I just bought one of these scooters on Steroids. Its a 638cc twin 4 valve engine. It has a devorced engine and transmission. The engine is 2.7 US Qts and the trans is 12.3 US OZ's, yes OZ's. Both call for 10W40 for normal usage, 20W50 and 15W40 is listed too. I am wanting to know if a C4 rated 15W40 Deisel oil would hurt? This has a Centrifcial (SP) clutch and a CVT transmission, no gears. The final drive is comprised of 5 gears, one after the other in a 90W gear oil bath. I am going to do UOA's on this and post them for other Burger King riders. Any recommendations? I run Delo 400 or Rotella 15W40 in most of my lawn equipment and they are my first picks.
This is one fast scooter and gets 50+ MPG at a cruzing speed of 75 MPH. I had it up to 110 MPH on a private driveway before I let off. DaveJ
