Would you use a normal oil (like mobil1 or castrol) in a diesel car? I have heard synthetic is the best way to go.

First of all, lube oil in any engine is used for lubrication and cooling, especially the underside of the pistons. Diesels make lots of heat and are dirty with carbon and exhaust particulates that blow by the piston rings. Thus, diesels require heavier oils with lots of detergents to keep engine parts clean. Plus the combustion pulse of a diesel is more harsh than a gas engine and needs the protection of higher viscosity oils.
Short answer, NO, diesel engines need thicker oil that won't thin out with heat and has lots of detergents.
Stick to the manufacturer's suggestion!

You can use either. Diesel has nothing to do with it. You're dealing with the lubrication of the engine. Synthetic is better if you don't mind the cost, but it's unrelated to whether the engine powers from gasoline or diesel.

yes you can, but it is best to use the type and grade that the manufacturer recommends
