hi all from australia,what would be the best grade of oil to run in a ttr 250
Hi dija. I use, and have mostly used, 15W50 full synthetic, and change it religiously every 1000km. However, in the interest of commonality I now use Yamalube 15W-50 mineral oil. It seems fine, though it does use a bit more than the synthetic stuff. But it's done a lot of km, so who cares? Bike still sounds like new. Amazing.
