Anti-gel trick is it true?

I don't know about that. I have used kerosene to thin the mix for my backhoe when I had the cemeteries. But on these new motors I have no clue.

 

I have known several who have done this but in a greater ratio (1 gallon of gas per 20 gallons of diesel). With the cost of gas now days compared to commercial anti-gels this would seem somewhat silly to do. I am not aware of any immediate problems associated with them doing this but at the same time I am not certain whether long term problems (Injectors, injector pumps etc.) could be identified as being because of this act.

On the other hand though from a strictly chemical perspective, it probably isn't a good idea. Adding gas to diesel lowers the lubricity of the diesel as well as the cetane number (Cetane is the inverse of octane) and is what allows diesel to ignite under pressure. Adding a substance with a high octane (Gasoline) to diesel fuel actually ####### the ability of diesel to ignite (Kinda the opposite of what one would expect) and at the same time gasoline raises the combustion temperature and decreases the lubrication which may cause certain wastes to cook in to the injectors. Then there are the emission issues.

My bottom line is that the ratio you mention (1/100) likely would cause little if any problems and also likely it will be of little benefit. Higher ratios "could" cause problems and would be cost prohibitive as compared to commercial anti-gels. Therefore I do not believe it's a good idea.

 

Depending on what truck you have... watch what you burn in the tank. The DPF doesn't like certain things going through the fuel.

 

newer trucks will not like this, ESP ones with DEF injection. Gas is much more corrosive, and will eat newer injector cups, which seal the inj to the head, causing it to suck air when intake is occuring. This will result in a stall if it is a large enough amount.
