My 94 Honda Accord started with no hesitation this morning at a temperature of 5 F. My car always hesitated slightly at these temepratures when I started with Mobil 1 0W-30. There is also very little valvetrain noise at startup in the cold. Hondas are known for their loud valves during cold starts. It looks like the green stuff is living up to its hype in the cold. Maybe that -81 F pour point is legit. The forecasted low for Friday morning is 8 below zero F so we'll how the green does.
