THE NEW CASTROL
In technical circles some very cutting things have been said of late about the heavy oils, even winter grade, that we use in this country. This has been particularly noticeable at recent I.A.E. meetings, where the feeling has been that America has been ahead of us in this direction. Anyone listening to these discussions must have gone away with the disturbing thought that here was no highbrow technical matter, but one which was of vital importance to the ordinary motorist seeking easy starting, long cylinder life, and efficient running. It has been left to the initiative of the great
Wakefield oil house to remedy the previously existing state of affairs. They have perfected, as one would expect Wakefield’s to perfect before marketing, new, lighter grades of Castrol oil.
These new lubricants contain stabilising agents which fortify them against filmbreakdown, they retain the desired viscosity when hot, and they retain the compounds of chromium and tin which reduce cylinder wear by corrosion and so make lighter lubricants very necessary. But they are lighter than previous grades, just as the technicians have ordered. The new grades are easy to remember (a) Patent Castrolite in lieu Of C.W. ; (b) Patent Castrol XL in lieu of AA or XL ; (c) Patent Castro’ XXL in lieu of XXL. More than ever before is it essential to emphasise the Castro! brand. The introduction of these new, lighter lubricants marks a very big advance in lubrication technique, and, quite seriously, we shall drain the sump and refill tonight. Research dictates that sports-type engines, in particular, shall run on light
lubricants. Messrs. C. C. Wakefield & Co., Ltd., Wakefield House, Cheapside, London, E.C.2, will gladly put you on the correct path if you contemplate taking advantage of this new epoch and will send them details of your car.
