Valvoline VR-1 vs. Lucas Hot Rod oil

d so did windman recently revise?well I see he did so I re-read it
looking at the first graph in post 90 it is clear that a 5W would be below the blue 10W
line and a 0W would be below that
better start up and cold flow where most of your wear is
comes out the same at running temp
so pick 0W 15, 20,30,40 whatever operating viscosity you need
Whats different
not too long ago multi grade oils required viscosite improvers which "shear down"
the new Type IV & V basestocks do not
how to pick
learn to read the msds or just pick a 15000-20000 mile oil
old basestock oiles including type III cant get there
now with a carb you do ot want to push the milee for other reasons
