oil change intervals,time vs mileage

[TONYJUMP]

Feb. 2021 Purchase new 2020 C650GT
Oct. 26,2021 had 750 mile check up done.
Aug. 3,2026 As of today I have 3557 mileage and have not changed the oil.
That is 4 yrs 9 months since 750 mile check up,oil change.
I ride an average of 557 miles a year.
When should I change my oil?

The standard advice is to change engine oil at least annually regardless of mileage. I have some vehicles that, like your C650, don't do many miles and those I change the oil every 2 years, sometimes 3.

For the little it costs, just do it once per year and the filter every two, unless you live in dusty, arid area.
