See what fleet logistics leads, heavy construction companies, independent owner-operators, and luxury car owners say about J&B Diesel's premium repair quality.
"J&B Diesel manages the PM and emergency maintenance for our fleet of 24 flatbed rigs AND our pool of support vans and staff cars. Since partnering with them, our average vehicle downtime has dropped by 35%. Their diagnostic accuracy on all domestic and foreign vehicles has saved our company massive overhead."
Fleet Logistics Manager, South Florida Freight Express
"When my big rig Cummins had high coolant temperatures, and my personal foreign sedan had check engine sensors flickering, J&B Diesel handled both in their service bay. Honest pricing, highly skilled technicians who know both heavy trucks and modern foreign car computer systems inside out."
Owner-Operator, Thorne Logistics LLC
"We had two major excavators down, plus several Ford F-250 domestic service trucks with transmission fails. J&B sent out their mobile diagnostic truck immediately. They diagnosed hydraulic valve blocks and got both machines digging, and towed our trucks into their bay for immediate next-day shifter repair. Ultimate lifesavers!"
Operations Director, Apex Infrastructure Group
"Very rare to find mechanics who build commercial diesel engines but still treat standard family passenger cars (like my foreign SUV) with standard care and highly honest pricing. Their computer diagnosis pinpointed a wiring fault that two other domestic dealers wanted $2,000 to replace. Fixed it same day for a fraction of the cost!"
Passenger Vehicle Owner, Broward Education Center
