can i put a mix of oil and gas into my gas-powered car?

[niacat the terrible]

title says it, i found a good amount of oil and gas mixed together, and i want to put it into my car but i dont know if its safe or not, can someone pelase tell me?

I think it's like 85-90% gas, for it to work, but it also depends on the engine, and also performance drops when there's a mixed fuel
Ladas can run on that with little to no impact to performance, while the Skoda and Dacia have a moderate performance impact
the Bike and Trabant need a gas-oil mixture to work, and the Volkswagen engines have a severe performance impact, meanwhile the Plymouth V8, I'm not sure.
The Bus and Truck have a performance impact between that of the Ladas and the Skoda & Dacia.

You can but try to keep it as low as possible. When I found my fury yesterday it had 90% water 10% fuel in the tank. I put all the gas I had in it and got it to 80% fuel and 20% water and was able to get it to run and continue on. Car also had 100% diesel fuel in the oil but was just under half full. I drove it probably 80km like this till I found a oil drum and I drained the oil and refilled with straight oil.

I tested the Plymouth with a mixed fuel setting, around 25% oil and 75% gas.....Car was going at around 90 mph, some time after that the oil % in the gas tank dropped below 20 and the car was starting to get a speed boost, but still only 100 mph.

Just keep tipping, once the engine cuts out stop filling, it WILL start again. You just need to push the throttle and not let it idle, else will cut out again. Car will just be slower.

Once you find more gas you can top it up so the car will idle again and will go faster.

Honestly don't fear putting anything in the tank, just wait for it to cut out and you know the limit. Keep adding after that and you will have problems. Its quite linear.

It's just not worth the reduced performance. You won't make it up the hills on mixed fuel.
If you have to do it, the best thing is to keep as much of your gas unmixed as possible. If you have to drain the tank, you can do that with a hose easily. If you have at least 3l of 100% gas, its best to drain it completely, and just rely on 3l to get you far enough to have 2 or 3 buildings to search for more fuel.

Otherwise, drain out most of the mix, add gas to make it run, then when you find 100% gas? DONT put it in the tank. Keep it in a separate jerry can. Then keep struggling on with your litre or two of nasty gas. Once you have a reasonable amount of 100% gas, or you hit a hill, just drain the last little bit of crap out, and refill with the pure stuff.

If you have say, 10l of fuel, at 10% oil, then you need 9l of gas to get that down to 5%, and 90 litres to dilute it all the way to 1%. To get it down to 0? technically an infinite amount.
So if you keep throwing good after bad, it will dog you for a long, long time.
But if we drain that down to just 1l, then we can get down to 5% by adding just a litre of 100% gas. That gives us 2 litres of usable fuel, enough to get to the next stop, or maybe next 2 or 3 stops. That should give us a couple of litres of 100% gas. Keep it rather than adding it to the tank, and burn off the nasty stuff till its all gone, then refuel with the good stuff.

Lets say you are driving a trabby, and you want 3% oil anyway, and you find 50l of fuel which is 30% oil, 70% gas. Sounds like a victory? well not really. You need another 465l of 100% gas to get that to an ideal mixture. So most of that drum will go to waste no matter what. You can use a little, adding it when you would normally add oil. Need 0.1l of oil? that mix will give you 0.2l of gas with it. That is a very, very slow way of using it up, and its not worth hauling it all around for the next... 12,500 km or so? (based on 4l per 100km)

yep thats what I wanted to do with my fury when I found it drain the water and fuel out and put fresh straight fuel. But went to the trunk of my starter car and my syphon hose was missing so I had no way of draining anything so I just dumped all the fuel I had and hoped it was low enough water percentage to get it mobile. After 160 km in the Fury I am down to 2% water with a full tank.
