Is anyone running Mobile one V-twin in all three holes? Would anyone recomend against that? I would like to because then I could by a big quanity of V-twin oil instead of a couple of different oils.
Thanks,

 

I'm on an '05 FLHTI, I have been using the Mobile1 Gear Oil in the Tranny... the 75W-90 is about the same weight as 15W-50, regular Mobile 1 for cars for the motor oil...

While the M1V Twin is in my opinion the best, I use it also, but would strongly advise against it in the trans. You need gear oil in the trans. I found that redline shockproof heavy (amongst others) works very well and you get no "fuzz" on the drain plug magnet at service time, which says a lot to me as far as wear.

 

Well, I have decided to use the Mobil one extended performance syn oil in my engine and primary. I just picked up the mobil one gear oil for the tranny.

I miss placed my bible does anyone know how many oz go in the primary and tranny on a evo softail?. Can anyone help me out?
Thanks,

'89 & earlier - 1.5 quarts
'90 - 30 -36 oz.

I ignore that stuff, put bike on side stand, & fill 'til the juice just touches the bottom of the clutch basket.

But then I use Ford ATF
