I do 1k then every 4k to 5k. I do use Amsoil. But any quality oil will work
Time does not affect quality of oil, only miles. Manual says change every 5,000 miles. If I rode mine only 1,000 miles per year, I would change it every 5 years. Oil does not deteriorate in an engine just sitting there.I use synthetic and I simply change it every spring. I don't worry about mileage very much.
LOL - deterioration and contamination mean the same thing. Even if there is a little, when you run it, it will burn off quickly w/o any harm.Oil itself does not deteriorate, but can get contaminated sitting in engine. Living in Houston, we have high humidity and pretty good temperature swings. This will cause condensation to build up in crank case. Is it minor, sure, but it's there. That's why manufacturers not only give mileage, but most set a time limit of change to once a year. My view, oil is cheap, change it either by miles or time.
We will agree to disagree on this. Condensation does occur in the engine case. The crank case is not as sealed as most think. You have a breather tube from engine to intake, moisture will and does enter the crank case in humid and temp swings. You are correct that bringing engine up to full operating temp will burn the condensation off. But does everyone ride their bike long enough for this to happen.LOL - deterioration and contamination mean the same thing.

Crankcases are pretty sealed. Unless your bike is outside during a hurricane, there won't be any condensation build up.
Absolutely does not happen in a garage void of the morning dew and rain. And even outside, un less it has sat for months or years, the minuscule of moisture will burn right off when you run it. Plus. such moisture is totally pH neutral. It is ONLY acidity that degrades oil.We will agree to disagree on this. Condensation does occur in the engine case.
