Hi guys new to the ford scene. I just purchased a 2017 f150 king ranch with the 3.5 ecoboost. My understanding is that the factory oil is a synthetic blend. My question is when should I don my first oil change and also how soon can I change to full synthetic? Thanks

SCrewYou

i did mine at 3,000 miles.

Bumrush

Did you also go full synthetic?

SCrewYou

nope. dealer changes my oil with the motorcraft blend.

Oil change intervals are VERY opinionated. You're gonna get lots of answers.

- At 1K then every 5K
- Every 5K
- Every 7K
- Every 10K
- When the truck reminds me

I went full synthetic since first change. Pennzoil Platinum.

I too went full synthetic on the first change at 3K. I am about as old school as you can get; even though the truck will tell me I still change the oil every 3K. Old habits are hard to break. The again, I also have a 1999 Toyota Tacoma with right at 268K miles and I would still drive it across country today. I take care of my toys (no pun intended).

All three of our trucks (wife's is also a Toyota; 2008 Tacoma Pre-Runner) and all get changed at 3K and full synthetic.

i should probably clarify, i don't change my oil every 3000, i did the first change at 3000. i do it every 6000-6500 now.
