You're correct, regular or continuous use of something like diesel will damage the cat, but I don't think 2.9 gallons of it in a 15 gallon tank, one time, will do anything. It'll be up to the OP what to do.You could plug the catalytic convertor if you try to burn out the diesel. Best bet is not to crank it too much and use fuel pump powered by jumpers to pump it out. Add gas and pump it out again. If you have a fuel filter change it, I am new to Rav4. Convertors don't like unburned fuel.
My concern is that the car won't start and all that raw fuel is going into the cat. I had a car that would not start and when it finally did it had a major back fire in the exhaust and cat needed replaced. I have driven a Ford Taurus and they are known to ruin cats if you get steady misfires.You're correct, regular or continuous use of something like diesel will damage the cat, but I don't think 2.9 gallons of it in a 15 gallon tank, one time, will do anything.

All that fuel that is not burning is ending up in your convertor and your exhaust system. When your engine eventually lights off your exhaust system may explode. I had it happen to a car just be careful it can cost you thousands of dollars instead of $500. And ruin your starter!I ended up puting some 91 oct on the tank the engine will turn over until the battery dies but will not start.
In the US we have two size diesel nozzles. One is auto-Diesel size and fits cars and pickups, and would fit in any gas car.I checked the diesel nozzle size today when I got gas. The female attendant wondered why I wandered over the diesel pump after I got my gas at another pump. I asked her if the nozzle sizes were the same and she said yes, even though I think the diesel nozzle is slightly bigger, but it would definitely still fit in our vehicles. Why wouldn't they oversize the nozzles like what our US friends have?
In my travels with my dyno business I've found the larger truck/travel stations such as T/A, Love's, Pilot etc. have separate auto and big rig areas with the auto area having the small nozzles for both gas and diesel. Typically they'll only have a few Diesel pumps and mostly gasoline ones. They are in front of their restaurant/convenience stores.Doc, I would have thought nozzle sizes were a national standard, but perhaps not. In the two stations I use in NY, there are only two sizes, small for gas vehicles and large for any diesel vehicle. I know two people with diesel VWs and they both have a large opening in the fill pipe. All other gas fueled vehicles I've ever seen have a restrictor in the fill pipe which will not allow the diesel nozzle to fit. Perhaps this is a state thing? I'll do a little googling when I get time, this is interesting to me.
He just meant "high test fuel" , which for us, is 91 octane. This isn't the first time I've heard of someone accidentally trying to fill with diesel. Most times the gas attendant can spot the problem and shut off the pump before they get too much in their tank.Don't know what you mean by "some 91 oct". You would need to fill the tank in order to dilute the 3 gal of diesel as much as possible.
According to kevcules46, Canada apparently doesn't have regulations for fuel nozzle sizes.
My question actually was how much "some" was. It could have been 2 gallons from a lawn mower can when he needed a full tank of gas to dilute the diesel. At any rate, his car seems to be fine now.He just meant "high test fuel" , which for us, is 91 octane. This isn't the first time I've heard of someone accidentally trying to fill with diesel.
