Injector cleaners will help you extract the maximum fuel efficiency and the best performance possible

I’ve always believed in the saying, “If you keep your car healthy, your car will keep you healthy”. This means if you take good care of your car, it won’t give up on you or leave you stranded in the middle of nowhere. It doesn’t mean just replacing tires when they go bald or keeping it good on the outside; it boils down to every teeny bit of maintenance.

One thing, however, that’s not looked into carefully is the health of the fuel injectors. They are generally susceptible to carbon deposits and sludge formation. So, cleaning them is imperative to make sure your vehicle remains fuel-efficient and there’s no stalling or idling issues. Here is a list of the best fuel injectors that you can buy for your car.

Frequently Asked Questions

What is the best fuel injector cleaner?

This question boils down to your personal preference and brand loyalty, but the best-selling injector cleaner of the lot is the Chevron Techron Concentrate Plus. It cleans the entire fuel system, including the intake valves, carburetors, and combustion chambers, and helps you get rid of the loud idling and spark plug issues.

What’s the difference between fuel injector cleaner and fuel system cleaner?

A fuel injector cleaner is useful if you are already suffering from a problem; say, if your vehicle is smoking heavily, or there is a loss of acceleration, etc. A fuel system cleaner is to be used if you’re not suffering from any major problems. It will stop carbon deposit formation in the future and clear out any mild build up.

To put it simply, a fuel injector cleaner is the medicine and is to be consumed after you’ve got the illness or are showing symptoms. A fuel system cleaner is a multivitamin supplement that is more of a precaution to protect you from falling sick.

How often to use fuel injector cleaner?

The general notion is to not use fuel injector cleaners unless you encounter issues, but it is safe to use it routinely. You can use it after 30,000 miles or so, although some say you can use it every year, too.
