My 1995 ford fiesta 1.6 lists sae80 for gearbox oil which seems to be mineral stuff.
Can i use synthetic 75w80 or will it blow up?
My logic is that if its a 80 when hot then it should be fine and thinner than the straight 80 when cold.
But not sure if gearboxs are more sensitive to oil than engines are?
