The techs at work say that it is sediment from dirty gas station tanks. Considering that I only fill at 2 gas stations, it looks like a change is due.

Any names? Where should we avoid?

Chicken disclaimer - I have no evidence that any of these servos caused the problem, blah, blah, blah.
But I fill at Caltex on Mokoia Rd and the Gull stations at Otara and Takanini.

Do you park mostly inside or outside?
Do you normally fill up or put x dollars in?
How old were said filters?

When you fill right up every time you get less moisture in your fuel tank as the fuel naturally pressurises as you use the juice (less true the more air you had in there to start with). Then when your engine cools down the tank drops a couple of degrees as well this causes any oxygen to contract and attach to the hydrogen samples in the fuel creating water , and oxides to form(from the additives in all fuels), creating the sludge to which you appear to be refering. Parking outside exacerbates this.

If you were on the stock filters they have probably held back the same sludge for many years and just gave up.

Most fueling problems can be traced back to either not filling right up each time or faulty filters, or both.

Having said that avoid gas stations where their physical location is prone to flooding, for the first couple of weeks after heavy rain.

Gas stations are required to test regulary for water in their tanks. Sadly silt forms for the same reasons as above filling temp changes etc but there is no requirement to test for it unless you mention it to them.

I don't reccommend putting half a tank of one company and a half of aanother either as some companies additives will react negatively with anothers.

Not a problem on a cage, due to the increased diameters of the jets. Apparently they can bond with each other as each tries to remove the other from the fuel creating, you guessed it, sludge. I only use Caltex due to my fuel card and only use other companies when it is already in the red.

When I fill up with anything else while my tank already has a half of caltex it backfires or runs rough.

Synopsis: Buy a whole tank at a time and replace your fuel filters if you have not already.
