Purpose and Specifications

MOTUL TEKMA MEGA X 15W40 5L is a premium Technosynthese semi-synthetic diesel engine oil built for heavy-duty trucks, bulldozers, construction equipment, buses, farm machinery, stationary engines, and boats. This 15W-40 viscosity oil flows smoothly in cold starts down to -20°C and stays thick under extreme heat up to 228°C flash point, protecting turbocharged or naturally aspirated engines from wear, soot buildup, and corrosion even with high-sulfur fuels over 0.5%.

It meets top specs like VOLVO VDS-3, MAN M3477, API CI-4/CH-4, CUMMINS CES 20071-20078, making it perfect for mixed fleets of Euro II-V engines with EGR or SCR. Superior detergents keep pistons clean, reduce fuel use, and prevent oil filter clogs for reliable performance in mining, quarrying, and off-road work.

When to Use / Replace?

Use in severe conditions like construction sites or long-haul trucking where engines face high soot and heat. Replace every 30,000-60,000 km or 12-24 months per manufacturer guidelines, adjusting for fuel sulfur and duty cycle - this oil's high TBN (acid-neutralizing reserve) supports extended drains without risking engine life. Shelf life is 5 years unopened in cool, dry storage.

Compatible with mineral or synthetic oils for easy top-ups.

FAQ

Is MOTUL TEKMA MEGA X 15W40 safe for older diesel engines?
Yes, it protects both new low-emission (Euro II-V) and older engines, handling EGR/SCR systems while preventing bore polishing and deposits.

Can I use it in high-sulfur fuel areas?
Absolutely - designed for fuels over 0.5% sulfur, avoiding cylinder liner corrosion and extending oil life.

What if I miss the drain interval?
Its anti-oxidation additives resist breakdown, but stick to 30,000-60,000 km or 12-24 months to maintain peak protection.
