Using 10w40 Mobil one fully synthetic motor oil

Post by jcreedenjr » Sat Oct 13, 2018 10:02 am



Owners manual states 20W40 motor oil for 1995 Goldwing which I never had trouble finding sold by Mobil One fully synthetic. It now seems to no longer be available. . Will using 10W40 be a concern?

Not at all, in fact a good number of us are using 5w40 synthetic Diesel oil (Rotella).

Check to confirm the bottom half of the API donut is blank (no friction modifiers), or the clutch won't like it.
They say 98% of all Hardleys ever made are still on the road..... The other 2% made it home. :lol:
(I stole this from somebody on another GW site...) :roll:

DenverWinger, Thanks for the information. I was hoping there wouldn't be any concerns.

I am using Rotella T6 in 5w40
the 5w or 10w just ensures that oil pressure comes up fast.

my car is spec'd by GM at 5w20 and has been on full synthetic since new 11 years ago.

Here is what I just used in mine. As Denverwinger said, no friction modifiers.
Mobil 1 High Mileage doesn’t contain them.
WingAdmin has an oil change how to that shows this oil.

Yup, I have been using that oil for many, many years. My GL1500 loves it. Not a lot of auto places carry it, but Wal-Mart always does, and it's cheaper than anywhere else.
