87 octane vs 91 octane

[olyelr]

40 something thousand miles on the wife's '16 Denali and we have never put anything other than 87 in it. Never had an issue with any spark knock, and the thing consistently gets around 20+- MPG driving around town.

When you say town, you must mean a lot of rural roads at ~40-50 mph without many stops. I live in a city, and no matter how much I baby it. I'm never going to get close to 20mpg. We have traffic, and a bunch of red lights or stop signs every where we go.

Correct... kind of. Mainly 55 MPH roads, but no highway/freeways. Small amount of stop and go city type driving mixed in as well, but certainly not a tank-full of it.

good thing you dont drive in NYC. some places u can barely go 300ft without hitting a stop sign. city speed limit is 25mph and highway is 50mph

That's like idling all day, I'd be lucky to get 10 mpg in the big apple! My wife wants us to drive up for her Dad's 70th Birthday. I don't mind driving my truck up there, I do mind some jerk trying to steal it or something out of it. Should I insist on a garage when visiting the Bronx?

Depends where in the bronx you are going. I think you’d be hard pressed to even find one there. Manhattan on the other hand, garages every block but you pay a premium for a ‘large suv’ i leave mine on the street when we go to the city.... and our trucks are a dime a dozen down there....

I think my wife said that my FIL has a garage in the back of his house, will have to check. They are between cars because their last one got shot up by the cops who were chasing a bad guy.

There are probably more Suburbans per square block in NYC than most cities. But things do happen sometimes. Just don’t leave anything visible inside.

Lol, i dont even leave a phone charger in the outlet... no excuse to bust my windows. I know if they want it they’re gonna take it but that’s just my paranoid way of thinking and that’s why I have insurance you want the truck take it I’ll go get a new one
