Everyone's a fargin expert
And opinions are like iceholes, everyone's got one and some are smelly and stinky
In any case, $24 for 5 quarts is a bargin

Just compare the specs of the Old vs.New Mobil 1 and JGDT40
|
Where are the specs for JGDT40? I can't find the ZDDP numbers for example.

I am not all that convinced the above link is something I would trust,
If he is that good of a of an engineer I would of expected a write in a professional organization magazine.
Think I will stick with what is working for me.

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".

No...but it's a start. And they specifically advertise the product as "high zinc". "High" is relative. I'm a science person - I want to see numbers back up a claim.

I'm totally in for cat throwing.
Been using Royal Purple for 5 years now. I like it because it looks the same going in the filler tube as it does coming out the drain pan, keeping the mystery alive. Is it cleaning or not? Who knows!
It never goes on sale at Wally world

have you had an oil analysis? I don't think we've had a member using RP post one in the GD section.
