You've spent your hard earned money on one of the most popular motorcycles there is, Harley Davidson. You purchased every option you could think of to make yours special.
Harley oil is good, but AMSOIL is the best. You will be able to extend your drain intervals, extend the life of your Harley, save money and "maintain your warranty". Please read our Warranty Laws section of this website to learn more.
We now have the latest test results comparing the new H-D Screamin' Eagle Syn3 to AMSOIL 20w-50 Motorcycle Oil.
The suggested retail price for the H-D Syn3 synthetic is $8.25 while the suggested retail price for the AMSOIL 20w-50 Motorcycle Oil is $6.55. AMSOIL change interval specifications are two times that of the H-D Syn3 synthetic.
H-D Screamin Eagle Syn3 has three years of bench testing and 230,000 miles
of durability testing.
You deserve the best. You deserve AMSOIL.
One of the most common questions we are asked is what is the recommended transmission lube for Harley-Davidson, both big twins and sportsters?(see chart below)
These recommendations are, in our opinion, superior to using one oil in all three areas as H-D recommends with Syn3. While you can certainly use AMSOIL 20w-50 motorcycle oil in all three areas (engine, transmission and chaincase), it is our recommendation that it is better to use the specific products outlined above for superior performance.
AMSOIL Synthetic 10W-40 and 20W-50 motorcycle oils give motorcyclists what they need: Superior wear protection for high- stress motorcycle engines and transmissions that stay clean and deposit-free.
Please beware: Prior to H-D releasing a synthetic we have found that many Harley-Davidson dealership technicians are telling customers that synthetic motor oil is "too slippery" and can cause flat spots on roller bearings because the bearings won't turn.
Synthetic motor oils are no more "slippery" than petroleum motor oils. The tractive coefficient, which is the measure of the case with which a lubricant facilitates sliding, is essentially the same for both petroleum oils and synthetics.
Synthetic motor oils are also used in many production and racing cars that have sophisticated roller follower technology and they have absolutely no problems whatsoever with roller bearings not turning.
This should also make you wonder why, all of a sudden, H-D is saying "NO PROBLEM" to using Screamin' Eagle Syn3 synthetic oil on your H-D roller bearings.
Unfortunately for H-D and all their riders, they did not have AMSOIL manufacture a synthetic oil for them. Once again H-D oil (Screamin' Eagle Syn3) looses to AMSOIL in the 4 ball wear scar test by leaving a scar 79% bigger than AMSOIL.
