What our customers are saying

We count on Dion & Sons mobile fueling service to keep our scrapers, excavators, bulldozers, and tractors, on all our job sites, running efficiently. No fuel shortage, no spills, no unnecessary burden, no problems.- LB 3 Enterprises – Tim Cramer
Dion & Sons was an integral part of the planning and execution of fueling to over 200 pieces of equipment during our 2016 Carson and Wilmington Turnarounds. Dion and Sons managed the fuel delivery accurately and safely 24/7 for over 45 days. Their drivers were key in keeping all the equipment running, without one piece of equipment running out of fuel over the two sites.- Phillips 66 Refinery – Carson and Wilmington, CA - N. Scatena
We were in a real bind with less than 60 days to have our facility and 40 service trucks in operation serving the Ports of LA and LB. Dion and Sons really came through for us by supplying the bulk fuel tanks, as well as the permitting and cardlock fuel services.- TTX Rail – Ricky Peoples / Quincy Chumley
