The Role of Oil Changes in Vehicle Maintenance

Engine oil is the lifeblood of your vehicle. It lubricates moving parts, reduces friction, carries away heat and keeps the engine clean. Over time, it degrades and becomes contaminated - and that's when problems start.

How often should you change your oil? Most modern vehicles need an oil change every 10,000–15,000 miles or once a year, whichever comes first. Some manufacturers specify longer intervals, but for a diesel engine - especially one used for lots of short journeys - more frequent changes are better.

What happens if you don't? Old oil loses its viscosity and ability to lubricate properly. Sludge builds up in the engine, oil passages become blocked and wear accelerates. The end result can be expensive engine damage that a regular oil change would have prevented.

Which oil should you use? Always use the grade specified in your owner's manual or recommended by your garage. Using the wrong grade - especially in modern diesels with DPF systems - can cause serious problems.

At Diesel Vehicle Services, every full service includes an oil and filter change using the correct grade for your vehicle. If you're not sure when your oil was last changed, bring it in and we'll check it as part of a free visual inspection.
