hey savages

Just bought 2 bottles of Redline 10w40 for the bike at around 50$ .. I thought it would be ok to sacrifice my money for a good quality oil, since oil changes is only once a year, and at the same time avoid the hassle of calculating and adding zddp... But, I don't ride that many kilometers so I was thinking, do I have to change the oil every year even if I've only ridden say 500 to 1000 km.? Still it's only once a year, but it would be a shame to throw out such good oil imo...

Thanks for the quick reply

Yes I put the bike away during the winther months..

It looks like I do need to change it once a year because of the build up of acid and other chemicals..

I need to ride more
