>>As the owner of a VW Jetta, 23K miles, this is music to my ears.

>But... is it Diesel? Diesel engines last a lot longer than gas engines, plus they are a lot more efficient in terms of gas mileage.
>However, there are disadvantages... Yesterday I had the misfortune to stop for fuel before work at a full service station, and the attendant put gasoline instead of diesel! Luckily he realized the mistake in time, and I did not start the engine. He attempted to siphon the fuel out, but because it is a 2005 Jetta he could not do it, so I had to tow it to a VW service, and it turned out to be a ~200 job! VW road assistance program covered the towing cost, but not the service, so I paid that and the attendant reimbursed me today. I feel sorry for him, hopefully the gas station will give him a refound. For the price of 5 hours of work missed and some stress I think my lesson is to not trust the attendants anymore.

And, surprisingly, it does work the other way 'round. Well, almost. Once during the years of the wars in which my country "didn't take part", we went to a peasant's barn to buy some gas for the company Yugo. The barrels weren't marked, and we were very tired (worked all day at the customer's, and had a three hour drive home ahead of us) so nobody noticed which barrel was greasy and which was clean... so we poured from the greasy one. Which meant diesesl - gasoline evaporates and doesn't leave stains. We tilted the Yugo about 20 degrees to the side so we syphoned out most of the diesel, and then poured the regular in. Unfortunately, we did try to start the engine on diesel, and it sucked some of it into the carburetor.

And it worked! Though, first kilometer it spewed out thick black smoke, and coughed and hiccuped a lot, until it came to slurp the clean stuff. Then it purred on.
