JMC Engine Oil 100% Synthetic (4 litres)
100% synthetic oil, for all 4-stroke motocycle engines.
Index 10W40 or 10W50 (depending on supply), Triumph recommends either for all of its bikes in temperate climates.
4-litre can, more than enough for an oil change on all motorcycles.
Compared with well-known brands of oil, JMC's motor oil is like a generic drug, the active components are the same (the "base oils" sold wholesale by major oil companies), the difference is mainly in secondary components and the marketing efforts of brands, that someone has to pay!
JMC Motor Oil is a quality white-label oil used by many professionals in Germany.
