Can I use 0W20 synthetic oil in my 2017 F450 with the 6.8 V10 engine?

 

What does Ford recommend?

 

Ask in the 6.8 V10 forum. I had a V10, 2 of them. Stick with 5/20. I live way down south, so I used 5/30. No benefit to using 0w unless you live in a very cold area. It won't hurt though.

 

Posted in the wrong forum, but I don't have mod rights here to move it for you.

I ran 0w20 in my '00 V10 and never had an issue. You won't hurt anything with it, but you may not see much of a benefit unless you operate in colder weather.

 

Back when I changed my oil I always used 0W20 and never had an issue. My dad has been using 0W20 in his 2001 F150 since he's had it & I used 0W20 in it before I gave it to him. The truck will be 17 years old in October and has 140,000 miles on it today. It runs perfect and uses no oil.

 

Found this article today. Not surprising, but does help confirm what we think.

GOOD POINT!

While still in drive train or extended warranty, use only what the Owners Manual calls for.

When out of warranty, it is yours and then start experimenting.

 

You can run 90w gear oil if you choose. Me, I'll stick to the factory recommended oil. They pay those engineers the big salaries for a reason.

 

Stick with what Ford recommends for your vehicle and go with the Motorcraft Full Synthetic instead of the synthetic blend.

 

I take mine to the Quick Lane at a local dealer and just tell them to give me the works. They use the synthetic blend. No need to run full synth if you are changing it every 5K miles.
