A GOOD QUALITY SPORTS OIL.
WE have just completed an extensive test of the new ” Sports ” Filtrate oil, recently introduced by Ed. Joy & Sons, Ltd., of Leeds. The claims for this oil are that it retains its viscosity to a remarkable degree, even when really hot, avoids gumming up in cold weather, and prevents a heavy deposit of carbon. The car used for our test was a Talbot” 90 “sports model, the sump of which was carefully drained and filled with ” Sports Filtrate.” Starting from cold, the engine proved completely free after the first few revolutions, and yet as the temperature grew higher no large drop in the pressure took place. Indeed on one day of the recent hot spell the car was driven hard for many hundred miles, at the end of which the
oil gauge showed a powerful pressure even when ticking over.
Consuniption was low, and at the end of 500 miles we found the plugs,. which had been carefully cleaned at the beginning of our test, covered only with a thin film of easily removable carbon.
Altogether, we found “Sports Filtrate ” to justify fully the claims. of its makers.
