Just changed the oil (new to me used 2011) and went to reset oil life and it won't change from 26%, reset on another menu to 100% but the oil life won't go to 100% what gives?? Another question... going to change coolant tomorrow, didn't really look around while I was under the truck. I assume theres a drain valve on the radiator to drain it and afterwards fill with about 6 gallons through the expansion tank? I'm in the process of changing all of the fluids so I know where I'm at being that its a used truck with high milage

 

How many miles do you have on the truck?

 

Interested to know this too. I haven't had my first oil change yet but would like to be prepared

 

Maybe you don't have an owners manual with all the explanations of the truck, you can also goggle to find a owners manual and download it. Here you go. http://justgivemethedamnmanual.com/f...owners-manuals

You probably already know this.. but change your oil before 1500 miles for that new engine..

 

Did my first oil change last weekend. (Mobil1) Afterwards, I went into the dashboard menu to reset the oil life, and it had automatically reset itself to 100%. I was a bit perplexed as I didn't think the truck was smart enough to know that the oil & filter had been changed.


Also installed a Fumoto valve to make future oil changes easier

 

Yep. Thanks. I actually did it last night after getting close to the 1500 number. Changed with with Motorcraft this time, since I will be changing it at 5k, and at that point going forward I plan on running Red Line Full Synthetic. I've run it in the Mustang since I got it with 16k miles and at 70k it has perfect compression across the board.

 

did my first oil change last week, and the oil life did not reset itself? I'm changing on the 5's anyway so I'm not real worried about it, but the oil life indicator seems pretty useless as it will let you go ~8k miles unless you tell it otherwise...maybe 8k is fine? I do think 3k is a waste of money/oil....... but if you don't mind that...it certainly won't hurt.

 

I was at 45% at 4000 miles. Changed the oil. Started it up. 100%.

No idea.

 

i had to work my way through resetting mine the last two times i had it changed at a FORD dealerships the first one was at Kool Ford on the eastern shore of Virginia and the last time at Ken Stoepel Ford at Kerville Tx.
