I have a Toyota Yaris hybrid from 2018. Last saturday my tank was half-way full, but I had to buy some things at the gas station and decided to purchase 7 or 8 litters of unleaded gasoline (10 euros). That sunday I used my car for 20 km or so with no issues. On monday I went to work, and I noticed that my car was vibrating too much when the gas motor was on. On my way back home, the vibration was more noticeable and I decided to take it to the dealership repair shop.
The mechanic there said that there was an issue with the fuel: Apparently I put diesel in the car instead of gasonile. Now, I don't know how that diesel got to my car's tank because of the following reasons:
- I have a receipt from the gas station staying that I bought gasoline and not diesel. Where I live, you pay in advance for your gas and the only nozzle that activates is the one corresponding to the one you purchase.
- The diesel nozzle is bigger than the gasoline one, and does not physically fits into my car.
- I'm not that stupid.
I asked for a sample of the "mixed" fuel on the repair shop. I compared that sample with a "clean" one from the gas station, and they seem different to me (different color and smell).
In the repair shop, they replaced the sparkplugs with new ones, and emptied the fuel tank. The car now is running fine. I had to pay for the repairs, and they said that I lost my warranty on those items that may be affected by the faulty fuel.
I don't know what is happening here. If I really put diesel in my car, how could that happen? Can the gas station have a say in all this? Is it possible that the diagnosis of the mechanics was wrong?
I'd love to hear any ideas. Thanks.
