Remember this? You Saw it in January 1954 The Jreatest Motor Spirit Its even more important than ever now 1 Development When, 3 Years ag0, we introduced LCA: our world- supreme Ignition Control Addicive (incorporating Years tricresyl phosphate)_we called it "The greatest motor 32 spirit development in 32 years Ic was a bold claim in made deliberately and res ponsibly by a Company with a world reputation for leadership and integrity: It was made with an eye to both ics present and future importance in car engines. Has it been justified 2 Let" S have a closer look SHELL L. LC.A: was the first and most complete answer to problems of ignition and spark plug fouling due to engine deposits__the major cause of power loss in cars: Solving these problems has greatly assisted the development of the modern high compression engine: 2. Shell scientists knew that, valuable as LCA: was then, ics importance would grow as the power of engines went up: This has indeed happened: Modern high compression engines, with their higher temperatures and pressures, are specially sensitive to deposits: They need LC.A: more WTR than ever to maintain correct firing and full smooth power: 3. Shell's claim was based on 5 years' research in which hundreds of different additives were tested: L.C.A: (in- corporating tricresyl phosphate) proved overwhelmingly superior. No other additive, or combination of additives, can give the same result: Shell discovered it ; Shell CONTROL ADDITIVE) proved it; Shell patented it: L.C.A: was, and still is (GNITIOEciosive to Sclunirg; Cotra" exclusive to Shell: contains ICA This Shell: Shell Motompprata5ss Poorpaan; Ene major Z This master additive blended with Shell gasoline of Additive} incor Puts an 'end -circuicing 0i spark . discovered ~acugnicdort; ano ahoberdi supreme quality, enables cars to keep producing power lois Br combustion chamb 67 deposits ip tetrz ethyl Iead maximum power economically and with smooth of the Rreee tieder" {uel For 3 engine rhythm: L.CA: was the greatest gasoline since the discoveny advance been {0 full use both are Mointis great = eatest F: fouling; idb Here development in 32 years:- That is more apparent today The {7o and spzr Spirit with enginef Are Pre TSAE ~Rotor than ever, and will be even more So in the future: { bY ~hich Ene che reason Mht tne cylinder hot and ienite Depoion become red This Pre" pre- HHIGNitiO : 0( combustion _ the Snendentins noise: be the E m befor runnin and Ping (not rorun Rhe resules.
