Brecht -> Tornado fuel + OS engines (3/13/2005 11:02:43 AM)
|
Last year I bought an OS 0.46 FXi. A use Tornado fuel with 10% nitro. After 3 months the engine sounds a bit raw but still runs great. Last week I bought an OS FL-70. The shop manager told me that the same 10% fuel would do for this engines. Now I read in the manual that a fuel of no less then 20% castor oil is required. Tornado fuel only has 15% oil according to their site? Isn't this a little less oil for an engine. Isn't it bad braking in a brand new OS 4 stroke with fuel with only 15% oil??? Should I mix some extra oil in the fuel? Thanks
