Oh cool, another thread to make people stand in the isle at the store and read every bottle while scratching their heads.

It's motor oil, not a blood transfusion.

Rotella T6 is also widely used in late model Chevy stroker motors running extremely high compression

Gotta love these threads If unsure just go with what the current rating is for your spec(visc/weight/etc)...check UOA's and pick one you like that matches with a good rating.

So a $100 dollar oil change every 24,000 miles or 1 year is a waste?

^Just because an oil can still lubricate well up until 24,000 miles does not mean it will not become abrasive by that time.

I like to play it safe and not pass the recommended 7500mi interval, no matter what oil I am using. I would also be hesitant using "European Car Formula" oil on a Subaru engine.

Some of you guys are losing sleep over oils, and it's almost quite funny. Just use Rotella T6 and do 7500mi changes, but keep an eye on the oil level every now and then. SURPRISE! That's all you have to do.

Why? Because it has more Anti-Wear additives, resists fuel dilution, and stays in grade? Also, Amsoil 0W-30 is not a European oil if that's what you were referring to. It would probably be a better oil if it were.

Amsoil does not recommend going past 3,750 miles with any of their oils in a Subaru turbo. I ran SSO twice to 8k miles and had high oxidation and nitration.

They say that as a disclaimer. Subaru sent out a bulletin shortening their intervals due to the clogging of 2 screens. I got rid of those screens. I have been running amsoil In my 06 sti for just under 9000 miles. I had it tested at 7500 and everything was fine. I'm planning on changing at 10,000. Unless I pull another sample and everything looks good again. I just found what works for me. In my jetta I am just under 15,000 miles and all is well. That using their euro oil though. I personaly think amsoil is good stuff and will never chose another oil.

I'm very familiar with those screens but Amsoil doesn't make a distinction between model year or 2.0 vs 2.5. I'm sure it's to cover themselves, but I'd be interested in seeing those uoa's if they include TBN, oxidation, and nitration.

As a previous engineering major, I would be hesitant in using anything that was designed and then advertised specifically for a group of different automakers.

With more research in a specific oil, maybe I'd be more at ease, but with all the other good oils out there, like Rotella, I would have no good reason to switch off to an oil advertised for European cars.

Also, while the characteristics you mentioned are generally referred to as "Good" in engine oils, it's hard to jump conclusions that all oils labeled "European" would always be better than if it wasn't European, since we own Japanese cars.

As far as I am concerned, Japanese automakers tend to make their engines "tighter" and european automakers tend to make their engines "looser" ... which is why many european cars you see use a thicker oil than japanese cars. This is not always the case because we've seen GC work well in a Subaru motor, but just something to consider. But from what I've seen/read on here, GC is only close to a 40 oil, it isn't a true 40 weight oil. (Not sure if this is true, straight from nasioc )


Also I want to address one thing about those who say that 30 weight oils are bad because they shear to 20 weight. The people at Subaru who decided that the recommended oil should be 5w30 are the engineers.. the same people who designed/tested the motor and oils. They are engineers, they are not dumb. If they say that 5w30 is recommended, they already considered the fact that there is a possibility that the oil can and will shear down a bit.

and no, I wasn't referring to the Amsoil 0w30.

I'm not making any claims, there's just too many flawed logic in here and I'm just trying to maintain some integrity in this thread.

EDIT: I realize you said that European oils stay in grade. Being that the recommended oil change interval for Subaru is 7500 miles.. and even longer for some European automakers, do you have any data to back up that claim? I'm not calling you out, I'd just be surprised and pretty impressed if a 40 weight oil can stay a 40 weight oil after 7500-10,000 miles.

Default i hope i dont get flamed

So I've been reading all these posts and I haven't seen anything on the bulletin sent out by Subaru. Saying all 2011 and later cars with turbos must use Syn. Oil. Is this true or am i reading it wrong? I'm a new owner of a 2008 WRX and don't want to void any warranties. Its completely stock. I called Subaru and they said "the engine was designed for dino oil but synthetic doesn't hurt the engine. They also said if you use syn or dino the OCI doesnt change. I'm so confused on this issue. I will be changing oil every 3000. so it seems why run synthetic if my OCI is at 3000. Any clarification in lamen terms would be greatly appreciated.

^If you're changing your oil in such short intervals, you'll be fine with almost any good oil, dino or synthetic. Synthetic is required for my 2011 STi (2011 cars w/turbos - it states in my updated manual insert and on cars101 as linked below) but it was not for my 2010 WRX. Your 2008 WRX does not have a requirement to run synthetic only. As far as Subaru and their OCI requirements, it is pretty much to protect themselves from liability. Don't lose sleep over it - just use common sense: use a good oil, check it regularly and change it as required.
