hi all, I bought a used 2012 yamaha 250 vstar a year ago. it had 285 miles on it. the dealer changed the oil before I took it. I did not change the oil at 600 miles. there's 3000 miles on it now. the bike runs fine.
#1, is there any issue missing the 600 mile oil change if it was done at 285?
#2, when I change the oil next, probably at 4000 miles, conventional or synthetic? the dealer said yamaha lube until about 10K and then synthetic.
I use the bike for short trips around town and occasionally longer rides.
