2004 Envoy V-8

I purchased your Microlon Engine Treatment for my SUV. I have a 2004 Envoy V-8 with a 3.73 rear axle, purchased new earlier this year. I am an industrial salesman on the road 40 thousand miles a year. My hope was that Microlon would produce better gas mileage as you suggested and all I can say is Thank You. We started with the engine only treatment and the knowledge that the best mpg to date was 16.5. Attached are my purchases over the last 7000 miles.

I have purchased the Transmission Treatment and will report the results after the recommended 100 miles. I will probably wait 4 or 5 tanks to make sure it is consistent. It looks like I am receiving a 10% savings in mileage so far. It converts like this: 40,000 miles used yearly 4,000 = 10% savings. At an average of 18.1 mpg = 4000 Divided by 18.1 = 221 gallons of gas saved. At $2.00 per gallon that saves me $442.00 per year.
 
I also understand that my driving habits and the load I am caring in the vehicle will also affect mileage.
 
Thank you again.
 
I look forward to adding to these numbers after installing the transmission fluid.
