Recommended Yes: 2 / No: 2

From RP website:
Max-Gear is an ultra-tough automotive gear oil. It's designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler and longer without overhauls. Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple's proprietary Synslide additive technology. Max-Gear is recommended for use in truck, motor home / RV, and automotive front or rear differentials, manual transmissions, and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. All viscosities of Max-Gear are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.

Pros Great information out ther about it
Cons Performance in my AX-15
Recommended no

Comments: I decided to try out RP after reading comments about using GL-5 lubes in the AX-15 at www.stu-offroad.com. I went with RP because of all the great things I have heard and after reading the product data sheet found here http://www.royalpurple.com/gear-oil-pp.html

Results? I should have stuck with the Mobil1. My AX-15, like many others, is a pita :). I thought the Max-gear would be of benefit....it's shifting rougher now then it ever has.

I have also thrown the max-gear in the diffs....so far so good there.

Pros fancy color
Cons short life, causes very bad shifting once the oil expires
Recommended no

Comments: well I first tried Royal purple after hearing good things about the stuff, and for a while it worked just fine in my AX15 transmission.

but after about 9k miles on it, my AX15 began to lock me out of any gear after coasting to a stop and trying to shift into gear from nuetral (mind you, this is a brand new AX15 with about 10k total miles on it). Fearing the worst, I began to diagnos and first changed the oil.....low and behold my AX15 worked perfectly fine after that and never had shifting issues again.

I changed the oil and got rid of the Royal Purple junk and went back to using Pennzoil Synchromesh that I had used just fine for a long time in my old AX5.

oh and for the record, I was using Royal Purple Synchromax oil, not max gear, but Synchromax isn't available, so I posted my review here.
