Chevron Delo 400 API CK-4, FA-4 Heavy-Duty Engine Oils with ISOSYN Advanced Technology

December 2, 2016

Chevron is releasing its line of Delo 400 API CK-4 and FA-4 heavy-duty engine oils (HDEO), engineered from the company’s proprietary ISOSYN engine oil formulation, called ISOSYN Advanced Technology.

According to Chevron, the line offers up to 68 percent better wear protection, 46 percent better piston deposit control, and 35 percent better oxidation control, all relative to the test limits set for the prior generation of HDEOs. During a 4-year development phase, the products have been tested in over 950 engines across a range of on- and off-highway vehicles, including tractor-trailers, cement mixers, diesel pickups, wheel loaders, crawler dozers, excavators, and haul trucks.
