Bro, I spend 50$ on a tank of gas @ 93 octane. And I'm thinking about moving to racing fuel!

BoBcanada

here's a funny story, My friend back in europe rented a car and filled it up with diesel lol then what he does! HE STARTS IT UP, AND DRIVES IT TO A MECHANIC, with clouds of smoke behind it... then the mechanic took something apart not sure what, cleaned petrol pump blablabla... bottom line he returned it back working...but paid quite few extra bills

Well speaking of a lack of skills i guess you missed the how to read day in school as well. the quotation from the manual was already posted above and I guess that was missed.

FYI mb is known to test the fuel in the fuel system if they suspect poor gas could cause an issue. If it reads anything less than 91 oct they will not pay for the claim and leave you will the bill.

I may be mocking people here but is 500 bucks a huge deal to a person who has 2 cars that are 60k+ in price? Thats what half of 1 of your monthly payment for the BMW and or MB?

It has been proven that the car makes less power on low grade gas and it dials back timing to keep the car from knocking. Im not a fan of slow AMG cars and a knocking motor leads to a blown motor.

A friend made the mistake of advancing the timing on his MB competitor and his motor exploded in royal from a while back after only 2 years of use. Sounds like the knocking motor could be an issue after a few miles.

i can call people who dont bother to read the OM stupid. what kind of idiot makes a $50k+ investment in a depreciating asset and then doesnt even bother to read the OM or follow its guidelines in favor of saving a few pennies. we are talking about MERCEDES f*ing BENZ here, the engineers at mb are smarter than you or i. they would NOT specify 91+ octane if it was NOT necessary. just because you cannot here pinging does not mean that you are not damaging your engine. i suggest you roll down your windows and go find a nice long uphill tunnel, apply full throttle, and come back and tell us what you here.

i spent almost that much on dinner in vegas last weekend, and i dont even drive an AMG yet. wow.

05C55

You actually had to pay for dinner in Vegas? LOL

CynCarvin32

are you one of those people that thinks they get free stuff when they go to vegas? let me guess you never go in the red and the casinos love to have you back day in day day out to give you free things. go down 2k at the tables and get a free 300 buck room and a few trips to the buffet-- sounds like a fun time to me!

The dinner was not in any casino... the food was far too gourmet to be given away for free.

05C55

IMO the best restaurants in Vegas are in the Casinos. Yes I was down $300 in cash last time I was there in February, but that was the total cost of being there for three days. The time before that I left up a $1000 and stayed and ate for free. I am definetly ahead, my worst weekend I left down 3K and my best I left up 12K. It has become a cheap place for me to hang out.

You don't seem to understand the comp system, you do have to charge the meal to your room, its not free, it is only comped after the fact. And for the record I am not talking about the buffet. I'm not a high roller either, I never take more than 2500-3000 with me.

You are very amusing though. I'm not sure I have ever had a dinner tab that I was responsible for that was over $500.

schwarzwagen

so you are a woman? that explains it.

i'd like to see you walk into joe's and get comp'd.

free salisbury steak at the silverton for mr. 05c55 :p

05C55

If you would lend me your car they may take pity on me and give me a freebee. :p

i have received nothing but complements from some rather wealthy people regarding my w126, it has class and is in immaculate condition. every week i consider a new car to complement the w126, this week it is the 964 turbo.

CynCarvin32

take it easy budy. i had a c32 and now have a daily driver C230k and lets say the C32 and C230k never really got a second look from many people. Its a good car but its not as flashy as you make it sound. Id say the SEL attracts more looks based on its condition and age tested class.

7 series? well thats flashy but also down right fugly.

Nissan Truck? Well it does look kind of nice. Better than a ford or Ram.

05C55

He's dishing it out. I agree however I do get a lot more attention with the 19"s but it still goes relatively unnoticed. My wife drives the 7, looks aside its an awesome car and unlike the Mercedes has yet to see the service drive except for a flat tire.

schwarzwagen

i think we are forgetting the point of this thread. the question was will mid-grade gas hurt my car because i accidentally put some in it. the consensus was, no it will not hurt the car but you should follow the guidelines specified in the OM regarding the subject. which was: drive slowly, do not use maximum throttle, do not over rev, etc.

however, you disagreed (which is fine, if you have the facts), suggesting that mid-grade can be used long term and that in your experience, you have seen no ill-effects. one MUST keep in mind that you lease your cars and get rid of them before any real long term effects are made apparent. basically, you have been lucky up to this point. you sparred with improviz and lost the argument. now you are attacking my chosen mode of transport in an effort to make yourself feel better. i get that a lot, so i will not get angered. when people are on the wrong side of an argument they resort to schoolyard tactics. making fun of my sig, my car, etc.

05C55

Improvis is a ****ing idiot. I don't believe that even 87 would damage a motor with prolonged use. The cars ECU will sense predetonation and retard the timing. You will lose some power and mileage may suffer but damaging the motor is very unlikely and neither you or improvis or anyone else has proven anything to the contrary.

The owners manual are the the guidelines set forth by Mercedes, they are not proof that lower octane will damage the car. Get real. I showed info that clearly stated that late model cars with advanced ECU's can easily protect the motor from predetonation. Most of the cars I have owned I have driven for 50K if they are not damaged by then I well so much for your guess work.

Unlike you I have personal experience with numerous high performance motors, some 100+bhp/ltr powerplants. If anything these high revving, high compression motors would let go first and I have never even heard an errant ping let alone knocking.

Geez you're not even a good internet warrior.

Stiggs

Who is this retard?? I'm talking about you 05C55!
You bought a mercedes.....put good gas in it you fool.

schwarzwagen

heck with it, you are a lost cause. 50k miles is hardly even broken in yet. try 270k miles and get back to me on how many engines you have consumed.

Improviz

I would argue that the fokking idiot is the moron who continues to argue a point he long ago lost.

You haven't provided any documentation to prove the nonsense you keep blathering, because none exists. And like the sneaky little weasel you are, you intentionally omitted pertinant portions of the gasoline faq to try and prove your point, only to have me slap your pompous *** down with the questions and answers from the faq you deliberately omitted.

Your parroting "it's true because I say it is!!" 50,000,000 times doesn't make it true. In your idiotic, stubborn refusal to admit the facts that have been plainly lain out before you, you have established beyond any shadow of a doubt that you know nothing about cars and care even less about them. You have not presented ONE citation from ANYWHERE which supports either of your central assertions over the course of this argument. And you can't, and you know it, because no such evidence exists.

So instead, you start trying to change the subject and obfuscate to mask the fact that you got *****-slapped.

Well, you know what, Einstein? MERCEDES BENZ DOES BELIEVE IT!! If you'd pull your arrogant head out of your *** for long enough to actually read the owners manual which came with your car, you'd see that.

I believe that quotes from the Mercedes owners' manual warning of engine damage if fuel not meeting the engine's octane requirement is used, and that they would refuse to honor the engine warranty if such damage occurs, along with quotations from the gasoline faq, and other sources, which plainly show that it can, constitute proof that any idiot could understand.

Which rules you out.

Yes, folks, it's true: in idiot-land, the manufacturer plainly stating that only premium unleaded should be used, that low-octane fuel can damage the engine and that if it is accidentally put into the car protective measures should be taken, and that they will void the engine warranty as a result of any damage in such a case, does not prove that lower octane fuel will damage the car.

In the real world, they do.

Yes, folks: you should ignore what those pointy-headed Mercedes engineers say and listen to 05C55, a tightass too cheap to put the proper fuel in his $100K plus worth of cars so he can save the price of a good steak dinner over the course of one year. Or, as someone pointed out, a nice, fresh cookie per tankfull. Why? Well, because 05C55 has personally taken each and every one of his cars' engines apart and inspected them for damage, obviously!

Yeah, sure you do....which is why you're sitting here telling us that the engineers who designed them don't know what the hell they're talking about.

Moron.

05C55

Notice they use terms like can damage teh car and should such damage occur. They are making blanket statements. Not guaranteeing your motor will melt down. Of course I'm not a hypochondriac either so maybe your perspective is a bit different.

Improviz

...unfortunately, people can simply read their manuals and read what Mercedes wrote.

For starters, the claim that they stated "should such damage occur" with respect to engine damage related to low octane/poor quality gasoline is a complete fabrication. Nor are they ambiguous in any way, shape, or form about what fuel should be used. You seem to have missed one very important little phrase, so I'll highlight it for you, in a bit more noticeable font: Here is what Mercedes did write, in the owners' manual (which you will find, still pristine and unreferenced, in your glove compartment):

It goes on to say:

Spin and twist all you want, dude...the fact train has left, and you missed it.

CynCarvin32

omg

that about solves that

05C55

I'm not spinning anything. And for the record, the C-classs Manual which you refer to does not even list the C55 does it? The C-class compression ratios range from 8.7 on the C230 to 10 and 10.5 on the 320 and 240 and 11:1 on the C55. MB puts the same disclaimer on everything they produce regardless of the compression ratio.

05C55

Now that I am actually reading the manual you have completely misrepresented the facts.

Quote:
Damage or malfunctions resulting from poor fuel quality or from blending specific fuel additives are not covered by the Mercedes-Benz Limited Warranty.


The above statements pertain to fuel additives, if you have in fact read it or want to look again, this is under the heading of Gasoline Additives page 435 and makes no mention of octane ratings and the term poor fuel quality is referring to the "lack of availability of gasolines which contain these additives" and the build up of carbon deposits which can lead to engine performance problems. Funny you didn't bother to mention any of this. The section on Fuel Requirements page 434 which clearly states "only use premium unleaded" makes no mention of any ramifications to the warranty or damage to the engine. Apparently reading comprehension is not your strong suit. Unbelievable.
