I run 10-W40 Valvoline in the engine- can't seem to justify the cost of Synth motor oil when I'm gonna change it ever 2500 miles anyway.

I finally switched over to synthetic's for the gear boxes. I have always had heat problems in the summer months w/ my dual t'case setup. Going to Valvoline Synth 90-W140 made a very noticable change in temps. I also run synth in the rear diff- spinning 5.29's down the hwy generates a lot of heat too.....

"Nine-11 changed me," he said. "I'm shocked that it didn't change the whole country, frankly."
