Valvoline VR1 Racing Oil...

I think VR1 is okay and it comes in 10W30 and 20W50. It's still fairly inexpensive. I have been running it in the Z since the new cam and gear drive went in and I don't have a problem. If anyone has a definative answer on the amount of ZDDS in VR1 oils I would be interested to hear it.

You are fine with a good quality oil. I like Valvoline and Castrol.

Only affecting flat tappet motors right? Anyway I'm running full synthetic so it shouldn't matter, but diesel oils also lack the detergents to keep the motor clean don't they?

You'll have to ask Jake what regular oil and a Hyd. flat tapet do

Has anyone actually found any supporting info on this article? I only spent a couple freaking hours of my life on this... and I'm done.
I tried to do some searches, and everything went back to about 100 different websites with the same letter from Foreign Parts Positively.
...or websites selling ZDDF additives. Yeah, I'll believe them.
I tried to find a couple of the noted bulletins, and can't find anything... everything goes back to the original letter.

I have absolutely no respect for letters and articles that are poorly dated and reference sources without links, names, phone numbers.
It looks so much like a bad e-mail, I had to check Snopes. (No help there).

The best ZDDP info I found seemed to be at www.mobil1.com, but even they are a little vague. For example:
http://www.mobiloil.com/USA-English/...otor_Oils.aspx
Mobil seems to say that the engine guys say 800ppm is OK, but if you want more ZDDP, we have products for you.
The Mobile1 chart of their oils with Phos levels:
http://www.mobiloil.com/USA-English/...duct_Guide.pdf

What do I believe?
ZDDP is real.
It has been reduced to 800ppm max. (Higher levels are available for non-street car applications.)
When was it reduced? Started reducing in 1988? maybe?
How much is bad for cat convertor? Not clear.
How much is needed for engine lube (either new or old)? Not clear.

I'm not saying it's bull. I'm just saying it smells a little funky.
In the famous words of Cheech and Chong; if it looks like it, feels like it, smells like it, and tastes like it... it probably is...
Goodnight.

You could just ask the 1000's of guys that have lost cam lobes due to this. Me being one.
