“I used this in my 2007 MX5 gearbox instead of the Castrol oil I had put in there less than 2 years ago, (it was in line with the specification required). The gear change was really notchy and difficult with Castrol and I had read that MT90 would solve this, so I gave it a try. The change is like night and day with my gearbox performing perfectly through all the gears, hot or cold. As others have said this oil is a bit more expensive but totally worth it given the results !”
“Replaced oil in Fiat 124 Spider gearbox with this oil. Much smoother gearchanges now and greatly improved the 'notchiness' - both when cold and when warmed up.”
“Discovered that my car should have a GL3-GL4 oil in the gearbox. Switched from the previously used GL5 oil and the gear shifts are much smoother thanks to the correct oil.”
“Forget the rest...buy the best !
Oh dear, that is so lame, but it's true. This is THE oil to use in your gearbox especially if it's an MX5 NC.
It's not the cheapest, but who wants cheap over a transformed shifting 'box ?”
“The oil definitely improved the notchy changes I was experiencing, engaging reverse is now crunch free and the changes from first to second gear are greatly improved.Overall I am impressed with the improvement and would recommend it to anyone with a Mitubushi Colt experiencing notchy changes.”
