Put in a 383 stroker in my 97 Silverado during the summer, and started its life on mobil 5w-30 (non synthetic) oil. I am very new to this board, and do not know a whole lot about oil. Sooo
1.) Was the Mobil 5w-30 a decent break in engine oil, or was it a bad one?
2.) I 've just switched over to synthetic oil and..... (upon hearing rave reviews from this board, and awesome oil analysis) put in the German Castrol Syntec 0w-30 with K&N oil filter today. The Mobil 5w-30 is going to Blackstone Labs. for analysis to get checked out.
So what do you guys think of what I've done? Good or Bad? I heard of this board through LS1tech.com and am very excited to learn more about the life-blood of our engines!!!!!
