New guy here. I bought an 2011 F150 a few months back with 45,000ish miles on it. Around 48,000ish miles the truck told me I needed an oil change. I put Quaker state 10w30 full synthetic in. At 53,000ish the truck said I need another oil change. I am approaching 58,000 and according to the vehicle report I only have 27% oil life left. Everything I have read online says that the computers are set to get 10,000 miles on an oil change. Can someone offer some suggestions? thanks for the help

 

Which engine in your truck?

 

I have the 5.0 v8

 

I'll let someone with 5.0 knowledge answer- but in the EB, it's best to keep the changes around 5000 miles with full syn, due to the direct injection fuel system. But as a suggestion, you might look into pulling a sample for Blackstone and see what they have to say. I'm one to go with a 5k OCI unless there is good reason (Blackstone report or similar) to extend. I used to run 7500 OCIs on my 7.3L diesel, but that was because I was running full syn and Blackstone showed good oil still at those mileages. I could've gone to 10, but never felt comfortable going out that far.

 

The interval is determined/computed by an algorithm that includes such things as ...

• drives - long haul | short trip.
• towing.
• severe service | normal.
• extended idling.
• driving style.
• oil used.
  etc., etc., etc..

As such it's probably not uncommon to have the oil change interval computed to be prior to 10,000 miles.

Use 5W oil not 10W.

5.0 truck. I schedule my change once I roll 5000 miles. I've never had the oil life monitor warning come up. These trucks need almost 8 quarts of syn-blend 5w-20. I use motor craft. You should too since it sounds like you're still within powertrain warranty.

 

If you have the center info display (where your gauges are), did you reset your oil to 100%

 

Most of my driving is short trip stuff. Yes I did reset the oil life after I change the oil. I will try switching to the motorcraft 5w and see if it make a difference.

 

the type of oil you use will have no bearing on how the algorithm calculates your Oil Change Interval (OCI).


the 2011's use a fairly complex algorithm to calculate your oil life based on the actual conditions the vehicle sees in use.


if it is telling you to change your oil at 5,000 miles it is because you need an oil change.


full synthetics or boutique oils (amsoil, redline, ect) can add a degree of buffer so that the oil isn't actually "used up" when the Intelligent Oil Life Meter (IOLM) says it is ..... but that puts you back to square one as far as knowing what your OCI should be.


if it were my truck, I'd use what ever oil you feel most comfortable with (brand) of the correct grade (5w20) and change it when the IOLM says it needs changed. to prove that the IOLM isn't wasting your money, you could do an oil analysis to verify, but from what I've seen the IOLM correlates very well with actual life left in the oil.


short trips are harder on oil than long trips, so the OCI on a vehicle that sees substantial short trips will be much shorter than one that sees a lot of highway miles.

 

changed oil in all my vehicles @ 5000km or 3 months. Never let it get black & filthy looking. ..oil is cheap compared to a motor.

 

2013 with a 5.0 and I've been using Blackstone to analyze my oil. Using full synthetic (I'll leave the brand name out) and not commuting to work, just mostly highway and some day trips into town (20 miles each way) the oil can stay in over 10K miles.

Drop it out early or use and analysis if you're interested in going farther. You don't need to analyze it each time, just enough to figure out how far it can go.
