Ive had DOT check the diesel in the tank on the delivery truck I drive for work during one of their truck checks.
next tank i will try b20 from john ray and sons, they have b5 aswell.
swap a 6 speed in mine
I didnt personally do the swap in my car. A little too involved for me and I dont have the place or time.
True that, wayy to involved
stanadyne is the best additive you can get for a diesel, bio will start clouding at a higher temp then any other diesel/#2
D&W diesel is the best place to go for anything diesel related (they even have some big turbo related stuff)
