In our test with the Phillips syn blend with titanium with a local trucking company thier truck at a short service on delo was using 1.5 gal of oil and on the full service cycle another 1.5 gallons. A total of 3 gallons in 22k miles. With the Phillips, on a short service, the truck used .5 quarts and 1.5 QUARTS during the 22k mile interval. Big difference. We did 3 tests, until the driver rolled the truck ending the testing, but it was getting better each time. ConocoPhillips Lubricants: World-class products and services
