Help please.

7.5 litres of PETROL put into a 2002 Mk4 Astra 1.7 Turbo Diesel Estate.

Not by me... but anyway.

It has NOT been started or driven.

I had it towed to a (closed) garage, after being unable to syphon from it - and after refusing the AAs £200 "fuel removal" service. As it seemed insane, seeing as I already pay them to recover me.

Questions:

Is 7.5 litres enough to just brim it (no idea on tank volume) and get by?

Is there an easy way to drain the tank?

Is it likely to have done any damage?

Help frown

tank is probably under the back seats, lift the back seat up and take a look. typically you will need to unplug a couple of electrical connectors, then unscrew the large plastic "nut", this allows you to pull the fuel pump out. then you can simply syphon the tank dry. (this may not be applicable to astra but i have seen loads of cars like this).

If you have only put 7.5 litres into the tank, then fill it with diesel and keep topping it up when it gets to 3/4 tank. It might take a little longer to fire up, but it will be fine and with no damage done.

Sounds fine by me, if you mean 7.5 litres of petrol then fill it up with diesel, it'll be fine. Mate of mine put 25 lt of petrol in his diesel Astra, topped it up with derv and it was OK.

How big is the tank ?

60 litres ? Means 12.5% petrol ?

Is it a common rail engine that one ?

Hmmm I'd be tempted to run with that one and keep brimming for a while. Then when alls said and done fire in some additives to give the thing a clear out.

I remember when I picked up my brand new Fiesta TDCi a few years back. The tank had been filled up to 3/4 full and when I went to pick it up salesman told me when it got to half full fill it up again. Asked why and he said no reason.

I of course was wary and sure enough, the next day it broke down coming home from my cousins wedding. So I phoned the RAC out, guy took a look round car and said there was a smell of unleaded from the petrol filler cap..

Same here. My parents but a 1/4 tank of petrol in there 02 plate Astra 1.7Tdi. Just told them to fill up a full tank with diesel and give it a go and then keep it topped up with diesel. Worked a treat.

I don't know what size the tank is, can't seem to find it anywhere either.

AA suggested 10% was the cut-off figure for bdising the engine if you run it...

Also dont' know if it's common rail, I hate the little berk of a car and never drive / look at it... frown

Help!

Yes, I'd just fill it, use 1/4 tank refil.

<Is it likely to have caused any damage?> As it hasn't been run, the injection system and pipes are still full of diesel as usual, so you haven't done anything to them, when you fill up and start it, it'll start on the old diesel and then move over to the 10?% petrol mix so it'll never get run on 100% petrol.

This ^^. It used to be normal in winter to add petrol or parafin to a diesel tank to keep it thin in cold weather, not necessary now in the UK but I'd bet 7 litres isn't enough to damage the pump if you brim it with diesel.

This is the thing... if it's a bet, I'm not liking the odds of causing ££££££££ of damage by rolling a dice. frown

Then why bother asking on here, drain the tank and pipes and refill with diesel.

Add 500cc of 2 stroke oil, top up with diesel. Drive normally, top up after 1/2 a tank.

While you may worry for the next 5 years that your engine will explode wiping out the population of Basingstoke, it really won't.

I did something similar a while back! I recall 15% being the figure at which you might not wish to take a chance - sounds like you're under that so brim it and keep topping up.

Wow, Mr Personality, I asked two other questions actualy:

>Is there an easy way to drain the tank?

>Is it likely to have done any damage?

Are you already an AA member or was the £200 quid drainage service that price to new members?

Do you know anyone with 'anycar AA/RAC/Greenflag cover'?
Perhaps you could get them to say they were in the car at the time and see what help they can offer?
My Greenflag policy covers me personally no matter what car I'm in - but perhaps not for mis-fueling, I'll have to check.
