SAE 10W-40
10W-40 is the broadest-use grade in the ASAS range: it appears in the petrol, diesel and four-stroke motorcycle lines. The 40 high-temperature rating gives a thicker film than a 20-weight oil at operating temperature, which is why it is common in warm climates and in engines that see sustained load.
