Oil grade opinion please.
 

Hello, I have WORKS Stage 2 turbo kit, oil cooler, and running e85 flex-fuel kit.
I was told by WORKS to use 5w-30 instead of 0w-20 for engine oil. WORKS used ENEOS 5w-30 and the car seems to be running good for few months now. They told me I can use any synthetic brand as long as 5w-30.

Now its time for my first oil change since the turbo and I want to switch to Amsoil (based on many good reviews about them). I called a local Amsoil dealer and they told me to use 0w-20 and not 5w-30 because it will just create extra heat and may not perform as well as running 0w-20s. He said their oils are not like many other brands and are made to not break down during heavy driving and high temps.

I daily drive my car and do some spirited driving up/down mountain roads. I am not tracking my car but probably one day i might.

Can someone with more experience point me in the right direction? Thanks

your boosted and in CA. Stick with 5w-30.
Use motul

Run a quality synthetic 5w-30 from any brand you like.

I run Mobil 1 5w-30. It hasn't let me down yet!

As long as your oil temperature is kept in check (by an oil cooler), there's no reason to switch to a heavier oil. For whatever it's worth, I've been using either Motul or Amsoil 0w20 in my engine for about 45000 turbocharged miles (also with the Works kit) and a proper oil cooler. I haven't seen oil temperatures over ~190 while driving even in 90+ degree heat and I'm making (and using) close to 400 whp.

Run 0w20 on a turbo and youll blow your shit up. All boosted subis run 5w30 and never seen a boosted car run 0w20. I have see alot of QQ people running 0w20 and blow there shit up though.

I've ran 5w-30 for over two years boosted at 500+ whp, still running strong.

Yes, I've heard many stories of boosted frs/brz blowing their motor when running 0-20. Don't know the details of reason why, it could be numerous reasons. Some saying 0-20 if I have proper cooling which i do have oil cooler. And some say do not run 0-20. lol

Works do recommend 5-30 though.

Turbo's kill and break down the 0w20 oil as it passes through the Turbo. I don't care what the temp of the engine is but once oil gets to hot and breaks down its never the same, It needs to be replaced because it's properties is no longer valid.

You can look at any... turbo'd car on the market and you'll never see anyone running 0w20. I personally use the same exacted oil as the Forester XT or WRX uses from Subaru with there ej20, ej25 and fa20 turbo's engines. I also use the same oil/water block to bring the oil up to temp super fast and maintains the oil at the perfect temp for street use.

This summer has been super shitty at 100f and I was super close to dropping 5w40 in the car.

0w20 for NA cars is fine it heats up quickly. No 1000f turbo is heating of the oil.

If you have the money to rebuild your motor by not taking the advice from you turbo kit manufacture then go for it. It's kinda of fun to use the search on the forums and look at all the people who would go over and over about using 0w20 and then don't have any problems and BOOM one day they post a new thread "OH noes my motor spit out a rod!".

Also noted Subaru recommends oil changes every 3000 miles, which is way cheaper than a new motor & your time. Oils cheap, Engines aren't.
:burnrubber:

My first intention was to go with WORKS recommendation. If you read the post it was the AMSOIL oil adviser that told me to run 0-20.

Its good to hear some useful advice from this forum. The AMSOIL adviser went kinda nuts at me over the phone and saying that mechanics do not know oil and that AMSOIL does not break down like other oils, and also running 5-30 will just create the extra heat.

Maybe I probably change my mind go with a different brand.

No i run AMSOIL all my Suzuki GSXR's. Its great, i personally should run the 5w30 in my car.

Why do you have to shit-post everywhere

Yeah sometimes when he interjects I shake my head, then I look at his picture and see what looks like a confused bloke, consistent with some of his posts. He is polite though, most Brits are except, after the pub LOL

Motul 5w-30 to 40 for boosted fa20's

I'm asking this question because of what the AMSOIL adviser told me. You love to make these comments don't you. Please read post.

The CSG BRZ is boosted, and runs 0W20 300V.

It probably also is driven harder and abused more than most cars here.

I'm a Moblie 1 fan boy and I say all ya'll are wrong.
My MR2 Turbo uses 10-30. Totally unrelated. Also Amsoil sucks donkey ****. And Motul goes in for the reach around. Cause I'm not a fanboy of them.

It's just oil. Put some than nothing at all

Ok, on my previous car, lancer ralliart I've used mobil 1 only and it seem to be alright. Also Mobil 1 is everywhere, I can go to almost any auto store and buy it.

AMSOIL sucks? According to most of the people in this forum, they love AMSOIL and MOTUL. I am no oil expert and don't know if these high end oils really out perform your ordinary oil you can get at any store. I only chose AMSOIL because of the people from this forum.

You missed the total fanboy joke. Also most people on this forum can't jack up their own car. So...............

Joking aside,
Synthetic oil is pretty much the same these days. Side by side test all prove they provide far better protection than conventional oil. Brand by brand, pretty much identical.

The question is price. An example would you want to pay for a jug $25 at any store or $25 online +$5 shipping. Then which fan boy club you want to try?

I been a Royal Purple fanboy before. But then I saw a hot chick in a swim suit that gived me a Moblie 1 t-shirt. Amsoil and mutol girls are fugly and don't give away shit.

Hmm, if most synthetic are about the same then i might go back to mobil 1. Fyi i am also running flex fuel, mostly running e85, mobil 1 should be ok for e85 right?

I'll just leave these here.

Top one looks alright. Second one....eh.

Nope totally worng, you want oil from over weight little kids running on a treadmill. That's the only oil you should use. Nice and pure. Some hipster in a man bun told me so. You should too.

Joking a side, which info do you want to go on? from the company that did your turbo kit, or some sales rep?
Keep in mind your turbo kit is just an add on. The turbo will be happy no matter what kind of oil it gets as long as it has some.

Yea i just went with mobil 1 5-30 because its convenient. Seems ok so far.

i've been using nulon 10w40 fully synthethic. I'm not 100 per cent sure its the best choice but my mechanic told me to use that or 5w 30. I got the 10w40 for a good price so that was that. might change next time.

Revival

Im JDL Turbo'd i am on 5w 30 Motul but I am going towing the brz to Colorado soon.

Should I switch to 0w 20 because of the cold?

Same here @CSG Mike except my buddies and I don't track our cars, but we weekend warrior it on drag races.

I've been running 15k boosted miles with the Edelbrock Kit using the Toyota Synthetic 0w20 Oil. Eventually I want to change to Amsoil 5w20 as for some reason 0w20 isn't available, but it shouldn't be bad at all.

Some of my turbo friends running the SBD400X, JDL UEL Turbo, and Full Blown Turbo, run this platform use 0w20 and 5w20 with success.

I suppose these oils are fine for us cuz we keep our power goals under 330whp and boost @ 12psi or less with oil cooler / improved fuel injectors/pump for support.

I am supercharged, on e-85, 50,000 miles on the car and dozens of track days. I just pulled the motor for a blown head gasket. I have always used PUROL 10-40 and the bearings looked as good as new.

That's a bit thick for stock clearances.

Do you know the cause of your blown head gasket? Typically it's either knocking from fuel starvation (common with boost + e85 + left turns on track), or overheating.

IIRC, you have some cooling mods.

:iono:wonder if someone from a COLD place running turbo can budge in....

What does cold have to do with it, outside of cold start?

I'm not talking about anything outside a cold start...

Information based on oil to run with Turbo, and temperature on this platform seems a bit scattered. Talked to tuner and performance shop, they could only relate to it from hot climate (Florida). If I look at Subaru's charts separated by oil and model, well they're separated by models, so that's a NON Turbo BRZ.

Maybe I need to post in regional section.

I don't understand what youre asking. The car has thermostats to set a floor operating temp, and a cooling system to (theoretically) set a ceiling operating temp. This is regardless of whether the car is in -40F Canada winters, or 130F California deserts.

Don't really know Mike. Yes I have aftermarket cooling mods. My engine builder said he guessed the studs stretched from being boosted and the head lifted.
Been running 10-40 based on conversations with Phil Gabow at Element Tuning.

I did experience the fuel starvation issue one day at streets of willow, last turn before the straight. CCW, so that might have caused it. Normally I always top off my tank between sessions but that day I forgot to.

I've just heard of "cold start damage"... I'm running 5w 30 right now in FL, I've just heard if I'm going to be in the cold, I should get 0w 20 or 0w 30, I haven't really found any sources on that, or anybody that can relate to the matter.

5w 30 should be fine for you in Florida as it doesn't get too cold out there.

Sounds like it's time for a surge tank for you!

Sorry, I completely left out the fact that I will be taking the car to Colorado lol...

Says your turbo'd and in WA? What oil have you been running during winter there? (while turbo'd)

I used to run 0W 20, but have since switched to 5W 30 for the past 2 years. Our winters aren't too cold so I don't worry too much. Something that helps a lot is the Torque App that I downloaded, if you enter a custom PID (the thread is somewhere on here) you can get it to read you oil temperature for extra security.

If you live somewhere that constantly gets snow in the Winter, I would switch to 0W 20 for the Winter months.

Could be.

Ok, honest question, I'm a southerner so define too cold. Colorado is ranging from 20s to 40s right now.

I am actually running Torque Pro. An Oil pressure gauge would make me complete though.

I have 1000 miles left before my 3000 mile mark on my current oil (5w 30).
