What the seller commits to paper

API SN PLUS | JASO MA2. Oil type: mineral. 10W-40, 1 litre. Stated excellent for wet clutches, catalytic-converter tested, with low oil consumption, ageing stability, high shear stability and engine cleanliness.

The two classifications are the whole specification

API describes the oil’s performance against a petrol engine standard. JASO describes its friction behaviour, which is what matters when the engine oil also bathes the clutch — as it does on almost every motorcycle and on no car.

An oil that publishes both can be matched against a manual. An oil that publishes neither cannot be matched against anything, and one four-litre can in this family publishes neither.

Mineral, stated

The maker says it plainly. Mineral oil is not a lesser product; it is a shorter-lived one, and which your machine wants is in its manual rather than in a sales line.

A note on the price

The same reference is listed across six markets at prices that vary by more than three times. This site reports what it read on each; the live listing is what you pay.

Availability

Between 14 € and 20 € across the German, Italian and Spanish Amazon stores, in the single reading behind this page.

Priced in local currency, which the euro range above deliberately leaves out, it also appears on the American and British Amazon stores.

More than 1.6× what the cheapest country asked was being charged on the French Amazon store. A gap of that width usually points to goods sent in from abroad rather than a seller on the ground, so that amount stays outside the range above.
