Speedco used to be a lube and oil change company that specialized in doing OTR truck maintenance. They are located right beside truck stops usually. Loves bought out the company (I think it was Loves) and now they still do what hey did before, but have Loves products at them. They have Luber-Finer and Fleetguard oil filters and many sites will do diesel motocoaches (some do and some don't so call ahead). They are quick and efficient and usually much less costly than getting service from a Detroit Diesel or other service center. I get 53 quarts of Rotella or now their own oil and complete lube and all new oil filters and a computer analysis of the removed oil for right around $400.
Speedco has done all the oil changes and Lubes for all three of my coaches.... always done a nice job at a reasonable cost.
Just Google Speedco and you can get a map of their national locations.... usually right beside a major truckstop and right beside a major interstate.
