DIESEL SERVICE

Remember, proper diesel engine maintenance is important to preserve the life of your vehicle. Check your owner’s manual to determine maintenance schedules.

Diesel Maintenance, Key to Fewer Repairs

Your light-duty diesel engine is very different from a gas engine starting with the way it gains power using compression in the combustion chamber to ignite the fuel versus a spark like a gas engine. The real key to keeping that diesel engine in top shape is filters and with regularly scheduled maintenance and fluids - specifically diesel engine oil, exhaust treatment fluid, power steering fluid, coolant, brake fluid, automatic transmission fluid, rear differential fluid. On 4×4’s, you also have transfer case fluid and front differential fluid. It is more than you need on a gas engine but the durability and power you get with diesel are worth it and the routine maintenance will save you thousands of dollars in repairs easily.

Our diesel techs also realize that light-duty trucks are not all alike, thus keeping them at peak performance requires flexibility.

Some of our drivers are typical and can stay within the standard "suggested" maintenance and others are a bit harder on their vehicles based on the jobs they use them for or the way they "play" in them maybe while off-roading using the 4x4 features. Either way, we can schedule their maintenance around those needs and make sure repairs are done when it is convenient and avoided where possible!
