Of course, every one of us knows the right kind of fuel for our car, but when you have to rent one, how could you be sure? Putting diesel into a petrol car or vice versa would still make the vehicle up and running, but eventually, it will inflict irreversible damage to the car. Not to mention that the money to fix this type of damage is not covered by almost any rental agreement. So if you're confused about how to identify between 2 types of cars, take a look at these tips below:
Below are tips to identify between petrol-only and diesel-only cars. You could use one or all of them to be really sure:
1. Listen to distinctive sound
Old diesel cars have a very unpleasant sound when the engine is on, compared to that of their petrol counterparts. The sounds will get heavier and heavier as the vehicle gets to the road. Still, modern diesel cars are integrated with computerized systems don't produce much noise, so you probably need more than this one tip.
Old diesel cars not only make annoying sound but also release more smoke
2. Check the label on the fuel cap
The internal side of the fuel door often have labels such as "Gas only" or "Diesel only" and you should see it very easily when you stop for fuel. This can differ between models. Some print this label outside the fuel door, on the car key or on the tableau. Generally, the label will show up somewhere visible inside or outside your car.
3. Find the clue in the Model name
This one is easy and should be obvious. Diesel cars will often have the word "D" in it. For instance, the BMW 535D or Infiniti EX30D all run on diesel. The name of your vehicle will often appear on the back of the car.

4. Take a look at the engine
If you're an experienced car owner, you should know that there difference in the engines of diesel-operated and petrol cars. Some old diesel vehicles don't have the throttle body or the air flow sensor. Also, engines running on diesel don't have a spark plug.
5. Find matching fuel pump
If you can't use any of the tips above, try this one. Generally speaking, new petrol models have a rather tight nozzle compared to a thick and wide nozzle of the diesel pump. If you have to use force to put the nozzle into the fuel tube, it's probably the wrong one for your car
Unfitting nozzle could be a sign
On the other hand, since the petrol's nozzle is smaller than that of a diesel car, it could slide easily into fuel tube. So when you plug it in, make sure it's not too tight or too loose.
