STP Pro Series Car Intake Valve Cleaner - 20 Oz Engine Treatment for Cars, Trucks & Motorcycles | Removes Carbon Deposits, Improves Performance & Fuel Efficiency | Ideal for Routine Maintenance & Engine Restoration

I really didn't know about the issue with fuel injected engines getting build up on the intake valves until I stumbled across it on a car forum when I was researching another problem. My car only has about 35K miles on it, but from what I was reading, you can get build up in as little as 10K miles. I was doing some other maintenance anyway, so I thought I would give this a try even though the engine was running fine. I followed the instructions on the can and it worked like a champ. The check engine light came on 2-3 times while it was spraying, but went off after a few seconds. I did a test drive around town after it was done and it seemed to run fine. The next day I went on a road trip of over 300 miles. This trip usually takes about 3/4 of a tank of gas. It only took about 5/8 of a tank. The return trip was even better using barely 1/2 tank. I'm really pleased with those results especially with gas prices the way they are. I plan to use a can of this at every other oil change because it's clearly doing something right.
