AMSOIL Performance Turns Customer into Dealer
AMSOIL product performance is often the tipping point for customers to become Dealers.

Such is the case with Dealer Julian Dhanani of La Jolla, Calif. “I started using AMSOIL products several years ago when I began modifying the 2006 Honda* Civic Si* I had at the time,” Dhanani said.

Dhanani modified the Honda so he could run it on open track days at the Streets of Willow course in Rosamond, Calif., a 1.6-mile street track. He upgraded the camshafts in the car to use on the track.
