| RE: Fuel in America....A fuel filter change
I don't disagree about gasoline being a commodity, to a point. During a tour involving fuels while in the military I was surprised to learn that while there might be a standard for a given fuel type, it was possible for there to be an "acceptable" variation and that variation was sometimes detectable in engine performance. I learned that the variation can occur at a particular refinery refining a particular source of the crude. It was all very interesting.
Regarding fuel detergents. I wish I could compare the EPA minimum requirement (ever how that is measured) against the European requirement against the Top Tier requirement. It is my understanding (and I plead ignorance in advance) that the EPA minimum detergent would not meet a Top Tier and/or European requirement.
Regarding fuel quality produced in this country compared to say Europe I recall reading about "the BMW Test". I located some literature about it: http://www.swri.org/3pubs/ttoday/summer90/qual.htm An enlightening read. Not sure what the truth is today. It's rather elusive when talking about oil, lube, spark plugs, tires, firearms, ammunition and ...

An update to this thread.
I have used Marvel Mystery Oil added in small amounts to the fuel tank for the past 2 years or so after filling up.
I also use Chevron "Techron" Fuel System Treatment when going on longer drives...usually once a year.
Personally, I do not think Marvel Mystery Oil (MMO) when added to the fuel or Chevron Techron Fuel System Treatment are snake oil.

My experience with Marvel Mystery Oil:
When unleaded fuel was implemented in the US (yes I am dating myself) I used Marvel Mystery Oil in my 356 Porsches to improve the fuel and make for healthier valve stems, which lasted longer on the leaded fuel.
This product has been around a long time for good reason.

Agreed...It was used during WW2 for piston-engined aircraft.
Personally, I think it works. |

| RE: Fuel in America....A fuel filter change
I am no chemist. When I look up MMO's MSDS, I find this (which is about what I seem to find when I look up other fuel additives):
POSITION/INFORMATION ON INGREDIENTS
COMPONENT CAS NUMBER CONCENTRATION (wt %)
Naphthenic Hydrocarbons 64742-52-5 70 – 80
Mineral Spirits 08052-41-3 20 – 30
Chlorinated Hydrocarbons 00095-50-1 0 – 1
I've always assumed that the majority of the fluid is simply a carrier fluid for "active ingredients", the lower percent chemicals. But maybe I am wrong. Maybe the Naptha and Mineral spirits provide a benefit too.
Thoughts anyone?

I change fuel filters annually on the 500GE (and most of my other vehicles).
The past two fuel filter changes I have poured the contents of the fuel filter into a bowl to observe the condition and it looks exactly like the last picture I posted on 5/8/2015.
Clean and transparent. I am very pleased.
The ONLY thing I did was continue to run Marvel Mystery Oil monthly (half a bottle) in the fuel tank and on extended road trips with 500GE (More than an hour and a half of driving) I add a bottle of Chevron Techron fuel system treatment. Usually when driving to Key West or Tampa.
It seems that the Marvel Mystery Oil did a great job of cleaning up my fuel system on the 500GE.
