Oil.., What's in your crankcase?

[JakeHalstrom]

Hello,
"Oil" is always an interesting factor in fuel economy and engine longevity. I am just curious as to what oil other drivers are using. Recommendations, pros/Cons dos /don'ts experiences etc...

Thanks in advance, --Jake

Pennzoil mostly...in the cars, trucks and tractors.

Been using Pennzoil for several years, and got no problems so far.
