Sunoco, makes Harley Davidson engine oil
yes, though this is only recommended if the bike has been through its break-in period
I am not sure of viscosity, but if you have Harley Davidson on your fuel tank, you should use Harley Davidson lubricants. H. D. primary and trans lube or H.D. 20/50 synthetic motor oil will work just fine.
no...but you can use screaming eagle synthetic oil in both the motor and the transmission which is supposed to be better anyways
The recommended type of oil for a 2003 Harley Davidson Sportster 883 is 15 W 50. This oil can be purchased at any cycle shop and most auto parts stores.
10 Psi is all that's required..the Harley engine needs oil Volume..not pressure..the lifters rquire 8-10 psi of oil pressure...Use a Synthetic oil..not the mineral .
