I have been a Penzoil user for over 20yrs.10w30 in the winter and 10w40 in the summer.I was a Fram oil filter user for about the same amount of time until I read a link here awhile back where the review was really bad about them.I changed to WEX filters and saw a noticeable difference in oil pressure.I do feel there are a much better filter.

I use vegitable oil in the van I find that the nice light oil really help reduce the internal friction in the engine thus giving way better throttle response and better mileage.

Honestly I have been running either 10w30 or 10w40. Synthetic oil will not harm your engine from being thinner provided you buy the same weight oil. The synthetic oil is better because it lasts longer and can handle more heat and higher pressures before it starts to break down.

I have been running synthetic oil in my 2stroke dirt bike since 92 with the oil mixed at 100:1. In my street bike I run Royal purple full synthetic 20w50 and have been very happy with it.

LMAO, now that was funny!
I've run 10W30, when it was new, and later 10W40, and now 20W50 in my jeep, with fram filters most of the way, (till I read that dang internet page Gary wrote about) over 180,000 miles on it now. No signs of the engine giving up. Granted, the I6 engines in the jeeps were work horses. Chrysler had a brain fart and decided they were lasting too long, so they discontinued them. Frankly, I'd like to have one in my 'stro along with the AW4 transmission that came with it. About 220HP and a trans that shifts seamlessly. Hmmm, might have to take some measurements....
