Im curious as to where in the USA can you buy Shell 20/50 motorcycle oil?Yesterday I talked to the fellow that had my Soft tail and he used Harley oil. Would it hurt to change to Shell 20W50. Who makes Harley oil The Shell oil is for Motor Cycles.
I also use the non V-Twin M1 20w-50.Mobil1 Syn V-twin works great, but I have a buddy who does 20K or more a year (and a lot out west on the deserts) who uses exclusively Mobil 1 (not V-twin) and has never had a problem. Only differences is V-twin has a bit more zinc and costs a helluva lot more.
Dexron ATF.May I ask what you choose for your primary?
Dexron III ATF.
Along with auto transmissions, Dexron III is also used in chain driven 4x4 transfer cases (NP207, NP208 etc)...
After all, what is in an automatic transmission? Clutches, bearings etc... ATF is also used in chain driven transfer cases (NP 207/NP 208) that have.... chains.
Sounds like a HD primary to me.
Some aftermarket clutch manufacturers like Barnett recommend Type F ATF, as Type F contains no friction modifiers.
But I don't know of any chain driven transfer cases that call for Type F ATF.
