Diesel Truck Oil Changes & Maintenance

Maintaining your diesel

So, you just purchased a new diesel truck! What maintenance is required to keep your diesel running reliably? Luckily, the best plan of action is written down in one place. The manufacturer’s maintenance schedule found in your glove box. Here we give you some of the highlights.

Today’s types of diesel are more complex than ever. The demands of modern emissions standards, increased horsepower, torque, and the technology required to keep them running optimally, the maintenance required has increased and is very important. Filters and critical fluids must be in good condition and at adequate levels.

Schedule your diesel truck oil changes!

Regular maintenance of the fluids and filters may seem expensive, but in the end, abiding by the schedule from the manufacturer and keeping up with this routine diesel truck maintenance can save you thousands of dollars in costly repairs. You should schedule your oil every 7500 miles or every 700 hours of operation. This is an industry standard since many types of diesel (think work trucks or ambulances) often sit and idle while someone is working. Just because these bigger vehicles hold, more oil does not mean they can go longer between oil changes.  (This is just a suggestion.  You may need to change your oil sooner!  Make sure to periodically check your oil to see the quality and if it needs to be changed sooner.)

In addition, changing the engine oil more frequently is good for all the seals inside the engine, as they are costly to replace once they begin to leak. Fresh oil changes help to keep seals soft and pliable and doing what they are intended to do. Oil that hasn’t been changed on time and becomes abrasive and can damage moving parts inside the engine.

Fuel filters and injectors

Changing the fuel filters on a diesel is one major service that is overlooked. It is critical that the fuel going to the injectors is clean and has no water or contaminants in it. One injector can cost anywhere from $200-800 since each diesel can have from four to eight injectors. Injectors are very difficult to access to the labor involved can be expensive.

Frequently changing your oil can have a significant impact on the life of the injectors. Old, broken down oil can destroy the injector or cause them to stick and not run optimally. There are also fuel/water separators on diesel engines and some of them can be drained, but it just depends on the make and model.

Since there are many considerations when doing routine maintenance on diesel, it is essential to have an experienced diesel technician you can talk to and that you trust. The mechanics at Britton’s will help you stay up to date on your diesel truck maintenance!
