AMSOIL Max-Duty Diesel 15W-40 engine oil (DME)

AMSOIL Lubricant – Signature Series 15W-40 (DME)
AMSOIL oils and additives – lubrication is the last place to compromise.

Amsoil is a US-based lubricant manufacturer known for maintaining extremely high quality standards without the cost-cutting measures that have affected many traditional oil brands. The focus is purely on lubrication performance and engine durability.

In our own workshop projects Amsoil is often a requirement, not just a recommendation. A quality oil is the cheapest insurance you can buy for a tuned or heavily loaded engine.

What should you know about this product?

Signature Series Max-Duty is AMSOIL’s strongest weapon for heavy-duty commercial and utility diesel engines. It uses the best synthetic raw materials and has naturally high resistance to oxidation. A generous amount of detergent and dispersant additives prevents soot from forming large, abrasive, and wear-causing particles. The oil is extremely thermally stable, maintains its viscosity in hot conditions, and flows excellently in sub-zero temperatures. It has low volatility (burn-off), resulting in up to 76% less oil consumption than required by the API CK-4 standard. Protection against wear on cylinder liners and piston rings is 6 times better compared to the requirement of the DFS 93K222 test (Detroit Diesel DD13 Scuffing Test).
