What’s a common milage for synthetic oil changes?

Does anybody change there oil when light comes on?

 

I usually go 5K miles between M1 oil changes.

 

samehere...but i change the oil filter at around 3,000 and just keep the oil in until about 3000 mi later then I change both oil and the oil filter

 

I go four with M1.

 

I have only changed oil once and that was when the light came on. I use castrol synthetic for high horsepower. That oil change was about 5,000miles ago. Think its about time for a change though feals like its starting to lose power.....

 

Oil is cheap, engines are not. I go 3K, then do the oil and filter. But I run N20 and go to the track alot. If I was N/A and didn't race alot I'd go 4-5K.

 

I did my first one at 500km.

Next one at 4000km and that was right before storage.
