Is the synthetic oil for high mileage motorcycles only? Or can it be used for low mileage as well?

As song as the engine has been broken in & over 1500 miles u can use anything u want. I recommend synthetic & I will explain what made me a believer.
When I was a beginner on bikes, synthetic motorcycle oil was new. I did not make much money then & even though I loved my bike, if I could spend $10 rather than $25 with the same results that is what I was going to do. So a friend & I did a test. With the regular oil we set the idle at 1000RPM (on a bike with no computer & no fuel injection). We drained the oil, replaced it with full synthetic then restarted it.strangely enough the bike from then on idled at 1400 RPM. Since nothing was adjusted we concluded that because the engine internals were being lubricated better, it reduced friction & allowed the engine to spin faster with the same amount of fuel! I know its not rocket science but it made a believer out of me & I never used anything but synthetic since.
Synthetic oil DOES make a difference but if this bike is nothing special to you-it will run just fine on what ever u use. But, since motorcycles use their engine oil to also lubricate their transmission- use motorcycle oil. Car oil will make ur clutch slip over time.

Synthetic is fine for your bike I will say find a brand. Dino or synthetic and stay with it. Changing brands my cause your clutch to slip as all the additive packages may not be the same in the oils.

Modern synthetic oils will mix with good quality petroleum oils with no problem. However, doing this reduces the benefit of the synthetic. Assuming that the motorcycle is in good condition, changing from one to the other wo not do any harm.

Yes you can switch back & forth. Synthetic just gives much better lubercation and protection to the engine than Reg. Oil
ALWAYS change the Filter when changing oil.

I personally do not use it,but my friend swears by it. I understand that you should use a special oil filter designed for synthetic oils and you can not mix and match,but it does last longer between oil changes. Hope this helps!!!!!!!!!
