I do not add anything and run 0W40 full synthetic year round.

 

Thanks. that was a good website to look at. it helped me alot i dont think im going to add it to my truck if it adds all that air in it. Thanks agin for the help.

 

I sent that link to an engineer friend who is into drag racing and he said that air in oil is one of the worst things that can happen. Apparently, when bubbles pop (as will happen with aerated oil) between gears and bearing surfaces, there is a tremendous amount of energy released and that can damage the gear face or race of a bearing.

 

I've never been a big fan of additives but that's just me. My trucks have all run fine, even with the beating that I have given them.
