Gasoline Engine

Is working on a diesel engine more difficult than on a gasoline engine?

I am referring to small engines like those that might be seen in a VW Jetta or a Mercedes passenger car. NOT on trucks or big rigs.

It's all parts bolted together, basically. You'd probably find some things about certain gas engines that are a pain in the butt, and the same for diesels.

is a desiel oil change the same as a gasoline engine oil change?

How different is it to change the oil of a desiel engine versus a gasoline engine? Also what weight oil should I use? And oil filter?

The oil change process is nearly identical between the two engines. It is best to prime the oil filter prior to installing on the vehicle, this also goes to gasoline engines (some designs do not allow this due to filter position).

As for oil and filter... follow the owners manual. Generally, most diesels use 15w40 oil, brand name filters are recommended.

A second option is to use synthetic diesel oil. It is about twice the cost, but you can double your oil change interval. If you stick to the OEM recommended interval... don't waste your money on synthetic fluids.

The last thing that no one yet mentioned... It is highly recommended you change you fuel filter on every oil change. Your fuel filter is just-as or more important then the engine oil change in a diesel motor. The fuel filter protects all your injection pump and injector components. DO NOT OVERLOOK THE FUEL FILTER, or you will have costly repairs.
Changing the fuel filter (depending on vehicle and engine setup) is usually a easier then the oil change. Simply spin off the filter, prime the new filter and reinstall. This again will be in your owners manual.
