- Buyer's Guide
AMSOIL Inc. of Superior, Wis., recently upgraded a line of its Synthetic Diesel Oil for extended service life highlighting documented fuel efficiency benefits. This premium diesel oil for model year 2007 and newer heavy-duty and pickup truck diesel engines requiring API CJ-4 emission quality oil standards delivers extraordinary lubrication in diesel engines found in commercial, fleet and personal vehicles.
Formulated with the latest additive technology and the most advanced synthetic base oils, AMSOIL Premium API CJ-4 Synthetic 5W-40 Diesel Oil exceeds the higher performance demands of modern engines. This fuel efficient formula withstands the stress of heat, soot and acids to help prevent deposits, corrosion and wear, and its broad viscosity range offers superior protection over a wide temperature range.
Measurable Environmental Benefits
AMSOIL 5W-40 Premium Synthetic Diesel Oil provides improved fuel economy up to 3 percent, or an average of 1.6 percent (55 percent city, 45 percent highway). Combined with the extended service, the new oil reduces packaging waste and waste oil disposal by three-fold, as well as downtime for maintenance.
AMSOIL Synthetic 5W-40 Diesel Oil resists breakdown and is recommended for three times the original equipment manufacturer (OEM) oil drain interval, not to exceed 50,000 miles per 600 hours, or one year. Significant costs savings can be achieved using this extended drain interval product over conventional petroleum based products. Drain intervals may be extended further when monitored by oil analysis. The new oil is compatible with all exhaust treatment devices and its low sulfated ash formula is designed to extend the service life of diesel particulate filters.
