red deposit on plugs in uk

Back in the 80's Exxon was using something that crated the same issue. Red color in the cards and plugs. Wasn't such a issue but kept me away from using Exxon then...Look at you fuel filter..it looks like a dye or something.

Cool



Thanks for that. Its a bit hard to avoid this fuel round here but will check the filter.

Is it Exxon? If so, they are still at it!! Change to a other brand for "cleaner" burning. The red tint screws up plug reading when checking plugs...don't like that.

It could be Manganese. Also known as MMT. It is an additive that is used to raise octane rating. I don't know if it is still in gas in the states but I remember the red deposits when it was.

Here is one example.

I know we're supposed to keep politics off of this site, on "pain of death", from Wexy, but-

Could the Red colour emanate from the fact that you are Communists? (Socialist equals commie here, apparently, in the land of social security, unemployment, and Medicare) :shock:

I JEST, of course! :waving: The Exxon Mobile theory makes more sense; they are trashing (adulterating) your petrol, so that you'll keep buying new automobiles, perhaps?

This is all in fun, in case you haven't guessed, and the Brits are my favorite people (well, after half-naked Australian girls) :cheeky1::cheeky1::cheeky1::cheeky1:

I don't know about the UK refiners, though I'm sure they follow suit, but here in the States all Market-level fuel distributors reformulate and up the oxygenates in the gasoline supply come winter time. It's usually not alcohol additives that cause the discoloring, but the ether class of additives that discolor. Red is common, but pink, blue, orange and variants can happen depending on the mix.

Hey, at least your fuel supply over there is consistant on mix.

This Autolite chart shows the red:

Pink? Pink is a purdy color/colour...just ask PinkPork!:cheeky1:

PS- I understand you have a bridge/tunnel system, which I'm still trying to put on a route. Silverfox keeps sending me in the wrong direction! :action:
