oil question for ported s5
Everybody has their own opinion and its really just one of those things you have to decide for yourself.
The one thing everyone seems to agree on is; if you go synthetic don't use the cheap stuff.
Also, most people agree that royal purple is the best, or at least in the top 3 oils to use in a rotary.
Personally, my engine is street ported with the OMP removed (Don't trust the electronic ones anyway) and I use castrol gtx 20w50 I think...
I'd search it if I was you because there is plenty of information on the forum about what oil to use.
