Rislone Motorsport

Rislone®

Founded in 1921 by the Shaler Company, Rislone was one of the original automotive chemical additives.

The machining tolerances for early automobiles were not what they are today. Subsequently, one of the major problems was improper piston ring seating. Engines often had to be torn down every 2,000 to 3,000 miles and re-ringed.


Rislone was originally sold in glass bottles through service stations along with Shaler Hot Patches, a vulcanizing system for tire repair. In the 1930s, Shaler built product awareness by combining showmanship and salesmanship with the Shaler Traveling Circus.


Along with the engine performance benefits, Rislone was instrumental in coining one of the most common phrases in automotive vernacular: the Tune-up. In the late 1930s, Shaler developed a training system for mechanics called the Shaler Rislone Tune-Up System. The benefits of a Tune-Up to both customer and service provider were numerous. By enhancing a regular oil change with the addition of Rislone and Karbout, a Shaler product for cleaning carburetors, the mechanic was able to guarantee the customer "Feel-able Improvement" in the car’s performance. Locations that followed the system were designated as "Authorized Tune-Up Service Stations.”


During the 1940s and 50s, Rislone was offering a "Money-Back Guarantee of Smooth-Driving Satisfaction." Advertisements in publications such as Life and The Saturday Evening Post challenged drivers to add Rislone during an oil change, and then drive 10 miles. If the beneficial effects of the additive were not felt within 10 miles, they could return to the dealer for a full refund. Of the more than 20 million guarantee cards issued with the purchase of Rislone, fewer than one half of one percent were returned for a refund.
