5.3 v 6.2 daily use and mpg

[B520044]

I have a 21 Yukon SLT with the 5.3 and average 20mpg overall. Slightly more HWY than city commute. On road trip to FL I got 23mpg. Currently have just under 6k miles on it.

I have had both and you won’t regret buying 6.2. It is an absolute pleasure to drive 6.2l engine. If money is no object don’t even think about it.

I got my AT4 Yukon on 10/20 and my wife got her Escalade on Friday. I was completely happy with my 5.3L until I drove hers. That thing screams and the transmission feels smoother to me.

if you didn’t know the difference, you would probably be plenty happy with the 5.3L. It has plenty of power. You won’t notice much of a difference, if any, at the pump except for the premium fuel requirement mentioned previously.

I concur with this. The 6.2 kicks butt

If I were ordering a Tahoe the 5.3 would be great. If I were ordering a burb. I’d go with the 6.2. Just remember that the 6.2 must use premium gas.

5.3 okay on Regular unleaded?

Those are good numbers. I’m also strongly considering a 21 Yukon XL SLT. The dealers seem to be slightly more aggressive on pricing compared to Suburbans out there.

Are you otherwise satisfied with the 5.3?

Regular unleaded is fine for the 5.3.

At first I was disappointed with the 5.3. Just know that I was coming from a Ford Ecoboost, Nissan Titan 5.6 and a Ram Hemi.

Now that I've driven it 6k miles it seems to be just adequate. However the XL should be heavier and would likely feel more sluggish. If I was to do it all over again, I wouldn't have purchased it. I'd wait a year for them to work out the bugs and save the extra cash for the Denali 6.2.

That is not to shabby. Consumer Reports is posting up a detailed review and test results on a Tahoe LT awd November 19th. I will be very happy if I can get 23 on our long road trips to FL. We are averaging around 19 overall but that is 90% city.

I can't wait to read what consumer reports has to say. I am somewhat impressed with my mpg, especially since I always disable start/stop immediately.
