Question:
Mixing Motor Oil Viscosities to Achieve 0W-40
0W-40 is not available in my area. What other weights can I blend to achieve 0W-40? Example: 1 quart of 0W-30 mixed with 1 quart 10W-40 equals 0W-40?
-- Gracie Dog, Columbus, GA
Answer:
Viscosity grades cannot be obtained as described. Please follow the manufacturer’s recommendation and please use the oil as it was manufactured. Our online Product Locator shows there are at least 10 stores in the Columbus, Georgia, area that carry Mobil 1™ 0W-40.
