Fill-Good Stories

Having Greg’s Petroleum Service as our fuel and lubricants supplier has changed the game for us. They have gone above and beyond for our company. From helping us get our bulk fuel tank up and running, to finding us a yard to park or trucks closer to a job site, they have done so much to save our company the most when it comes to fuel. I would recommend Greg’s Petroleum Service for their helpfulness and determination to help companies succeed.

— Natalie Elizalde, General Manager, Premier Valley Transport

Our father Jim Hronis started doing business with Harold Gregory from the start of Greg’s Petroleum and since the beginning we’ve always been well taken care of. Even during the fuel shortage of the mid 70’s when everyone was searching for fuel, our tanks were always full and there was no interruption to our farming business. They are a dependable fuel and lubricants source – one of the many reasons we are loyal to Greg’s.

— Pete Hronis, Vice President Sales, Hronis Inc

With Greg’s Petroleum, we feel like we are always taken care of. They manage our inventory, are quick to respond when there is an issue, provide quality products and great service. Their recommendation for switching to Delo has helped make our company more successful. They’re a partner we can trust to make our needs a priority.
