It’s an uncommon issue, however, a horrifying one in the meantime!
When an unwitting driver accidentally puts the diesel fuel into their gasoline-powered car, bypassing the differently sized nozzles, then it may cause a disaster for your engine.
When you put diesel in car by mistake, it implies you are putting the heavier fuel into the baseline fuel-gasoline. Gasoline is lighter, consume at lower streak temperature than diesel, and is more volatile.
Keeping these all distinctions in mind, putting the diesel into gasoline would not cause so many issues as the turnaround situation can cause!
The greatest inconvenience is the decrease in the octane.
Thinking about how gasoline works in an engine, octane rating is the measurement of a gasoline’s ability to ignite at the right time. Gasoline with low octane rating will ignite too fastly when it is injected into the chamber. Then gasoline ignites and explodes but at the same time piston is still on its way and the resulting pressure wave smash gives you a knocking sound and the worst damage to the piston and rod. Octane slows down combustion and delays it.
On average, gasoline needs to have an octane rating of 82 to 91 to fit today’s car engine at its best. While diesel octane rating is in the middle of 25 to 40. Mixing two points diesel fuel into the gasoline will bring down the overall octane rating of the engine by one point, and by adding five points can bring down the more octane rating of the engine. So, when you put diesel in car by mistake, it can easily create a problem in most engines.
The more massive amount of diesel contamination in the gasoline will harm the engine and can give you cracked heads and blown pistons. When you put diesel in the car by mistake, it will provide you with dirty combustion and can harm your car’s engine over the time if no progression is taken.
