Review: How I used the product: I poured entire contents of bottle into a 2012 Toyota Camry Hybrid XLE. The car had roughly 12-13 gallons of gas when I used it. I drove mostly normally, but used engine braking to increase rpm downhill or whenever possible. It took roughly 1.5 weeks for the fuel containing 505 CRF to be used. Why I purchased the product: I mainly purchased the product as a way to fix what I felt like was throttle lag. The acceleration felt weak. Fuel economy was also a consideration on the value of this product to me. My concerns: I was skeptical of this product working due to my car being hybrid. Within the past 2 years I have also changed my Hybrid battery and noticed better fuel economy with that, but performance was still lacking in my opinion. What I experienced with CRF 505: At first, I didn't notice any changes. Not for several days driving. The car still felt "squishy" as it had been. Then somewhere between 1/2 and 1/4 it starting feeling much more responsive. The acceleration is smooth, fast, and stronger than ever. The car went from being a bit of a chore to drive to becoming fun. It feels much safer to have the car be responsive to my controls. Gas economy(full transparency): I am sure many people that get product's first concern is if this will generate enough value from the save fuel economy. I don't have enough data currently to be conclusive due to several factors such as: I haven't had fuel filter cleaned, I haven't driven a full tank of since using the product, I rely on the mpg avg display which can be off several percentage(even -/+ 5% is the difference between ~4mpg in a Camry), and driving style(due to difference in acceleration driving is slightly more "aggressive". My opinion(Should you use it): I am more than happy with my purchase. The product did what I wanted it to do. The performance improvement alone is enough Value for the Money for me, and any fuel economy is just a bonus. I believe that if I had used it on 5-7 gallons of gas it would have probably helped the fuel economy more than me using it on >12 gallons. The only reason I would have to not buy the product again: It worked correctly the first time! Follow up plan: My follow up plan is to follow this up with occasional fuel treatment using Marvel's Mystery oil, and to pay attention to my mpg to see if any changes.
Review: Great product. My big Lincoln went from a normal 22mpg to 25mpg just from having 505 CRF clean the fuel injectors in one tank of driving. Highly recommend. No, it isn't cheap, but you'll more than make the cost back in better performance and better mpg.
