I didn't want to dump that oil with only a bit over 1k miles on it, but the car was really not happy when it started on the 15F mornings.
LOL MMO laughs at freezer temps and 0*F, but still a good test to see for yourself. The 22 ounces in your moms car should help. I told this story a few times. I had gone to visit a cousin in the winter who lives in the Adirondacks, upstate NY. I was running Mobil 1 5w30, and I hadn't started my van in about 3 days. It was -30*F or so the day I came home. The noises my van made on startup were sickening.
The following year I went to visit him, it was almost identical weather, and the van once again sat for the same time frame. We were parked side by side. He was running Mobil 1 5W30 as was I, only I had a qt of MMO mixed in this time. Start up difference was night and day, now it was his car making the noises. He became a MMO user, and I add a qt to the oil every winter w/o fail in my van.
Let us know how it works out.
My mom said her car was a lot smoother when she started it this morning (it was about 20F).
That Mobil 1 10W-30 High Mileage does not like colder weather. I had some in my car, and when it started getting cold my fuel mileage dropped like a stone. Simply switching to a thinner oil made a dramatic improvement.
Once the winter sets in you'll see even more of a difference. I've told my story a few times about the Adirondack mountains, I'm sure where you live it's even colder. If you have any oil changes pending before winter try 1QT of MMO for the full OCI. You'll love the stuff and be posting more about! Glad to hear its working for you!
