I have been a BITOG member for years and the similarities between discussions of oil and discussions here of wax generally go pretty much the same way. My point is that I trust my years of used oil analysis on Mobil 1 to tell me that it is performing as advertised vs speculation that Mobil is lying about the contents of its oil. My latest UOA was on Mobil 1 EP 5W-30 at 7500 miles. I still had a TBN of 3.0 which in my experience tells me I could have easily gotten to 10K without any troubles and adequate anti-wear additives left over. Fact is though I don't trust the oil filter to go that long which is the only reason I generally change at 7500.

I will be doing another UOA next month on the oil currently in the Mustang which is Mobil 1 Racing 0W-30 (unfortunately discontinued). I will post my results then if you are interested...

Fact is if you are doing 3K-5K oil changes ALL of this discussion isn't worth @#$@# because any cheap conventional oil WalMart happens to have on sale will go to 5K easily.

I have to run, gotta pick up my new Crack... oops I mean Blackberry from Sprint and get my son's paintball tanks filled. Be back later....
