MX5Ireland

Hi all, bought a mk1 1991 mx5 about two weeks ago now and am not that fimiliar with them yet, got working on it yesterday and have replaced the clutch on it, I have the gearbox oil drained and was wondering whats the best oil for them and how much do they take??
Thanks in advance

1 ltr approx .Use good quality synthetic gear oil if possible but standard gear oil like 85/90 works fine either way . Open the fill plud on side of box and fill it until it runs out.Also very small amount of any ludbricating oil in turret ( in gear lever hole)as it does not mix with the gear oil.Its only for oiling gear linkage.

2l for gearbox? ~300ml turret? Correct me if I'm wrong!

Castrol 75W90 GL4 is very popular and works well with mx5 transmissions. Any haulfrauds should have it.

cheers lads for the advice. took just under 2L to fill the box, shes back on the road now.

Good to hear! Enjoy the weather!

I use pump on 20ltr tin so I just fill to overflow so never exactly sure how much goes in.Once it flows out that good enough for me !!

How do You add the extra oil for an NB 6 speed. I mean the small amount oil You add from the top for the 5 speed? Thx in advance for advice!

6 speed transmission share same oil for turret and the gearbox so by topping it up from the top would fill it up. 5 speed ones gearbox and turret oil is separate. Make sure not to overfill it. 6 speed takes 2l.

THX !
