I run prro blend in my tow rig as well as my drag truck. I like the product. I also ran it in my 96 with a rear diff temp gauge. I seem to recall a 20 degree drop under a hard pull.
The oil cooling products cool the oil about 30 degrees on a big prostreet GSXR oil cooled motor on the street. With a oil temp gauge in the pan, and the tire stuff is the cats ass.
