New Member - 2015 Suburban LTZ v. Denali XL Buying Advice

[cardude2000]

Hello All-

New member and happy to be here. I am in the market for a CPO 15-16 Suburban LTZ or Denali XL. Prices and mileage are similar across the market. I can be sold on exterior looks either way, and will admit that I prefer the Denali cabin, but only slightly more. My primary concern is with regard to the MPG differences between the 5.3L and the 6.2L. The vehicle will be my wife's DD, and will be quite busy shuffling our three kids around town on the regular. Curious as to what experiences owners have had with either motor during daily running, road-trips, etc.

Thanks for the input.

MPG differences are virtually non existent on the highway and 1 MAYBE 2MPG around town.

6L is the way to IMO. But for gods sake dont buy the highest end Yukon trim and then cheap out and feed it anything but premium.

Given your situation, I don’t think I’d care which one if you like them both. Just whatever is certified, meets your mileage criteria, and within your area or wherever you’re willing to travel. I wouldn’t imagine there’s a ton certified to choose from.

You'd be surprised. Within a 500 mile radius - I don't mind traveling to purchase a vehicle we will keep for many, many years - there are 35 CPO's on autotrader alone. Never mind those dealers who only list on their own websites.

It does seem like the mileage on the highway is negligible between the two motors, but I am surprised that so many are saying it is the same around town too. Although...it does seem that it is primarily the Yukon owners who are saying no noticeable difference. Any other Suburban owners able to chime in?

I don’t know if the ‘18 Tahoe is AWD like the Denali. As a Denali 6.2 guy that had a suburban prior I can tell you the 2-3 mpg city difference is being kind. My experience was closer to 4. Simple math says even 3 mpg difference at 1000 miles a month is a good bit of cash. Bottom line is both are great trucks. Good luck.

This gen Denali doesn’t have “AWD” like the previous. It uses the system that the previous gen Tahoe did. So it they have the knob.

The 6.2 is stil quite a fuel sipper in comparison to others. My wife’s GC Hemi is rated at less, V8 RR less, QX80, LX570. Just a few that come to mind.

Neither the denali nor the tahoe are AWD

Sticker ratings have been spot on for me (Yukon Denali). I hammer it all the time and get around 14-15 in town.

I Have a 17 Sub and it will not get the rated mileage around town as there are too many hills, it has the tow pkg with the 3.42 gears. On the Highway though, it rocks, I consistently get between 10.3 and 10.7 l /100km. This is at 65 mph or so. That translate to 27 mpg in Imperial and about 24 in American measure. As others have said, it just boils down to what your preferences are. For me its the little things that I like, such as having the Gas Tank lid on the Drivers side, or for the Suburban and Yukon XL, the bigger Gas tank. Having the HUD is nice as well. Good luck and happy hunting.

Shows how long I’ve been out of the market. Didn’t know AWD stopped with the model I have. Thanks for the correction. Anyone know how the Escalade stacks up on mpg?
