SOURCE: petrol instead of diesel

Hi

This is not quite recommended, and to do a 100% job, you should really drain the tank, and refill with just diesel, and renew the fuel filter.

But if it is running acceptably, drive it gently, and keep refilling with diesel.

Good Luck !

Don´t forget to give me a FixYa rating please.

Hi taliesin_dur, You need to purge all fuel related aspects, how long did this vehicle run on gas? fuel filters ,lies,injectors etc must all be bled,let me know how you make out good luck

SOURCE: Chevrolet captiva 2.0 lt poor mpg captiva has

I also have a Chevy Captiva 2L Diesel but with the auto box. The MPG on that one is abysmally bad! I bought it a few weeks ago with just under 30K miles on the clock (2007 model), and it returns around 230 miles on a full tank! That's around 17 MPG and probably on par with a Hummer!!
I was expecting the auto box to be less efficient than the manual of course but not to consume twice as much. Anyone out there with any ideas as to why this could be? I was actually already checking under the car to see if it loses fuel... We live in the suburbs and our trips can be considered a mix of urban and extra urban (they are admittedly on the short side and from a cold winter start; still, this doesn't justify the extremely low MPG). The car seems adequately powered for its weight and considering the small'ish engine and auto box.
Thanks!

Try changing the fuel filter. If that does not help, have someone test the injector pump for pressure. Last would be a compression test on the cylinders. Drain oil and replace oil filter very soon.

What has happened is the diesel fuel is a lubricant and gasoline is a solvent. As gasoline is much thinner, it could wash down the cylinders and get into the oil pan thinning the oil and ruining the bearings. This would be the reason to test the pressure in the cylinders to find out if you lost compression with the rings in the cylinders.

Next, the injector pump for the diesel has seals and tolerances for inside components. Again, since gasoline is a solvent and not a lubricant, the internal parts could be worn out by not having diesel fuel to lubricate the injector pump parts.

If someone working at the fuel station made this mistake, all the costs should be paid by the station. This is something which could be taken to court if the station does not pay.
