Krex History  

A Hot Issue

Over a half century ago, while the Battle of Britain flamed in the skies above London, the Royal Air Force drove their Spitfires relentlessly; no time for maintenance, less time for overhaul. Yet, the Rolls-Royce engines held up well and helped immortalize the dashing Spitfire in aviation history. That epic battle was only the beginning of the demands made on the Rolls-Royce engines built for the war effort. Not only did Rolls-Royce engines power the Spitfire but also the de Haviland Mosquito and Whirlwind fighter bombers, as well as the heavier Avro-Lancaster and Armstrong-Whitley bombers. The planes were being subjected to extended flights across the English Channel and were constantly in the air over the Continent. The 24-hour saturation bombing by the Americans and the British took its toll against the enemy but it also took its toll against the engines that powered those planes.

The war effort demanded maximum production capacity and many of these engines were, in fact, produced by the Packard Motor Company in Detroit, Michigan. During the latter half of the War, when demand for replacement engines was great, a severe problem existed at the Detroit Packard plant: a 22% reject rate. The Packard people strived to increase engine production and tried everything possible to eliminate the Green Run. This first performance run of a new engine was the most severe it would endure and verified that the engine met all specification standards. Results were consistently disheartening: an average of 22% of the engines' valve stems were scratched or pitted to the degree that they had to be rejected, removed and replaced with new valves. The failure of the valve stem was considered a lubrication problem.

Packard had contacted all the leading lubricant and petroleum companies, and for months tested their products in the Green Run performance test, studied results, and adjusted everything from viscosity to quantity but the condition persisted. Packard technical personnel were highly sensitive to the War's critical need for engines and spirits were lowered by the recurring valve failure.

The Graphite Solution

Marc Markey, founder of KREX, Inc., told the story from his retirement home in Florida, "That is when the prototype of today's KREX® Graphite Engine Lubricant appeared."

The graphite lubricant was presented to Packard for use in the Rolls-Royce engines. Ultimately, the graphite lubricant solved the Packard problem but the story of how the product was finally accepted by the Packard executives is the classic romance of invention meeting need when need loved someone else.

Markey explained, "It was shortly before that time that our small group of little-known lubrication engineers had organized a new company to produce and market graphite lubricant. We heard rumors that Packard was having serious lubrication problems. Excited at the prospects, we rushed over to the plant to offer our services and samples of our new product. We were convinced our product could withstand the exceptionally adverse conditions of heat and engine demand." Markey clearly recalled Packard's response: "No, Packard was not interested in wasting time testing a new and as-yet-unknown product ... the best talent and lubrication expertise available were already on the problem."

No doubt you can understand the disappointment these young engineers experienced, but they knew this was the ultimate test for their product. Undaunted, Markey's team persisted. They pursued the attention of the Packard Project Engineer for days and weeks; almost two months passed while valves failed, were rejected and replaced and engine production was held back. Increasing pressure to meet production demands while unable to solve the lubrication problem took its toll on project personnel; Packard relented and realized that they had nothing to lose by trying the graphite lubricant and consented to a trial test.

Trial by Fire

At last, these lubrication engineers won a chance for the optimum testing conditions for their product. The Project Engineer ordered ten engines to be treated with the graphite lubricant prior to final assembly and testing. For several days, Markey's team waited anxiously for the results of the Green Run. When the Project Engineer reported back to them, he was apologetic. "Sorry boys. Just when you want a reliable sample for testing, everything runs lucky and you can't get a good reading. Only 2% of the valve stems were damaged." Even though conditioned to a much higher failure rate, the Project Engineer remained unconvinced that this new product was responsible for the improvement but agreed to test again, this time using 25 engines. Several days later, the results were the same, only 2% failed the test. Nevertheless, the Project Engineer was still skeptical. Markey recalls, "Naturally, we were certain it was our graphite lubricant that was responsible. We were jubilant! However the Project Engineer felt that too much and too many lives depended on being accurate. He said, 'Let's try one more time.' This time the Project Engineer ordered 100 engines tested, all the valve stems were treated with the graphite lubricant. When the third test validated the earlier tests, and all our claims, he issued an order: all Rolls-Royce engines produced from that day until the end of the War were to be treated with our graphite lubricant. Under no circumstances were we to let them run out of graphite lubricant and we were on call day and night."

The Project Engineer told the Markey team that of all the items purchased by him during the War, he felt the graphite lubricant had benefited the program most. It was after the Packard operation closed that Markey's team realized the value of their experiences with Rolls-Royce engines. It was clear that the testing environment and criteria had proven their graphite lubricant was far superior to any lubricant which had been developed by any other company producing lubri- cants. They also recognized the growing need for graphite lubricant in the automotive marketplace. Since those days when the 12 and 16 cylinder engines powering the aircraft of World War II roamed the skies of Europe, KREX® Graphite Engine Lubricant has been sold exclusively through new car dealers. For 50 years, KREX Graphite Engine Lubricant remains the consummate preventive maintenance product.
