Lucas 85-140. Especially running that in higher temp
So as far as anyone knows, there are no friction modifiers or other additives to make diffs lock/unlock smoother in the Honda oil? I haven't read up on how these diffs lock and I'm assuming it's not anything like an automotive locker like my G80 on my Chevrolet. If you run regular gear oil without any friction modifiers in a G80 you'll get all sorts of grinding noises while turning a corner. And a huge "bang" if you spin a tire.

Wouldnt thinks so. ive had no issues and haven't heard of any. Def quieter. I know my Dana 80 will get noisy without too but it's limited slip

I had to add a friction modifier to a limited slip dif due to the clutch plates. it would chatter when I started from a stop and was turning at the same time. Changed oil and added the friction modifier and problem was gone. I did not know it was ever added to a dif without clutch plates.

Yeah. When I hit about 60,000 miles, my truck would chatter while turning from a stop. Turns out that the friction modifiers broke down after a few years. I replaced it with the same OEM GM diff fluid with the friction modifiers already in it. Oddly, I have 125,000 miles on this diff fluid and no chatter yet. Maybe the wear from the break-in period contaminated the fluid from the factory? Anyhow... I think I'm gonna go with the Lucas in my Honda. Thanks!

Will not need it. The G80 is an Eaton Gov-Lok that uses friction plates like a limited slip along with fly weights.

The differential locks in the Honda use a dog clutch (sliding gear) arrangement that works like a tractor locking diff (or ARB or elocker). In the case of the Honda, it is actually closer to the cable actuated lockers that Toyota used in Land Cruisers everywhere but North America.
