Technical Uno 60 1988 - Gear oil

[luiguiv]

Hello everyone, hoping you're doing well.

Quick question: which gear oil should I use for a Uno 1988 1116cc 5 gear boc? Haynes service manual says ZC 90 would be the one. Will either 80w90 or 15w40 be a proper equivalente spec for ZC 90?

Thanks for your time,

ZC90 is an SAE 80W-90 Oil, API GL3 Oil

See attached spec

Some people have used 20W-50 engine oil with supposedly good results and a less notch y gear operation.

If you want to go with "offical" then an SAE 80W-90 Oil, API GL3 Oil should be your choice.

Later Fiat gearboxes use ZC80/S (Tipo / Tempra) and ZC75 Synthetic (SAE 75W-80, GL5, Barchetta, Punto HGT)
