Oil Change Once a Year?

[gwp]

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!

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.

I was in Lowes looking at trimmers and they have a wheel type trimmer with a Briggs engine and they advertise never change the oil again just check and add.

My 2017 Jeep bought last Oct just passed 5k miles, My computer says there is 42% oil life remaining, I will change when the computer says to.

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.

I took a closer look at the Mobil 1 container. It said this annual oil is good for one year or 20k miles whichever comes first.
