My dealer told me that this car uses a synthetic 0w40 . I have never heard of 0 weight oil ? to me it means nothing, nada, zip. What is it? lighter that 3 in 1?
Thanks

My wifes SmartCar uses it too. Don't know what is special about it.

very light weight oil, helps it get the advertised 40+ mpg.
Both the Hemis I've owned take 5w20, which isn't much heavier.
