High zinc oil?
Ive been using mobil 1 5w-20 advanced full synthetic for my oil. I have cams and I heard that with lopy cams you need to have high zinc oil to protect them. Otherwise the lobes will wear down. Is mobil 1 full synthetic enough? Or shuld I buy a high zinc oil?

Do you have cats? High zinc oils will destroy cats ove time. High zinc oils are good for bearings and the only reason companies changed are the emission requirements. You don't have to run high zinc but I would change from Mobile 1, it has been shown to be one of the worst oils. I prefer Amsoil myself http://www.amsoil.com/storefront/rd20.aspx but Valvoline is also very good http://www.valvoline.com/products/co...ic-motor-oil/8 in 10w30. If you really want to learn about oil the go here. http://www.bobistheoilguy.com/

The only reason Ford went to 5W20 is for posted mileage, thin oil gets a little better gas mileage. I run 10W30 in mine because it's not stock anyway. If you have a stock engine you can still run 10W30 and have the advantage of a better safety margin. Myself I really wouldn't want to be turning 6500 rpm on 20W oil. Why do you think the GT500 runs 20W50 oil? Higher HP requires better lubrication.
Mobile 1 used to be a great oil but once it got popular they changed it and it doesn't fair very well in testing against the better synthetics.

I was told about this oil in a speed shop. They sold high zinc oil there, but what I am confused about is the link he sent me states that you should go from 5w20 to 0w20 not 5w20 to 20w50. It was saying that oil does not get thin enough to harm the motor and it actually flows better when it gets hot
