10W-30 Delo hits 70K mile drain interval

This week, Chevron Products Company released a case study highlighting the performance of Delo 400 LE SAE 10W-30 formulated with ISOSYN Technology and Delo Extended Life Coolant (ELC) at R.E. West Transportation.

The report says, by using Delo products, R.E. West was able to extend service intervals and improve fuel economy, resulting in cost savings for the company.

R.E. West is a national contract and dedicated truckload carrier with a fleet of 120 trucks and 300 trailers. The company conducted a test using Chevron’s lower-viscosity Delo 400 LE SAE 10W-30 engine oil in an effort to evaluate the feasibility of switching its fleet to the fuel economy-focused product, while also extending drain intervals.

After comparing data, R.E. West found the trucks running Delo 400 LE SAE 10W-30 delivered noticeable fuel economy improvements versus similar trucks using SAE 15W-40 oil.

Beyond improvements in fuel economy, R.E. West says it achieved 70,000 mile oil drain intervals using the Delo 400 SAE 10W-30 engine oils.

“I’ve looked at the data off of this truck compared to all our other trucks in our fleet, and this truck using the 10W-30 gets over 2 percent better fuel mileage,” R.E. West Maintenance Manager Dustin Stricker says. 

“[It’s] $5,400 a year less for this truck to run down the road with $3.75/G fuel,” company founder Bob West says.

After one of the Detroit Diesel DD15 engine used in the testing was torn down at 500,000 miles of service, R.E. West found its components to be in excellent condition with minimal wear.
