    just curious, will it cause engine damage if you will pour engine oil designed for gasoline engine into a diesel engine? i have observed people doing this especially in govt vehicles when oil for diesel engine is not available, they pour gasoline engine oil into diesel vehicles.

    only one thing that i can say, is that they dont know what they are doing,it may hurt the engine and also they put their selves in danger,they dont even think that they create a bomb for themselves.

    a diesel engine has higher compression and higher temperature levels than a gasoline engine, ergo you use a different oil.

    Try replacing one with the other, and voila! you got a busted engine.

    honestly, i read the thread on engine oils and cant really figure it out due to some technical terms. sometimes we use the government issued petron engine oil designed for gasoline engine on our diesel vehicles. i checked the cans and there is 20-40. does this mean this oil cant be used on diesel engines? thanks.

    check the label API claims of the oil first. if it says SF/CD or SG/CD, then you can use it interchangeably. Normally, our vehicles have recommended grades based on our engine, so if it says, SF rating. then we can use any SF rating or above. S stands for Service (gasoline engines) and C for Commercial (diesel engines). The higher the second letter, the better the quality. Of course, if money is a constraint, then just use the lower grade possible for your engine.
