Elf Scooter 4 Power 0W-30

Worth knowing

The phrases about very low viscosity when cold and fast build-up of oil pressure are word for word the same in the data sheets for Scooter 4 Power 0W-30 and 10W-30, and no figures back the claim up: the viscosity index and pour point rows are empty in both tables. So the only evidence in these data sheets for a cold-weather difference between 0W and 10W is the SAE grade. At 100 °C both oils sit within SAE 30, at 10.9 and 10.6 mm²/s; at 40 °C the 0W-30 is thinner, 55 against 70 mm²/s. They share API SP and JASO MB, so the choice between these two cans comes down to the viscosity in the scooter’s manual.

Elf Scooter 4 Power 5W-40 is a different case: the classes are the same, but 13.7 mm²/s at 100 °C already belongs to SAE 40, and the shared line name does not change that. What an engine risks on an oil thinner than the manufacturer specifies is covered in a separate article. The data sheet mentions HTHS among the factors protecting the piston but prints no value, so the table offers nothing to compare.
