Hi. I bought a new Harley Dyna a year ago. It has the 103 cu in engine. I bought a couple of HD filters and a case of the HD 20W50 Synthetic oil. Screaming Eagle, "SYN3". This oil can be used in the engine, tranny, and primary chaincase (clutch).
The bottle says..."Developed with a proprietary three-synthetic basestock formula......". Although I don't have a bottle of Mobil 1 handy, isn't this similar to how M1 discribes their oil?
Since HD doesn't make oil, I was wondering who does???
I have a 1937 Plymouth Pro Street car (has run a best of 9.89 sec in the 1/4) and is street driven. It holds 10 qts of oil (with 2 large Fram racing filters) and uses Mobil 1. Ditto for my 1965 427 AC Cobra. I have been VERY happy with M1!
However, I have already decided that Amsoil 20W50 is the way to go in the Harley. That oil is also suitabe in all 3 locations.
I was wondering if anyone has used the Amsoil Syn Gear Oil in the transmission and what the results were versus the 20W50.....
THANKS in advance!!!
