Just a slightly thicker cold viscosity oil. Some people who live in hot climates will use an oil like that, or in an older/higher mileage engine to try and control leakage a bit.

Re: Mobil1 0w30? (IcemanZ06)
0w30 is used for extremely cold temperatures. Once the oil is warmed up to normal operating temp, it should have the same viscosity as the 5w30 or 10w30. The first number represents the viscosity at a certain cold temperature, and the second number represents viscosity at a certain hot temperature. At the cold temperature, a 0w30 has the viscosity of a 0 weight oil. A 5w30 has the viscosity of a 5 weight oil, and so on. At the hot temperature, they all have the viscosity of a 30 weight oil. The lower cold temp viscosity (i.e. 0w30) is generally better for reducing wear upon startup.

Ford is also using it in some of thier new cars.....i.e. the Focus.....the Ford guy told me it helps gas mileage.....every lit bit helps I guess......

Have you seen the new 5-20 that ford is using? So far they are the only suppliers of it as well. (that meets their specs) I guess it is one of Fords better ideas :rolleyes:

Re: Mobil1 0w30? (merrick)
I read one time in super chevy I think that on a dyno a 350 made the most hp with a 20-50w oil. I've ran 15w-50 in my vette since I got it, I just recently went to the 5-30 again to go with the lower weight, more power theory. I don't know though. I think I may go back to the 15-50 mobil1?!?!
0 weight just sounds bad to me.

Re: Mobil1 0w30? (85 Dave)
Actually, several oil companies now have the 5w20 oil that meets or exceeds Fords requirements. The lighter oil improves fuel economy. What's wrong with that? BTW, the Ford oil is manufactured by Conoco, and its a hydro-cracked oil. That's the same process that Castrol uses to make their "synthetic" oil. But the Ford oil is about half the cost, and they claim it to be "semi-synthetic". From what I've heard, its the best bang for the buck right now. But I doubt our Vettes will be able to use an oil this light.

When I lived in snow country, I used the 0-30wt Mobile One. I felt it made it a little easier on the engine on start ups in the cold months. I did however switch back to 5-30wt as the weather warmed up.

Not according to the Pat Goss show. There are other manufactures of 5-20 such as pennzoil but they are not reconized by ford at meeting their specs. As far as what is wrong with it, I do question the use of a 20 weight oil in a vehicle in a hot climate. Is it being done just to meet fuel milage requirements?
