Vespa P range and LML Star 2T models require 250ml of SAE 30 engine oil or SAE 80W gear oil.9 u" d. B7 x4 C3 _

' i) V& J0 _( x u/ c/ |$ U" J C3 `Piaggio recommend a first gearbox oil change at 3000 miles (5000 km) and then every 6000 miles (10000 km), however we would recommend changing the oil every 3000 miles (5000 km) on a standard engine and 1500 miles (2500 km) on a tuned engine. It is not a break down in the gearbox oil that is the problem but the amount of fine metal particals from the gearbox that build up in the oil. We recommend using a magnetic oil drain plug to remove the metal particals from the oil.* v S, s9 e. H+ Q: i" J- o, Q: t

When the Vespa P range was launched in 1977 Piaggio's recommended gearbox oil was 2 stroke oil with a SAE 40 viscosity. This was later changed to SAE 30 engine oil. In 1995 Piaggio changed the clutch on the Vespa P range and recommended SAE 80W gear oil for use in the gearbox.( s5 U- @* H6 c# l; w* X

Engine and gear oils are made in a similar way using a mineral or synthetic base oil blended with additive packs to reach a minimum specification. For example API (American Petrolium Institue) specifications are widely used. Engine oils usually having 2 specifications, S for spark ignition engines (petrol) and C for compression ignition engines (diesel) followed by a letter. The higher the second letter, the later the specification. Similarly gear oils have a GL- rating although this is followed by a number and it is not the case that the higher the number the later the specification and an API GL-4 gear oil is required for the Vespa / LML gearbox.* x' q- N; Z& w/ T3 d!

The SAE grade is the oils viscosity at a certain temperature and the W stands for Winter (not weight) meaning its viscosity at low temperatures. At 100°C the viscosity of SAE 30 engine oil is similar to SAE 80W gear oil. |
