Redline gear oil can help

It could be on the track your gear oil was getting abit thin with the extra heat thus causing problems

Yep, I think Reline 75/90 was what I see most people are using. Thanks for the all the advice everyone, and Jon I may hit you up on that. I'm guessing the 22mm bolt is hard to get to ? Or just an extension on a ratchet will do ?

I tried Redline MT90 as a cure for a 2nd gear crunch on my Skyline and it didn't help. Be careful what type of oil you choose as Redline have a few different types available.

Why would u think that an oil would help worn out syncros ?

Not so much a crunch, gears 1 and 3-6 engage smooth as silk but 2 requires a bit more effort before it slots it. I have used Redline in the past to smooth out tired gearboxes on Skylines, I believe the oil is from their Shockproof range but mixed with another one of the oils, i cant remember which one. I'll be trying a Redline Shockproof mixed with MT90 next.

To revive this thread a little bit, do you think its worth it draining old oil, filling up with multitrax take car for a 30 min drive or so to mix any old oil that wasnt drained with the first lot then drain and then fill up with some syntrax?

Or waste of time and money?
