Thanks, Andy! and keep us posted. I'm obsessive-compulsive about motor oil, gear oil, grease, and even spray lube for that matter. I have used Valvoline for years now, having switched from Castrol after 2 engine failures. (1 oil pump,1 ****** bearing) I realise all engines will wear out, but I did expect more than 114,000 mi. before pump failure.(ford motor co. had "repaired" under warranty @ 20,000 mi.) The ****** bearing went @ 171,000 in GM V6, to be expected. Prior to Castrol I used Kendall, but it is no longer available in our area. I once drove a V8 Dodge 318 28 mi. w/oil pump drive shaft broken, got a little lifter noise, thought gage wasn't working. Replaced shaft, drove another 140,000 mi. then sold it. That was w/ Kendall oil, havn't tried it w/ other brands. Thank You, LRW.
