6.2 LTS Motor worth the $$$$$$

[reardiff]

Coming from a 6.2 owner, I absolutely love the power and MPG's for it's size but one thing to consider is the 6.2 really should be run on premium gas (93).  Around here 93 octane  is about 80 cents more per gallon than regular 87.  That is just over $19 more per tank than if filled with 87.  Or think of it this way if you average 18 MPG over 50,000 miles that would be over $2,200 MORE just for the premium. If that doesn't bother you then I say go for it, as previously mentioned outside of these costs there's really no downside at all,  (other than maybe finding one) just extra power when you want it.

 

I only use 93 as recommended by the owners manual, but you could use lower which risks denotation (i.e. knocking), poorer fuel economy and less power. If you paid up to get the 6.2 no sense in cheeping out a few bucks at the pump is how I see it.

I’ve had all 3 engines in the current gen. (4.3 then a 5.3 and now a 6.2). If it’s in your budget go with the 6.2 and don’t forget to factor in premium fuel. If it isn’t in your budget then buy the 5.3 and don’t test drive a 6.2. Ever. 

 

The jump from the 4.3 to 5.3 was nice and all but the 5.3 to 6.2 was unbelievable. That 4.3 doesn’t get a lot of credit. Remove the AFM and it’s stellar. They should be putting that into Colorado’s and Canyon’s- but anyways I digress.

You really are something. That’s neither car you mentioned. Any farther conversion with is just a waste of time.

Unless, I agree with you. No disrespect, I’m no expert in what you drive and obviously nor are you with what I drive. I do have experience in being a passenger in an old souped up 90’s truck a buddy of mine had but nothing worthy of the time it would take to write about it. I know that once we’re gone we aren’t taking anything with us (ever see a UHaul behind a hearse? Denzel Washington) so better enjoy what you can now.

I paid about $62 for a fill up today on 93 octane. It’s well worth the difference in cost and gives you a lot of smile per mile.

I own a 2018 6.2 Centennial. I traded in a 2012 5.3 Suburban. I have tried running 92 and 87 octane in both. My personal opinion is that the 6.2 is well worth it, and i won't switch back unless I have to for some reason. I found even a 6.2 running 87 octane seems to respond/drive better than the 5.3, but they are different weight trucks and transmissions. My experience with a 5.3 is that it is the smallest practical engine they could fit into these weight trucks. It relies much more on gearing to keep you at a steady pace (towing or not) and leaves the transmission always searching for the right gear, or the driver always feeling like the truck needs "just a little more throttle". My experience with the 6.2 is it just goes the speed I ask it to, and makes it seem like its easy for it. 

 

Interesting list based on the topic too:

Entirely up to you OP, no one else can tell you yes or no if it is worth it. You tow heavy often in steeper areas yeah it would be worth it. For a normal DD with the occasional tow/haul at $1500 or so it is if I am not having to up packages (which I would as I am not a box checker/leather fan so it would require a bigger jump in price) but at $4k it wouldn't be worth it to me. Coupled with the recommended premium (you can run regular with a small premium of about 1-2 mpg and about 20 hp which you wouldn't most likely notice unless told) but it adds up. Regardless of what a few say it doesn't get better mpg than the 5.3 nor is it some rocket ship. The 6.2 is lucky to run next to a V6 Camry or Accord and will get walked on at the big end as well as by other mid-size sedans, so it isn't "fast". If speed is your thing have a toy car, can do a lot more with it and have a ton more fun. 6.2 owners sometimes come off like Tundra/Ram owners do with their 5.7 trucks in terms of thinking they are fast, they aren't. Just do your own homework and decide what works for you. Even if the 6.2 was an option with the LT I probably wouldn't have gotten it, better use of the money elsewhere especially at $4k and personally wasn't feeling a massive difference in power in test drives. Don't get it twisted, the 5.3 moves out well, if you can feed it some corn it is even quicker and closes the gap more on the 6.2 which is a pretty sweet motor but certainly isn't on some pedestal people make it sound.

 

Here is the 5.3 with the 3.08 (figure a little better track time with 3.42's) on pump gas vs E85 (which adds 20 hp and 0.4 seconds and 3 mph in the 1/4 versus pump gas). If you want numbers to compare to the 6.2 it is around 350+ to the wheels and 14.3 at 97 in the 1/4 on 93 so you can do the math on the difference in the 3 runs. Good luck with what you choose.

I fed enough corn to my 5.3 and didn’t do anything but smell like Doritos. I lost lots of mpgs using E85 which in the long run I started having performance issues, took it back to dealership with under 20K and found rust in fuel lines. I was told I may have gotten a bad tank worth of fuel, E85. Yeah, no thanks! I didn’t buy a truck to be constantly searching for gas stations or looking to run E85 where ever you can find it in order to have more performance, I bought my 6.2 to fill the gap that was in need of immediate power when needed with exceptional towing for a half ton truck. You don’t compare a Camry or Honda to a full size truck in trying to keep up, it’s not about that. Forums are full of critics and Trolls but one thing is certain I’ve got a whole bunch of smiles for the miles I’ve driven. Btw, I’ve had people ask me if my truck was a 6.2 cause of the take offs without trying like I had to raise my ass of the seat flooring it with my 5.3. I speak from lots of experience owning one. Test drive one and you’ll want one over the 5.3 any day.

If I was towing I’d buy a 3/4 ton. In my research the 5.3 was the best paired with the 342 gear and fuel choices. In town I could get E-85 for the bump in power on trips I could run reg gas. Your right about the Camry I own one. I bought it just for trips. I know I’m in the minority, I’d rather daily drive a car. I daily drove a truck for work for 40 years, as much as they try you can’t match a car for long distance cruising. I’ve spent plenty of time in both.

Ok one last time. I appreciate your concern I may be deprived of life’s pleasures. When I get up in the morning my biggest choice is to decide if I want to drive my economy car, sports cars, sports sedan, hot rod truck, or my year old trip car. The last one a Camry I use to drive from Texas to Myrtle beach 4 times a year to my condo on the beach. I get a trip vehicle every two years. Last one a 15 Santa Fe, before that my 14 GMC. My father in law lives in fort Bragg so I bought the condo to write off the trips. Have good tenets in my rent houses so I go on many trips. So I do what I want, thrifty is not cheap or for lack of money or enjoyment. I hope that relieves your concern.

LMAO! No really, please stop, you don’t need to get into all that. I’m not going to get into a pissing match with you, it would be ridiculous and nothing would come out of it except people would find out who I am or know what I do. Stick to the subject. People don’t buy trucks cause they like to save fuel or think about using E85 and especially don’t buy 6.2 trucks cause they want to be efficient. “We” buy them because they’re awesome to drive and look great for a truck.

Thanks, Always going to have Trolls jump into a conversation cutting down the newest and greatest technology cause they don’t find it financially feasible to have one of their own, though they have zero experience owning one and make stuff up in order to persuade people not to have it out of spite and envy. Internet is full of them!

From all those i know with the 6.2 it is the way to go.

 

GM is raking in the $$$ on the 6.2  There is no way there is that much of a difference in manufacturing between a 5.3 and 6.2.  I'm sure every time one gets purchased the bean counters at GM just smile.

Heck the "bean counters"at GM smile everytime a full size pickup truck is sold, whether 5.3 or 6.2. Its their highest profit line of vehicles.
