E200 Estate 2011, 2009 SLK 200

The Government is set to change standard petrol from E5 to E10 in September.​

New petrol in September – Is your car compatible?. However it is estimated that over 1 million cars are not set up to run on the new fuel. The new standard contains renewable ethanol which will reduce CO2 emissions and also help in the struggle towards climate change.

Cars produced from 2011 onward had to be compatible for the E10 fuel.

This is from Gov.UK website.

Mercedes-Benz​

E10 petrol is cleared for use in the vast majority of all Mercedes Benz vehicles with petrol engines, except:
  • First generation direct injection C200 CGI (W203), CLK 200 CGI series (C209) of the years 2002 – 2005;
  • Models not equipped with three-way catalysts, models retrofitted with three-way catalysts or produced with a carburettor. These are mainly vehicles older than 25 years.
I'm still not sure if my vehicle is E10 compatible
If you're not sure if you can use E10 in your vehicle:
  • check the vehicle owner's manual, the instructional booklet is specific to your vehicle
  • look inside of the fuel filler flap
  • ask the car, motorcycle or scooter manufacturer
If you're still not sure, use E5 petrol. It will still be available in the super grade at many filling stations.

I thought I had seen this before somewhere...and amusingly it was a Flyin rather than an Old spanner(s) that posted it. :D

And now all merged into one thread. This was the fourth one on the subject…

Hi All

I’m starting to read a little bit about the new E10 petrol that comes in in a couple of weeks time (although did see it on sale today in one of my local garages). Will my 2004 230 SLK be okay using this or should I be switching to the super unleaded which is still E5.

Would appreciate any advice, as what I seem to read from various sources is that the Merc will be fine but the extra ethanol does not do the rubber seals any good over an extended period.

Your SLK will be fine. E10 has been in use in the rest of the world for years and years. I regularly use great quantities of it every 3 months or so when we go to France for holidays. My 2001 E class probably uses more E10 than UK fuel!
My 1993 r129 definitely does.

So yesterday did a little test.
Started in the UK on E5 fuel and drove Northampton to near Bordeaux in France via Eurotunnel.

Average economy for the leg to the train - 30.1mpg
Reset and tested from 1 mile out of the tunnel complex to Rouen - 28.1 mpg.
Refuelled with E10 at Rouen and drove to an hour north of Bordeaux (360 miles).
Average economy 30.1mpg

Whilst not 100% definitive it showed to me that there is little if any difference in economy on E10 compared to E5.

The test car was a 2001 E240 estate fully laden with 2 adults, 3 dogs and a boot full to the roof of 'stuff'.

Big problem for older classic cars that sit with E10 in the tank for months on end this Eradicator 10 will rot the rubber parts inside out in your fuel injection system.. Like fuel pumps, regulators, accumulators and the fuel distributor internals made of rubber, even hoses . You will have a problem with the car , and you wont know were to start. Somthing must be done .. Look at the vintage and classic cars woth a million pounds or even more . The brains of the outfit dont want petrol cars on the road anymore .. what a dam good idea .. pump them with E10 and this way we can kill them of little by little.. We are going back in time with electric toys ...Soon we will be going to work on a horse and cart .. Or even steam .

Been doing a bit of comparison as well with E5, usually my preferred fuel, and E10 and only on a few occasions did I see a difference of any note when driving around town (which is rarely) but that is very difficult to quantify with traffic volumes and the distance covered.
Since then I have varied the fill up and have now decided to stick with E10 for price and no discernible performance or mpg disadvantage.

Well i would not bother either if i lost 5 mpg by uesing E10 istead of engine parts .. if i had my way i would get a large suringe and fill it with E10 and shove it as far as i could up the back side of ther guy who thought about it .

An honest question,
what would be the difference between a little used car that might well sit with unused fuel in the tank, and with the fuel system full of the stuff,

and a car the is used much more and so has the fuel replenished often?

To my mind the fuel sits in contact with the various components either way.

M80 your right But a little new car will be ok to use it . Say after 2000 . The year you car was made will be a big factor weather you can use it or not . Well we all can use it , but damage to the older cars will on the books,, new cars will be fine,, its just the old cars .And to find out if your car can stand the Eradicator 10 google it .

Ive decided that il use superunleaded from time to time, maybe every third fill up, that way any problems with potential degredation of fuel components will be minimised as at least the super juice will combat this? I might be wrong but im sure any of you guys will put me right if im mistaken??
