240Joe, On the subje of diesel rated oil. When my tech. recommended Castrol 20W-50, I went to Castrol's web site to look up if it was diesel rated. Well fro this particular weight, it has no "CH" or "CG" rating but some of their lighter weight oils do. Should I switch and run the chance of having a higher oil usage? Normally such a thick oil would cause cold morning starts, a problem. Since I am using the block heater, she starts rightup even when it's 22 degs. outside.
