Do I Really Have To Change My Oil Every Year?

Dear MOby,

I just saw your answer regards oil change. My manual says that I need to change oil every 3000 miles. But I only ride about 1000 miles per year (very short commute). By the book, I need to perform oil change every three years. Do I really need to change oil every year? Is it okay to change oil every three years, just because I don’t ride that much?

Thank you

PS: Just to make myself comfortable, I do oil change once a year.

If you only get 1000 miles a year in, I'd be changing the oil even more then once a year. At the VERY LEAST once a year at the beginning of riding season.

They say leaving it in for over a year is not good because of the acids that build up in the oil over time. I'm not sure with the fully synthetic oils if that changed. That acid thing come out of the 70's the first time I would hear that.

Conventional wisdom says yes. once per year. Our two GM cars with oil minders require once per year per the owner's manual even if the minder does not go down to 0%. I ride my Harley Sportster and my Suzuki less than 1000 miles per year each and have changed the oil every two years for several years but I always run them at least 15 miles each ride. I sometimes give them only a new filter with a bit of fresh oil to top them off. No problem so far and the bikes burn no oil and run very well. I will not do that to my Triumph. Old bikes can be disposable but my Triumph is not there yet. Three or four quarts of oil and a new filter once per year are not a budget buster if you DIY.

I'd change it every season whether I rode 20 miles on the bike, or 3,000 miles. And, I actually change the oil on my air-cooled bikes every 2,500 miles. Cheap insurance.

Service manuals mostly require oil change at certain mileage or time period, whichever comes first. Some manuals also state that used in "severe conditions" (mostly rainy, dusty, etc.) then more frequent change recommended.
Since my exR1, I mostly use adequate, but relative cheap heavy duty oils, and I aim for 4000 km change intervals - my motto here that a high grade, cheap fresh oil is better in the engine than a pricey one for the recommended (manual) mileage.

(If money wouldn't matter, then I would drain & clean my engine oil with an external centrifugal oil cleaning system (one micron filtration), then have it analysed by a lab and reuse if it's clean enough and up to specs. With a fleet I would go in that direction.)

No harm...

Whats the harm in changing annually? Fresh oil keeps your engine and tranny happy! I have ridden all winter and was even advised I should have a different oil for cold weather. Certainly makes sense.

Short trips, short commutes, low mileage. In most motorcycles this is a recipe for moisture condensation to accumulate within the oil. The idea is at least once a year you should start with fresh oil, minus the condensation. It takes about 45 min of continuous operation at normal operating temperatures to "boil off" most of the condensation. This is never 100% solution and some engines do a better job than others.
To make a long story short; your riding pattern would result the "most benefit" from at annual oil changes. Especially if you live in a humid environment.
