Hey there hows it going? I have been just wondering about engine oils. I am running a 2015 KTM 450 SXF this year and they call for their Special Motrex oil or a Bell ray oil for best results. At $100.00 bucks for a jug and you might be able to get 3 oil changes done out of a jug if you don't spill a drop. Just wondering if anyone using a Shell Rotella full synthetic T6 5W/40 in the KTM's much cheaper in the long run. But I also don't want to risk hurting the motor at all so if everyone is using a Motrex or the BellRay that's what I will continue to run. Thanks for your help. I ran a KX450 last year and had good luck with my Motul oil as well.
