I have a 00 kx 250 and a 03 kx 250.I have been using mobil 1 15/50 car oil since 98 in my 98 kx 250. I have tested a lot of brand name motorcyle oils and non motorcycle oils.Now this is not a scientific test just hardcore performance testing. I get the best shift's with the mobil 15/50 before they came out with the mx4t. I ride at the local track with heavy sand my shift's are consistent and smooth with the mobil 15/50 and mx4t. The sand is a good test because of the drag and resistance ,my shifts are made with full throttle and a slip of the clutch after many laps.My cases were split on my 98 before I sold it THE GEAR SETS looked beautiful the shift forks had no wear marks what so ever,2 hard years on this tranny. I replaced the clutch 1 time and the basket.Getting to my point other oils would resist a powershift in the sand after I started cutting some heavy laps and I tested a lot of big name brand mc specific oils.I have been using the mx4t in my 00 and 03 kx 250 the only reason I changed is because of the higher levels of phosphorus and zinc levels,in the mx4t. The oil is a excellent performer just like the 15/50,but at 7.00 a bottle changing my oil every 2 rides is getting a little expensive.I went to walmart last night and have decided to try the delvac 1300 super at 5.88 a gallon.From what I am understanding it is a great alternative. I know it is not syntehtic,but from what I have been reading the shear stability is excellent. I will post my results.
