“The price btw for Pennzoil 5 quart jug was just $13.00 plus a five cents Alabama oil fee. No sales tax. Again was in the same store and they had the 1 quart, same oil for $2 a quart so got 6 more.”
The next time you go back I would not expect to find that anymore. Personally I would stick to the manufacturers recommendations on oil weight.
The owner’s manual calls for 5W-30 for normal driving.
After 200,000 miles I figure it doesn’t much matter. It never has used oil tho. I was a little surprised that it didn’t go through the rings, especially since it poured like water.
