Quote from: clackerz on July 22, 2010, 04:44:19I've heard that it's very bad to run a tank to empty (apparently more so for diesels than ULP)?Any truth to this - or do we need Mythbusters?I certainly wouldn't try and do it ...but by my understanding the diesel has a very effective bosch filter (it should be as it retails for over A$100) so I think the risk of damaging the motor with contaminants is minimal.. Feedback on here is that if you completely run out it takes a bit of priming but no real drama..

diesel = good!!

people always say there will be dirt in the tank, but they are just guessing, also most tanks take the fuel from the top not the bottom they use fuel pumps not gravity feed.
i just ment the fuel line comes from the top of the tank not the bottom. like agent said petrol have pump in the tank.i have always filled my tanks to the top and run to the fuel light, unless i'm going on a long trip then i fill right up b4 i leave.

My argument is that fuel is cleaner these days and fuel filters more effective so it shouldn't be an issue.
filth gets in your tank from every other tank the fuel had been in since it was refined! it has a chance to collect dirt ect ect from the minute its made, the pipes it travles in, to the storage tanks its stored in, then the pipes its sent to load out in, then the truck that its loaded in, to the storage tanks at the service station, then in the bowser and finally your tank! dont forget all the tanks are probably mild steel that the fuel is stored in, then water gets in there, condenses at the top of the tank, causes rust that inturn falls into teh fuel so there is another contaminent...just think if 1 grain of dirt got in for every 50L (say an average car fuel tank) and at every stage its handled then thats a lot of gunk over the course of the life of your car...
Good quality gasoline should be stable almost indefinitely if stored properly. Such storage should be in an airtight container, to prevent oxidation or water vapors mixing, and at a stable cool temperature, to reduce the chance of the container leaking. When gasoline is not stored correctly and is left for a period of time, gums and varnishes may build up and precipitate in the gasoline, causing "stale fuel"
Research Octane Number (RON)The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.[edit] Motor Octane Number (MON)There is another type of octane rating, called Motor Octane Number (MON), or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load as it is done at 900 rpm instead of the 600 rpm of the RON[2][3]. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, a higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON. Normally, fuel specifications require both a minimum RON and a minimum MON.[citation needed][edit] Anti-Knock Index (AKI)In most countries, including all of those of Australia and Europe the "headline" octane rating shown on the pump is the RON, but in Canada, the United States and some other countries, like Brazil[4], the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI, and often written on pumps as (R+M)/2). It may also sometimes be called the Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2.[edit] Difference between RON and AKIBecause of the 8 to 10 point difference noted above, the octane rating shown in the United States is 4 to 5 points lower than the rating shown elsewhere in the world for the same fuel. See the table in the following section for a comparison
almost lakes!! it doesnt quite loose octane because its poured or pumped!

The word you were both looking for is: "lose".hahahaha owned!!! yer i guess lakes! because you are mixing air into it, and thats bad for fuel! (as we both know)nitro!!! what do you race? im interested!!!!
In mid-july I am going to put my i30cw into a real test - heading to a holiday drive to Lapland and northern Norway. That'll make about 3000km in 6 days, longest single distance driven in a day will be 850 km from southern Finland to the arctic circle.It will be interesting to see how the consumption figures develop during the trip. I believe that especially the driving in norwegian fjells and mountains will take the figures up, otherwise I do expect record-low numbers 5.0 or less.
