New Engines Require Oil to Work Harder

s the Environmental Protection Agency continues to tighten its pollution standards for diesel truck engines, manufacturers are similarly increasing the demands they place on oil companies for lubricants that can protect sophisticated vehicle power plants that run at higher temperatures.

No sooner than cooled exhaust gas recirculation and other technologies were placed in October 2002 engines, the major manufacturers began looking to install different new systems in their 2007 model-year products in order to comply with a new tier of regulations.

While many of the 2007-year model engines are still on the drawing board, when the stricter EPA rules kick in, there are going to be more demands placed on lube oils, according to those involved with developing the lubricants and the standards that govern their use.
