What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Fless]

Don’t forget to lift your left foot up and put your left hand to your forehead like you’re saluting. Even better distance.

Thought for a moment you were going to give us the Hokey Pokey @Rocketman.

Yes, the pistons don't take kindly to detonation!

OK will use the premium.... $ .60 more than 87 octane...

91 octane is recommended by GM. You can run less in a pinch, but the motor will be down on power due to the knock sensor pulling timing, it would feel like you had a 5.3l...lol.

That being said, during our spring break trip from STL to NOLA, then to Destin, on the way home from Destin in rural Alabama I needed gas. I usually run E85 or 93 octane, but the stations I came across only had 89 octane as the highest. I filled up and it ran fine, but I wasn't towing or driving it like a racecar.

Yes the 5.3 6.0 or 6.2(if equipped) requires premium fuel for v4 to work correctly


Ignition Timing is Retarded under v4 the compression ratio is increased enough to dial it back to +11 advanced

in v8 I have seen it high as +36 advanced..with 91 octane fuel .
i'm sure it could max out at +42 with 100 octane unleaded(cost too much lol like 10$ gallon even though it only cost them about 50cents a gallon more to make it 100octane from say 87oct)


this is why most will see the v4/v8 AFM early death on the 5.3 6.0,6.2,....


using cheap gas that is not 91/93oct and not mobil or chevron
(and using cheap oil or going too long between oil changes 4,000 is the max)


V4 is possible at 80MPH at 1900RPM with 3.08 gear ratio I'm not sure how high v4 would actually run but as long as the load is 35%(I think that is the cut off to v8 mode) and under it will run in v4 mode...


the MPG savings in V4 mode is significant... at a steady highway speed... 8-10MPG more on the hybrid unit


18MPG seems the common MPG with V8 with Super E-Assist...

you mean on sale for 37,99 they price matched it
to home depo

it was 30 for the lock (instore price) online they wanted $35


I got the lock that Matches to my tahoe key boltlock brand, I was going to get a matching resse branded but the boltlock seemed more practical Since it matches your CAR KEY


pretty cool imo

so i don't worry about losing the key and having to spend a few hours trying to saw it off
