Re ENGINE OILS FOR CONTINENTAL USE. Referring to BY/SB.{Mr Bull/Mr Bannister}2/MG.7.3.39 and Depot Sheet No. BY.6; we would suggest that we issue a leaflet reading as follows :- Use of Light Engine Oils. When the car is likely to be driven hard, as on Continental roads, the use of a viscosity 20 engine oil should be avoided. This would face the page giving "Recommended Lubricants" on which appears a statement that a viscosity 20 oil may be used if it is found difficult to start the engine in cold weather. Will you please let us know if you approve. N.W. Handwritten note: SB{Mr Bull/Mr Bannister} You answer this Gys | ||
