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. More info to come before going up on the main page. |
