## Description

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 Synerlec 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.

Review: Awesome product - I used this on my skidoo gear case. I always use this product for my machines. It does the job and I have never had an issue when I do use this. Others are definitely cheaper, but when your on a trail 50 km from home it’s nice to know this isn’t going to be the reason you have to walk home.
Review: About Royal Purple brand - I get the items very very fast And I so happy because it's really help me with my car. I can see how deffrent my car now between before I ll only and always use this bran 😊

## Questions & Answers

**Q: Always use luca 80w-90 in ford ranger 2.3l, 7.5" rear diff.  wanted to try this.  any issues with it being a 75w vs 80w?  is this better than lucas?**
A: I use the royal purple 75w-90 in my RAM 2500 differential. My differential is made by American Axle Manufacturing and I talked with one of their mechanical engineers who said the viscosity requirement is determined by several criteria with ambient and operating temperature being big determinants. I live in a warm climate so he said I could use a heavier weight oil. With that knowledge I don't believe there is a big enough difference between the 75 and 80 other the better lubricity at lower ambient and operating temperature. He did recommend amsoil but said the royal purple is just as good.

**Q: I have graphite/ composite  synchronizers in my  transmission , will they be damaged by the use of  anything other than the "Castrol syntorque" recom**
A: I've had the best experience with Redline MT90 in manual transmissions. RP was not working well with syncros (grinding gears when shifting).

**Q: I know that the product description says that it is not for use in wet clutch systems, but will it be okay for use in motorcycle final gear (shaft)**
A: Will be fine as a motorcycle final gear oil. I use this product in two BMW motorcycles, a BMW R1150RT and a R1200S, as a final drive oil and also as the transmission oil.

**Q: Will it work in a bmw x-3 transfer case, the manufacturer calls for their fluid # TF0870?**
A: No. Use the BMW fluid.

### ⭐⭐⭐⭐⭐ やっぱりロイパは良い
*by カ***ソ on 11 April 2025*

FF、機械式LSDの車両へ使用、ギア比変更後音が大きくなり困っていたので良いのが無いか探しまくった結果これに決まりました。 今までカス○○ール、ニュー○○ク、クス○、と試してきたが一番良いです。唸りも耐えられるレベルまで静かになりギアの入りもスムーズでLSDのチャタリングも少しする程度、まさに私には理想の商品です。
