LISTEN 10:16

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.

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.
