I have been using Mobil 1 Ow-20 in the 4 cyl Terrain and coming up on the second oil change soon. Is this oil OK as the owners manual say 5W-20 but on the back of the bottle is says it is a good replacement for it with better fuel economy. I just don't want to hurt the motor and I can take the 5 quart bottle back and get the 5W-20 before its next change. HELP
Do you mean 0W-30?
If its 0W-20...Sorry you have issues! The engine is not designed for 20weight
If its 0W-30...30 weight is the oil GM specifies, and typically 0W is made from better base stocks (opinion). If you live in the cold climates. I know alot of people that run 0W year around because of the feeling and oil anaylsis coming back of better base stock. I usually run 5W because slightly cheaper and I live in FL
The first number is just the "cold flow sae rate"...At operating temp both the 0W, 5W, 10W have the same "thickness"...its just different @ cold temperatures
