It wasn't long before Chestien was forced to hire a salesman so he could devote his time to producing and bottling. However, just as business was beginning to pick up, World War II began. The Salesman went into the Navy and Chestien Wynn could no longer get the chemicals and lubricants to make his product

WWII ENDS. Production resumes.

Son Carl E. Wynn joins the company and moves production into his two car garage. On May 28, 1947 the company was incorporated under the name Wynn Oil Company at 1222 Duarte Road, San Gabriel, California. An average of 40 cases of products per day was produced.

April 1, 1948, Fire destroyed the two car garage. Within a few short weeks Wynn's actually flew in equipment and machinery to resume operation in a temporary location at Azusa, California.A flight was made in a Luscombe Silvaire airplane with NO OIL IN THE CRANKCASE. The plane flew seven minutes without oil (the engine had been treated with Wynn's Friction Proofing, illustrating that it penetrates the surfaces of moving metal parts and forms a protective film of lubrication).

The Deep Sea Test was run in Newport Beach, CA in June. Two motors were immersed into salt water and left for fourteen days. One of the motors was treated with Wynn's Friction Proofing Oil and the other was not.RESULTS: While still wet, the motor treated with Friction Proofing started without difficulty, the other did not.

Year long Twin Car tests were conducted to demonstrate that the product reduces wear and fuel consumption over a 100,000 mile test period. Independent consultants certified the accuracy of the test which showed that Wynn's Friction Proofing products were responsible for 10.1% better gas mileage and 44.7% less bearing damage and 21.6% less starting friction.

The establishment of a new world's land speed record in 1957 on the Bonnesville Salt Flats by the Wynn's Friction Proofing "Streamliner" continued the company's high performance publicity. Driven by Roy Leslie (a distributor) the sleek car, powered by three tandem engines, travelled more than 435 km/h (270 mph) to reach the best one-mile land speed ever obtained.

Wynn's Belgium was established in 1958 at Sint-Niklaas in Belgium. The main activity of the company is the production and export of the Wynn's product range in Western and Eastern Europe, Africa, the Middle East and India.At present the total surface is more than 8.000 m² in which a well equipped production facility, a warehouse, a research and development lab and administration are situated.Wynn's Belgium manufactures more than 400 product references for cars. The research and development department plays a key role. Highly qualified personnel develop new products to meet the needs of the European, Middle Eastern and African markets.

Two new records for light plane endurance flights are set. The first at 1200 hours and the second at 1650 hours, were set consecutively in aircraft protected by Wynn's Friction Proofing. "Old Scotchman", a Cessna based in Dallas, Texas, set the 50-day, 1200 hour mark. The "Hacienda" of Las Vegas, Nevada, set a new record of 64 days, 22 hours, and 19 minutes. Federal aviation authorities certified Wynn's products for use in light aircraft.

Wynn's products are feature in Jerry Lewis' movie "The Family Jewels". Johnny Cash races in Lake Havasu Boat races in the Wynn's "Ring of Fire".

Don Garlits, superstar of the developing sport of drag racing, learned that his powerful dragster's engine was protected against piston scuffing when Wynn's was used. His voluntary use of Wynn's led to company sponsorship of his car, an association which was to last many years.

In 1972 Wynn's products were used by NASA on lunar missions to protect critical equipment in extreme heat and cold.

In 1995 Wynn's Belgium obtained the ISO 9001 certificate. As a result, the quality system is kept up to standard, costs and efficiency are under control, as well as the quality level of products and processes.

In September 1997 Wynn's European Technical Training Centre was operational for training sessions, organised for customers as well as for the sales and marketing people of distributors and subsidiaries.The commercial strategy of Wynn's Belgium concentrates on the export, representing more than 96 % of its total turnover. Wynn's Belgium faces a big challenge and they are presently cooperating with more than 90 distributors in more than 65 countries in Europe, the Middle East and Africa.
