Mobil1 0W-20 / Mobil1 5W-20
So, I'm out and about getting some regular car maintenance done and I go to the oil and oil filters area... I pick out what I normally get, right next to the mobil1 5w20 is mobil1 0w20. It boasts better fuel economy and it says that its okay to use in place of the regular full synthetic 5w20. So.... I am confused... What's the technical difference between the 5w20 and the 0w20? Is it really worth it?
Cause I was sittin in there for a pretty long time trying to decide. And they had a sick deal going on too. 5 qt's of mobil1 ful synthetic and a mobil1 oil filter all for $34.99

Re: Mobil1 0W-20 / Mobil1 5W-20
So, to my understanding, the number that is followed by a "W" (5W) is how thin the oil is in a cold temperature setting, and the number after that is how well the oil flows through the viscometer at temperture of 210 degrees(normal operating temperature of a car motor).
I am assuming that using the 0W-20 would only show its colors at engine startup, and not during regular travel, being that it shows the SAE number of 20. The only time the 5W-20 oil is "thin" is at cold start up conditions where you need it to be "thin." As for a 0W-20 motor oil, it is THINNER(than 5W-20) at startup making it more free flowing when your car starts up. but when it moves up to regular operating temperatures, it performs exactly like a 5W-20 motor oil would.
With this in mind, I think that the 0W-20 motor oil from Mobil1 would only prove to be more efficient during cold temperature startup(or winter time?). This allows the oil to reach the engine's critical parts a little quicker than 5W-20. But when the motor gets up to temp, they will both perform equally the same.

If you're concerned with cold-start engine wear, use an oil additive or something, don't use the wrong oil just for that sake.
But hey, it's your car, so do as you please.
