| Re Oil Can you get the S.A.E. rating of the suitable Essolube oil that compares with Mobiloil B.B and Arctic? We always go by this in America, such as S.A.E. 30, 40, or 50. Is there any harm in using a light oil most of the time? It may get used up quicker but I change every 1000 miles anyway. I find that the American cars start and run a bit better on light oil, even in summer. Re Anti-Freeze mixture: Do you happen to know the commercial name for Ethylene Glycol in America? TELEGRAMS, CORTACHY. TELEPHONE 31, CORTACHY. CORTACHY CASTLE. KIRRIEMUIR. ANGUS. be done, due to a different clutch casing I believe. If it is possible to install the shock control, I would appreciate it very much. Re Petrol What petrol do you consider will give me the best results? A Benzol mixture or Aviation? I hate ethyl, as it messes & dirties up the motor so. I can obtain pure Dey. Benzol at home quite easily, but I don't think it is the same quality as you have here in England. | ||
