18GLE

Hey! I recently bought a CPO 18 GLE350W4. I was encouraged by quote "2018 and 19 GLEs are one of the most reliable MBs" by Chassis the great. Thank you Chassis!
I am excited to join the W166 GLE family. We all know W166 is reliable, but it is heavy as well. I was wondering what kind of gas do you use for it?
Previously I only use Chevron Premium 91 gas for my old BMW 328, but now I was wondering whether I can use other gas brands.
For example, Costco gas is known to be economic, but would that harm the engine? Can anyone there who has been using say Costco gas for a long period of time share some experiences?

I use Sunoco Ultra 93 grade most of the time. Sometime I use Exxon/Mobil Synergy Supreme+.

I hate Shell with a passion. I had 2 different vehicles where they found water in the gas tank.

We have a '14 ML350 and a '14 GL450. Both CPO's. 67k combined miles on mostly Costco 93 gas. No issues. Of course the only way to truly know is to pull the heads........

Damn really? I use Shell sometimes.....filled up on Saturday.....cost me 62 bux too! WTF?

What’s CPO.?
I have ‘17 GLE that can use E85, any experienced comments welcomed.

Curiously, does it really matter as long as it's premium?

amusa

Really it takes $70-$80 to fill up my GLE400.

CPO = Certified Pre-Owned

Anything below 91 if you run it hard it will start pinging. If you drive it easy and normal. You be fine. I thought all GLE are 91 fuel grade other then the Diesel. Not sure on the Hybrids on what they uses.

DAMN! DC prices huh? Just to give us all a laugh: when I started driving it was .79 cents a gallon. I'm sure some of you older gents can recall even lower prices.

Yeah, DC not cheap but certainly not the highest either. California...ouch!

you can use any "top tier" gas...

recommended by many major car manufacturers... including Mercedes. I use Costco. $3.07 this past weekend when I filled up one of my cars

I also bought GLE 350, 2018. Reliability is a relative term. Yes they are reliable among their own class when compared to BMW and Mercedes past SUV. They can not compete with Lexus and Acura in reliability. So Among German manuf they are reliable. For gas I always use 91 grade from Costco.

This is super helpful! Thank you @whitewagon !
I am shamelessly copy-pasting the "top tier" brands in the article here:76, Aloha Petroleum, Amoco, ARCO, Beacon, BP, Breakaway, Break Time, Cenex, Chevron, CITGO, Conoco, Costco, CountryMark, Diamond Shamrock, Entec, Esso, Express Mart, Exxon, Fast Fuel, HFN, Hele, Holiday, Kwik Star, Irving, Kirkland Signature, Kwik Star, Kwik Trip, Marathon, Metro Petro, MFA, Mobil, Ohana Fuels, Phillips 66, PUMA, QT, Quik Trip, Road Ranger, Shamrock, Shell, Sinclair, Sunoco, SuperAmerica, SuperFuels, Texaco, Valero, Value America, Wow, and Win Win.

To answer the initial question; have used Costco Premium fuel since they became a "Top Tier" supplier....several years at least. (note that "Premium" is 92 octane here in the Pacific Northwest). Never had any issues with Costco fuel. Occasionally will put in Chevron, but cannot tell a difference in MPG or performance.

I remember it was $1.10 on Prem and smoking at fast food and on the plane.

hyperion667

Smoking on a plane! Damn.....going back to the 80's and 90's! According to google smoking was banned country wide in 2000 on planes...but yeah, even that was ages ago haha! I don't eat fast food but do recall eateries asking if you'd like to be seated in smoking or non smoking. Seems really odd that some places make you go off property to smoke these days. Lung cancer is the #1 killing cancer followed by prostate cancer here in the states. Smoking nearly killed me: ask me how I know
