HI guys, I want to service my series 5, what's a good engine oil to use. thanks

 

castrol GTX. Ive never used anything else

 

pretty much anything non-synthetic will be fine.

 

Castrol GTX has a very good long-term record of protecting rotary engines.

Modern synthetics are just fine, but are a waste of money in most cases.

 

Castrol GTX FTW

 

If you feel like going the whole nine yards, go with redline or royal purple. I'm currently running redline and its great.

 

Chevron. I use it. It works.

 

stay away from Royal Purple. Long term use, it leaves sludge deposits. Studies have been done. You can't suspend molybdenium Dysulfide in a fluid state. It WILL settle with time. I think GTX is good and cheap. if you have money go with Redline, or Amsoil.

 

whats about tuned engines?

10w60? 5w50? sytethic + 2stroke oil/fuel mix????

cause my turbocharger is sounding very high... running aprox 8,7PSI and stock exhaust and stock 10w40 engine oil!!!

This is asked weekly. Please just search for "oil recommendations" or "oil type".

Closing thread, and will be adding this info to the FAQ soon.
