Gas mixture

I heard today someone say that you can raise the cetane rating by adding a couple of gallons of gas to a tank of diesel. Anyone ever hear of this?

I haven't heard of it, but I sure wouldn't do it! If you want to raise cetane, get a good fuel additive.

It`s a sure and fast way to destroy your $expensive$ fuel pump. To many detergents in gasoline, find a good additive.

I heard of truckers that run in the cold winter's here in Minnesota had 1-2 gallons to 100+ gallons to prevent gelling of the fuel. But far as improving the cetane I don't know. I am with the others get a good additive, why chance recking anything. The money saved in long run can be used for bombing :-laf .

Bad idea.

Raise the Cetane?!?!?!? You're being led astray.



Cetane and octane are completely at odds. Higher octane indicates the fuel's ability to reduce knock from "dieseling" in high-compression gassers. Higher cetane numbers indicate the fuel's tendency to combustion under pressure--just what a diesel relies on. Our tanks aren't big enough that the fuel pump can tolerate the reduced lubricity of much more than a squirt of gasoline. A good additive can be found to do whatever it is you're looking for in a gas mix.



I'll second . . . Bad Idea

I agree... octane and cetane are opposites.



Here in Mexico, the truckers DO add gasoline to prevent gelling in cold weather since we do not have winter blend fuels. I would not recommend it... but then they do a lot of things down here that I wouldn't recommend! But, it does work in an emergency!

When we lived in Ellensburg (cold winters) in the early '80s our neighbor always put 2-3 gallons of gas per tankful in his '83 Buick LeSabre diesel as an anti-gel measure. Amazingly he had zero injection pump or engine trouble from the time he bought it new until he sold it in '85 with 145k. This car was totally atypical for GM, it was dead reliable and I really wanted to snatch it up when he sold it.
