$23.88 for Mobil 1 @ Wal-Mart

Mobil 1 0W-40 has been fine for me. It also makes recycling the used oil easier pouring it back into the 5 qt jugs, instead of messing with trying to pour the used oil into all those 1 qt bottles.

You listen Jake Raby? We need the the DT40 in 5 qt jugs!

If we had ZDDP numbers for JGDT40,would we know if it is good/bad ? Tribology is a tough enough subject to master but when you overlay the M96 quirks on the subject it becomes fiendishly complicated to figure out which is best oil based on any data.
It comes down to faith in whoever makes a recommendation. So it is a 1990's Mobil spec that is no longer available vs.JGDT40 Lake Speed/Raby.
This link gives some comparative data for Mobil 1 vs. JGDT40.Just scroll down to the piece on oil.

No offense since you seem like a good guy with good intentions, but these statements made my jaw drop!

I never take a manufacturers word for their product as they are obviously trying to turn a profit. It's not difficult to make the choice to educate yourself on a subject.

Yes, I want the ZDDP numbers for JGDT40 and yes, anyone can choose to understand them.
Personally, I never make an uneducated choice based on "faith".
