The gas mileage similar but the 6.2 takes premium fuel vs the 5.3 running on regular fuel. That’s about $20 more per fill up or $1,000 more per year if you fill up once a week and $10,000 more in fuel if you keep the truck 10 years. Maybe not a deal breaker but it does make a difference.

@8020Media Год назад

Certainly does make a difference over 10 years. We were just driving the point that the gas mileage is more similar than people may think. However, thanks for the valuable insight! This will help future viewers for sure.

@demetruesorange5740 Год назад

Maybe $10 a fill up at least in Minnesota where I live it’s like a 40 cent difference.

@Banshee421x Год назад

My friend laughed at this. He said his 6.2 has not seen a drop of 91. He's at 85k milage

@pawg206 Год назад

In 10 years I’ll net roughly 700,000 so not to worry about that

@Banshee421x Год назад

So this truck is only capable of 91 octane and nothing else?

@jimblecha9221 11 месяцев назад

Just sold our 2013 Suburban with 5.3 with 265k for nearly 20% of original purchase price. Kept our 2013 Suburban, 5.3 with AFM now at 161k and bought a 2023 Silverado LTZ with 6.2 DFM. Both get comparable MPG, but the 6.2 (13,300k rated with $850 towing package upgrade) hauls our 7,000 pound trailer with ease compared to the 10k rated Suburban. We live in Colorado and the hills, altitude and heat were a strain on towing with the 5.3 which was really under engineered for towing. Fuel mileage of 21-22mpg is similar with the power advantage going to the Silverado 6.2. Just had our 2nd oil change and expect the mileage to get even better as the engine gets more miles. We’re retired and enjoy the extra comfort, large computer screen and other upgrades. Especially appreciate the towing package!

Had several 5.3s including a 2018 L93. Traded for a 2018 L96 and will NEVER go back to 5.3. Totally worth the extra for premium gas (6.2 does a little better mpg). 5.3 strained where 6.2 is effortless - hard to believe its only 65 hp more...

@Murphturf408 Год назад

Not even mentioning the current pricing and no end in sight on price relief.

@Patroit1776 Год назад

I believe those hp and torque specs on the 6.2 are based on the recommended 93 octane. Where I live in northern MN, it's a 92-cent difference between 87 and 91. 93 is hard to find, and I hear of ppl running 87 in the 6.2, but then you're not getting the most out of that 6.2 that you paid extra for. And paying 70k for a truck that recommends a certain fuel grade, I personally would run 91 minimum regardless of what other ppl say. So that was why I got the 5.3. Yes, 6.2 tows more and performs better doing it, but towing a 6k trailer trailer 6-7 times a year also wasn't justifiable to upgrade to the 6.2. Then, the other 99% of the time, when im not towing, I would have to pay $20-$25 more every week for fuel. And the 6.2 takes almost twice as much oil, premium oil isn't cheap. So, in my thoughts, the 5.3 was more financially smarter for my application.

@8020Media Год назад

Chad - Thanks for sharing your thought process. This could definitely benefit someone deciding between the two.

Oil capacity is the same, other than that I agree

@KK-td2nd Год назад

It's going to be interesting to see the changes to GM's new gen V8 engines for supposedly 2025 new gen trucks. I sure hope they do away with DFM. Another thing is to go back to port fuel injection and do away with direct fuel injection. Direct injection has been proven a poor design across all manufacturers as it leaves carbon deposits on the upsteam side of the valves. Carbon will cause you indigestion if you're one to keep a vehicle long term. Engineers are trying the duel injection. It helps some but port injection is simple and keeps valves clean. Why not stay with tried and proven design. It dosen't have to be rocket science.

@8020Media Год назад

KK - Great points and it definitely will be interesting to see. If we had to guess, they won't do away with DFM.

@27dmarshall Год назад

DFM isn't to make a more durable or refined engine. It's purely to help meet CAFE standards. By 2025, passenger cars and light-duty trucks must meet Corporate Average Fuel Economy (CAFE) fleet standards of 54.5 miles per gallon or face huge fines.

@jimtwombly2109 Год назад

Nice briefing, but I would ditto the Ohioguy. Premium fuel would certainly be a factor in my decision not to buy the 6.2. I understand it is an outstanding engine but if I were to be towing a 13,000 pound trailer most of the time, I would opt for a 6.6 gas or 6.6 duramax and a bigger truck.

@8020Media Год назад

Yepp, I agree. If you need the extra towing that the 6.2 provides then you should probably be looking into the 6.6, whether gas or Duramax.

Something broken all the time. Transmission issues finally just ruined the thrill for me. GM quality has been subpar now since 2012.

Are we sure E85 gets better gas mileage? Ive always read that the ethanol had less energy than pure gasoline, so that E10 and E15 fuel didnt give as good of mileage results as pure E0 gas. So, using that logic, would not E85 perform worse than E0, E10, and E15 gas?

I'd say the torque of the 6.2 helps with fuel milage where the 5.3 will need more fuel to pull it along in a truck/SUV. But what if we swap the engine into a car under 2 tonnes. Will the 5.3 have better fuel economy then? I have a 5.3 I'm putting into a car, I want to add nitrous for added power rather than get a larger engine that will cost more in fuel driving around. I understand I can stroke it and sleeve it to a 6.2 later if im unhappy with the outcome.

If you're trying to add power then fuel economy probably shouldn't be your main concern. More power = worse gas mileage in most cases. But yes in theory the 5.3 will get better gas mileage in a smaller vehicle that weighs less, albeit probably not by a huge amount.

I have a 2010 Camaro SS with a 6.2L LS3 engine. Last summer, I took a road trip to a city 800 km away. I averaged 32 mpg to, and 33 mpg from. I get that the LS3 is a different engine from the L87 in the Silverado/Sierra, but the engine is 13 years old, pushing that car containing myself, my wife, and our luggage for a 2 week cruise.

Steel - Thanks for adding your experience! How many miles are you pushing?

My c7 corvette got great gas mileage too but the car is light compared to a Silverado.

Had an 02 5.3 with factory 3.73 gears. A larger engine would have gotten poorer mpg engine never worked hard unless I was driving with a leadfoot. Borrowed a friends '13 standard cab shortbed silverado. 4.8 tall fwy gear. Yep a real pooch that ones working hard and still a turd. DOnt know why they would put such a wimpy engine in a truck. 5.3 is borderline too small. THe 6 liters tow real well

Are all 6.2s aluminum blocks and forged rods and pistons?

@8020Media 4 часа назад

R - All have aluminum blocks, but not all have forged rods or pistons.

To premium gas trolls: All GM ECUs since bout late 90s have had multiple base maps for different octane ratings, and if MAF then adjusts up from those speed density base tunes. The 6.2 DOES NOT NEED premium gas. There is NO ECU IN EXISTENCE from a major manufacturer that cannot use regular fuel and run out its lifetime with regular. You gota go back to carbureted days of about mid 80s for this. Even early 90s carbed motors are fine running regular. Thats such b.s. and another reason GM is losing luster for old timer purists. Why they recommend this, maybe marketing gimmick? Maybe to keep up reliability or resale price for higher trims? All bullshit.

Mike - Thanks for taking the time to write this.

No one never said that the 6.2 liter engine couldn't run on 87 octane. What is the best octane fuel for the truck. And why would you want to run 87 octane in a truck that makes 300 to 400 plus hp and depends on the truck to tow and your boat or trailer 🤔

@@8020Media yes, many DID say that the 6.2 cannot use 87, hence this post. Start reading comments.
