I've always used GM EOS. people have said (on here) that it is better to just use an oil with enough zinc as mixing/matching additives can play havoc with the chemistry but with you have the oil in hand I would not sweat using an additive.

I would sooner buy a proper oil. From what I've read, adding too much zddp can be detrimental to lubrication including cam wear. Ditto. I was told by a lubricant engineer that additives will fall out of suspension and settle in the pan as well. Brad Penn (1500PPM) is used by a large percent of high dollar engine builders, and is cheaper than VR1 (1200PPM).

Any oil with zinc in it, had the zinc additive put in it...
been using the zddp additive for many years...I add the 4 oz bottle into the one gallon jug of oil...shake it....done..

Adding it after the product is finished is different than adding it during the manufacturing process. Why would anyone run an oil they have to buy a $4-$10 addative for, when they could buy an oil that already has it?

I run VR-1 in a mild 440 with stock hydraulic flat tappet - over 20 years - no additives, no problems
Also VR-1 used in my 500HP 408 stroker SB, solid flat tappet - used for the last 4 years - no additives, no problems
I used Brad Penn in the 408 for the first year, but it would use a half quart between changes, switched to VR-1, all is good
Brad Penn always seems a lot thicker than what the viscosity is showing on the label, and seems "stringy" when you pour it in, compared to my other brands

For those of you who use VR1, are you using the synthetic, or conventional?

That's good to know. I also find that BP 5W-30 and 0W-30 requires topping off between oil changes (about 2000 - 2500 miles). Relative evaporation between oils can compared using the volatility test results. Sometimes the NOACK volatility for can be found on spec sheets and almost always the Flash Point. The flash point is obviously a less direct correlation to the evaporation rate but its better than nothing. Volatility can vary between grades as well as between brands. The actual thickness (viscosity) of any oil can be usually found on the manufacture's spec sheet. Richard Widman has an on-line calculator that can be used to show the viscosity at any temperature given viscosity at the two standard temperatures on those sheets. Graph & Table for up to 4 Oils Actual oil viscosity definately varies with the allowable limits of the grade.

My local Autozone has quit carrying 20w50 motor oil My local Autozone did the same. Found out recently when trying to buy some. Bought some today from NAPA, they had it on sale. I like it for some high mileage vehicles I have for the added thickness.
