Mixing gear oils?

Bryn · Mar 23, 2017

I've drained the gearbox for an oil change..

I have a litre of halfords GL5 80/90 mineral

800ml castrol syntrax synthetic 75/90 GL5

And 800ml CastrolSyntrax 75/140 synthetic limited slip GL5

Any harm in using the 75/140 and topping up with the non LSD 75/90?

Just tring to use what I've got :thumb2

use what it says in your manwell and keep the other stuff for lubricating the linkages

Thanks for the replies chaps....decided to fill with the Syntrax 75/90 fully synth...and topped up with the Halfords 75/90 Dino...they're both GL5 so I'm sure the bike will appreciate it :thumb2

You can tell I've had a crap nights sleep....just finished the oil change

Aye, that thick stuff takes a while to drain.

As long as you top up with a better spec oil...all will be ok :thumb2
