The label on the Honda synthetic motorcycle oil I have been using in my NSU 1200 engine (practically a motorcycle engine anyhow) touts its favorable effect on dog gears. Of course, that left me wondering what its effect on synchromesh would be, so I wondered whether it would be appropriate for my Mini Cooper S race engine/gearbox combo.<div class="ydpf5ed608byiv4501719512"><br class="ydpf5ed608byiv4501719512" clear="none"></div><div class="ydpf5ed608byiv4501719512">I have have heard good things about Redline Shock Proof Gear Oil’s ability to keep gearbox temperatures down: <a class="ydpf5ed608byiv4501719512" href="https://www.redlineoil.com/shockproof-gear-oils" target="_blank" rel="nofollow" shape="rect">https://www.redlineoil.com/shockproof-gear-oils</a> .

But there are some drawbacks :9.5kgs weight penalty and the gap between 4th gear and 4th overdrive gear is too big. There is also a considerable amount of power loss when the overdrive is engaged because of the friction in the overdrive gears : but I think that in general modern engine oil can reduce the friction in the overdrive, compared to GL-4 gear oil, because it has much better friction modifiers. But are these friction modifiers compatible with the clutch in the overdrive?? Classic Mini's and most bikes have 1 oil pan for both engine and gearbox : what about using a modern bike oil or a modern (synthetic) classic mini oil in an overdrive gearbox to reduce the friction in the overdrive and gain some acceleration when 4th overdrive gear is engaged?</div><div class="ydpf5ed608byiv4501719512">Marcel</div></div></div>_______________________________________________<br class="ydpf5ed608byiv4501719512" clear="none">
