OIL

[Mr D]

Mobil 1 10-30 in the summer, changed every 2K miles.

Mobil 1 5-30 in the winter, changed every 1500 miles.

My ride is driven in Alaska where even in the summer the engine runs cool, cold engines produce more acids and contaminates to break down oils. Also moisture builds up faster and cold starting oil with even small amounts of moisture can cause oil starvation in critical areas, better to be safe than sorry, I just stockpile the Mobil 1 when its on sale.
