I was weary paying 20 bucks for a gas additive, but the parts store recommended it. I have a 1998 Buick LeSabre with 60,000 miles. I could truly notice a difference, in starting, motor was even quitter, and it was already quite. I didn't notice any gas mileage improvement. I recommend this to anyone who drives an older car. It did something I didn't expect to my 1998 Buick 60,000 LeSabre, and it really didn't need any noticeable help to begin with. I followed directions on back of bottle.

I have a 2002 Toyota Avalon XLS with 224,000 miles on it. The engine has been running a bit rough and there's hesitation when I step on the gas pedal. I've tried lots of fuel additives and fuel injector cleaners over the years and none have made any measurable difference until I used the Redline Complete Fuel Injector a couple of days ago. The result was immediate. The engine roughness and rumble was totally gone. At idle the engine is now whisper quiet, I had to check a couple of times to make sure it's running. And there's absolutely no hesitation when I tap the gas pedal. Instant response! And when I got on a Freeway ramp today the acceleration was remarkable. In my 15 years using Amazon I don't think I left more than one review. This product earned it for my car today!

Any Red Line product is premium quality and definitely worth the money.

Was using regular instead of premium on my 2006 Passat and I can tell in just one month it helps on the way the engine runs.
