The reason I am running 5W20 is because most every oil changing facility thinks is that because it has a blue oval on it, there is some kind of federal law that they MUST run 5W20 in it (and, yes I know Ford back specked the engine for 5W20.) I also forgot to request 5W30 this time.
I have asked the 5W30 instead of 5W20 q? a few times,not only here but friends and other mechanics.Here are some of the replies I got;
"You will blow the engine up,You will spin a bearing,Your crankshaft will lock up,and last but not least,"The 5W20 police will arrest you!"
I have a place that I go to on occasion to have my oil changed. It is a muffler place and still will change w/ 5 qts. of Citgo conventional and filter for $12.88. I was in there last year and told the guy that I wanted an oil change and use 5W30. He told me that I would void the warranty. After I got done busting a gut laughing, I told him that 1) the car was originally spec'd for 5W30 and 2) I was curious to know what kind of warranty there was on an 11 year old Ford with over 200K on it? He didn't have a comeback for that; however, I'm sure that the $5.00 upcharge for 5W20 was the impetus for his great concern.
The only thing that 5W20 does for me in that car is absolutely GUARANTEE that I will be topping off w/ a full quart during an OCI. This car uses virtually no oil (< 1/2 quart at most) on 5W30, even with the miles that are on it.
