New Gearbox Oil?

[Abo Bob]

Well since we're all talking about it. I have an older gearbox with some cheap unknown oil in it. Box has around 230-250k on it. On sunday at the drags as the day progressed it got harder and harder to get into 2nd gear from high revs. I had to shift below 7k and that worked but late in the day even that wouldn't work. Crunched 2nd gear bad and wouldn't go it even.

I picked up some Motul Motylgear semi-synthetic 75w90 for $12 per litre. See how it goes and change it every 10-15 thousand.

On the label it says its an extremepressure semi-synthetic oil that is designed to reduce gearbox's that are difficult to shift or are notchy.

Mind you even the Gear300 says the same thing.
