What was the first car to NOT have a manual transmission as an option?

It depends on how much diesel vs. gas is in the tank. Mostly gas on an older diesel (like my 91 Benz)? No big deal... the car would just stop running. But if it was closer to 50/50 the engine might still run... and you'd likely burn through the prechambers or pistons. If you had just a little gas it wouldn't hurt anything - in fact in the 70s MB suggested mixing some gas into the fuel tank to help prevent fuel gelling at very cold temps. The inline fuel pump is lubricated with engine oil and is rather robust.

On a newer diesel, like our prior '12 Passat TDI, the fuel is what lubricates the 28,000 PSI high pressure pump. Adding a little gas destroys the lubricity of the fuel, and the pump will self destruct and fill the whole fuel system with metal shavings

I'm surprised to hear that his employer purchased and issued a diesel car for him. I had understood that diesel vehicles had some kind of a tax or other issue, that made them a little less desirable in GRT Britain.
It looks like the repairs are on his dime.

Just an update.... Wayne now has a Jaguar as his company car, (I'm not jealous at all, no I'm not, but you know different) it's petrol (gas) so he shouldn't mis-fuel it. The Lexus survived but was given to someone else in his company & Wayne had an old'ish (17 reg) petrol Toyota Avensis, I presume as punishment for the diesel/petrol fiasco...

My Hyundai i10 will be 3 years old in March & will need an MOT test, (a roadworthy test) I'm hoping it passes OK...

Even if he does manage to put diesel in it, it won't do much harm. It won't work and some poor SOB will have to get all the diesel out, but it'd be ok afterwards. In the states diesel pump nozzles are much bigger than gas/petrol nozzles, and you physically can't put one in a gas car's filler. Is it the same across the pond? There's a sort of irony to that, isn't there? You can put gas in a diesel car and it might blow the engine, but you can't put diesel in a gas car - wherein wouldn't do much harm. Hmm.

GL with the MOT test. A 3 year old car shouldn't have any issues... right?

Yes the diesel pumps do have a bigger nozzle so shouldn't mis-fuel..... Yes it should pass it's MOT. They've made the test tougher just lately. When I took my other 7 years old car for it's MOT it passed but I got several advisories: for a 'tyre near tread limit, front brake discs nearly worn out & will need replacing before next MOT & back wiper blade split.'

There are still quite a lot of new diesels being sold over here, especially for those who travel long distances like Wayne does as he travels all over the country... Cops are always putting gasoline in their diesel cars & vans, it's a big joke in the media as there are always cop cars & vans off the road awaiting repairs after wrong fuel fill ups..

Bright Boy here had a 1976 Oldsmobile Cutlass Supreme Brougham, w/a 350 V-8. It was the most popular car in America 1975-77, they must have sold 3 gazillion of 'em. Anyhow, 1975-79 were my College years, I live in Tennessee, but went to school in Richmond, Virginia, roughly 400 miles away. Was tootlin' back to school after Spring Break, '77, needed some gas & a "Hit the Head" break, so I pulled off I-81 in Roanoke, Virginia, stuck the nozzle in the tank,went & did my business, came back to pay the gas station guy, he sez, you owe me $15... I sez, No, I used that Cheap Gas... He sez, "Well, son, you just put 7 gallons of #2 Diesel in yer car. Gulp. Now, there are times when even the meanest baddest dude alive wants his Mama, & THIS was one of them times for Moi. Will it hurt my car ? I squeaked .. Well, Shit-Fer-Brains, it won't hurt it, but it'll beat & bang, smoke, run rough, but it shouldn't hurt it...Well, here I go, on to Richmond. I went 70, prayed there weren't any cops-Virginia took "55 MPH" VERY Seriously, 'specially for out of state "Furriners"...I had the A/C on "Deep Freeze" had the radio as loud as I could stand, ANYTHING to run that Weasel juice outta my car. And yeah, it beat, banged, run rough, smoked like a freight train, the whole 9 yards. I'd stop every 25 miles or so & would top off w/"High Test' gas, as we had disconnected all the fed BS anti-pollution junk, I could run any gas I wanted. I finally got back to school, I shut 'er off, it just set there, kept running, & shook like a Baptist preacher at a Tent Revival. Well, I guess you'll eventually quit, I said to myself. Richmond was a small school, they claimed 5K students, but that was with all the law school, grad students, etc. At the part I was in there were about 1500 guys-Richmond College- and 1000gals-Westhampton College. Most good gossip took a day or so to make the rounds, I think my ordeal took about 15 minutes. People I didn't even know were coming up to me, pointing & laughing-YOU'RE the Arsewhole who put Diesel in his Gas car, aren't you ?!? What an Eediot ! Ahahahahaha...!! I paid dearly. And my dear, loving, trustworthy Fraternity brothers-Shit, they rode me worse of all... Long term, both me & my Oldsmobubble survived. You CAN put diesel in a gas car, & it WILL run, but I really CAN'T recommend doing it. Going the OTHER way around-Gas in a diesel-I don't think THAT would work at all.

[Sandy G]

I have been telling that story for nigh on for 50 years-Gulp- now, & have gotten LOTS of laughs & grins over the years... So, even if I might have suffered a bit from it, the enjoyment it has brought others-And ME- has been way more than worth what ever trouble I suffered...

I've read that some owners of low compression leadded gas cars will intentionally add ~1 gallon of diesel to a full tank of gas to try to keep the unleaded from damaging the valves...Twas on the interwebs so it might a been skuttlebutt.

My father-in-law has a Dodge Ram Cummins; about 5 years ago my mother-in-law called me out of the blue, frantic. Seems she'd pumped quite a bit of gas in the tank before she realized what she was doing. She enlisted my help. The truck would run but was very down on power; I nursed it into a local truck shop and in a day or so it was good as new. In that case I don't think they had to do anything more than drain the tank and change the filter.

I have seen, through my job, several later model diesel cars (and some gasoline models) that had the old switcheroo and didn't fare as well. Most recently was a BMW that ended up with a repair bill over $10k. No, it didn't need an engine, just a whole lot of other stuff!

I thought a little diesel wouldn't hurt a gas car. When my step dad got his Peugeot 505 (gas) he accidentally put diesel in it (his previous car was an 80-something Volkswagen Quantum/Passat Diesel) We just pumped most of it out and put gas in, no problem. That car also has a low compression engine, so I don't know if that is a factor.

A little diesel won't hurt a gas car, it'd just make it smokey. I suppose if you ran it too much, the soot might foul the catalytic. It's the other way around you have to worry about. Gas in a diesel engine can detonate rather violently. Detonation is when the fuel charge instantly explodes in the combustion chamber, as opposed to just burning from top to bottom, which is what you want. Detonation (or "knock") is never a good thing in any internal combustion engine, but diesel engines have a very high compression, so gas detonates with much more force.

If the amount of gas mixed into the diesel isn't that much, it doesn't do much damage usually. Draining the fuel tank is usually all it takes.

The only time I've dealt with this was with a BRAND spanking new 2018 Sprinter van. Hadn't even got its first oil change, and the guy driving it filled the tank to the brim with E85. It did still run, but wouldn't take any throttle. I believe the computer knew something was wrong and refused to do anything but idle. I also think it was fortunate that it was E85 instead of gas, as ethanol doesn't like to detonate nearly as much as gas does.

That's what I figured with diesel being less volatile

A little diesel in the gas isn't much different from an engine with worn rings that let a little oil into the combustion chamber.... except once all the diesel is out of the gas the engine goes back to normal which don't happen with bad rings...
