View Full Version : Which oil do you drive in your ironhead?

Hey guys.
Since three years I'm running my 1980 Sporty with the SAE 50 motoroil.
Does anybody know if there is another oil I could possibly put in it? Like a 15w40 or something else?

I hope the oilclassifications are the same in the states as in germany.

My Ironhead didnt like the 40 weight. Just a little to thin I think. Stay with SAE 50 weight.
