Mobil does make diesel engine oils with 15W-40 viscosity but they are blends -- partially synthetic and partially conventional oil. The higher viscosity 15W-40 oil would normally work better when the engine is subject to high loads and heat conditions, such as towing maximum loads or climbing a lot of hills, but synthetic oils retain their viscosity better at high heat conditions, so the 5W-40 oil should protect as well for normal driving. Another advantage of the wider viscosity range is better lubrication during cold starts, so engine wear is minimized. GM recommends Mobil 1 synthetic oil for several of their high performance passenger cars so the dealers probably can obtain the Mobil diesel oil through the same supplier. I think they made a good choice for your vehicle.

So how long does it take to warm up the engine? On a zero-degree day, oil will be flowing and you can start driving slowly in 30 seconds to a minute. If you have to get out on the highway or freeway immediately, let it warm up a couple more minutes. At temperatures of -20 or below, you are best to let the engine warm up two to three minutes before driving, but then drive slowly for a few kilometres to let the transmission and other rotating parts to warm up, too. Usually when temperatures drop below zero, the ability of the heater to clear the windshield of frost determines the warm-up time. Once it is clear, you are set to go.
Thermostats are important to getting the engine up to operating temperature quickly. The thermostat stops coolant from circulating through the radiator while the...
