| .2. The Makers recommend that on this model, an S.A.E. 50 should be used if any continuous high speed running is to be undertaken. Although the official tyres pressures specify for the front wheels - 35 lbs, and for the rear wheels - 30 lbs, I find that I get better directional stability with the front tyre pressures reduced to 28 lbs, though this makes the steering slightly heavier for parking. In conclusion, I know of no better car for the owner-driver of modest means, who wishes to cover long distances with the maximum amount of reliability and the minimum amount of fatigue. Yours faithfully, P.S. My car has still to be re-bored. | ||
