Considering a 2008 F150, what to watch out for?

General Discussion

This would be my first Ford truck so looking for any insight into common issues I can be on the lookout for in regard to this used truck.

2008 F150 XLT SuperCrew 5.5 ft bed 4x4
5.0L V8 OHV 32V Flex Fuel
10 speed Automatic 4WD w/Tow and Plow pkg
116k miles
1 owner

It’s at a small dealer near me. They painted the undercarriage which I hate when they do that. It has rust as expected but doesn’t seem to be out of the ordinary for around here. Is there any specific area I should inspect that is common rust concern on these?

I am not big on the Flex Fuel or Auto Start/Stop “features”.
Is this V8 an AFM design?

Any issues with the 5.0L in this year F150 I should be aware of or things to check?

Appreciate any perspectives here and advice on inspecting it…

Thanks!

2018 5.0L DOHC 32V
or
2008 4.6L SOHC or 5.4L SOHC??

You can delete the start/stop..

And the flex fuel really doesn’t affect anything if running regular E10>… My 1999 Grand Caravan was flex fuel, would never know it if you never read the gas door or looked up the VIN engine code…

I think 2018 was the 1st year to run the 10 speed, so cutting teeth issues…

I think they had high oil consumption issues, I think it was 2018 and 2019 were the worst years for using oil…

Agree with @davesmopar on all this. The 5.0 is not an AFM engine. Like any modern engine, it does not like deferred oil changes.

And this engine holds a LOT of oil. 9.5 quarts, I think. If this is like the Mustangs it has a low oil switch in the pan. Like me, you will likely never see it.

The flex fuel sensor is a passive device and measures fuel permittivity, and maybe fuel temperature. That seems like a small issue. I imagine that you won’t race the truck or add a turbo (well, YOU might :wink:), so running E10 isn’t an issue since that’s the default.

Yes, 2018.
How the heck did I screw that up??? No need to answer :grin:

That’s great! Thanks.

They have the CarFAX and it appears the first few oil changes were on a 10k schedule and then no further entries. I assume the owner decided to do them and if there’s 9.5 Quarts, I might understand why.

:smile: Nope, this is just for winter commuting and home driveway plowing.
