Honda A6 maintenance code

A is oil change. 6 is rear differential oil change.

Why would I need a rear differential oil change at 8200 miles? I was quoted $127 by the stealership. Seems a little bit much and a lot too soon.

Opinions?

Don't see anything at the 7500 mile service that states rear diff oil change..

Below, you’ll find the mile markers for the Honda CR-V service schedule:

7,500 / 22,500 / 37,500 / 52,500 / 67,500 / 82,500 miles
At the 7,500, 22,500, 37,500, 52,500, 67,500, and 82,500-mile markers, you’ll want to bring in your Honda SUV for service for the following:

Check and replace fluids
Oil and filter change
Inspect tire treads
Check tire pressure
Rotate tires
Brake inspection
Lubricate throttle linkage

Mark, FWIW, Honda's a known to get a growl sound when the rear diff oil isn't changed at about 20k miles. I think you're fine at 8200, but keep in mind to change it when the time comes.

I've on my third CR-V.

There's a conversation about it on the CR-V owners club. Apparently, Honda wants you to change it at 8000 miles after initial wear.

Perception

Is that the standard service interval for the differential, or just the initial interval.

I would guess that the short initial interval is because they use some form of assembly/ break in lubricant, and that they replace it with the normal differential oil at this time.

"The people hate the lizards and the lizards rule the people."
"Odd," said Arthur, "I thought you said it was a democracy."
"I did," said Ford, "it is."
"So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't the people get rid of the lizards?"
"It honestly doesn't occur to them. They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates the government they want."
"You mean they actually vote for the lizards."
"Oh yes," said Ford with a shrug, "of course."
"But," said Arthur, going for the big one again, "why?"
"Because if they didn't vote for a lizard, then the wrong lizard might get in."

Honda wants it done early for the first change.
After that, it goes to a more normal interval. I've heard they use a break-in fluid.

Rear diffs on these cars do need their special synthetic fluid changed, but it's more like 50,000 miles. These diffs freewheel until wheel spin is detected, then lock in (i.e., couple the axle shafts) electrically, and sometimes shudder in turns if the fluid degrades. Unless the owner's manual says different, I don't know why they would need any "break-in" oil when nothing else has it. Reset the monitor and forget it.

Should you need this service, it's a simple drain & fill. Buy the fluid from Honda. You'll need a little pump for the filling.

It’s listed at 15000 miles though. The service manager confirmed it. Do they suggest it early for convenience … or … something?

This appears to answer your question.

I’m going to look for a Genesis G70 owners club.

Serious about crackers.

If it's under warranty I would service it at the recommended intervals and keep the receipts.
No proof of maintenance is the easy button for denying a warranty claim if you ever need it.

Two quarts of Honda Dual Pump Fluid II is about $30, then a $6 pump and a couple bucks for crush washers.

I think you are right the first is 15,000 miles then every 30,000. I have a 2019 crv with a 1.5 engine. Bought it used and I remember looking up services and that one being done earlier the first time. I bought mine around 22,000 miles and just did it as I didn't see any record of it being done.

I'm pretty sure the OP is reading the codes on the Maintenance minder. And it for sure says change the rear diff with a 6. So I would change the rear diff. I don't see anything in the manual that overides the maintenance minder in this area.
