## Customer Reviews

### ⭐⭐⭐⭐⭐ Life Saver!
*by S***A on September 16, 2019*

I have a 5th gen 4runner Limited and hitting 30k I decided to replace the fluid's in my differentials and transfer-case. Differentials are straight forward GL-5 gear fluid which I used Amsoil. Royal Purple states on their data sheet for the Synchromax as being a replacement for Toyota Genuine LF Gear Oil, I click on the add to cart so fast the lag in my wireless mouse almost gave me a stroke. We all know dealers like to markup the price of their stuff by a factor of about a trillion so this stuff is a life saver and I bet you both my kidneys Royal Purple is exponentially better than the $90/quart toyota stuff. So far, it's fantastic. Love it and thank you Royal Purple!

### ⭐⭐⭐⭐⭐ Smooth shifting in the Honda S2000 manual transmission.
*by C***S on September 9, 2019*

Honda S2000 owners tend to over-think and discuss lubricants. Found this allows smoother shifts than OE Honda MTF and is about the same price. Only negative is the bottle shape which does not work well with the little bottle pumps that fit US quart oil bottles.

### ⭐⭐⭐⭐⭐ ... supra with around 30k miles and it’s just as good as the stock feel if not better
*by D***S on May 13, 2018*

Installed in a 95 supra with around 30k miles and it’s just as good as the stock feel if not better. Shifts are smooth as ever and I couldn’t be more satisfied.
