What grade fuel you put in your metris?

 

[howvood]

I use ethanol-free,87 or 89 octane, mostly.

Mine seems to be happy with 93 100% gas, never any ethanol crap.

 

[Greenmanedlion]

I wish I could find corn free gas. Where the heck do you get it?

I use 91/92/93/94, whatever the highest is at that station. I'm more brand oriented. I live in a fairly poor area and most of the stations are discount, or run by the goose- which I refuse to buy from because of their discriminatory labor practices.

Plenty of corn free in Oklahoma We do have one of the largest petroleum hubs in the U.S. Come on down!

 

[Sadragna]

I mostly use 93 I don't think I have any ethanol free around me. Here a link for gas station around the us and Canada that have ethanol free.

Always use what is recommended in the owner's manual.

Oklahoma? I'm already sphitzing and getting mosquito bites here in Jersey! Hey road ghost, you get any corn free stuff up in Winnie?

 

[Road_Ghost]

I'm in Niagara. Closer to you than Winterpeg.

87 until i put the box on it. Now its 93.

I honeymooned in Winnipeg by accident. Personally I think it's the second nicest city I've ever been to (after Jerusalem), and if I could ever get approved for a work visa up there, I'd be on the road ASAP.

The tech at the shop told me to use 87 when it gets really cold (around 10F or so). Might even give better performance. Unfortunately, I don't pay much attention to performance unless I want to get to 30mph really fast.

What is "the goose"?

 

[athlon866]

Winnipeg is close to where I live. I use 87 till my wife told me to follow recommendations.
Mercedes Winnipeg gave me a very bad experience so I didn't buy my metris there.

I've been mixing it up. Some fill up 87, but majority 93. I want 'the box' like Robbie, just trying to put it off.

A conviencece store in the Philly area called " Wawa", which is named after the sound a Canadian goose makes and has one as its logo.

That is the first time I've ever heard that kind of logic on using 87. lol

Use what is recommended as per owners manual.

What is the box?

 

[Greenmanedlion]

It's a tuning chip that turns ones 208bhp/258 lb-ft M274 into something more like the 240bhp/274lb-ft M274, which powers current 300- series MB products (think C300, E300, GLC300), vs the 250 series products (like the CLA/GLA250) which have the same tune as the Metris, albeit with the M270. But the only differences between the 270 and 274 are related to transverse or longitudinal mounting.

I think the difference between the two outputs is strictly a programming thing. However, I'd guess that driven aggressively a 208 would last longer than a 240, (that being true both with this box and from the factory).

Has anyone thought of converting to CNG/LNG?
