From one million miles over-the-road to 20,000 hours off-highway, the technology in Schaeffer Oil extends engine life and oil life. The dream of a million miles without a major overhaul is a reality with the technology in Schaeffer Oil. To date, there are over 30 members of the Million Mile Club.
Butch Maciewski, Wayne Transport, Rosemount, MN
Petroleum hauler Butch Maciewski was issued this 1993 - 9200 International powered with a Cummins L10, 330 hp engine when it was brand new. He purchased it for his own use at 284,000 miles and converted it to Schaeffer's 7000 15W40 motor oil, #274 Moly EP Synthetic Blend Grease and #167 and #742 Gear Lubes. Butch also runs his PTO with Schaeffer HTC Hydraulic fluid.
In addition to its 1,000,000+ road miles with the engine running 1900 RPMs at a speed of 70 MPH, this tractor has many stationary engine hours of pumping product at bulk plants in cold Midwestern states. It's no wonder that during a discussion about the truck's future, a Cummins NPower overhaul supervisor was surprised that Butch was still running an engine that was only rated for 700,000 miles. The only updates to his engine were new rods and mains due to scoring from a head gasket coolant leak at 500,000 miles.
Mike Cicero, Dirt Road Xxpress, Fayetteville, AR
When Mike Cicero watched his custom 2001 Peterbilt 379 come off the line, he knew he was going to protect his investment with Schaeffer's Specialized Lubricants. Six years and over a million hard miles later, Mike proudly confesses that Schaeffer's is the reason he can stay in business. "The cost of doing business today can mean the difference between profit or loss," Mike said. He uses Schaeffer products on every moving part because it makes them last. "I use their (Diesel Treat 2000) fuel additive, motor oil, radiator treatment and greases. And after a million miles, the only things I've had to replace were three fan belts." Mike figures the fuel economy alone from Diesel Treat has given him a 1/2 mile per gallon more or 84,500 miles of free fuel. When he decided that a million miles on his fuel injectors were enough, he invited us in to take a closer look at their success. With new injectors, Mike says there's no doubt in his mind that the truck will go another million miles.
