need some advice on fuel please, got a new torana couple of weeks ago, had a full tank of fuel, filled up with 98 once,drive ok, then i put it in to panelbeaters where it sat for a week, when i got it back it coughed and spluttered most of the way home, gave it a good gutful and it seemed to fix it. filled up again with 98, then it has sat in the shed for a week, drove it again today and it was terrible, drove it coughing and spluttering for 10 mins, my question is , i think it is the fuel mix so do i need to add anything to the fuel, or is it possibly just something else

Sounds like you may have water in the fuel?

It's not so bad when it's all stirred up, especially with some ethanol content (which absorbs water), but after it sits for a week the water (being heavier than petrol) settles to the bottom of the tank where the fuel pickup is.

Normally I'd say it'd have to be the petrol station that has water in their tanks, but as you've only had the car a couple of weeks you don't have a good baseline to say for sure?

The proper way to fix this is to drain and remove the fuel tank to clean and inspect it, possibly use one of those "treatments" that coat the inside if it's rusty, then flush the fuel lines and change the filter(s).

Or the bush mechanic's method would be to run the tank down until it's under a quarter then add a litre of metho. But don't let the metho sit in the tank for any length of time, once it's in, go for a drive to slosh it around and run the tank as dry as you dare, if you've got a good battery and a jerrycan of petrol with you, you could even run it out altogether, then fill it up again WITH GOOD CLEAN FUEL.

BP Ultimate is my first fuel of choice, these days I'll drive out of my way to find it. If you look at the composition of all the different brands of fuels in their MSDS you'll see it has almost no additives (see BP Ultimate sheet here) but it comes down to your local area and what kind of choice you have too. Caltex Vortex 98 would be my second choice (MSDS here).

Shell V-Power on the other hand...

Contains Benzene, CAS # 71-43-2.

Contains Toluene, CAS # 108-88-3.

Contains Ethylbenzene, CAS # 100-41-4.

Contains Naphthalene, CAS # 91-20-3.

Contains Cyclohexane, CAS# 110-82-7.

Contains Tri-methyl-benzene (all isomers), CAS# 25551-13-7.

May be dyed. Red.Purple.

...I would have to be REALLY desperate to use!

Either that or dirt in the tank, maybe a clogged filter or even your fuel pump could be on its way out. Check around the fuel pump for leaks. Mine would leak upon start up but then settle down after a minute or two. When I'd reverse out of the garage I saw fuel on the floor and thought it was the hoses, I'd tighten them and it'd be alright but it was a crack in the pumps diaphragm, it'd expel fuel that built up overnight upon start up.

thank you thank you thank you, i did the bushmans method as i was a little uncertain about removing the whole tank. i drove her to 0 on the gauge, filled with 1 litre metho, then drove around my paddock-for a hour!!- she stopped and started a few times over the hour until finally she stopped and wouldnt start. i made sure i kept trying to start her and pumping the pedal to get rid of all petrol. then i put in bp 98, and got her going again. on the way back to the house she stopped again twice and it didnt seem like there was any difference. put her in the shed for the day , tried to start her the next day and she wouldnt idle just kept stalling, left it, done the same the next day, same thing, no idle, tried the 3rd day, stalled a few times, finally got an idle,so i took her down the road, one miss in 1st gear and that was the end of it and now she is running perfectly again!!

thanks for your help

No worries, it certainly wouldn't hurt to change the fuel filter(s) now too.

Ah okay, that was probably half your problem to begin with then!

If it's just the standard mechanical fuel pump and carby setup (not some wiz-bang high pressure electric job) then something like your typical Ryco Z14 would be ideal.

Just mount it in the engine bay between the steel fuel line and the fuel pump. You can either cut a section out of the original rubber hose or (from memory) they come with a couple of short pieces of hose and some spring clamps.

If I were you, I'd buy two while I was there and throw the spare in the glove box, it might take a couple of filters to catch all the crap if the tank was really dirty?

I decided to give it a listen, he could've condensed that so much but yeah, I use 95, the local carb specialist who's been involved in racing for many years told me to come back after I've run at least a tank full of 95 to flush out any 98, he tuned it and told me to stick to 95.

There has been a great deal of good advise offered. I mainly restore and play with our Vintage Tractors. If I don't completely fill the petrol tanks after play I get condensation in the tank which then can end up in the engine and we all know what happens if too much water gets inside.

I always use and run 98 with no problems and on the old engines that have not been rebuilt I use an additive to help the valves last. A fuel filter is a good insurance policy and I have fitted one between the chassis and the fuel pump so it saves water and dirt from getting into the pump and carby.
