Therein lies the first major difference between the oils. Diesel engine oils have a higher anti-wear (AW) load in the form of zinc dialkyldithiophosphate (ZDDP). The catalytic converters in diesel systems are designed to be able to deal with this problem, while the gasoline systems are not.
Sure. You can use it for lubrication or you can even mix it with diesel and use it for fuel. Diesel oil for lubrication is NOT the same formula used in oil for gas engine. Diesel rated oil has soot control properties among other things and is usually of a heavier weight.
Beside above, is diesel oil darker than regular oil? It is normal for diesel motor oil to turn black quickly. The dark color is a sign that the oil is performing correctly by keeping byproducts of the combustion process in suspension.

Is synthetic oil better in diesel engines?
There are many advantages to using synthetic engine oil in your diesel engine. Synthetics have a much better flow rate in cold weather than conventional engine oils, allowing critical moving parts to be better lubricated on start up.
Is synthetic oil bad for diesel engines?
The Top 5 Synthetic Oils for Diesel Engines The traditional is usually cheaper but will not do as good a job of lubricating the components of the engine. You also need to change the oil more frequently too. Synthetic oils are more expensive but will lubricate the components a lot longer.
Do you need special oil for diesel engines?
Diesel engines need a high viscosity oil or a synthetic oil . Since these engines combust at much higher compression ratio than gasoline engines, the oil used in the motor has to be able to withstand tremendous forces, usually of 40,000 to 50,000 psi.
What happens if you put the wrong oil in a diesel engine?
Motor oil slip-ups. The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. Use only what the owner’s manual specifies. Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.
Is there special oil for diesel engines?
Just like regular gasoline engines, diesel engines require regular maintenance that involves changing the lubricating oil that keeps your vehicle’s parts running smoothly. This job requires lubricating oil that’s specially designed for diesel engines — not gasoline engines.
What is 15w40 oil used for?

Mobil Gas Engine Oil 15W-40 is formulated from high quality base stocks and a balanced additive system.
Why do diesels take so much oil?
Diesels use large volumes of oil for cooling and for contaminate handling. This allows the oil change intervals to be longer than on a gasser. You have to remember that the emissions “stuff” is after the combustion chamber. This means there are still contaminates getting into the oil.
How often do you change your oil in a diesel?
Oil Change Intervals for Diesel Engines Most diesel engines should have their oil changed about every 3,000 miles if you’re using standard oil and every 5,000 to 6,000 miles if you’re using full synthetic oil.
Can I use 15w40 instead of 5w30?
First, the oil viscosity change won’t cause your head gaskets to blow off. The real problem with using 15w40 in place of 5w30 is the increase thickness of 15w40. Obviously the heavier oil would be a good thing.
Is Rotella 15w40 synthetic?
