motor oil & other fluids

["Linda Grunthaner" <grunthaner@gmail.com>]

I was reading my Haynes book and it said to use 20W50 motor oil in the 1275
engine it seems too heavy is it correct. If not what have any of you used &
liked? Also what spark plug is good for the 1275? And what gap? Last what
break fluid?  I used Gerling for my 68 Spitfire is that what I should use
and are the break & clutch master cylinder combined on a 62 Sprite?

Thanks Linda
