At what RPM?
I don’t think it went over 7k. It was a 555 bbc. The customer was all fired up to test some other oil (I forgot what it was) but the cost to test two oils made him wobble a good bit. A third oil would double the money he already spent.

Just got off the phone with them. They recommended the TR1R 10w30 for both Vixen and Gladys. Summit sells a case of 12 for like 139, which ain't terrible. I may go ahead and do that next payday. He said their PPM of ZDDP was 1800
What's the difference?Well crap…now I need to call them because I looked on their web page and I can’t remember if they using ZDTP rather than ZDDP in that oil.
One is zinc diakyl dithiophosphate. The other is zinc dithiophosphate. IIRC some of the higher end synthetics are using ZDTP rather than ZDDP and for the life of me I can't remember why they were using it.What's the difference?
driven recommended this for my 360. GP-1 10W-30 Synthetic Blend High Performance Oil
I want to say that the Torco oil is Group IV and V base stocks but it looks like it's a group III base oil. Which means you can use it with alcohol based fuels. Group IV and V oils hate alcohol based fuels.
Here's a good explanation that doesn't get too deep into the chemistry.you are speaking another language to me with all that..lol

I just stumbled across this video. And what does he say about zinc??? Watch for yourselves. It exposes the bullshitters on here.

I saw this and thought it would be fun to see how long until it showed up here.

Lake Speed Jr does a really good job dispelling myths and cutting through the BS. One can learn a lot from his videos.LOL and I was the sucker who did it.
I mean, even the dullest of the dull should be able to understand that excess ZDDP causes increased friction which is a power killer.
No one can say they’ve never seen it before. Lake Speed, like him or not is a tribologist so he knows what he’s talking about.
