haven’t reached your interval. Oil is cheap, engines are expensive
I just changed my oil on a ford explorer that is burning a quart of oil every 500 miles. I want to add this to the crank case before the next change, but that might not be for 6 months. If I dump in sea foam and let it do its thing for say 7000 miles will this be bad? Or should I just add it, drive 300 miles and change the oil and filter again?
You can add at any time during the interval. No worries.👍
Is this product ever bin used on a 2004 acura tsx ? Just want to make sure because I know how acura engines are so delicate
Yes, can be used in any gasoline or diesel engine!
If I use an electric oil extractor to change my oil through the dip stick, I know it will leave about 1% of oil behind. If I use seafoam, will the liquefied sludge be able to go through the thin tube on my oil extractor? Is it safe to leave behind that tiny 1% of oil?
Great question. Anything Sea Foam cleans will blend into the fluid oil phase, so yes.
I put 4 oz for my honda accord 1998 4cyl and then I drive it 10min, check engine light turn on. What do I do with it ?
I would put a code reader on it to find out what prompted the CEL. Most auto parts stores will read a CEL code for free.
Hi
I put one can of seafoam in my car crankcase 4 liter capicity and 2.4 engine model because it is burning oil is it safe let it for longer time till the problem solve?
Adding Sea Foam to oil is ongoing, so add every interval.
is this recommended for GDI engines too?
Any oil crankcase! Injection system makes no difference.
So can I put this in while I’m doing the oil change?
Can add right after you fill with new oil.
is it safe to suck through a vacuum line for brake booster?
We do not promote using a vacuum line. Not safe because you can hydrolock a chamber and ruin the engine. Use Sea Foam Spray through the throttle body.
Can I àdd 1 to the tank and 1 to the oil at once??
You can add to fuel and oil systems at the same time. Not sure what you mean by 1... If 1 can to each, adding 1 can to most oil systems is too much. For example, a 5 or 6 quart oil system should use half a can (no more than 5 to 8 ounces).
Is it ok to add and let it sit in there for lets say 5 -20 miles trips over a month?
Yes, you always leave it in till the end of the oil interval.
Can it be used in a prius/ bladder gas tank
Yes, any gas or diesel fuel tank or oil crankcase.
If filling in gas tank, am I supposed to add bottle to an almost empty tank and run the engine? Or am i supposed to add seafoam and gasoline together?
Great question: Add to fuel when the tank is lower (vs more or full), then drive at least 20 miles with the higher concentration before adding more fuel.
I put a can in an almost empty tank at the gas station, then fill it up with gas.
@@MMID303 That makes no sense...LOL
So it works to crackcase and can be add or use also in gas tank,is that correct
Yes, both.
I have a very small leak in my rear main seal, wouldn't this affect the leak?
It might if the seal is clogged with old oil varnish.
I run this on my 600 miles before every oil change and my car has 250,000 miles still going strong
Very nice! 👍
You add it to your oil & drive 600 Miles then do an oil change?
I don't drive that many miles can I add Seafoam and change my oil a week and a half later?
Prior to changing oil, most important is to drive 100 miles minimum after adding Sea Foam to oil crankcase. Sea Foam needs engine oil heat and enough circulation time to work.
How do you keep it in the crankcase? It just runs down into the oil pan.
Sea Foam is oil so it mixes evenly with the motor oil.
Added more than the recommended amount, would that help clean the internal engine better? My 305 cubic inch Chevrolet engine is extremely gritty.
How much did you add?
I added the one ounce per quart of oil, 5 measured oz. question is added MORE would help my extremely gritty 305 engine.
@@barrypowell829 For a 5 quart system you can just eyeball half a can. A few more ounces will help a little.
@@SeaFoamOfficial
Added whole bottle to a 6 quart system?
@@justinmitchell553 Keep an eye on the oil going dark. We recommend replacing the oil if you add 2X amount.
Ok but shouldnt i drain out oil? Adding this to my oil will raise my oil level past the full mark, right?
There's a lot of room in any oil crankcase to add half a can of Sea Foam. No worries!
I use seafoam before oil change, i dont put it in fuel anymore as i started having cat / o2 errors after putting it in gas (was coil errors causing missfires - reason i tried seafoam thinking injectors were dirty).
Then i run my mowers on that dirty oil for 20 mins then fresh oil in them all.
Hi David. FWIW, Sea Foam has absolutely nothing to do with cat. converters.
If I’m adding to my Duramax do I replace a quart with that and leave it like that for the whole duration of the oil change or does it burn up and I will have to add a quart of oil later?
Hi Steven: Just add it to the oil. Sea Foam IS petroleum oil. You can leave it in for the life of the oil and it remains in the oil until you drain the oil.
My car has a short knock when it starts. Will this eliminate that.
Engine knock occurs in the chambers, so Sea Foam Spray treatments would work best. Adding Sea Foam to oil won't help knocking. If you're hearing lifter noise (rapid ticking), try adding half a can of Sea Foam to oil every interval...the noise will fade away quickly or might require two or three intervals. Hope this helps!
Would this work for low oil pressure problems?
For sure. Add half a can to the oil and see what happens after a few days.
Hi. What is the difference between regular SeaFoam Motor Treatment and the High Mileage version of the same product? How are they different? Is it a matter of different formulation or just concentration? Please enlighten us. Thanks
Very similar. HM is tougher on stubborn deposits.
Hi please help, i poured in all the bottle in my engine oil, is a 6 cyl 3.7 liters, will this damage my engine? Should i change the oil immediately??
If you are concerned can either change your oil (complete) or drain 2 quarts and add 2 new quarts.
This saves francis my sl1 saturn from rod knock my saturn get bad rod knock every 10k kilometers and I just give it some sea foam wait a day run the engine 10 minutes and change oil it always stopped the knock and will until 300k
do you have to heat up your engine first?
No. You can add this additive before or after engine start.
Can you put this in a Honda gx240 motor?
Yes, can add to ANY gas or diesel fuel and motor oil.
Should I do this on my 2007 Lexus Is250? I just want to clean it out but I'm afraid if I do do it, It might create leaks.
What do you suggest?
Why do you think you have leaky seals?
@@SeaFoamOfficial I'm not sure if I do or not. I just feel like it might do that cause it's an older vehicle haha.
I've just never used it before.
@@Mag1c4lyfe Am very doubtful that you have leaky seals.
Just poured a whole bottle of this to my gass tank 😂 omgggg
What do you mean omg? Seafoam is tried and true
you mention adding at 'any time' but recommend '1-300 miles prior to change.' So it's not advised to go longer as an 'oil additive' as it'll dilute the oil recommended by manufacturer?
It does not dilute the oil. Like when we clean our teeth... Can be done any time, but there are more ideal times based on our daily routines.
Does it help with hard start Honda crv? 03?
I'd get a can of Sea Foam Spray and 2 cans of High Mileage. Add half a can of HM to the oil, 1.5 cans to a very low tank of fuel, then do a Sea Foam Spray treatment into the throttle body - easy to do on a 03 CRV. Do all that and let us know how it works after a day or two of driving!
Can i drain the oil, leaving the oil filter then add 3-4 cans of seafoam on idle for a few minutes? Or would it do harm, tryijg to do it on an 88 chevy silverado
Do not do that. Will likely ruin your engine. Never run an engine with motor oil removed from the crankcase. Be patient: Add half a can every interval.
@@SeaFoamOfficial thank you, for getting back, i will wait and do it like its suppose to be, thank you
@@spartantony1 Our pleasure, always!
Never in your life do that.
What about to crank case of 2 stroke 3.0 outboard
A 2-stroke does not have a closed motor oil system so no need. If your 2-stroke is oil-injected, you can add Sea Foam to the oil fill tank.
I have a 4.2 qt crankcase and am due to change my oil about 300 miles from now, i tend to burn some leaving what I estimate is about 3 qts after top up each interval. in the case that its less than that, is it safe to go over a couple of ounces? thanks
Yes, a half can is fine.
@@SeaFoamOfficialwhat if i poured all the bottle??, Please help
@@thunderwolfgt79 Change the oil or drain 2 quarts/ add 2 new quarts.
I have 2700 miles left for my oil change. Is it okay If I put it in now?
Yes, OK to add any time during the oil life.
could you add this to a motorcycle? will it interfere with a wet clutch
I cant see how besides you only want to go 100 miles or so.
Works great (and safe) for a wet clutch.
I just put a can high millage sea foam into my Prius gen3, 10 Oz goes into my 10 gallon gas tank, rest 6 oz on 5 quarts my crank case. after 150 miles driven. I noticed my engine oil turning brown. and my coolant dropped about half quart. does sea foam cause blown head gasket? what should i do now? any suggestions?
Hi James: If your coolant is low and oil is milky brown you likely have coolant leaking into your oil crankcase. No, adding Sea Foam to oil would not have anything to do with causing a failed head gasket. Get it looked at and evaluated. Let us know what you figure out.
Add in the glitter after a coolant flush good to go till you save up for a head gasket repair that’s costs a thousand or more to replace in the shop.
Ohh n after that change yer wet spark plugs after your glitter stopped the leak should be good to go. Cause you will burn out the excess out the tailpipe
I had a knock on cold starts on my 2001 Silverado and this eliminated it by adding to the crankcase
Was your truck smoking. ? Before use ?
Did u add it to tank or oil?
I had that same knock on my 1998 Cheyenne 1500. I used Motor Kote and after 100 mile or so that knock is gone. I will use the Seafoam on it next to clean it out.
@@vicreyes9237 he said crankcase, so I assume oil.
Can you put in in engines used after 2017
Any engine, new and old!
How much will it thin oil ? It will cause marvel mystery dose
It won't thin oil if you use the recommended amount.
What would happen if you put seafoam in the crankcase at the start of a fresh oil change and left it? In the video it says 100-300 miles BEFORE an oil change. So would putting seafoam in directly after an oil change, have any effects opposed to just before changing oil?
That would be fine.
@@SeaFoamOfficial okay thank you!
I must have not read the directions properly because I've been only using it with new oil, yet it still works wonderful and better than it used to. I drive a 2001 civic.
This was the question i was gonna ask😅
@SeaFoamOfficial is it better to wait till before the oil change is due or do it right after?
I wanna try this on my Toyota pickup 84 it has 95k but car was sitting for a while please help we’re doing I start and I just had oil change when do I add it?
Add it where you add motor oil. Just open the filler cap and pour in half a can.
Should my car be cool? And do I have to drive immediately??
Does not matter at all. Can be hot, cold, whatever. Just pour it in and change your oil a week later, whenever.
Can you run seafoam in your crank case for the full 3000 miles will it harm your engine
You can do that! Will work great, no worries at all.
