Oil Change interval based on time

Hi everyone. I did a search for oil changes based on time and not mileage and didn't find much so I thought I'd ask.

I'd like to get some opinions on how often to get an oil change based on time. I live in Colorado where it is a bit dryer than other areas of the country. My 2012 Discovery 40G (diesel) is garage kept and over the past couple of years, we haven't gone on many long road trips. We typically dry camp about 75 miles away about 6 times a summer. Beyond that, we take it out once every month or so year round to keep things circulating. My last oil change was in May of 2014 and I've put about 1,000 miles on it over the last two years. With oil changes costing upwards of $250 or more, I thought I'd find out if there are any thoughts on how long is too long to go between oil changes. I'm not looking for 'why not spend the $250 to make sure your $200k investment is safe?'. I just want to know if I'm the only one that thinks they can go longer between oil changes.

Thanks in advance!

  • Oil analysis is the only way to go. You may get ten years life.
  • Check what your engine manufacturer recommends. Cummins, for example, on their later engines has dropped the mileage requirement and just says once a year or every 16,000 miles. Easy to remember.

    Why not spend just a few bucks for an oil analysis? There are many places online where you can send it to get it analyzed or some large truck service centers can handle it for you. Then you will know for sure without anyone making a guess.

    You are looking for a service that includes "TOTAL BASE NUMBER" this tells you how much time your oil has left.

  • We always followed the rule 3 months or 3 thousand miles for our vehicles.

    This response is based on my experience and while some of you on this forum consider it stupid I sure wouldn't want to risk a high price engine over a few bucks.

    Best to follow the engine manufactures recommendations. Not a bunch of us stupid people on forums.
