Elf Scooter 4 Maxi City 5W-40

Worth knowing

Of the seven four-stroke oils in the Elf Scooter range, only this one has no JASO class: the other six have JASO MB, while this data sheet stops at API SL. When the scooter’s manual names a JASO class, this can does not confirm it. At the same 5W-40, Elf Scooter 4 Power 5W-40 has class MB and Moto 4 Racer 5W-40 has MA2, both with API SP as well. At 100 °C the figures for all three are close: 14.3 mm²/s here, 13.7 and 13.8 mm²/s for the other two, so the declared classes, not viscosity, decide between them.

The Elf catalogue page aims the oil at all modern small and large four-stroke scooters, whereas API assigns SL to engines of model year 2004 and older, so the line in the manual decides. SL covers a requirement for SJ or earlier classes; if the manual lists a newer class, SP for example, this oil does not meet it. There is more in the article on API SL. The data sheet also reminds you of the change intervals and minimum viscosity set by the scooter’s manufacturer.
