Sold under the Guardol and Kendall names, ConocoPhillips’ premium synthetic blend CJ-4 heavy duty engine oil has been reformulated with a proprietary additive called “Liquid Titanium” that the company said improves engine-wear and bearing-corrosion protection as well as increases oxidation stability.
Guardol ECT and Kendall Super-D XA are the only multi-grade HD oils offered with the liquid titanium additive, which ConocoPhillips said chemically binds with engine parts to reduce wear and extend engine life. Not available as an aftermarket additive, the liquid titanium is completely soluble in the lubricant and contains no solids or material in suspension, the company said.
In the severe Cummins ISB test for HD oils, the new ConocoPhillips products showed significant wear reductions in valve train components compared to previous versions of Guardol EXT and Kendall Super-D XA oil, according to Steve Tarbox, ConocoPhillips director of product management. Other standard oil-industry tests for HD diesel engines also showed decreased bearing corrosion and longer oxidation life for the new oil. Those three performance improvements offer users the potential to lower engine maintenance and repair costs, extend oil life and improve engine performance, especially in severe applications, Tarbox said.
Meeting API CJ-4 requirements, the new ConocoPhillips synthetic-blend oils with liquid titanium are approved for use with all diesels meeting the 2007 emissions requirements and are backward-compatible with older engines.
Guardol ECT with Liquid Titanium, which is sold under the Conoco, Phillips 66 and 76 Lubricants brand names, and Kendall Super-D XA with Liquid Titanium are available in quart and 1-gal. jugs, as well as in drums and bulk shipments.
