I’m getting ready to change my oil, what is the best oil made for the GL1800???? :?:
Here's my little secret: Go down to one of those places that accepts used motor oil, sometimes you have to go after hours, and wait for someone to drop off a gallon of the oil that they took out of their car, motorhome, tractor, boat- whatever. Chances are that that oil will have only a few thousand miles on it. Take that oil home and use it in your bike. Save you lots of money and hey! It good for the environment as well! You may want to get you a new filter every now and then but that up to you.
