Harley Davidson Softail Oil
Oil question…. Yup that question haha. Heard that Lucas oil is the go and to stay away from synthetic oils for a 103 motor due to bore glazing and early failure. Got this info from a mechanic that has done many harley rebuilds over the years (about 30 years) and has seen the damage first hand.
Question is i got myself a 20w50 for the motor and gearbox however went with the Lucas primary oil. With the primary oil do i just use this straight in the primary or mix it with the 20w 50. Know it’s a strange question but it says on the rear of the bottle it’s not a lubricant which seems a bit miss leading haha.
Anyone know what the go is?
