Valvoline VR-1 vs. Lucas Hot Rod oil
take a quart of your 30 weight oil at 200 degrees, use a double boiler on the stove, now po it through a smalll funnel- how long did that take?
now take a quart of your 0w 30 and throw it in the freezer then pour it through your funnel
they will be about the same
thin oil is 20 vs 50
0W has nothing to do with
