I changed oil in our 2007 Dodge Grand Caravan (3.3) in early September, adding Walmart SuperTech (Supertech) 5W-30. That was at about 276,000 km (171,000 miles).
I consider our driving since about mid-November to have fallen into the severe service category - cold ambient temperatures, cold starts, short trips, and lots of idling.
Several months ago Walmart dropped its price on plain-Jane Mobil synthetic, to where it was price-competitive with the Supertech. That led to me asking here (on BITOG) about the merits of the various Mobil synthetic oils, and ultimately I decided to go with Mobil 1 ESP.
The ESP came on sale at Canadian Tire (CT), so I bought several jugs. (@Patman, I think it was you who gave me the heads-up - thank you.)
Anyway, by yesterday we had racked up about 6,000 km on the Supertech (odometer just under 282,000 km), much of the mileage under severe conditions, and I decided I would change it rather than wait for Spring.
I did the oil change in my garage, which was sitting at about -11°C. The Supertech would not have been much warmer; I started the van briefly, only for long enough to drive it up onto the ramps, and then didn't get back to it for about an hour.
The Mobil 1 ESP, meanwhile, had been cold-soaking in the garage for several weeks (probably more like two or three months).
The Supertech (5W-30) drained out like tar. It probably took half an hour.
The Mobil 1 ESP went in like it was at room temperature - it seemed to be impervious to the cold.
Driving last night, my butt dyno said the van felt much more responsive. I know, totally subjective.
Anyway, there are two factors at play here - 0W-30 vs. 5W-30, and Supertech vs. Mobil 1 ESP.
Regardless, I'm very happy with the Mobil 1 ESP 0W-30!
