Thread: Oil Change Once a Year?

    I have a Dodge Dakota that gets about 3K miles/year on its 4.7L V8. I use Mobil-1 for it's anti-sludge properties and change the oil once/year.

    At around 200,000 miles, I decided to heck with frequent oil changes. Money saved on that is best put to a new engine or vehicle. Now I have 319,000 miles on it and have never been inside the engine, 1999 F150 5.4L. If it blows up tomorrow, I can't fault it.

    The key is to get the oil hot by driving more than 10 miles in a trip. That boils off the crankcase condensation from shutdown that mixes with the oil making acids. I just top it off.

    I agree with you limiting the money you spend on an older vehicle. You already have the miles on the truck that many vehicles will never reach.

    My brothers friend purchased a low mileage (30,000 or so miles), one owner, 10 year old 1957 Pontiac station wagon. The old woman he purchased it from never changed the oil. She only had the gas station attendant add oil as needed. When we took of the valve covers off, there was so much crud in the engine it was solid and you could barely see the rocker arms.

    Newer cars just do not make sludge like that any more! But I still change oil & filters according to manufacturers recommendation! They know what they are doing and you will not go wrong doing what they recommend!
    You can never go home again.

    My Jeep just turned over 374,000 miles with an oil change @ 4,000 miles. Living in the country I do a minimum of 20 miles per trip, often more.

    In the 50s non-detergent oil was readily available because poured Babbitt bearings were common in engines. Today's lubricants and manufacturing techniques are far superior to those of the last century. Today's vehicles are capable of over 100,000 miles with little maintenance and over 200,000-300,000 miles with normal maintenance.

    To clean the Pontiac we used fuel oil to clean the rocker arms, added a quart of fuel oil, removed the oil filter, let the car idle for a while, and changed to detergent oil with a new filter. The next weekend the oil and filter were changed again. After that the oil and filter were changed when the oil got black. The only noticeable damage was a noisy valve train.

    My 2017 Toyota Tundra guide says to change 0-20 synthetic oil every 10k along with the filter.

    Wife's Mini Cooper gets changed once a year based on time. The computer never calls for a change before that. Full synthetic. Older cars with carb's are different. My collector cars I still change once a year with very few miles just because it makes me feel more comfortable.
