I've been interested in diesel pick ups for a while now, and same across something interesting.

Apparently it can run on motor oil and/or regular unleaded gas?!

Any one try this before ?

 

I've had two diesels. One was a Toronado with GM's 350 diesel. The other, presently owned, is a '97 Dodge with a Cummins diesel.

The Toronado made it to 230k or 240k. We sold it to our son, who loaned it to a friend who filled it with gas instead of diesel. He reported that it made loud noises and quit running. As in, it broke the crank among other internal injuries.

My engine sees only diesel fuel so I can't speak from experience but there are some who put their used oil through their diesels in diluted form. They change their oil then filter the old oil and pour it in the tank along with a full tank of diesel. Watching the forums there is quite a bit of discussion as to the wisdom of doing so. Proponents claim to have been doing it for years with no problems, others claim damage to the engine.

Waste cooking oil can be treated to run diesel engines. Doing so allows one to avoid federal and state taxes on diesel fuel. That has led to some restaruants selling their waste oil and theft of waste cooking oil.

You may be thinking of the military engines which are designed to run on anything - gas, oil. diesel, peanut butter (joking with that one). If any of those have hit the consumer market I haven't heard of it. But then, I am sometimes amazed at what goes on without me knowing about it.

 

I've had several diesel engined vehicles, including my lorry truck with a 12 liter six. Personally I would not risk braking the fuel pump or clogging the injectors to save a few bucks as they can cost up to 500 eur per part, a Vw/Audi BMM pump can be up to 1k. I suppose it COULD work with some older car, I'm told old diesel mercs can run with potato mash if need be (haha joke...) but on more modern vehicles we're talking about thousands of a millimeter in tolerance inside the parts so the risk is a wee bit too big...

 

The multifuel deuce and half is the vehicle your thinking of unless is the m1 abram lol.

I found a couple websites with info on what I'm talking about. Ill post links tomorrow.

This is not the exact post I was looking for but it is on the same site.

 

If that was the case why would they make gas only engines instead of them all being diesels and being able to run on either type of fuel? Answer- diesels cannot run on gas, or motor oil.

 

I think you'll find that there are a few marine engines our there that can run on either or both at the same time, but then we are talking industrial fuel management systems here...
For us land lubbers, diesels really don't like petrol and visa versa. Don't do it!!! Sea foam will not help rectify mistakes of this magnitude.

 

A firend of mine once got diesel from a petrol pistol in a gas station to his Ford Sierra. Result: catastrofic head failure and complete engine overhaul on the petrol company.
