Can I run Lucas 20w-50 full synthetic in the engine , primary, and trans .

I want to keep it all the same if i can .

Also double check me if you will .. is this correct ...
3.5 quarts for engine and filter
24 oz for trans
and primary I haven't found that yet , so if you know the amount I would greatly appreciate it .

 

Primary is 24-26 oz I believe. The engine will only need three quarts at the very max as 3.5 is for a dry engine. I always add two quarts to the engine, let it run for a minute, check the level and go from there.

Thanks Drew . As for the trans am i correct in that its 24 also . Im still learning the Harley . Im pretty mechanically inclined , just want to get my ducks in a row .
3.5 quarts for engine and filter
24 oz for trans ????
24-26 primary

Also IS it ok to run lucas 20w-50 in ALL of these ?

 

Anyone ? Need to punch this oil order but what to be sure

 

20-50 ok for the engine
Tranny 85-140 gear oil
Primary up to you but do not use motor oil..it has additives and your clutch will slip..

 

Why? . .

 

Just so I dont have to buy 3 different oils

 

so is it 24 oz for the trans ?
and 24-26 oz for the primary ?

Lucas seems to be the one I want to try for the oil . and i know its 3 quarts . The other I need to find out how much and what would be recommended .

 

I run Amsoil 20w-50 in all three holes. I ride pretty hard and have been very happy with Amsoil!
