Premium API CJ-4 5W & 15W-40 Synthetic Diesel Oil

Maximum Fuel Economy and Extended Drain Intervals in Ultra-Low Emission Diesel Engines

Amsoil 15W-40 CJ4 Synthetic Diesel OilPremium choice diesel oil for model-year 2007 and newer diesel engines requiring API CJ-4 emission quality oil standards. Also recommended for pre-2007 diesel engines. Incredibly shear-stable to withstand the stress of heat, soot and acids and help prevent deposits, corrosion and wear. Broad viscosity range offers superior protection over a wide temperature range. Effectively resists oil consumption and emmissions, while improving fuel efficiency. Recommended for up to three times the original equipment manufacturer's drain interval recommendation in diesel applications, not to exceed 50,000 miles/600 hours or one year, whichever comes first.* Recommended for up to two times the original equipment manufacturer's drain interval recommendation in gasoline applications, not to exceed 15,ooo miles or one year, whichever comes first. Compatible with all exhaust treatment devices and designed to extend the service life of particulate filters.

*Due to fuel dilution issues, extended drain intervals are not recommended for 2007-2009 Caterpillar C13 and C15 on-highway engines or 2007-present Dodge, Ford and GM light-duty diesel pick-ups.

AMSOIL, the leader in automotive synthetic lubrication, produced the world's first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics®, to do the best job protecting your engine.

Meets Emission System Requirements
AMSOIL 5W-40 Synthetic Diesel Oil is a low-sulfated ash formulation that ex­ ceeds the requirements for low-emission quality diesel oil. It is compatible with all exhaust treatment devices and is designed to extend the service life of diesel particulate filters (DPF).

Extended Drain Performance
AMSOIL Premium 5W-40 & 15W-40 Diesel Oil can extend drain intervals far beyond those recommended for conventional petroleum oils. Its unique synthetic formulation and long-drain additive system (10.4 TBN) deliver superior engine protection, cleanliness and performance over extended drain in­ tervals. AMSOIL 5W-40 & 15W-40 Synthetic Diesel Oil provides maximum protection for up to 3X the OEM-recommended drain interval and even further with oil analysis. As seen in the graphs, AMSOIL Premium Diesel Oil provided both superior TBN and viscosity reten­ tion over 400 hours of severe-service operation.

Improves Fuel Economy
The advanced synthetic technology used to engineer AMSOIL Premium 5W-40 & 15W-40 Diesel Oil enhances viscosity properties and are proven to deliver better fuel economy. In fact, the Environmental Protection Agency's (EPA) Federal Test Procedure confirms that AMSOIL 5W-40 & 15W-40 Diesel Oil provides up to 3 percent better fuel economy than conventional 15W-40 diesel oils. At a mix of 55 percent city/45 percent highway driving, the average improvement is 1.6 percent and at straight highway driving the average improvement is 1.25 percent.

Minimizes Oil Consumption and Emissions
Due to its low rate of volatility (burn-off), AMSOIL 5W-40 & 15W-40 Synthetic Diesel Oil are able to reduce oil consumption and emissions dur­ ing operation. Lower volatility helps AMSOIL Premium Diesel Oil retain its viscosity after high-temperature service for dependable protection and excellent fuel economy.

COMPATIBILITY
AMSOIL 5W-40 & 15W-40 Synthetic Diesel Oil are compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

SERVICE LIFE
AMSOIL Premium CJ-4 5W-40 & 15W-40 Synthetic Diesel Oil are recommended for extended drain intervals in engines that are unmodified and in good operating condition.

Diesel Engine Service

  • Three times (3X) OEM* recommendation, not to exceed 15,000 miles or one year, whichever comes first.

*Operating conditions and drain intervals for normal and severe service are defined by the OEM. Refer to your owner’s manual.

Note: Extended drain intervals are not recommended when using biofuels containing >10% ethanol or 5% biodiesel (B5). Follow OEM drain intervals or extend drain intervals with oil analysis.
