i just got an email from Mobil 1 announcing their new Mobil 1 EP High Mileage. When I looked at the "product specs" sheet for the 0w-20, I see the phosphorus is 800 and the zinc is 900. In the past, I used the Mobil 1 AFE 0w-20, which has phosphorus 650 and zinc 750. Some years back,when they came out with the Mobil 1 EP in 0w-20, I saw it had phosphorus 800 zinc 900,so I switched to it. Now, when I look at the "product specs" for all the Mobil 1 0w-20 oils, I see the only one with phosphorus 800 zinc 900 is the new EP High Mileage 0w-20. The 0w-20 Mobil 1 EP is no longer phosphorus 800 zinc 900, it is now phosphorus 650 zinc 750.
My question is does this really make a difference, and should I switch to the new Mobil 1 EP High Mileage 0w-20?
