My Maintenance Minder is saying that I need service B6, I have 10,000 miles on the car now. 6 is the message to change the rear differential fluid. I've never had to replace that on any car before, I'm guessing it has something to do with the SH-AWD. Has anyone had it replace and what does it really do? how much did it cost? Thanks!

This must be your first honda product. You must change tranny fluid,differential fluid in Honda/Acura as they are NOT American Chevy tranny's that can go thousands of miles without changing those fluids.....

I'm not sure what the interval for the RL is under normal circustances, but normally it should be around 30k miles. Now the TL and RL do comes with many sensors and calculates many data that myabe because the way you dirve or whatever the reason it determined that you needed it now. It could also be that something trigger the minder. Have it check it out at the dealer.

I've been in touch with a chemist at Specialty Formulations and will report back to you folks on a suitable fluid for this application.

Please share your findings. I've been using Mobil1 75W90 and/or LE607 every other oil change in my S2000.

I don't feel like running into the car to grab the owners manual, can someone tell me what SAE weight do they recommend?

Also, if the RL is anything like the S2000, differential fluid changes should be a snap as long as you have the right tools - 23mm wrench and a decent pump.

5W20 on the RL....

Actually, this is my 3rd Honda/Acura. First was a 2000 Accord EX-V6, 2nd was a 2004 TL. The 70,000 miles I put on the accord, never had to change the diff fluid. On the TL, drove it fro 20,000 miles before I traded it in for the RL. Spoke with the Service manager and he said that it's because of the AWD that it's changed more frequently. Car is going in for service today and installation of a new deck lid spoiler.
