To Whom It May Concern:
About four months ago a salesman for Primrose Oil Co. of Dallas, Texas contacted us about demonstrating oil and lubrication products. This demo took about forty-five minutes and was definitely worth the time.
We purchased 510 Gear Lube; 400 Protect-o-lube, 405 diesel fuel additive, 409 diesel fuel additive, and 206 motor oil from Primrose. We have 13 service trucks that accrue 600 to 800 miles a week. Our drivers immediately noticed a drastic improvement in the performance and fuel mileage in all the vehicles.
We have saved between $400 to $550 on our monthly fuel bill and extended the time between oil changes by 50%. We noticed the biggest difference in our oldest vehicles. These vehicles were the ones that showed the biggest improvement in fuel mileage, and oil consumption. The 405 octane improver vastly improved the power in our three diesel service trucks and the 409helped these trucks start much easier on cold mornings. These three vehicles run much quieter and hardly emit any smoke.
We are very satisfied with these products and recommend them to anyone who wants to improve the performance and longevity of their vehicles.
Sincerely,
Darren Warner
