Gear Oil

Quick notes on gear oil...

What I use is Castrol MTX SAE 75W/80.

The Haynes manual says to use SAE 30 motor oil.

Motor oil and gear box oil both have SAE numbers but the mean different things for oil types.

SAE 75W/80 gear oil is equivalent to SAE 10W/30 motor oil (as stated on the back of the Castrol MTX box). Also stated is suited to two-stroke, this and wet clutches are important for Vespas.
