Detergent Levels in Different Gas Brands.

[steve20]

remember when.... it was still called American? then Amoco--they actually had separate gas lines from the refineries to the depot to the tanker farms for their premium. They used to call what is now BP/Amoco Ultimate "white gas" -- because it was as clear as water when it came out of the noxxle

Ah yes, I remember the white gas of years gone by.
Opps, we're showing our age. lol.

I wonder how Conoco Phillps gasoline stacks up to the others. They say their gas contains twice the standard. Does anyone know what the standard minimum for detergent additive is?

Something's screwy with that article. Exxon/Mobil is the same company and when you go to the website they don't indicate there is any difference in the fuel. Either the levels of detergents in the same gas can vary widely, or the measurements were not accurate.

Don't forget that while Mobil and Exxon have merged I believe the divisions still do have differing standards. I don't think most people realize this fact. That is the reason why there are still both brands operating, sometimes at the same street corner.

Keep in mind that one detergent is not the same as the next. It is tempting to think that more is better. However, without knowing the detergent(s) that each company is using, it is not possible to use the list in any practical way.

By the way, Amoco used to be so proud of their white gas that they put sight glasses on the nozzle so that you could view the fuel that was flowing into your tank. You could even be confident that your fuel was debris and water free since you had the opportunity to watch your fill.

They are measuring detergent levels indirectly by the residue-not mg of detergent-----mg of residue which reflects detergent level

It is actually worse than that. The unwashed gum is essentially everything in the fuel that does not evaporate. It would include all additives that are not volatile and any "gunk" that is dissolved in the fuel.
