Question : what Oil would you run synthetic or continue with Standard Oil
I just bought a used 2017 to my collection with the 3.5 EB. It was one owner with 75K miles
I am wondering if it is in best interest on the EB to change over to synthetic or stay with std oil with 75K miles in mind?
I am going to add a tuner, air intake, throttle body etc like my 2015 has so that said what would everyone do?

Thanks

 

I use semi-syn 10-30 I believe, on my 13. 3.5 eb. Change every 10k. I have 165000 easy miles. Use is travel only. Ford dealer changes it. No complaints.

 

Another oil thread


10k on an oil change for a EB has been proven to be way too long. Glad it is working for you.

 

Thanks, but what has been proven 10k is too long? I do 80% hiway miles w max 70-72 mph at cruise. No tow or hauling. I’m very open to suggestions, especially w my high miles. What if I use full syn at a 10k change?

 

I have an ‘18 EB and I use full synthetic every 5000.

 

Good idea, I might do that based on my mileage. Likely worth it. Thanks.

 

..

 

Been running full synthetic in my 2019 3.5L its entire life, oil changes every 4000 miles with stock filters, 152,000 and going strong.

 

Ford now specifies Full Synthetic motor oil for new F150, any turbo motor should be running Full Synthetic.

 

True, I run Royal Purple with a cheap oil flush/clean before the fresh batch of the good stuff goes in (@ 5k miles)
