FAQs

Can too much oil damage a diesel engine?

There is no definitive answer to this question as it depends on the specific engine and also how often it is used. Generally speaking, however, if an engine is used frequently and there is a high level of oil in the system, it can start to suffer from wear and tear. This can lead to decreased performance and eventually failure.

How often should a diesel engine get an oil change?

A diesel engine should get an oil change every 5,000-7,000 miles or every six months on a new engine.

It is normal for an old diesel engine to burn oil. This is because the engine needs oil to run correctly.

Why is diesel oil change so expensive?

Diesel fuel and oil are more expensive to produce because they contain more pollutants than petroleum.

Why does diesel motor oil turn black?

Diesel motor oil turns black because it contains a high level of lead. When your mechanic changes the oil in your car, he is also changing the lead content of the oil. This can cause the oil to turn black and have a bad odor.

Diesel motor oils provide an excellent balance of protection and performance. They are a great choice for those who want the best performance from their vehicle, without sacrificing protection.
