Frequently Asked Questions (FAQs)

Q: Why should I buy Traveller lubricants?

A: Tractor Supply Company works very hard to provide very high-quality, technologically advanced lubricants that are specifically formulated with balanced chemistry. This comes together in an outstanding product selection designed to give your customers' equipment enhanced oxidation, exceptional deposit and wear control, outstanding ability to handle soot and, in the end, prolonged engine life.

Q: Who makes Traveller Lubricants?

A: Warren Distribution (since 1922) is based in Omaha, Nebraska and has been Tractor Supply Company's supplier of lubricant products since 1997. As a large, privately owned independent oil company, Warren blends and packages private-label oils for major brands in the market, including retailers, the Department of the Defense and other agricultural brands, including Traveller.

Warren purchases the highest-quality severely hydrotreated base oils available from the world's major refiners and combines them with the most technologically advanced additive systems, resulting in finished lubricants that meet or exceed OEM requirements. Warren Distribution is fully licensed and approved by the American Petroleum Institute.

Q: Is Traveller Fleet Heavy Duty Diesel Engine oil approved for use in a gasoline engine?

A: According to the API service classification, these products meet or exceed the performance requirements for API Service CI-4/SL. The "SL" classification indicates these engine oils can be used in gasoline engines. But remember: Always refer to the automobile's Owner's Manual for the preferred SAE grade.

Q: Is Traveller Universal Tractor Fluid compatible with other brands of tractor fluid?

A: Yes, they are fully compatible with every other brand -- although not all other brands meet the same high quality standards set by Tractor Supply Company.

Q: Do Synthetic Oil or Synthetic Oil Blends last any longer than do regular mineral oil formulations?

A: No, Synthetics require oil changes at the same oil drain interval as do regular mineral oil formulations. Here's why: "Synthetic" refers to the base oil used, which is just one part of the formulation. The additive system used with the base synthetic oil is identical to that used in regular mineral oil formulations. These additives deplete at the same rate during engine combustion, whether in a synthetic or a regular oil. The base oils never wear out but they do become contaminated with combustion by-products when doing their job protecting the engine.

Q: Why does Traveller Fleet Heavy Duty SAE 15W40 perform better than straight 30 weight?

A: 15W40 pumps much quicker during engine start-up and flows slower at high operating temperatures. Since approximately 50% of engine wear occurs at start-up and 15W40 pumps quicker to the valves, you get improved protection. In addition, at higher operating temperatures, 15W40 flows slower, leaving a thicker oil film between parts. This film offers a better level of protection. Finally, 15W40 helps lower oil consumption by improved wiping of the cylinder walls - this means less "burn-off" and lower emissions.

Q: Can Traveller Universal Tractor Fluid be used where Allison Type C-4 and Cat TO-2 fluids are recommended?

A: Yes, Traveller Universal Tractor Fluid meets or exceeds all the requirements for transmissions requiring Allison Type C-4 and Caterpillar TO-2 lubricant specifications, meaning this fluid is appropriate for a wide range of applications.

Q: What is the weight of Traveller Universal Tractor Fluid?

A: Traveller Universal Tractor Fluid is actually 10W20 multi-viscosity weight oil that has 10-weight pumpability (viscosity) when it's cold, and a 20-weight pumpability during normal operating temperatures.

Q: What about the use of aftermarket oil additives sold under various private labels?

A: Tractor Supply Company specifically recommends not using oil additives and, in fact, the use of additives may adversely affect your customer's machinery warranty. After the warranty period expires, however, there is nothing to prevent a customer's using any number of additives. However, your customers need to realize that our oils already include the proper balance of additives as specified by OEM engineers; this additive package has been designed to protect their equipments' engines. At worst, the addition of aftermarket additives may disturb this fine balance and, at best, are unnecessary.

However, there is generally more to be lost than gained by using aftermarket oil additives. Many oil additives contain PTFE, also known as Teflon. PTFE is a solid. The job of your engine's oil filter is to collect solid particles down to about 10 microns in size. That size means that the much larger PTFE particles will end up in the filter, plugging the filter and causing the bypass valve to open, allowing the engine to run on unfiltered oil. And that's really asking for trouble!

Other additives are nothing but ultra-thick substances that increase the oil's viscosity in an attempt to reduce leaking from a seal that has seen better days. Your customer would be better off to change the seal: Attempting to stop a leaking seal by thickening the oil can't be good for an engine that is not leaking or burning oil.

Some oil additives contain real anti-wear additives such as ZDDP (Zinc). ZDDP is a useful additive when used in the right concentration, and in the right combination with other additives. Good diesel motor oils already contain the right amount of ZDDP along with other additives that come together in a well-engineered, balanced additive package. This is the type of additive package already formulated into Traveller lubricants.
