How Often Should You Change Diesel Oil?

If you own a turbodiesel UTE, chances are you bought it for its raw power. AMSOIL synthetic diesel oils provide the outstanding protection needed to keep your UTE operating at its best. But have you ever wondered how often to change diesel oil?

There’s no “one-size-fits-all” answer. How often you change diesel oil depends on different factors, such as:

Driving conditions – the higher the stress level on your engine, the higher the stress on the oil, and the more often it will need changing.
Ambient conditions – extreme heat and cold take a toll on oil, meaning more frequent changes.
Engine modifications – if you’ve modified the engine to have more torque or power, you’ll need to change oil more often.
Manufacturer recommendations – each engine manufacturer has its own oil-change recommendations, so find that information in your owner’s manual and go from there.

Change Diesel Oil As Little As Possible With Oil Analysis

If your goal is to change diesel oil as little as possible, you can’t beat used oil analysis.

It allows you to see precisely what’s happening inside your engine and how the oil is holding up. The results you get from the lab will tell you whether the oil needs changing, ensuring you don’t drain out good oil.
It’s relatively inexpensive, saves time and money in the long run and, as we show here, easy to do.

If oil analysis isn’t for you, we offer a couple of options.
