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

Regular as in 87 octane or Premium 92/93 octane?

Us peeps with Denalis gotta run high octane, so I always compare the price of E85 to Premium.

Around here, cheapest 93 octane is at Costco, $3.75, otherwise it's around $4.15 at other stations.

I would've filled up at Costco because their 93 is only 30 cents more a gallon than the E85 I got, but the boy has my Costco card

I've never heard regular applied the the highest octane available.

you refuse to go inside a sams?

weird

It’s Walmart just bigger and I don’t go shopping..

I have an ‘app’ for Sam’s club. Don’t need the card to shop, i scan with my phone and then hit pay when I’m done and it gives me an email receipt and a QR code to show the guy at the door. I don’t have to talk to anyone in there except the guy at the door checking my QR code ( not that there ever is an employees to talk to because on 15 registers there are 2 open) and for gas I just scan the pump fill it and go.
Ok now that I said all this my wife really has the app and told me about what she does…..I refuse to go in there.

Yeah, we have a Sam's membership also, mainly because there is one next door/attached to my wife's Walmart and she goes over there to get supplies when they have events or fund raisers. She told me about being able to checkout through the app. Costco needs to get with the times, lol

Let me clarify, I didn't know if you meant regular "87" gas or "regular" as in "non-E85" gas.

Agreed. I *hate* having to carry yet another card in my wallet because I can't use either an app on my phone or Apple Wallet at Costco. That's almost reason enough for me to switch to Sam's but there isn't one close to us.

Is there a standard procedure for this? Mine is way overdue. What needs to be protected?

I have done it for years, engine off. just don't spray directly in the alternator or close around the ecm harness, I don't cover or protect anything. usually I pre spray with purple power all over to get any grease off. I like to do it while the engine is hot so it just steam drys for the most part. Everything has seals so no big deal

Careful with aluminum around that Purple Power. It literally eats it up. Doesn't happen immediately, don't let it sit for a long period of time.

Ya that stuff is pretty strong I only apply it right before rinsing it, works great on grease

I've only used Simple Green in the engine bays. Is this Purple Power stuff better, easier?
