TC,
Now that Harley is not longer selling their primary fluid what you going with? You going to use their new stuff or switch over to a regular motor oil. Did my other two fluids ( Mobil 1 15-50) Crank and (Mobil 75-90) Tranny. Still up in the air on the primary.
Could not find any HD primary fluid at dealer. Local stores also did not have any of the listed items used by members here. Would standard Mobil 10w- 40 be a good choice?
Or should I stick with a syn like Mobil 1 15-50.
Thanks for all you add to the forum.

 

20/50 V-Twin Amsoil, Primary,and Crankcase. Amsoil Severe Gear Oil in transmission. Mobil1 V-Twin 20/50, and Mobil1 Gear oil would be my second choice.

My two cents.

 

Roaddog ....I'm sorry I didn't get back to you sooner.

If the primary oil is not available from HD any longer, I would prefer a non synthetic motor oil in the 10/40 range myself of any of the popular brands in the primary. You don't want an oil with a friction modifier in it.

 

Didn't the MOCO have a recall on the syn in the primary?

 

What is the part number for the HD Primary Oil in the poll? Thanks. Is it the Formula+?

 

Didn't the MOCO have a recall on the syn in the primary?

i don't know if they did or not but tc said they no longer recommend it for the tranny and after reading all of the posts i think i'm gonna go with mobil 1 v-twin 20w/50 in motor mobil 75/90 gear oil in tranny and just plain ol mobil 10/40 in primary and maybe my bike will actually shift a little nicer?? and truly be protected i should have known better than to listen to the stealer..lol

 

That's part # 99887-84 (old style)

 

For those of you who picked Mobil 1 in the primary, pls PM me with which Mobil 1 you use, 20W50 or 10W40. Thanks.

 

I use Rev Tech not because it says use in Harly davidson, It's all she knows.2000 RG tricked out .

When you say plain ol Mobil 1 10/40, is this the Mobil 1 MX4T motorcycle oil? It is used by many metrics with the crank/wet clutch together. If not MX4T, which Mobil 1 10/40? Thanks.
