Most automakers, today, consider that within the "normal" range. That's partly because of the relatively loose-fitting piston rings used in many of today's engines, to try and get friction in the cylinders down, for better fuel economy. You can at least partly blame CAFE and the EPA. Looser rings allow more oil, under pressure, to get past them and into the combustion chamber. Today's thinner-viscosity oils also contribute some to that effect.

He said he feels like he's driving a 20 year old truck carrying oil around

But, the buttons are high quality at least and you do learn fast.

IMO, almost anything (even buttons or a rotary-shifter) beats an electronic joy-stick, where the lever pops back into the middle of the range, with a light, no matter what gear you are in.

Eh. I don't believe that because I have too many cars with low tension rings that don't use oil, and 4 of them have 50% more cylinders to allow leaks to occur in.

I mean, it IS a GM truck after all lol! They haven't really changed much that you can't swap around from a 2000-2025 haha!

Jokes aside I tend to always carry oil with my cars anyway, never had to use it but I always bring 1/5th total cap as well as 1/3 quart of brake fluid and 1L of coolant. Probably a waste of time as I've never needed to use it but it's just hanging out under the spare tires

I have never owned a car that used ANY oil. Never once. So this isn't a "modern car" issue.

I have no issues with my shift lever that pops back into the middle.

MUCH better drive today, traffic was similar but I had an excuse to hit 5k rpm leaving my subdivision to make a gap. Way less people bring stupid as well, plus these cars do smooth/relaxed perfectly

Absolutely not, 2 quarts of oil every 5k? I would be down to the dealer with a quickness demanding another new engine. I'm sorry he's had so many problems. It's hit or miss. These GM SUVs are either rock solid or crap. I've had great luck and so have the two friends who bought them as well.

BTW Steve mine doesn't have air either but it does have the fancy dampers. Ride quality is excellent. I rode in my buddy's new to him Denali (thank you, me) that had air and I couldn't tell a difference, not really.

So does my Q7 (like clockwork), but it’s expected due to the combination of supercharging and low-tension rings. No reason for that on an NA V8.

CREC? Mileage? PCVs on those tend to slip into failures and eat oi....

Column shifters remind me of 3 on the tree. Iykyk

Hard pass for me

Coworker dumped his 6.2 Sierra after 2yrs. Torque converter failure was final straw.

Fine, but that is not the issue. The issue is what automakers DO consider enough oil use to warrant replacing or rebuilding an engine under warranty. It varies quite a bit, but a number of them say 1 quart in 1000 miles or so.



I have no issues with my shift lever that pops back into the middle.
Again, though, a number of people do. Consumer Reports has also complained about them. I had one in my Lacrosse, and it was one of the few things I disliked about that car, and found confufing...although the car itself ultimately proved too big and low-slung for my (present) needs.

They gave him the printout of the spec straight from GM and it clearly says 1 quart every 2k miles is within spec

I don't think I have ever even briefly owned a car that uses that much oil, my 4.0T is the worst offender but it only uses 3/4 a quart over 5k.....I may have to buy a low tension ring DI Honda I guess?

I mean, my old Explorer didn't use any oil with 220k miles on it. ES uses no oil with 220k miles on it. I truly have never owned ANY car I have ever had to add oil to.
