[QUOTE="bigred455, post: 830044, member: 19827"] First of all, this is not about which oil is better. This is about which ratio I feel provides adequate lubrication for my riding style - MX. In fact, the Mobile MX2T piston looked the best at 32 :1, but I do not care for MX2T (won't go into details). At 40: 1, the Klotz R50 looked good, no scratches, but things were getting a little shiny on the intake side.I was happy with it though. I do go over my jetting each change I make to my motor Amsoil 50: 1.....well...you can see for yourself. Heavy scratches on the intake side. All the top ends were serviced at 45 to 50 hours on a 2003 KX250, B-rider, MX only. I am currently testing the Amsoil for a second time at 32 to 1.Just to prove my point! I do not believe in 50:1 ratios(for mx anyway)Please save the dirt or water comments for someone else. As I explained earlier in another post, if you look at the scratches, they are forming inline below the piston ring locating pins. The KX cylinder has an aggressive intake port. I believe that the center of the piston swells into the intake window of the cylinder where there is no support. If you look at the pistons below the locating pins, it rides on a thin wall and this is where all of the support is centered. You need all of the lubrication that you can get. The KX250 cylinder, I believe, is excellent at testing oil ratios. Not all porting layouts will show such results. I do think the Amsoil is a good oil,but the ratio is a bad suggestion for anything more than trail riding. I will prove this when I pull my topend with the 32:1 amsoil. Note: The black line you see under the piston window is just magic marker. Keith 455 "LET'S JUST RIDE" 03 KX250 [/QUOTE]
