Interesting info on the Brad Penn green oil. Does this 'racing oil' carry the longevity additive package normally found in 'road' oils that don't get changed as often as racing oil?

If anyone is really really interested in oil you should go visit "Bob is the oil guy forum"
if we are a bit retentive with our LBCs they are REALLY into oil!
The common opinion there is that EOS is good stuff, Lucas may or may not be any good.
STP is basically a viscosity modifier (makes the oil thicker) but at least the regular STP has a fair amount of Zinc.

Another problem we are having is the oil is probably being changed all the time. When all this broke, diesel oil was the way to go. Now I hear the zinc has been reduced in it but they don't advertise that. I cannot beleive somebody isn't marketing an street oil with zinc for these old tubs. I checked into getting Castrol from the UK (in the one gallon tins)which still has the zinc, but the cost was rediculus even before shipping.

I have read that one of the STP oil treatments is better than the other, but I can't find it in the stores.

I guess the best thing to do is use regular oil and add the GM additive.

70herald, STP is definately more than an oil thickner. There is a definite attraction to the metal [& your hands etc] which stops the oil draining off.

I was using it in a Hewland transaxle [crash box] in a Lotus 20 F2 open wheeler. During a rebuild we discovered that one tooth of the crownwheel had a crack at its base.

While we were waiting for a new crownwheel, & pinion to come from UK, I did one race with it, with STP in the oil. After fitting the new gear, the old stuff was thrown in the long grass, out the back of the shed.

Nine months later a mate with the same box asked me if I had a spare of that ratio, which he could not get in time for a race. I told him about my old one, out in the grass, which I thought would be rusted half away. He thought it was worth a look, & came over.

After 20 minutes ripping the grass out, we found them, half burried in the dirt.
That crownwheel & pinion were perfect. There was not one trace of rust, they were still slightly sticky with oil, & had that STP smell.

As the STP patents have now expired, I believe that some of the newer products are using the same technology.

It's impossible to know from the various conflicting claims, just what an oil contains these days. I suspect that Valvoline is telling lies

Just for clarity, I believe Valvoline is (and always has been) truthful about the content of their oil. Although I can't prove it, I believe they (and all the other US motor oil makers) were told that they "had" to "voluntarily" reduce to at least .12%.

Since this isn't a political forum, I'll leave out my comments about the real bad guys and "taxation without representation".
