How's that GMC Sierra treating you? I will disclose that I'm an immigrant from Britain....so I've never owned a truck. My wife has ordered me to trade in our Acadia for one in the next six months because I've destroyed the interior with all the DIY I've done to our house with drywall, 2x4s, blah blah blah.......always looking for input from people. Because I'm not FROM here, I'm one of the few people who truly has zero loyalty to any particular truck brand....so I'm taking notes.
Well, since you asked, and this thread has derailed, I guess I will respond here. And please don’t let me turn this into a debate, as I truly love the offerings from all the major truck MFG’s. My buddies have F150’s, Rams, and Chevy’s. They are all nice trucks and at the prices we pay, they have to be, or we would not spend the coin.
Here is my truck experience, just to put some weight behind my opinions first.
2004 Chevy Colorado LS Z71, I5 engine
2008 Chevy Colorado LT Z71, I5 engine
2012 GMC Sierra SLE, Non-Z71 5.3ltr Crew Cab
2015 GMC Sierra SLT, Z71, 5.3ltr Crew Cab
2018 GMC Sierra Denali, Magnetic Ride, 5.3ltr Crew Cab
My daily commute is roughly 15 miles one way on city streets and interstate. My weekly towing is either our 242LS, Two waverunners, Two Snowmobiles, or our Arctic Cat Wildcat.
Longest tow was bringing the 242LS back from South Carolina this past April to Dilworth, MN (Somewhere near Fargo. Check out the highlights on
www.biff.org)
We averaged 22.9mpg running superslab down locked in at 75mph for the first 1500 miles. We got 11mpg towing the 242LS the 1700 miles back. I think that was pretty impressive. My best mileage to date on this 2018 is 27.3mpg over 77 Miles. So this was not just riding the wind, although it helped.
One of my buddy’s called BS on me and said anyone can play with the electronics and fake good mileage. And he said there is no way my Denali would get better mileage commuting in town over his F150 with 10spd tranny. So we reset out meters in the morning and did our commute. He shut right the hell up when he saw the video I posted to my YouTube channel the very next day.
23.7mpg commuting to work on city streets. I didn’t rub salt in his wound, when I got over 24mpg on the ride home. So obviously I was not playing the wind yet again.
So you ask, do I like my Denali, you bet I do. Mileage is amazing. I have over 14,000 miles in my first 10 months. Put on over 3200 miles on a road trip with my senior parents and rode in comfort the whole way. It’s no Buick, but it’s the best riding truck I have ever owned. Those jokers that love their Z71 off road, can keep it. There is no need for stiff shocks and rock plates for the average guy. When someone asks what the difference is between Chevy and GMC, it’s not just cosmetic. And that is not a badmouth to Chevy. In appearance there are nearly twins as stated. But factory reps tell me the amount os sound insulation, quality of interior components and in this particular model, Magnetic Ride Control are the real differences. Otherwise twins.
So the last point above, fuel, put in what the engine was tuned for. Today’s engines will adjust for the fuel you put in. You will find that putting in a different octane rating will effect it as it may not have adjusted from the previous octane. After 2-3 tanks, you should not be noticing that “seat of the pants” HP. I noted this mostly when fuel was $4.50/gallon and we switched to E85. When there was a $.50/gallon difference, it was cost effective to use. That was quick math based on the loss in mileage. E85 was great for HP, wow the power. It was truly reflected in mileage. But running 87 with ethanol is the perfect fuel for my truck with the mileage numbers posted above.
Fuel debates are as silly as oil debates these days. A person will put in what makes them happy, so spend your money the way you want to. Me, I will put in what is on the fuel cap. And all of my engines are current technology, so unless I am storing my engine with a full tank, I have no issues with Ethanol. They all work with it and that’s life. I am just careful how I store it, as others have agreed.
Good luck guys! Love what you own and enjoy it. Nobody makes garbage anymore.
