Thread: Gull Diesel

Delivery trucks are "flushed" all the time. Spent most of today inside a alloy tank on a truck that had multiple cracks on multiple dividers in the tank.Petrol and diesel mixing etc. Guarantee when it is put back into service tomorrow there will be at least 2 liters of water on its first delivery.(I just weld up the cracks not responsible for the water)

All good, I don't really know jack shit about fuel refining, delivery etc, just heard rumors from the guys that are into cars/engines etc at work. Cheap fuel it is

Sulphur is the lubrication in Diesel.. low sulphur, less lube.
Fine for an older Mech injected setup, but I wouldnt run it in a HP system
We have enough problems with it in Marine engines where clearances are bigger - the wear is greatly accelerated.
Filled up 1.6 million litres last time we bunkered

Never fill from a station that has the tanker truck there.....enzymes fuel tests as good ad anywhere else. If you're unlucky you might get a dose of h2o but most of the cases we see are through poor servicing or filling from drums. Common rail diesel systems create huge amounts of heat so the returning fuel to the tank is hot and ad it cools overnight cause condensation the same ad the windows in your house worse in vehicles with a plastic fuel tank. Try to keep your tank as full ad possible too. And dont believe all the scrap the media talk

Meant to say nz fuel tests as good as anywhere else.

E10 is the 91 regular + from memory we run the prado on it, rang toyota they dont recomend more then 3% ethanol but have never had an issue with 10% Ethanol so said it is sweet as to run it

what sort of runabout are you on Spanners

That was a DP3 Specialised Construction vessel - one of 2 maybe 3 in the world - interesting job when not working on site, but boring as hell once on location.

On a toy at the mo, enroute to Bali to drop it off

Thats Awesome Spanners, i once worked on a stern trawler that held a similiar amount of fuel, we burnt 130ton from louisville ridge to lyttleton, spent a bit a time at sanfords Tauranga as shore engineer for the purse seine fleet, miss the boats but love the farming, enjoy your trip to bali

Not sure about the seals, but the Methanol will mix up with water in the fuel, which won't all get caught by the filter, and can then be bad for the injection system. At least that is my understanding of the main risk, as water in a boat's fuel tank is inevitable.

ethonal produced by the dairy industry is added to gull petrol...

I would put the added savings from less wear from NOT using Gull as being worth alot more then $110- more reason not to use it

Low Sulphur is BAD BAD stuff in modern HP pumps
