I managed to pump 30 Litres of ULP in my  i30 Turbo Diesel one morning.

 

Can anyone guess what happened....?

my guess is it came to a fairly sudden stop a short distance down the road.

 

The hilux is still going strong, so I guess it's safe to say the newer diesel motors can handle a bit of petrol.

In the past year he was aware of four instances in Tasmania where expensive diesel cars, such as BMWs and Volvos, had their engines destroyed.

Typically the cars started and ran OK for about 1km, using up the residual diesel in the fuel system, before they began to rattle.

"Then they just stop," he said. "That's bad."


RACT is now offering motorists a $75 ($65 for members) device which can replace the fuel cap on most diesel models. It will only admit the standard sized diesel nozzles.

"It's a very cheap insurance policy," Mr Moody said.

this second article explains how much of the engine damage from the incorrect petrol fill may not show up for months

http://www.telegraph.co.uk/motoring/2737057/A-costly-mistake.html

Petrol wrecks diesel engine lubrication processes and is particularly damaging to a diesel engine's costly, high-pressure fuel pump, which operates at up to 2,050bar (30,000psi). Petrol removes the pump case hardening and if a film of hardened metal disintegrates into swarf it will greatly harm or even wreck an engine's internal organs.

At best, if the engine is not started or perhaps run only very briefly, the fuel tank and its internal pump, fuel lines, main high-pressure pump, fuel injectors and filters will all require removal, clearing and re-installation (which might include some renewal) at a cost of up to £7,000. At worst, several parts will need replacing, even the engine itself, at a potential cost of £12,000, or more for a top executive car.

just quoting a 2001 2.8 litre TF Rodeo turbo and fuel pump...made it 9 kms on petrol, lost power (boost) and then stopped

3k odd for parts... not quite 5k including labour

February 2012................. 1 in 10 caught out with wrong fuel...............

An NRMA Motoring & Services survey has revealed that one-in-10 motorists have filled a motor vehicle with incorrect fuel, with almost half of those blaming confusing signage at the bowser.

The NRMA survey of more than 1,300 motorists found (17%) of those who filled up with the incorrect fuel had put petrol in a diesel engine, which has the potential to cause considerable damage to the engine.  A further 5% had put diesel in a petrol engine which, means the vehicle will stop soon after starting, require towing and a fuel system service.

The NRMA survey also found that 10 per cent of those who filled up with the wrong fuel were left with a damage bill of up to $500, an additional 5 per cent said their bill reached as high as $1,000.

In addition, the survey showed men were more likely to have filled a vehicle with the incorrect fuel than women. The findings also showed three quarters of respondents (76%) incorrectly filled their own vehicle, followed by a company vehicle (11%) and then a family member’s vehicle (10%).

The NRMA has introduced a fuel evacuation service trial for motorists within the Sydney Metro area who have inadvertently filled their vehicle with the incorrect fuel type. The service where available will be free for Members during this trial period

DO NOT TURN THE KEY! Even if you don' start the engine turning the key will cause the pump to circulate petrol through the system. BYE BYE ENGINE!

 

The vehicle must be towed to a diesel mecanic who will drain the entire fuel sytem and flush it with diesel.

 

Petrol acts as a solvent and remove the protective lubricant film. This causes metal on metal wear in the injector pump and fuel system. The metal particles will cause severe engine and fuel sytem damage.

 

Petrol does not detonate ("explode") in a diesel engine. It simply causes severe wear due to a lack of lubrication.  [Diesel army tanks are designed to run on petrol as an emergency fuel.]

Only run your multi pistoned engine at a minimum of 95 octane rating


 


... your engine, your mechanic and your hip pocket will all thank you
