can this be used in the primary also?
Dan M on Aug 10, 2016
BEST ANSWER: I asked this same question becasue I heard this was the same as the primary oil, do NOT use it in the primary! This is the response I got direct from Bel-Ray:

"
You heard partially correct but not entirely. The Big Twin Transmission Oil is the same as our Gear Saver Hypoid Gear oil 85W-140 and the Primary Chaincase Lubricant is the same formula as the Gear Saver Transmission Oil 80W. So the Big Twin Transmission Oil is correct for a Harley-Davidson transmission case, but not for the primary. In the primary, a product like that would cause clutch slippage and poor shifting performance. So for the primary you want either the Gear Saver Transmission Oil 80W or the Primary Chaincase Lubricant, which is a formula that excels in wet clutch applications and performs very well at keeping the heat down in the primary. If you have any additional questions please do not hesitate to ask."
Will this work for a 2009 HD Road King (FLHR) transmission?
Elijio J on Feb 20, 2017
BEST ANSWER: Yes, it is the equivalent of the H-D oil. I also recommend the primary oil, equivalent to the H-D "semi-synthetic".
I have seen clutch slippage & failures usint the new H-D "all in one" oil for both primary & tranny.
Good taste in bikes: I have an'08 FLHR and a '92 FLSTC, both are fed these products & perform well!
Is this the same as your 85w140 hypoid gear oil?
A shopper on Mar 27, 2018
BEST ANSWER: Yes, it is the same except for extra additives. Good stuff.
is it full synthetic?
A shopper on Mar 25, 2018
BEST ANSWER: This is NOT synthetic. It is "petroleum based" with a strong additive package (5 to 10%)
It WILL work well in a big twin transmission, but I personally use & would recommend a synthetic oil for the primary drive to take the heat of slipping the clutch.
