Hi All, Some Questions if any of you can help answer them about OIL??? I brought a Case of Motul Synthetic Oil 10W40 4T for my Bikes thinking it is Better to Run Synthetic right??? After Running my Pantera's in on standard Oil I serviced them all and Replaced the Oil with the Motul. After the First Trip less than 1000 kms the Oil was Jet Black??? so i replaced it again and went back to the Standard Oil. These were Hard Off Road Kms. I also serviced my Yamaha Raid and used the Same Motul Oil, have done about 1500 kms, very easy Road kms and the Oil is Black again??? I Spoke to Justin last night and His Kawazaki with the same Oil did exactly the same, Turned Black so he replaced it with standard Oil. Both of us agree though the Bikes Ran Smoother and Quieter (with Less Vibration on the Pantera's) with Motul compared to standard Oil. 1, Is Motul Oil Shit ? 2, Turning Black indicates Overheating so it needs changing right ? 3, Has anyone had similar problems ? 4, Any suggestions on Better Oil more readily avalible? 5,Gypsy Rider uses Mobil 1 5w50 for his KTM's but i have read this is not suited for Bikes and can cause Clutch problems in some cases??? Your Views or Opinions would be welcomed Gentleman. Cheers Ian.
