[SIZE=+2]TUNING FOR EFFICIENCY[/SIZE]
with REDEX additive
Getting the most out of our available horsepower without extensivemechanical modifications, is an ambition that can now be realised.
Engine efficiency is reflected either in more miles per gallon, or inimproved acceleration—one cannot normally have it both ways atonce!
Willing horsepower is usually the hardest worked and REDEXengineers are concerned to ease the burden on over-strained 'horses'.REDEX is an Oil and Fuel Additive which performs a number of vitalfunctions in a highly stressed engine.
In petrol, REDEX is an uppercylinder lubricant providing lubrication to dry cylinder walls on everycold start.
It will prevent hard carbon deposits forming on valves andpiston rings—a major cause of poor compression—and give muchlonger periods between de-cokes.
A s an extreme pressure lubricant in engine and gearbox REDEXincreases oil film strength, cuts down frictional heat.
As a syntheticliquid wax, it ensures lubrication at high temperatures, preventingpossible seizure during periods of high stress and tight bearing con-ditions. REDEX blends completely with all fuels and all grades oflubricating oil. REDEX is added to petrol, one penny shot (approx.1/2oz.) to each gallon of fuel, and engine oil in the proportion of onepart REDEX to three parts oil.
In gearbox one part REDEX shouldbe used with five parts oil.
The table below shows how acceleration and fuel consumption figurescan be improved after the cars have been 'REDEXED', and subse-quently after ignition and carburation have been adjusted to takeadvantage of the power released by REDEX.

Before REDEX treatment the engine is checked. After taking per-formance times and making an accurate petrol consumption test thesump is drained and filled with REDEX. Plugs are removed and2 or 3 ozs. of REDEX poured through each plug hole and left to soakfor 20 minutes. Plug holes are covered with rag and the starter motoris operated to eject surplus REDEX and plugs replaced. The engine isstarted and set to run at a fast tickover for 15 minutes, during whichtime i pint of REDEX is bled into the inlet manifold. The sump isthen drained and refilled with one part REDEX to three parts oil.Sparking plugs and contact breaker points are then cleaned and ad-justed, and the timing accurately reset. It is possible to obtain a quickand more accurate ignition setting by using a REDEX tuning gaugethan by reference to flywheel markings. Carburettor adjustmentsshould be made and the car can be rechecked for performance andconsumption.
