I don’t know where the advantage is with the 2.7. The latest car and driver for 2023 models has the 5.3 doing better fuel mileage on HWY. Maybe low end grunt for light pulling?

For starters, it doesnt have the lifter issues... just sayin

I got my eye on it. It’s an interesting engine. GM burned me a few times with their little experiments. 5.7 diesel, 6.5 diesel. I had a cylinder deactivation engine for about a year. For the first time I bought without doing much research. I dropped it off for exhaust thought I blew it up on the way home. It went into deactivation mode. Thought I had a helicopter following me. Joined this forum found out about that engine and unloaded the truck. I was ready to do some mods being it was going to be my retirement truck. I had a 92 that was already done so I stayed with it instead. That convinced me to stay with old stuff like my avalanche. They just keep getting worse, I’ll pass on the new stuff. I’m curious about the maverick. Time will tell.

I have a hard time believing they saw better highway mileage with the 5.3L. Was it towing?  No load, 4 passengers I see 25MPG+ all day on the highway.

Not that lifters are a problem, that failure rate is much lower than the vocal ones make it out to be. This does have a variable lift lobe with sliding shafts activated by a pin. Pick your poison, they state it is very robust so failure rates should be very low like the AFM system (excluding the bad batches) but you know the few failures will be very vocal as it is a system that makes a simple motor more complicated for fuel savings...

Fuel mileage, cost and drivability; it is a few mpg better overall combined because it is much better in the city. Highway is only one part of the equation, but even then GM and the powers that rate them show the highway mpg of the 5.3 less than the 2.7. Then you have the lower upfront costs and the superior lighter duty pulling power with all that low end torque. For those that aren't self-conscious with the whole V8 or nothing it really is a superior motor in many cases to the 5.3 depending on use (which most if being honest probably fall under).

I’ve been reading about multiple lawsuits over lifter failures. A little or a lot depends if it’s you. I heard the same BS with the 5.7 diesels clunky steering column and bad speedometer s. It usually comes to a head down the road.

Yeah I just read it. Maybe I typically stay below 75 on long trips and that’s the sweet spot. My foot is heavier in the city getting the truck up and moving so I understand the 2.7 isn’t great in the city but on the highway I’m pretty happy with it.

Interesting on the C&D report. 

 

Lower initial price, 4 fewer rotating connections and stuff to break to cause issues, including burning fuel.  I suspect that if geared properly and RIGHT SIZED for the towing need the L3B does as well or better than the old technology.  Towing FAST will kill MPG. 

 

As Grumpy shares his Dads and my 52' Ford 239 CI flathead V8 did just fine when geared right.  

 

We are so spoiled by technology and driving like lunatics anymore.

I'm at altitude ( 9000' msl)  cold, hellacious winds, snow, mud, rocks, in and out of 4WD burning E15 that is 86 octane min and get 20-22 overall average.  In ideal low country 2WD ops with 87 octane E10 crapfuel it easily gets 25-28  mpg avg on highway in a 2022 LTD Trail Boss.  I drive 60-65 mph on hwy unless its I-25 where I run 75 mph.

It could be something simple like gearing. You would think Car&Driver would make things equal. I remember reading spec sheets years ago you could actually get a tow package with a 5.3 that would rate higher towing than the 6.2. With the TQ rating and where it reaches max TQ. The 2.7 should be able to use a taller gear. And get good mileage. Empty anyway.

For all the L3B fans.....latest oil sample taken with great results but it had to be topped up with Renewable Lubricants 5w20 HD low ash because I was out of RLI.  Look mom we stopped the aluminum wear.  Still in SAE grade too. The RLI products are tough and made in America by Mom and Pop in Griggy OH.  

 

Currently has a fresh load of Havoline ProRs 5w30 which is working quite well in cold here.

Interesting that the water went up so high.  Is this due to the colder months?  At least the FD stayed down.

Everyone comments on my 1993 7.3 NA diesel f-250 in town. Lots of offers to buy it, and lots of comments on what a great tow truck it is. The fact is I have towed some pretty crazy stuff with it……slowly. It is do to gearing and suspension. It had 185hp and 388ft lbs of torque new. My 2.7 trailboss kicks it’s butt power wise and comfort ect…. We are truly spoiled now a days.

    • I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

    • What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.
    • People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.    
    • Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.
