What is Your Oil Change Interval?

 When I was working I would typically drive about 3000 miles per month. I would change the oil in my truck every two months or about 6 thousand miles, conventional oil. Now I might drive 3000 miles a year, so I change it at 3000 miles, synthetic oil. What do you guys do?

  1. The same mileage with my 2000 GMC pick-up. High mileage oil but not synthetic. Some claim modern oils will last longer, but oil is blood to an engine. I don't mind the extra effort to keep it clean. I still work, but no long range commutes. I average about 3 changes a year.

  2. Every 5K. Everywhere I've had oil changed in the last ten years; dealers, quick change franchises, independents, they all do the same thing. They sell synthetic oil at twice the cost and justify the expense by claiming synthetic lasts twice as long. Then they put a sticker on the windshield reminding me to have oil changed in 3,000 miles. Every damned one of them does it.

  3. The Subaru outback XT gets 7000 miles changes, or 1 year. 0w-20 synthetic.

    The Dodge Ram diesel 6.7 gets the filter changed every 5000 miles (with the appropriate top up of oil) and then changed every year. (which, so far, has worked out to a change every 9-10 months)...15W-40 also full synthetic.

    If you are not using synthetic in your engines, you are being foolish, the significantly lower friction coefficient make for almost zero wear and the cling factor prevents corrosion.
    Stop listening to folks who just repeat old-wives-tales about synthetics and oils in general. Just because someone says it doesn't make it true....do the research and find out the truth. Some guy who has no engineering knowledge repeating what his bar friends heard from 40 years ago likely isn't giving you good advice.
    Don't listen to me either: learn something new..... Oil technology has changed since the 1930's

  4. I do 4000 miles, synthetic oil. The owners' manuals and the oil bottles all say I can go MUCH longer. Thing is, neither the car manufacturer nor the oil manufacturer are paying my repair bills or replacement costs, and I tend to drive my vehicles until they rot out from under me!

  6. Don't drive a lot so the vehicles all get an oil change annually...

  8. Bought a '99 Dodge Ram with 150K on the 5.2l V-8 that looks like that except everything was BBQ'd almost dry.

    Keeps me on my toes waiting for the oil pickup to plug and kill oil pressure, and there is a shiny glitter in the oil for some reason...
