Wanted to share a testimonial we just got from a customer. This is why we do what we do!
Dear Opti-Lube,
August 2014 I bought a "low-mileage" (71600 miles) 2005 MK 4 Volkswagen Jetta TDI. Since the dealer I bought it from got it at an auction the evening before the day I bought it, he didn't have the chance to change any fluids. I went to auto parts store from leaving there and bought all top of the line fluids/filters and changed them. I started running the "gray" bottle of fuel additive at first full tank of fuel. I have the "my-cars" app on my phone and started tracking fuel mileage. I was getting 45.83 mpg average and knew it could get better. I started searching for mods and the such and stumbled upon the test results of XPD. I bought it. I also bought the oil additive. Since my oil was still good I only ran the XPD fuel treatment and my AMPG went to 49.21. After the next oil and filter change (also changed fuel filter) and adding the oil additive, I went to 52.05 AMPG my last tank of fuel. Driving a car that gets well over 750 miles on a tank of fuel is great. I drive 176 miles a day for work and don't drive any interstate. There are 27-31 traffic signals (dependent on whether going to work or coming home) on my commute one way. I felt the need to tell you that so you know my driving conditions and can see the great results of your products. I might also add that I put the oil additive in my JD riding mower and my motor runs much smoother and I get roughly 15-20 percent more running time. Thanks a lot Opti-Lube! Your products pay for themselves.
Sincerely,
Sherman S.
