Chevron unveiled its new line of Delo 400 engine oils meeting the American Petroleum Institute’s new CK-4 and FA-4 heavy-duty diesel oil specifications, offering improvements in fuel economy and engine protection.
These new API specifications, which go into effect Dec. 1, were requested by engine makers to help them protect modern engines while improving fuel economy. FA-4 engine oils are designed to provide optimized fuel economy and protection for the newest engines. CK-4 engine oils are backward-compatible but provide better protection for current engines than the previous CJ-4 category.
Shawn Whitacre, Chevron senior staff engineer and chairman of the ASTM Heavy-Duty Engine Oil Classification Panel, called the rollout “one of the most significant new product introductions in our history, and the most extensive laboratory development program we’ve ever developed.
“On top of the very significant laboratory test program, we’ve added to what I would say is the most rigorous, varied and exhaustive field testing program we’ve ever undertaken.” The new oils have been testing in close to 500 Class 8 trucks, as well as a broad variety of off-highway equipment such as cement mixers, construction equipment, mining and agricultural equipment.
The oils feature what Chevron is calling Isosyn Advanced Technology, a combination of Chevron’t premium base oils, formulation expertise and additive chemistry. Officials note that Chevron is unusual in that it has its own company making the chemical additives necessary for engine oils today. (In fact, Chevron says, it was the first company to start adding chemicals to base oils back during WWII, allowing submarines to run longer between maintenance.)
Chevron says the Isosyn Advanced Technology enables increased durability, through better oxidation control, anti-wear protection and piston control, while extending drain intervals compared to API CJ-4 oils.
“We are seeing some of the longest drain intervals and best engine protection in our company history,” said …Read the rest of this story
