Q: How often should I be testing my ULSD fuel sites for sulfur?
A: Federal code does not mandate sampling. Federal Code, however, does state that a
      Fuel Quality Assurance Plan must contain sampling at a regular frequency in order to be
      considered a QAP. The Fuel Quality Assurance Plan is the only avenue for a marketer
      (retailer, jobber, transporter, bulk storage site) to prove he/she is in compliance with the law.

Q: How long will my results take once you receive the sample?
A: We strive for a one day turnaround time but guarantee three business days after receipt.
      Rush service is available for an extra fee.

Q: How much will your services cost me?
A: Our prices are very competitive. Please call for a list of services and prices.

Q: How do you offer such fast turnaround and great service?
A: Since we are a small company we are very efficient in our day to day operations.
Great service to our customers is always our #1 goal.
