Rawtenstall's Experience with the First Leyland Oil-engined . Buses

MWO Leyland oil-engined double...I_ deckers have been in operation at RAWTENSTALL since August last, and the vehicles have now run between them well over 60,000 miles. Although these were the first oil engines to be embodied into passenger chassis by the Leyland concern, Mr. Frank Lythgoe, A.M.Inst,T., general manager of the corporation tramways and motors department, informs us that they have put up an excellent performance and, apart from slight bearing trouble at about 9,000 miles, they have not given the slightest cause for worry.. As a Matter of fact, this trouble was discovered during a periodic examination, with the result that it did not cause any breakdown in the service.
The vehicles are operated on a gruelling route previously served by tramcars, with stops at 200-yd. intervals and several gradients. The oilengined buses are giving a fuel average equivalent to 9.2 m.p.g., whilst the rate of lubricating-oil consumption is, we are told, quite good.
There has been no trouble with oil dilution, and a test made only a few days ago on lubricating oil which had been used for 2,500 mites indicated that there was still no dilution taking place. Exhaust fames are scarcely detectable, and there is hardly any smell.
