A search will find you a huge discussion on the zinc content, or lack of, in modern gasoline engine oils.

Some swear by diesel oil but I am waiting for more data before I test it out on my car.

I think I'm switching to Royal Purple...

I'll keep on using the oil that I have been, in track and street, that kept race car bearings like this for almost 4 years before the rod that you see gave way.

Which is?

Holy $hit Batman!

Just saving you some time.
BTW: I also use it. Can get it in a local store without a loan and it keeps good oil preasure under high temps.

I actually wasn't going to mention it. In all seriousness, most of the people here are intelligent and need to make their own decision. I hated the last thread that got into all the shear properties, engineering links - which anyone can google - and I hate flame $hit between members who have internet and great distance between them.

I use Shell Rotella T 15w-40. It makes me feel all warm and fuzzy.

Personally my favorite is valvoline and that's what I've always used. I'm sick of people telling me that mobil 1 is the best. Recently though I've been trying out castrol. Nothing wrong with it but I think I'll be switching to amsoil soon. But if I have to buy oil at kragen it will be valvoline.

Now let's talk about something less controversial and opinionated, like politics or religion.

heard good things about brad penn grade 1 oil and the price is pretty good so that is what I have in the car now.

Valvoline VR1 20W50 is what I had in the car before the penn

VR1 is an excellent choice. IMHO
We use 25w/60 for track.

I get mine at Autozone, under $40 a case.

Me too Dan. Seriously, this is good stuff.
