So, if you wish to prevent your **used engine with a warranty** from early failure, check out the following ways of maintaining the fuel quality/system. **Use the right type of fuel** The number one way of maintaining a fuel system is to only feed it the right type of fuel instead of the wrong or cheaper variant. So, you must treat your fuel system right by only putting the right fuel in the tank. You can easily find high-quality unleaded fuel for your used engine at the most reputable filling stations. However, make sure that you don’t put gas in a diesel-operated engine and vice versa as it can lead to engine failure. **Use premium fuel only [if necessary](https://www.mindstick.com/forum/23229/in-python-check-if-a-directory-exists-and-create-it-if-necessary)** If you have access to high-quality fuel and your vehicle does not have any specific [requirement](https://yourviews.mindstick.com/view/85169/becoming-an-influencer-requirement-of-skills-and-knowledge), then you don't need to add special or premium fuel to your vehicle.

Though new modern engines are made to tackle carbon deposits inside the engine. But even the best-used engine may fall behind on that part if it’s an old unit.
