FURTHER evidence of the economies that can be effected by the use of the preparation called Redex, produced by the. Wayne V. Myers Co., Ltd., 57, DeThen Street, London, S.E.1, has reached us. It is so convincing that we pass it on for the benefit of others.
Redex is intended for introduction into both lubricating oil and fuel. It has been on the market for about eight years and is described as containing an extreme-pressure oil ingredient and a carbon repellent. With regard to the former, the effect is that when it is added to sumps, gearboxes, back axles, etc., the oil-film strength is raised and the lubricant is better equipped to meet the needs of the high hearing and tooth pressures that are common to-day. By the use of Redex, it appears, performance and consumption rates improve, and if jet sizes be cut down suitably a further decreased consumption results without affecting the standard performance. Figures relating to savings, brought about in this way (but not necessarily by altering jets oat injection-pump settings) by a number of prominent operators, have been supplied to us by the maker and we quote below from this information.
For the Leicester City Transport fleet, we understand, 500 gallons have been ordered for 115 vehicles, tests having revealed an improvement of 2 m.p.g. after adding the preparation to the oil in the engines, gearboxes and back axles of certain Leyland doubledeck oil-engined buses. On a Leyland Hippo, operated by P.X.. Ltd., one of whose vehicles is featured in an accompanying, picture, the consumption rate improved from 7.3 to 8.3 m.p.g., by similar treatment, whilst on a Morris-Commercial 3-tonner on delivery work six more miles per gallon were obtained. The company ordered 280 gallons.
S.P.D., Ltd., operator of 2,000 delivery vehicles, which are under the control of that well-known personality Captain Walton, carried out a test of Redex with a Commer 3-tonner on Croxted Hill (Crystal Palace), using a Tapley meter and inserting Redex only in the sump oil. A reduction of 20 seconds was recorded in the time taken to climb the hill, the figures, respectively, with and without Redex being 3 mins. 32.7 secs. and 3 mins. 53.8 sees. in this case the consumption rate was bettered by 18 per cent. (11 m.p.g. to 13 m.p.g.). Subsequently, by adding the compound to the gearbox and axle a further quarter of a mile was added to the distance traversed on a gallon. This concern, we are informed, has purchased 150 gallons.
From Edwin Jones and Co., Ltd., comes news of compression ratio improvements of about 9 per cent., higher speeds, and quieter transmission, from George Monro, Ltd., of satisfactory running—by means of Redexof a 20-year-old 5-tonner that was brought back into service after having been out of commission for 2 years, and from the Metropolitan Transport Supply Co., Ltd., of 20 m.p.g. as cornpared with a former 14 m.p.g. from a 6-ton oiler, to, the sump oil of which one gallon of Redex had been added and to the gearbox and back axle one quart, respectively.
