Turbo Civic - Oil Suggestions

[jwb6658]

Hey guys,

I have been floating around reading this forum for a while and am finally ready to inquire about the oil you guys would recommend for my application.

I have an 08 Civic Si w/ 70K miles. I have an aftermarket turbo on the vehicle which dyno'd for 370hp. I have been using Mobile 5w30 for the entire lifetime of the vehicle and since it has been turboed (8K miles).

I didn't do as much reading about oils before I put the turbo on and I wish I would have asked these questions a long time ago.

What would be your recommended oil I should be running in the vehicle? Would it suffice to use a 0w30? I was looking at the 0w30 racing from mobile one, but it's pretty pricy. I would like something with a higher zinc content than what regular mobile one can offer me. If you guys suggest an oil that can't be purchased in an auto store, please let me know where it can be purchased..Thanks!

Welcome to BITOG!

The 2500 ppm of ZDDP is too high for regular street use.
What you could do is simply buy one quart to use as an additive to bump up the phosphorus level of regular M1 5w30. I wouldn't go any higher than about 1200 ppm of phosphorus.

What do you think about this article that Forced Performance put out about oils in high performing motors?

This is what has actually gotten me thinking that M1 5w30 isn't a good oil for my application..They recommend against the M1.

The Mobil 1 5w30 is a good choice for your engine; also Redline would be a good oil to use as well if you want to pay more. Mobil 1's heat endurance is outstanding, so I wouldn't see any problem sticking with that. I would stay with the 5w and not use a 0w since you have a turbo. Turbos definitely give an oil a good workout in terms of heat.

What is your typical driving style? Do you take this car to the race track?

As far as the article you linked to your last message, it sounds like they are referring to engines with 1000+ hp that are on the track quite a bit. The hp in your Civic, even with the combination of the turbo would not require a racing 20w-50 oil. Again it depends on how you drive your Civic.

What you could do is buy some of the M1 0w50 and blend with some M1 AFE 0W-20 (or any 0W-20 really).
1 qt of M1 0w50 and 3 of AFE 0W-20 will give you a 0w30 with about 1200 ppm of Phos, 450 ppm of moly and a higher VI of 177.

Personally I'd use the Mobil made Toyota 0W-20 for it's higher VI and AW additives as it will give a 0w30 with over 500 ppm of moly and a VI of 210; a killer oil IMO.

I would think something like M1 0w40 would be what you'd want to run in a K20 with 370 wheel horsepower.

 

[addyguy]

370HP is a lot, IMO, out of a 2L engine.

I'd use a 5W-40 HDEO (eg. Delvac 1), or a full-on racing oil.

Hey, if you're in PA, you probably have easy access to Brad-Penn's 'Penngrae 1' racing oils - they would work well here, I'd use the 10W-40 grade.

I agree with you except your mistaken about 0W oils having a problem with heat.
But yes Red Line oil would be a good option but only their 0W-20 or 0W-30, their 5w30 is too heavy being really a 40wt oil.

Oil that heavy would only be waranted if he was routinely seeing oil temp's in the 150C area.
If the OP doesn't have a oil pressure gauge he should install one and fine tune his viscosity selection based on that.

I baby the [censored] out of it. It will never see the drag strip or track..

Is there a VOA for that 0w20 you speak of? Where would I purchase that?

I saw the 0w40 had a VOA with over 1k zddp. That definitely an option. Any downside to running a higher weight? I wanted to stay in the 30 weight range.

m1 0w40 is a thin 40weight and can shear to a high 30wt.

is that 370 wheel or engine hp?

I'd be interested in a dyno slip from that.. seems impressive.


also the article you referenced contains swearing.. and isnt bitog friendly.. might want to read site rules since you are new here

 

[jwb6658]

BTW can I say that I really love this forum. The information is absolutely awesome and everyone is more than helpful! It's refreshing to not deal with 16 year old kids that think they know more than a seasoned vet..I won't mention other forums I read..

Sorry my mind sometimes slips..it's only 360 to the wheels.

I've seen that link before in another thread about boosted Evo's.
They're not recommending against M1 5w30 per se but light street oil with low ZDDP levels.
What they are wrong about is off hand recommendation of a 20W-50 race oil for street use; that's crazy considering
they make no reference to oil temp's or oil pressure.

 

[LeakySeals]

How is the oil consumption?

 

[jwb6658]

That was really my first consideration as well. They place all those different racing weight oils into this lump chart and tell us we can use any one of those.. Confused me because I was under the assumption the only difference with race oils is that it didn't have detergents that the conventional oils have..

Here's the VOA of the Toyota 0W-20:

Not surprisingly you can get the oil at any Toyota or Lexus dealer.

The problem with running a heavier than necessary oil and that may be the case with M1 0W-40, (although it is an excellent oil), is the increased oil drag and turbo lag when cold and for a street driven car that a lot of the time.
An OP gauge will tell you if you need to run a heavier oil and under what conditions it would be necessary.

Consumes very little oil. I change oil every 3k and I see very little movement on the dipstick..at least enough to require adding oil.

 

[jwb6658]

what do you guys think about Amsoil?

 

[A_Harman]

Mobil 1 5w30 has Honda's HTO-06 approval for turbocharged engines, so I think it would be a good choice for your car.

Mobil 1 0w40 has approval for Porsche's turbocharged cars.

Redline 5w20 and 5w30 have low volatility, high Flash Points, and no viscosity improvers to coke up your turbo bearings. Redline has high zddp and moly, too.
