I've noticed all over the net that Valvoline Maxlife is everywhere, I've also noticed that most people think high mileage oils are BS. Is Maxlife better or equal to a premium dino oil such as castrol or chevron supreme?
I would be interested in seeing if those two oils had a better additive package than the Valvoline Maxlife but not interested enough to send some in for analysisquote:

Both the GTX HM and Pennzoil HM contain moly, so they'd be decent choices.
For my 3.8L I think this is a good thing - it does reduce oil consumption dramatically and seems to help with high rpm driving. IMO its more of a performance oil than high mileage oil, but thats just my opinionquote:

By the way, one of the main reasons Maxlife slows down oil consumption is because it's thicker than most oils of the same viscosity. For example, most 10w30 oils are in the 10 to 10.5 cst at 100c range. My last two oil analysis results with Maxlife 10w30 showed it at 11.4 to 11.5 cst at 100c. That alone plays a big factor in reducing oil consumption.

Was that regular or full synthetic Maxlife? Because I have the regular down for 10.66 cSt @100C.

Merkava, you do realize the oil's formulation MIGHT change a bit in the 5.5 years since this thread was first posted...right?
