Diesel engines and gasoline engines may seem similar at a glance, but under the hood, they operate very differently. Because of this, the maintenance routines for diesel-powered vehicles vary quite a bit from those of gas-powered cars. If you drive a diesel truck or car, understanding these differences can help you keep your engine running longer, more efficiently, and with fewer surprises down the road. Regular maintenance is crucial for both types of engines, but the approach and timing can vary in ways that are important to know. How Diesel Engines Work Differently The core function of both diesel and gas engines is to convert fuel into energy through combustion. However, gasoline engines rely on spark plugs to ignite a fuel-air mixture, while diesel engines use compression alone to ignite diesel fuel. This difference in combustion affects everything from fuel efficiency and power output to maintenance schedules and potential repairs. Diesel engines are known fo ... read more
