Lol.  I know.  I mentioned the 6.2 because it was brought up earlier.  

 

And a a well tuned 2.7 F 150 has run 12.87.

Some of you guys are ridiculous. The dude got a new pickup, and that’s awesome. Some folks can’t even afford a $5k used Nissan Altima. If he bought a truck to haul limbs from his yard twice a year, so

We get it, Skippy.  We know where you stand on the 4cyl.

Congrats OP - let haters hate. Your rationale behind picking the 2.7T sound logical to me... Not all of us regularly have to displace fallen trees from seemingly major thoroughfares. Keep us poste

For me, I’m a V8 guy all the way, not to much interested into performance mods, did on my 18 6.2 cause I lifted it and needed to recal it so I thought what the heck. I LOVE the no noise and low rpms from driving a V8 on long road trips. I was interested in a Raptor if and when I start having issues with my truck (none so far, knock on wood) but I just can’t get over that queer little exhaust sound coming out the tail pipe, then I looked at the Shelby F150 and it didn’t do much for me, got back into my truck and liked my interior MUCH better. I hope everyone gets what ever their hearts desire but for me, I’m old school, low rpms and a V8 throaty sound will put a smile on me on every road trip. Btw, there are a couple Denali guys on the forums that have done an enormous amount of work on their 6.2’s, spending more time in the performance shop than actually driving it, not for me. I truly believe that running a small engine hard for long periods of time WILL only bring breakdowns sooner rather than later especially with a purchase intention for quarter mile and racing it only comes to mind.

I agree.  I like my 6.2 a lot.  It’s kinda fun to drive for a truck.

Not the most scientific test but when I pull my trailer I set the cruise on the highway to 70mph. On overpasses and bridges my 2.7 with the trailer never downshifts going up. The 5.3 would downshift. Which would mean its downshifting to generate the torque it needs to maintain 70 mph and having to rev higher. Meanwhile the 2.7 is still in 8th gear purring at 1500 rpm at 70 mph.

What are the differences in the transmission? What were the rear axle ratios?

That's what is gonna dictate whether your transmission shifts, not the engine.

I guarantee the 5.3 is geared lower than that lawn mower engine with half the rated capacity.

 

Lower gearing WILL make you shift more to maintain speed, but I hardly consider that a negative on towing ability. Look at their ratings. The 5.3 trucks will tow twice what the 2.7 will.

 

Here's a test.

 

Get a trailer loaded to the max that the 5.3/3.42 will tow, and put that on the 2.7.

 

Now tell me which one feels better.

Wait, you’re pulling 7k# trailer with your new 2.7 4 cylinder correct?

The V8 will want to roll at the highest gear possible for better MPG. Of course it downshifts for a hill.

Your 2.7 won't because it's already spinning high and more revs only help.

But that downshift on the V8 with the gearing it has will give it far more torque than your little 2.7.

Waiting for a shift isn't a measuring point.

Both had 3.42 rear axle. The loaner had the smaller 18" wheels and tires while mine has the 20's. I guess technically mine would have the higher gearing with the bigger tires.

Not questioning the 5.3 having a higher rated towing number. Just stating that for my usual towing the "lawn mower engine" struggled less than the 5.3.

Nope. Just a trailer with load of about 2000lbs.

How is it already spinning high when in the example I gave its only around 1500 rpm? Are you getting the turbocharger and engine RPM mixed up?

      Oil Consumption

      By Chuck FB · Posted

      So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !.

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.

      It costs $5,250 for the Yukon Nightfall option (black wheels, emblems and illuminated black GMC grill badge). What a "deal".

      I keep getting the above error message on my 25 Sierra.  If I reset the infotainment unit (via the phone hang up button) it will work again for a day or 2.   But I dont want to do have to reset  all the time. Works fine in my 2023 Corvette. On both vehicles I connect wirelessly.   I have a Google Pixel 10 Pro XL, phone is up to date.  Any Ideas.  See attached
