Oils listed in book are: Standard Oil Co. RPM,, Esso 2-Stroke Engine Oil,, Caltex 2-stroke Engine Oil,, Valvolin Oil Ref. Co. Valve mix,, Mobil Oil Co. Mobil mix. 20W or 30W depending on temp and do not use detergent oil. I last drove this car in mid 80's and am not sure what kind of oil I used. Not sure if I ever added oil as it was not driven much before parking. Any suggestions?
Thanks
