Diesel Oil Changes

Most gas-powered engines need to have the oil changed every 3,000 miles. For diesel engines, the time between diesel oil changes is usually a bit longer. The amount or frequency of oil changes you need will depend on several factors, including your driving habits, your location’s climate, and of course, how you use your vehicle. If you tow heavy loads or a trailer, you’ll likely need a diesel oil change more often. From a Chevrolet Duramax to the Dodge Cummins and Ford Power Stroke, we have the perfect oil for your specific diesel vehicle. When in doubt, refer to your owner’s manual for a recommended diesel oil change schedule.

Diesel Repair

Diesel-powered vehicles have their own set of special challenges, and we can handle anything that comes our way. Since diesel produces more smoke than traditional vehicles, it’s important to keep a close eye on your exhaust system. From a faulty fuel injector or injector pump to a damaged EGR valve or turbocharger, we can resolve the issue for a cleaner, smoother driving experience. Another common repair for diesel vehicles is when the engine experiences a delayed start. It could be a matter of low compression or the fuel delivery system needs an inspection. We’re your Chevrolet, Dodge, and Ford diesel specialists, so bring your vehicle to us and we’ll take a closer look.

A lack of power may occur when you run into trouble starting the vehicle or accelerating. Often, it’s a matter of a dirty fuel filter, issues with the fuel injection, or loose throttle linkage. Another significant difference between diesel engines and standard engines is the use of glow plugs. Traditional cars use spark plugs, but diesel engines rely on glow plugs to ignite the mixture using a heating element. If your glow plugs go bad, you won’t be able to start your engine. We have the tools and the skills to get those glow plugs replaced so you can get back on the road.
