I own a 2008 Hyundai Sonata 3.3 liter V-6. I drive for a Dr.’s office and over 90% of the miles are city driven. Prior to using Fuel Infusion I had noticed a decrease in fuel economy and engine performance over the last 6000 miles. Over the last 3,600 miles my engine developed a foul, rotten-egg smell which was getting progressively worse.
My engine began stalling and became hard to start at times. I considered an expensive tune-up (almost $300) which is not recommended until 100,000 miles. I suspected that my catalytic converters were beginning to plug up. A mechanic friend told me that they would eventually have to be replaced. The replacement cost of both converters would cost over four times the tune-up cost. Prior to using FI, another problem I was having on the highway, I tried coasting; putting the gear in neutral and it would stall every time. I found this out one day, by inadvertently bumping the shifter into neutral and the car stalled. Over the last 17 months I’ve used expensive engine and fuel system formulas: ZMax, cost over $40 with tax, Cheveron’s Techron Fuel System Cleaner, cost approx. . . .70 cents an ounce to treat a gallon of fuel = $14 for 20 oz which was suppose to work for up to 3,000 miles, and Lucas Upper Cylinder Lubricant w/ injector cleaners & fuel conditioners. A 32 oz container = 5 treatments. (6 oz treats 20 gal) for about $9, a cost of $1.50 per tank of treated fuel.
During my research for a solution to the problems my car was having, I came across your FI product which claims to reduce the activation point of fuel combustion from 600 down to 200 degrees. I thought, “well hell, I’ve tried everything else, why not FI?”
Fuel Infusion does everything that you claim it does! NO HYPE! AMAZING! I added the tablets, and after driving about 30 miles, I could feel an increase in engine performance. I was quite simply amazed! A few months ago I installed a K&N air filter which helped a little, but nothing like your FI. After getting home, I followed your simple instructions and rebooted my Sonata’s computer overnight. In the last 3 weeks since using FI, I’ve put over 2,600 miles on my car. After using two treated tankfuls, I noticed my exhaust tips were covered in black carbon soot. I realized FI was actively, and immediately cleaning the carbon from my engine - AMAZING! Also, that foul rotten-egg smell lessened with each treated tank of fuel. After four FI treatments ($12 cost, double treatments) that foul smell is gone! After just two treatments of FI, I noticed an increase in city MPG, from 20.9 to 21.6.
My engine now runs smooth without hesitation and without stalling. No more foul exhaust smell and no more soot on the tail pipes. All the power is back. When I touch the accelerator, it takes off like a rocket! I don’t need a tune-up now, and I don’t need to replace those costly converters, saving me at least $1200 in repair costs. Plus I’ve spent at least $300 or more annually over the past 5 or 6 years on fuel system products, because I know they keep your car running at the optimal level. Hands down FI beats them all! Fuelinfusion is the only fuel system product I’ll ever have to use again! Amazing, Amazing, Amazing, is all I have to say!
