I've heard of people putting gas in their tanks when using some other lubricants like used motor oil of WVO. I put about 2-3 gallons of used motor oil in a fill up when I have it, can I also put 3 gallons of gas in there also?? I'm a little to protective of my engine to just try it. And I'm bored at work so I'm just thinkin bout it. yall take it easy

 

Gasoline & Diesel Engines usually don't play well together.

 

What type of used motor oil are you using? Is it the motor oil from your own truck? How does it run with that? I'm using 2 stoke in mine. I'm with Shovel on the gasoline in a diesel, the implacations could be berry, berry bad...

 

When I do blending WVO/WMO I add about 5% RUG (Regular Unleaded Gasoline) to the mix to thin things out. From what I've read, I would want to go to much more. But that will all depend on how think WVO/WMO is.

 

I run used oil from my truck and other friends vehicles. I only get it from close friends cause I know it strictly oil.
