Alternative thoughts on HPL **UPDATED**

Used 6oz in 6qts in the crank case. Gumout 510011 Multi-System Tune-Up. Mechanic in a can.

Gotcha. I like their Regane fuel additive a lot

I use an ounce per qt in the crank case of this for about 100 miles prior to an oil change when I want a quick clean up.

I toss around four ounces in the crankcase and the rest in the tank the night before with a gallon of premium non ethanol. Works well on 1/3 tank. Drive it on highway and shutoff hot. Drive to dealership, get there early, pop the hood and toss it in and idle for five to ten minutes.
