Really? I always heard it was the other way around its worse for diesel in a gas due to the way gas works compared to diesel and at what temperatures they operate. I remember always being told you can figuratively put anything in the damn diesel and it would operate fine.

I always remembered back in the days with the older diesels especially here in Sweden during those harsh winters we were always instructed to put in some gasoline in the diesel engine do make it ignite easier. But this was a very long time ago.

My wife's aunt did the same thing around two years ago they fueled up diesel in their gas car and the mechanic said good that they didn't do it the other way around because that would be worse, but luckily they realised what they did before starting the car and driving of so it was easily fixed, noting got in to the engine.

Glad her car turned out to be fine! I don't think either way is going to destroy anything but I know for a fact diesel is just crude and thick and doesn't combust well in a gas engine but it's almost like highly processed oil. It lubricates well and is pretty harmless aside from just being gross and caking everything up.

OP, my 2c:
- $1,800 sounds steep - perhaps DIY or local INDY shop?
- gas engine will be just fine after flush
- I would check spark plugs condition before replacement.

Diesel HPFP is lubricated by the fuel itself. gasoline kills it nearly instantly.
IMO, there is really nothing you can damage in gas engine with modern diesel fuel.

Diesel gels at low temps. relatively small percentage of kerosine (not gasoline) helps diesel stay fluid at cold temps.

Today, in NA fuel stations switch between "winter" and "summer" diesel blend without consumer need to worry about it.
In California, most stations are now selling RND (instead of petroleum-based diesel) its native cloud point is -40C

Have gotten a tank of diesel in a gas powered vehicles before. Ex filled up car as normal and she's a motorgal. Turned out Truck driver filled premium tank with diesel and 35 people got diesel that day before they shut off the tank.

Diesel in a gas car not bad but great, Gas in Diesel car VERY VERY Bad.

diesel won't burn (or only partially burn) in a gasoline engine. The unburnt diesel will slowly work itself past the piston rings, raising the oil level, and that can eventually destroy the engine if the oil level gets so high that the crankshaft hits the oil level.

Whether or not that will happen within 1 tank in a mix ratio that the engine keeps running....probably not. But if the partner always tops up the tank with diesel so that a combustable mix is always used...over time...

I always wondered what would happen in this scenario. $1.8K is better than a new engine.

Yeah, it's curious since gasoline cans are required by the regs to be red and diesel fuel cans are required to be yellow (kerosene are blue). You'd think at the minimum to dispensary nozzles would be color matched.
