Zinc & Phosphorus -- Brad Penn Oil

[patrickt]

Got an email from a Joe Gibbs oil aficionado. He pointed out to me that Joe Gibbs racing oil touts itself as being full compatible between the different flavors of itself. Even gave me this link: http://www.joegibbsracingoil.com/tra...or-Which-15946

XP1, XP2, XP3, XP6, and XP0 are based on the same lubricant technology and are completely compatible. Please download our blending chart for blending specifications.

Brad Penn probably takes the same position.

I guess I need a better definition of compatibility. I take it to mean they will not adversely affect one another, not that they combine to form one together. Hopefully a lubeoligist will chime in. I have always wanted to do what you are doing but was always informed not too. Our local Mobil Rep suggest against it for the reason I gave earlier, you will have two different compatible oils instead of one homogeneous oil.

I am referring to generic over the counter oils availabe at autozone, i have no idea about brad penn oils.

Ol' Joe is even kind of enough to provide you with a downloadable PowerPoint slide presentation showing you the exact effect on viscosity by combining different ounces of different oils with one another. Take a look at this and see if it helps: http://www.joegibbsracingoil.com/Dow...BlendChart.ppt

Thanks, they obviously know more than I do. I do not understand how they combine polymers strands of different lenghts to create an average length. It must take place in the heat of the motor but if that were the case multi-viscosity oil would be toast after the first heat cycle. Interesting information.

Either that or they figure you're just gonna rebuild your engine after the next race anyway.
