Tips on Buying Fuel

[sharky]

The pumps in fuel bowsers and their crude flow meters are most accurate at full flow rates, at a slow rate they will measure unfairly to the customer.

I worked in the industry (Fuel Deliveries) for a while and did'nt know that. Thanks for the tip

So, in effect, if we ran some radiator/heater hoses through the fuel tank or on the fuel return line, we should be able to go further on a tank because the volume of petrol would expand...but how does (or does it?) affect the octane rating in various temps?
I know ...its late.....goodnight

i wonder if mister bishy will have waved his wand and done some magic to get the fuel temp where he wants it prior to injection. might just be acheived by those fuel rails sitting close to the engine between the injectors.

its interesting tho because 70 litres in the tank will not always be the same amount of petrol so how does this affect fuel economy figures. perhaps fuel economy should be quoted as 'miles per pound' or for this more modern era 'kilometres per kilogram' or 'kilograms per 100 kilometres'.

Fuel tanks were normally only buried 600mm below ground level. Up here in North Queensland the fuel definitely heats up during the day, definitely need to buy your fuel early in the day

Really? Hrrm! That might explain why you rock up to a fuel pump which says 'Flow Rate: 5-15L/minute'.. And then spend fifteen minutes with the trigger on the pump pulled all the way in, to put 90L into the car.. Always wondered why the smeg they would wind the thing down to it's lowest flow rate! Maybe they know of this inaccuracy, and are taking advantage of it?

Coincidentally there's a bloke in America working for a fuel company and he delivers the exact amount as in Melbourne.

"...Kinder-Morgan Pipeline here in San Jose, CA. We deliver about 4 million gallons in a 24-hour period from the pipe line; one day it's diesel, the next day it's jet fuel..."

The following sites have done some research albeit from media sources

Wow. So it's not just Microsoft and AOL and cancer spam, there's petrol spam too!

In both diesel and petrol Pajeros (and most other makes) excess fuel is returned from the injector pump / fuel rails to the tank and will eventually heat the tank up quite noticeably. In Diesels the excess fuel circulation is used to cool the pump and the excess flow is several liters per minute.

So if you are pumping diesel one day avgas the next where does the flushing fuel go. Mixed in I suppose and so diluted it does not matter ? Hi octane (cetane) diesel !!

Just goes to show that the email is spam, as there's never just one pipe in fuel-pipelines systems & all the different products are piped separately in separate pipes! What governs what is pumped, is simply 'supply-demand' & capacity to store it at either end! (Notice the typo where someone failed to correctly convert all the 'gasoline' references to 'petrol'!)
The links to the other About webpages are interesting to read;

One point they refer to is the issue of filling up at the servo just after the tanker has refilled it not causing problems but I experienced bad fuel this way (stalling towards the end of an off-road trip 20+yrs ago), plus my latest purchase of a J-top wouldn't have been if it wasn't for some bad diesel!
Lately I've noticed that many older servo-tanks are being dug-up to be replaced (or the servo closed-down), with polymer-lined tanks that won't corrode/contaminate fuel. As they've made late model vehicles more fuel-efficient, they've also become less tolerant of poor-quality fuel.

The fact that the initial blurb mentions "petroline" in the text just screams "find/replace" Gas for Petrol. So it was originally written for idiots in the USA who are suckers for this stuff...

Of course it's 99% bull$hit, why do people believe everything they read without question ??

never seen flushing fluid used on a tanker and I've just spent seven years running tankers.
