WHat should it be? Because last time the dealer put 5k on the sticker but this time they put 3k?
I push my car pretty hard every day!!! Not very many miles, but i work it in those miles. So I go 3 mo or 3 k miles.Butch said:I go 3, regardless oil suggestions
I go 5K if not a little over. I think they are busy and forget. They wrote 3 on my moms to. The only real way to know is to have an analysis doneNicholasP said:WHat should it be? Because last time the dealer put 5k on the sticker but this time they put 3k?
+ 1 on that Jim! Ford spent a lot of $ on R&D to determine the exact grade, fill level, and duration. Now I'm sure that 5K number is a fleet average among gasoline vehicles.JimC said:The oil change places are in the business of ...............................selling you oil.
So of course they want you to change it frequently, no matter what the manufacturer recommendation is.
The manufacturer is in the business of building cars and warranties those builds. So they take the time to figure out what the oil change interval should be. If they are wrong - then they get to put a new engine in the car.
Which recommendation is probably the correct one?
When I had my 2006 I had the oil tested every third oil change. They had me increase the interval to 8,000 miles. I drove the car hard - over 3,000 miles a month with weekend drag racing on a supercharged V6. I sold the car with 203,000 miles on it and the last test said no problems or abnormal wear. The new owner said it is running great still.
On the 2013 Ford added an oil monitor and I'm following that. My wife doesn't drive her MKZ hard at all and she gets a lot more life on her oil. I still drive the car hard so have to change more frequently than she does - even then it is more than 5,000 miles, and a lot more than 3,000. If you change it more frequently it may give you "peace of mind" but you are wasting your money. Get the oil tested (I used blackstone labs) and see what they say about your car.
The owners Manuel says every 10k for the 3.7 we got????nhcowboy said:I push my car pretty hard every day!!! Not very many miles, but i work it in those miles. So I go 3 mo or 3 k miles.
If you drive conservative, 5-6 is probably fine. That I think is the factory interval (if not more).
