Hi All
I have a 1987 Chevy Caprice station wagon with the 307 Oldsmobile V8 (one of the best engines ever). I mainly use this car as a truck, pulling a boat and hauling around stuff that won't fit in the Focus. Right now I have it filled with 10w-30 Mobil 1.
The car has 227,000 miles on it, still runs great.
Now here is the question: on an engine with this many miles on it, in Minnesota where it is currently 12 degrees in early December and likely to get much much colder, what is the best viscosity to use and should I change viscosities between seasons?
What do you guys think?
