I've got an 03' WRX w/ 92K w/ a P&P Td-04, catless dp and otherwise stock. I noticed that I have been burning oil lately (a quart every thousand miles of Royal Purple 10w-40) but just today I noticed there was a lot of smoke out of the tailpipe. It has never smoked before today but then again I can't really see what's coming out of the tailpipe while I'm driving though. The car runs great and pulls very hard. I'm going to be doing a compression check next weekend to see what's going on but do guys think it might just be the Royal Purple or should I start saving for a new sb?

Oh, the turbo has only 2K miles on it. Also for the first 66K the original owner used 5w-30 which in Florida seems like its too thin.

 

Ringland?

 

ummm....why are you running 10w40??

 

10w-40 is way to heavy for factory motor...do a compression check but get the block to operating temp first...then quickly do it...yes, it will be hot but will give more realistic results. A leakdown test would be best though.
I wouldn't be suprised if the turbo's rear oil seal was shot.

 

5-W30 is whats recommended! i use 5-W30 royal purple. WHO told you to put 10-W40 in your engine....lol

 

I've read on nasioc and even in the owners manual it says that for hot weather/heavy loads 10w-40 was better to run. It seems like a lot of spun bearings are happening when people run 5w-30.

 

Man dump the royal purple get Mobil One Syn Works good for me with M-181 Oil filter

 

bill at mastro recommended motul the 40 to me... no problems with it so far

 

well, LD, we use 5w-40, not 10w-40. Also, motul ftw!!! thats some good stuff!

 

Ok cool guys I'm going to throw in Motul 5w-40 next weekend. Where do you guys buy your oil at? I'm going to order these https://www.subarugenuineparts.com/p...roducts_id=830
