what is the difference in diesel oil and reg. motor oil? could I use diesel oil in my non diesel car?if no why

Answer 1

Wallysrusty, Diesel engine oil has a very large amount of additives to remove sulfur, a product of combustion in a diesel engine. Generally speaking diesel crankcase oils have viscosity ratings of 15w-40 & 20w-50. These viscosity ratings are much too high for a modern gasoline engine. Consult your handbook in your glove compartment for the corect viscosity for your car. Newer cars call for 5w-30 or in Fords case 5w20. The use of the higher viscocity 15w40 diesel oil would not cool your engine as well as lower correct viscoty oils. As viscosity's go up the internal drag on the oil pump and all moving parts severly reduce horsepower.

Jole's somewhat off base on the heat of combustion in a diesel engine. First of all diesel fuel fires by the heat of compression in a diesel engine. This heat is much lower than the heat of combustion in any gasoline engine. There are heat charts avalible on line of the flash points of all fuels if your intrested.

Answer 2

If you're talking about motor oil for diesel engines, don't use it in your gasoline engine. It may not do any harm right away, but it's not intended for the gas engine.
Clearances in a gas engine are usually very tight and require an oil that will flow into those tight spaces easily. Oil intended for gas engines is milti-viscosity (i.e. 5w-30 or 10w-30). This means the oil flows easily (like a 5 weight oil) when cold, but resists pressure like a heavier oil (30 weight) when heated up. Diesel engines have looser clearances and generally require a heavier oil, often single viscosity (30w). Also, the diesel engine oil has more polymers and detergent additives that allow it carry more combustion residue (soot) in suspension for a longer period before being changed. If you took contaminated oil from a diesel engine and put it in the gas engine, it would plug things up and turn to sludge rather quickly.

Use ONLY the type and grade of oil your owners manual recommends.

Answer 3

What Is Diesel Oil

Answer 4

something of the solutions so a techniques are completely incorrect. Motor oil will be mixed with diesel gasoline yet i do not recommend it because the oil that you get rid of from the engine has all sorts of impurities in it. I.E. metallic, soot, benzine , water, . Used motor oil is presently filtered and utilized in different products. without the impurities bumped off they could clog the filters, tarnish or harm the injectors and pumps. Its in basic terms no longer nicely worth it threat of the wear and tear except you've an previous oil burner furnace to burn it in to warmth your storage or domicile. instantly Motor oil has to intense a flash element to be use as a flamable engine gasoline via layout. It has factors in it to keep it from vaporizing that may make it so thick it would not lubricate wisely. I.E Grease Now in case you've been to operate a preheater like a grease burner engine, thats yet another tale

Answer 5

Diesel oil has much more detergent in it. It would be ok to use a quart with your other oil. If you car has a high mileage engine I would not use it, it might open up some leaks. If your engine is low mileage I don't see any problems.

Answer 6

deisle fule is the same thing as home heating oil, and has much less lubricating ability than motor oil so definatly a no-no in the engine oil

diesle fuel is ignited at a much higher temp than gasoline, which is accomplished in a diesle engine bu compressing it so tight that it explodes... in gas engines a spark is hot enough to ignight gass completely but wont ignight diesle fuel.

Answer 7

NO - Don't put it in your car.

I don't know why you can't but don't!
In HS my best friend did it right after she got her license/car. She blew her engine!
