How often should I change the fuel injectors on my car?

Question

I have an 2003 Impala and the fuel injectors have not been replaced.

Answer 1

If you install Chevron Fuel Injector Cleaner in your gas tank twice per year you will never be required to change injectors. If you have Texaco gas stations near you the above cleaner is already mixed with their fuel. This cleaner is available at any auto parts store. NAPA, Car Quest, Advance Auto Auto Zone and Wal Mart. NAPA has another product, Sea Foam which does a good job. These two products also clean valves and combustion chambers which is a welcome plus. You will be happy with either of these products. Good Luck.

Answer 4

Fuel injectors usually last a long time (8+ years). I would only replace them if the engine is not firing smoothely. A bad fuel injector should respond the same as if the spark plug is unplugged.

I do that when I get my oil changed about every 3000 miles. I have a new car. Normally fuel injectors last about 80,000 or so miles before they need replacing and they are not cheap. This helps lubricate and keep them from getting dirty and plugged.

Answer 6

You should replace them whenever you want to waste about $900.00! List price on those are $146.66 each!

Injectors rarely fail, and also raerly plug up. They are not a routine maintenace item.

Answer 7

You should only have to replace them if they are leaking, just use a pro cleaning kit every couple of years, they hook into the fuel rail and the engine runs on it until it dies then remove can.

Answer 8

Never, unless there is a fault with them.
