Well today I changed my oil, I Put Mobil 1 Full sysnthetic 10w-30. Now the owners manual recomonds 5w-30 but it says you can use 10w-30 if the weather does not go below 20 degrees. Well I live in New Jersey and once in a while it does go below 20 degress Should I be concerned? What can happen?

 

you can run 10w30. I do in summer. But as far as winter goes, just let the car warm up close to running temp before driving. Reason being, the 10 weight oil is slightly thicker and will need to be warmer to operate and the right viscocity.

Don't worry, you'll be okay.

 

Ok, Thanks, Just didn't want the oil not running though the engine.That would be well....bad...lol
