TRUEGARD SEMI SYNTHETIC 15W/40 combines premium base stocks with next-generation additive technology to produce our most fuel efficient cleanest burning, low-ash heavy duty engine oil to date¹. It meets or exceeds nearly all the next generation OEM specifications including those from Ford, Cummins, Detroit Diesel, Mack, Volvo, Renault, Mercedes, MAN and Deutz.


TRUEGARD SEMI SYNTHETIC 15W/40 motor oils protect engines with Emission Controls, EGR engines, as well as older engines. It is even recommended by leading heavy equipment manufacturers such as John Deere, Kubota, Massey Ferguson, JJ Case, Allis Chalmers, and International Harvester. This ground breaking low-ash technology provides improved wear protection, deposit and soot control, and improves oil consumption by neutralizing combustion by-products that cause harmful deposits¹.


TRUEGARD SEMI SYNTHETIC 15W/40 is an extended drain capable engine oil that prevents viscosity loss from shearing and reduces friction leading to longer engine life and improved fuel economy¹. Its high film strength makes TRUEGARD SEMI SYNTHETIC 15W/40 fluids suitable for both on and off-road driving conditions. It can be recommended for new engines requiring CK-4 fluid and is backward
compatible with API CK-4, CJ-4, CI-4 PLUS, CI-4, and CH oils.

 

Frequently asked questions

Find answers to common questions about our products and services
  • On-highway, it meets or exceeds OEM specifications from Ford, Cummins, Detroit Diesel, Mack, Volvo, Renault, Mercedes, MAN, and Deutz. For off-road and agricultural equipment, it is recommended by John Deere, Kubota, Massey Ferguson, JJ Case, Allis Chalmers, and International Harvester, making it a single solution for mixed fleets.

  • Semi-synthetic means this oil blends premium conventional base stocks with synthetic components and next-generation additive technology, delivering better fuel efficiency, cleaner combustion, and improved wear protection than a fully conventional 15W-40 while typically remaining more cost-effective than a full synthetic.

  • Yes. While it meets the current API CK-4 specification, it is fully backward compatible with CJ-4, CI-4 PLUS, CI-4, and CH oils, so it can be used as a direct drop-in replacement in engines previously filled with any of those older service categories without requiring a special flush.

  • Low-ash formulas produce fewer solid combustion by-products, which helps protect diesel particulate filters (DPFs) and other aftertreatment components from clogging. The product specifically states it neutralizes combustion by-products that cause harmful deposits, making it appropriate for modern EGR-equipped engines as well as older engines without such systems.

  • Extended drain capability means the oil is formulated to resist viscosity loss caused by mechanical shearing and to maintain its protective properties over longer service intervals than standard oils, potentially reducing how frequently oil changes are needed. Always consult your engine manufacturer's drain interval guidelines, as OEM recommendations vary.

  • Yes. The product's high film strength is specifically cited as making it suitable for both on-road and off-road driving conditions, supporting its use across trucking fleets, construction equipment, and agricultural machinery in a single bulk drum.
