>From what I read on the Mobil 1 website, they don't recommend the 5W40 oil
in vehicles with catalytic converters, due to the zinc and phosphorus
levels. I am going to use the 5W40 in my '50 8N Ford tractor. I used to
use 15W50, but I can't find it in my area anymore. I've used 10W30 for the
last 2 years, but the 5W40 looks like it might be a better fit.
