N12 Turbo Forums

Had a bit of a look through the search function and couldn't really find much on this topic.

For those guys who are having success not breaking our 20 year old gearboxes, what oil are you using?

I know benny was raving on about a nulon additive which i will add also but what oil should i add that too? Brands and weight would be perfect thanks guys!

Nulon additive is great. I mix it with Castrol VMX and have no problems at all.

yeah ive been using syntrax with the nulon additive. so far so good

same here, I used Castrol full synthetic manual gear box oil plus nulon. The gear select feels heaps more smoother. but it could all be in my head lol

I use whatever 80-90 EP gear oil I can find. I dont give a toss what brand.
No amount of magic potions or snake oil is going to prevent a gearbox breakage.

i'm using penrite 80w-85. i drove around on just new oil for a few days last week and i had some troubles getting 1st and reverse, and 2nd to 3rd sometimes crunched a bit. i put that nulon g70 stuff in again and wow its nearly perfect. it really is worth the <$15

I changed from Castrol VMX to another brand (sorry can't remember what). It was the same weight oil but when the gearbox/car was cold it would grind a bit changing down gears.

So i dropped it out and put the castrol back in. No more grinding.

im running fuchs oil really good shit

I'd only recommend the manufacturers spec oil. Then within the spec I've valvoline in the Exa (80-90w) and had it in the MR2 (75-90W). I just changed the seals and reco'd the MR2 driveshafts and put Castrol in. It is definately more "knotchy" than before the change, but still seems fine....

I would be surprised if there were indeed as much variation between oils as most seem to think. I use any correct weight I get my hands on.

But................................

I have heard that you can run tranny fluid as a replacement (opinions?)
or even better, jam a banana skin in there for a smoother shift, apparently.
