General Gearbox oil

[cnikonpete]

Is this oil ok for my 1.1 2009, haven’t got a handbook, and totally confused PETRONAS TUTELA 75W-80 SYNTHETIC MANUAL TRANSMISSION FLUID

 

[koalar]

Minimum Synthetic oil SAE 75W- 80 EP, that passes
API GL5, MIL - L - 2105 D LEV specifications.

Recommend TUTELA CAR ZC 75 SYNTH

Any SAE around 75W there's a bit of leeway and is GL5 will work fine
