Hi - was watching an infomercial where people were racing a car with no oil in it and doing other "no oil" experiments. !
If you beleive that they actually ran an engine with no oil in it, i have some great tune up in a bottle that i'll sell you.
I know that they say there is no oil in it, and they try to show that there is no oil in it, but really, come on. I will bet that the infomercial was shot in segments and then put together so that it looks like the engine is running for extended periods of time. I also wouldn't doubt that there was an external dry sump oil source hooked up. drag cars use dry sump oil setups which means that there is no oil in the oil pan. the oil is stored in a tank outside of the engine, and an external pump, pumps the oil through the engine. the oil then drains into the oil pan, and it is sucked back out to the external tank. if you were to pull the oil pan off of a real race car, there would be very little oil in it.
an engine with no oil in it, with just an additive as protection, would heat up really fast and probably seize after a few minutes of running.
I don't care how good they claim an additive to be, an engine will just not last without oil in it. sure, an engine will run with no oil in it, but not for very long.
the heat from the friction would kill the bearings, rings, cam, lifters and rocker arms. the additive may provide lubrication, but without it being cycled through the engine, and back into the oil pan, there is no way that it can cool off.
the heat would end up cooking the additive off of the parts.
how many times have you heard of someone actually driving their car with absolutly 0 oil in it? besides that, cars these days have oil level sensors and if the oil gets below a certain level, it shuts the engine down.
on an older engine, sure it will still run with 0 oil in it, but i personally have never seen or heard of anyone doing that. even if you pull a dipstick out of an engine and it reads that there is no oil in it, there will still be some oil in the pan and probably enough to be sucked up by the oil pump. however, that amount may not be enough to fully circulate through the entire engine. heat is the enemy of engines, and oils.
I don't beleive in these things, and i think these things are targeted at those people who either are too lazy to check their engine oil, or, that don't know how. they figure that if they put this stuff in their engine, they won't have to worry about the oil level because "on t.v. the engine ran for a long time with no oil at all".
I think it's all a scam myself, and i would never buy any of that stuff.
