I know this has been discussed a bunch on here and I have done some research as well, but what weight of oil are you guys running. I plan to use Mobil 1 V-Twin, Amsoil, or Redline. Probably in that order as well since I beleive that the Mobil 1 will be easier to find. Also what weights are you running in the Primary as well as the Tranny, I know that these do not need to be changed at 5000 miles but will need the info later on. Thanks for the help and I dont want to start a fight among you guys here so keep it nice.

I run:

Redline Heavy shockproof 75w90 gear oil for transmission
Mobil 1 20W50 oil used in engine and primary chaincase

Very happy.

 

Mobil 1 20W50 engine
amsoil 10w40 primary
bel-ray 85W140 tranny

 

mine 20-50 mobil1 v twin

 

Ran Redline in all 3 boxes at the last change and I couldn't be happier with their products. I'm even seeing HD dealers carry them on their racks now.

You might wanna pick up a CORS while yer at it, IMO it's worth every penny of the $20.

 

AMS 20-50 oil
AMS severe gear 75-140 in the tranny
H-D formula+ in the primary.

 

Mobil 1 20/50 in the motor
Mobil 1 75/90 in the tranny
Mobil 15/40 diesel engine oil in the primary

 

Explain this CORS thing to me. I dont quite get how it removes the old oil and leaves the new? Also is it reusable? I gather that it takes the place of the oil filter while it cleans the oil for a couple of mins and then you remove the CORS and replace it with the filter

 

What did you ask? I cant see past your avatar.

Been happy so far but oil changes get expensive at 10 bones a quart.
