I’ve had (3) 5.0’s a 2013, 2021, and a 2025. Never had any engine oil consumption issues with the first 2 and my 2021 was strictly a work truck and I hauled a lot with that. The 2025 just got to its first oil change and so far so good

 

Would go STX with 3.73 rear gearing and locker with either the 2.7EB or 5.0.

Presently driving a 22 302a XLT Screw 5.5 box 4x4 payload package that has 3.73 gearing and simply loven it.
2.7EB does nose over in MPG with 3.73 gearing in the 70-75MPH area. Had a 16 2.7EB with the 3.55 gearing and 65-70 MPH was the dive point on MPG.

2.7EB loves it's turbos and keeping out of boost is key to good MPG with the 2.7EB or 3.5EB engines

5.0 has now had 4 years of use and the message boards are not overly lite up on cylinder de-activation or oil consumption.

Going 3.73 gearing will help slightly in the de-activation mode in with the 5.0.

3.73 will also add smiles at take off with the 5.0.

If today the 2.7EB payload package got wrecked it would be replaced with a 5.0 and 3.73 gearing or a RAM with the 3.0 Hurricane engine with 3.92 gearing.

Old school rear end gearing here and the new 8 & 10 speed make the 3.73 and 3.92 gearing simply marvelous.

 

3.73 w/ 2.7 keeps a bit lower boost as well

 

Boy did this devolve into a religious discussion.

My last 5.0 went 175k miles with zero oil consumption. Mobil 1 full synthetic every 6k .
The 24 5.0 is at 16k, zero oil consumption, and I have switched to 5k change intervals just because.

The most personal facts we have are based upon our life experiences and what we see with our own eyes. Not understanding much of the acrid tone and personal attacks here . Yet another instance of wishing for the good old days when people could converse without attacking each other. Dayum.

 

Folks lets all take a step back from the keyboards and recall these are discussions.

This is not a life or death matter.

Please keep all chat respectable and in line with rules

Any further problems will result in the thread being closed.

Those in violation have been dealt with.

 

Since we are talking about the STX model here, the 3.5L EcoBoost isn't an available option. The base engine is the 2.7L and the 5.0L is optional.

I've driven the 2.7L trucks (several of my friends have them) and I've owned the 3.5L and 5.0L trucks myself. My take on the 2.7L/3.5L versus 5.0L debate is this: From a pure driving standpoint the 3.5L EcoBoost engine has much more low end torque and the truck is a lot peppier than it is with the 5.0L. This even goes for the 2.7L engines to some degree as well, though they run out of top end a lot quicker than the other two. Up to 60MPH or so the EcoBoost is going to get you there quicker. At higher speeds like 70MPH plus, acceleration is in the 5.0L engine's favor. It has more top end than the EcoBoosts do. From a towing standpoint, the 3.5L is the engine to have plain and simple. Personally, I like the exhaust note of the 5.0L and missed it on the 3.5L trucks. Not that its a huge deal. As for issues and reliability, there are law suits and seemingly more issues with the 3.5L than the other two engines and the 5.0L even has some problems too. It's all luck of the draw really, but there is evidence suggesting the 3.5L is the "least reliable" of the three engine options. The 2.7L on the other hand is almost problem free. It's probably the best engine on that front.

That said, I haven't personally experienced issues with the 3.5L or the 5.0L engines. None of my friends have had issues with their 2.7L engines either. That's my experience with these engines.

 

I feel that the 2.7 will be remembered as one of the best all around engines from these generations. I’ve had two, and even though I like my current RCSB 5.0, I miss the 2.7.

 

It's a good engine, that's for sure. It's just not what I personally prefer.

 

I went with the 5.0 myself. My reasoning was this:
My friend's dad buys and sells rebuilt trucks that have been sold for various reasons (mechanical issues, collisions, etc.).
I know he has had F-150s in with the 2.7 EB that required turbo replacements at only 60,000 miles. No issues with the 5.0 models.
I have a family member that owns a nationwide delivery service that does light freight deliveries. They had longevity issues with all of their EB models vs their V8s. The V8s were getting around 500,00 miles before requiring replacement (although the transmissions needed replacement/rebuilding at around 200k regardless of engine).
I have also watched various Ford mechanics that rated the reliability and frequency of repairs of the engines and the 5.0 always had less problems and came in less frequently than the others. They did say that the 3.5 has improved a lot over the last several years and has become more reliable, but they still rated them behind the 5.0. They rated the NA V6 models as the most reliable as they do not make enough power to break anything.
One of the other things to look at is the towing capacity. The 2.7 EB is rated at 8400lbs. The 5.0 is rated at 12,900 with the optional Max Tow axle.
All of that said, I based my purchase off of long life and lower maintenance. I keep my trucks for a very long time, and drive my vehicles until they have 200K-300K miles on them. I just sold my Lincoln MKZ earlier this year that had a 3.5L NA engine with 297,000 miles on it. The engine still ran great, the ABS module died and was going to cost more to repair than the car was worth. I do almost all of my own maintenance as long as it doesn't require a lift. I also do 90% open highway driving with a 110 mile daily commute.

 

Same here. There was a video from Royalty Auto Service in Georgia. They are considered top notch. The owner waked around to every mechanic and ask them if they were buying a Ford truck which engine would they buy for themselves. All of them said the 5.0 .... except one. I believe there are 6 mechanics in that shop, so 1/6th of them preferred the EcoBoost. They made the commits about staying away from the EcoBoost for the same reasoning as you and me stated. Long life.
