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.
