Disclaimer: I know virtually squat about oil chemistry etc.
Now that that's out of the way, I have a 1989 Porsche 944 S2 track car (3.0l, 16 valve, 4 cylinder, 100,000 miles) and am wondering which is the best weight Mobil 1 to use. Most of the guys I run with use 15W - 50 but I know that the modern Porsches, including the race cars all run 0W - 40.
I contacted the PCA tech and he said to use what the "manual reccomends" which is anywhere from 5W-30 to 20W-50 dino oil. There is a comment about synthetic oil comming onto the market but that's it.
I understand there is a "slight" performance advantage to going with the lighter oil but would this be worthwhile in an older engine.
BTW, I do use a little oil over the course of a weekend but most Porsches do. I change the oil and filter after every other weekend. Any advise would be most appreciated.
Thanks.
