Recently I puchased a 1963 pontiac starchief with 38000 orig. Mi. : D So I take it for a spin and everthing is grand. Afterward I checked the oil and it was a little low(heard warnings about oil burn-off in older motors and wanted to be pro-active) so I added about a quart of 10w 40(after input about its protective properties). Problem is it takes 20w or 10w 30 as a poss. Alternative. During driving everything is fine, but at stop and idle there is a little more vibration. Incidentally, it is about 35 degrees outside. Any ideas?
