AMSOIL OE 15W-40 Synthetic Diesel Oil is a budget-priced synthetic designed to stay in service for the longest drain intervals that your OEM has to offer and delivers steadfast protection every step of the way. Best of all, it carries the latest API CJ-4 specification, so your warranty is safe. OE 15W-40 is suitable for medium and heavy-duty diesel engines of all model years where a 15W-40 is desired.

Compatible with Modern Diesel Exhaust Treatment Devices

This API CJ-4 15W-40 synthetic diesel engine oil is compatible with all late-model exhaust treatment units including diesel particulate filters.

All Climate Protection

AMSOIL OE 15W-40’s synthetic formula offers something that most regular diesel 15W-40 engine oils can’t, and that is performance and protection at both ends of the temperature spectrum. This OE 15W-40 diesel oil resists thinning and oil burning at high temperatures under heavy loads. In winter, the -38C (-36F) pour point delivers protection and easy starting on cold mornings.

Controls Oil Usage

The hallmark of a good synthetic oil is its ability to resist oil usage during periods of extreme heat and heavy loads. AMSOIL OE 15W-40 synthetic oil keeps the oil level steady and does not thicken after hard use and long hours.

Fights Soot Formation

Soot can be a major contributor to wear in diesel engines. It can cause the engine oil to thicken and can also increase engine wear. AMSOIL OE 15W-40 Synthetic Diesel Oils contains detergents and dispersants that keep soot in suspension and your diesel engine internals clean.
