Message Could the extra 5 in cold viscosity be the culprit? With all the extra headaches we ran into I completely forgot that I had them change my oil while I was there. They use Swepco 15/40 where I usually run a 10/30.

And if this is the answer, given that I have cold starting issues, should I run a lower cold visc oil during the winter months going forward?
