Ask Professor Diesel – 05/26/2014

 

This week’s question comes from John in the USA:

 

Professor Diesel:

I know that diesel engines can run on many types of fuel, what would happen if I try and use gasoline?

 

Answer:

NEVER use gasoline in a diesel engine. At best, permanent damage will result. At worst, explosion or fire. Some diesel operators will add a little gasoline to diesel when preparing for storage over extended periods, as this can help in starting (MarineDiesel does not recommend this practice and it will void your warranty if you try it). NEVER more than 10% of total volume. The engine will run, but it is safest to drain the fuel and lines if gasoline has been added.
