Just called local bike shop. Harley installs convetional 85/90 gear oil purchased from cheapest supplier. Harley does not make their own oil they claim has to be used in their bikes. That info. was obtained from an Amzoil web site. As an Auto Tech. of 34 years I know that different oils are used for different applications for a reason. The use of synthetic or conventional oil should be based on facts not opinions!
80W 90 if using conventional. If using synthetic, 20W 50 will work. Also harley has Formula +.
75w90 gear oil, synthetic or non synthetic
It can be. The 5w20 is the weight of the oil which you can buy conventional or synthetic. If it is synthetic it will say so right on the container. If it does not say synthetic it is conventional oil.
Yes, you can even mix synthetic with conventional oil.
mobil 1 75-90 synthetic or reg
no...but you can use screaming eagle synthetic oil in both the motor and the transmission which is supposed to be better anyways
It is a combination of synthetic oil and conventional oil.
It is conventional oil and contains no synthetic oil. 3000 & 5000 are part synthetic and part conventional. 7000 is a full synthetic oil.
I will change my oil from conventional oil to synthetic oil on my next oil change.
Semi synthetic or synthetic blend is a combination of synthetic and conventional oil. Full synthetic oil is just that 100% synthetic oil.
You can use synthetic, synthetic blend, or conventional oil. It is your choice.
Synthetic and conventional oil can be mixed and used with no problem. That is exactly what a synthetic blend that you can buy is. A mix of synthetic oil and conventional.
