I hate these oil threads, but I decided to give this it's own thread because I think it's worth it. Don't the new ralliarts use 0w30? Could I use it in mine ('04)? I know 5w30 is recommended, but that was in '04. Here's what Amsoil has to say: http://www.synthetic-oil-tech.com/d....weight_oil.htm . I realize hat they are two very different cars, but haven't found a definitive answer for this question.

FTR, I'm planning on using Mobil 1 0w30.



I wonder why everyone has a different idea about this stuff. I'm sure there's a lot of false info out there and it gets confusing. I'm sure we probably won't solve anything here, but it doesn't hurt to try.

 

5w20 is the recommended weight (the owner's manual is incorrect, there's a tsb about it) but really, 0w20, 0w30, 5w30, and 10w30 (in summer) are all fine.

 

Thanks Otter. You are gentleman and a scholar.

I looked it up to make sure it applied-lol

...but this case doesn't involve weed.

...and I'm sure you have kind eyes and a beautiful soul

I love urban dictionary.

 

doesnt involve weed? wtf.

 

There is no difference between 0W-30, 5W-30 and 10W-30 at Operating temp.

The only difference is at 32 Degrees F.
