Hey all, anyone ever try royal pruple 10w-30 in a ek y8 sohc trans, jus wondering cuz my 3rd kinda crunchs every now and than at high rpm, tried honda mtf but found out its not like how it ussed to be......its like **** water if u ask me,,,lmk guys

 

Always heard GM Synchro or Honda

 

Redline MTL is supposed to be as good or better than syncromesh. I havent tried it yet but next week I'm going to try some since my 2nd is a bit scratchy...

 

I've been using that lucas additive with the honda mtf for my current transmission and it seems to shift a lot smoother and more solid than my previous transmissions. i used to only use the mtf fluid.

 

I am using Royal Purple 10w-40 in my tranny (D16Z6) and I really can't tell the difference between Honda MTF and the RP. Of course I have a shitty Luk clutch installed with a competition clutch waiting to go in.

If anything, any oil 10w-40 (synthetic only), RP Syncromax, Honda MTF. Don't use GM its not made for Honda's and I've heard so many people complain about GM crap.

DO NOT USE 10W-30, the tranny gets hot being attached to the engine, as well as gear rubbing and such, you want something that wont break down in head, 10W-40 ensures no breaking down of oil, and MTF is made for that high heat range.
