5.3 versus 6.2

[jay15892]

Who cares about mileage? It is a truck. Get the 6.2. Wish I would have and I'll probraly end up trading my 14 in on a 2016 or 17 with a 6.2. I hear the 6.2 is a real beast and I can't wait to drive one.

My 6.2 gets 20-21.5mpg at 55-65 mph. Above that and it goes to 17-18. City gets 15mpg. I drive with a heavy foot. Why? This thing is a beast and so much fun.

I drove both, the 6.2 didnt wow me enough for the extra money on the motor, MPG and premium fuel the 6.2 needs.

6.2 does have more power(as you would expect) but for alot of highway cruising the 5.3 will be fine. I am happy with

mine and I had a 6.0 before this 5.3

Like the guy ^^^^ said, it's a truck...So who cares if it does 0-60 in 6 seconds vs 8 seconds. If I want to drive fast, I have a a track ready sports car that doesn't float like a boat when I drive over 100mph and it won't flip if I hit turn going 60 mph. If you need to tow more than the 5.3 can handle, should be looking at a diesel anyway. And as the other poster said, I didn't feel enough difference when driving the two to validate the price on something I would not use. I don't use my 600HP car to tow a boat, and I won't use my 5200lb truck to race. But that's just me, and my opinion only really matters to me, just as everyone else's only really matters to them, lol.

 

In the end though, it's all on you sir. You get what YOU want so YOU do not have buyers remorse. If 100 people respond, you will get 100 different opinions.

I drive 25K miles a year and prefer to at least be consious of the fuel costs. But the inner child still wants a playfull truck. The 5.3 has been good to me but its a slug compared to my 5.3 in my avalanche when its going between V4-V8 sometimes. Hence why I asked about the 6.2 feel.

 

There is no 6.2 around me so I have to make up my mind tomorrow if I want it so it can be trucked over. However there is no going back if I get it. So just asking.

 

I expect random answers just not the "who cares its a truck" doesnt really help me make my mind up my 9AM tomorrow.

Now this part is a helpful statement:

"And as the other poster said, I didn't feel enough difference when driving the two to validate the price on something I would not use."

If you couldn't tell a difference in the 5.3 and the 6.2 you prob would be ok driving a 4cyl Honda...lol

 

I drove the 5.3 and then drove a 6.2 a week later, the power difference was noticeable for sure. As said the 6.2 can knock down 20-22 on the highway up until 65mph, up to 70-75 will put you around 19-20mpg.

 

I love my 6.2, premium gas doesn't bother me as all of my cars have required premium. I added a CAI and changed out the muffler, truck sounds great and has plenty of get up and go.

I have both, wife has a 5.3 and mine is 6.2.

The gas mileage of both is similar.

If I were buying her truck again I would get the 6.2.

There is a big difference in power, especially on the top end.

Not only is it more fun to drive, the power is there when you want it.

If you want to trailer it should be easy to decide.

I felt a noticeable difference between the 5.3 and the 6.2. When you have to fill up a diesel, premium doesn't feel so bad. I get about 15 mpg out of my 6.2, mostly city driving.

I have the 6.2 with 3.42 gears and love it. I have seen a low of 14.7mpg driving into a 60mph headwind and a high of 34.9 mpg driving on flat lands with cruise set at 70mph.

Is premium required or just recommended. I once had an infiniti where it was required so just curious.

I test drove a 5.3 w 3.42 gears. My truck has the 6.2 and Max tow (3.73 gears) it is a freaking rocket compared to the 5.3. That said I drive 90% city usually under 45 mph in stop and go. I have just under 2000 miles on it and have averaged 11.2 mpg. But it is hard to keep your foot out of it. I also pull a 9900lb race trailer on occasion which it handles with ease. I did get a tick over 18 on the first highway trip with it but that was with the stock tires. I swapped them out for a set of stock size coopers which are slightly heavier which could also be hurting my mileage a little.

It will run on either reg or premium. It performs best with premium. Your mpg will increase with premium. I tracked it for a while, the addional mpg with premium paid for about half the addional cost.

 

Whether they recomend you run premium or GM says you have to I never paid attention. I just did it.

The manual and gas cap states that it is required. I asked the dealer this question and they also said it is required

Its a trade off---the 6.2 has more power -----I dont think anyone needs to be convinced of that. Its a larger motor that

has more horsepower and torque. That power comes at a cost, the initial cost of the engine and the increase in fuel

cost. Not sure if insurance is more? Perhaps someone here may know. I would expect you would get some of the initial

cost difference back on resale whenever that is the 6.2 should be worth a little more than the 5.3. Bottom line is the 6.2 costs

more so is the "fun" you will have driving it worth it to you? I drove both and chose the 5.3 the extra cost was not worth

it to me. My truck with the 5.3 is rated to tow 11000 lbs(3.73's) and gets 21-22 on hwy. I am happy with it. The premium

fuel the 6.2 wants is what bothered me, the extra 50 cents per gallon adds up. Normal driving I didnt notice much difference,

I think towing 10K lbs or racing or perhaps a lifted truck with large tires the 6.2 would be noticeably better.
