Use the correct fuel to avoid problems
 

Make sure you are using the best fuel for your Benz. A lot of fuels today contain a % of ethanol [alcohol], this is detrimental in the long term to your cars fuel lines, pumps etc leading to hoses breaking down, corrosion, fuel smells / leaks etc

:bow:Personally, I only use BP ULTIMATE [98-100% OCTANE RATING] , NO ETHANOL...

My car is certified to run E85 so the fuel system can handle Ethanol. The 10% alcohol is forced on us in California. The green lobby likes that we are burning the food as motor fuel.

BP is called ARCO in California and contains 10% alcohol and has a maximum 91 octane for the premium grade.

100 octane is almost impossible to make and stay within the emission requirements.

his 100 octane is RON, not the RON+MON/2 that we have here.

I'm in CA, am using Chevron exclusively on the C230. My wife prefers 76. As I understand any premium grade gas is good for the car, but try to stick with the same brand so you don't keep mixing detergents.

As far as I know, 91 octane is the max in the US. I thought higher octanes weren't necessarily good for the engine that's not made for it ... so you are supposed to stick with your engine rating.

I also thought Arco was aftermarket gas around here, something to stay away from.

I will have to check my local BP. I thought all gas sold in the US has 10% Ethanol. The labels on the pump use to say "May contain" because it was only added I think in the winter months? But now they all say "Contains" 10% ethanol.

I usually use Sunoco, Exxon, or BP.

I run hess 93 octane as its US oil.

:naughty:Love your [lady] posts!

As long as you use the correct octane fuel specified for your engine from one of these vendors, you'll be alright http://www.toptiergas.com/retailers.html
