Diesel Fuel Polishing & Conditioning
Keep your diesel generator's fuel supply clean, dry, and ready for emergency operation
Why Diesel Fuel Degrades
Diesel fuel stored in standby generator tanks begins degrading within 6-12 months. Water condensation from temperature cycling, microbial growth (diesel bug), oxidation, and particulate contamination can turn clean fuel into a reliability risk. Contaminated fuel causes injector fouling, filter clogging, and engine failure—often at the worst possible time, during an extended power outage when your facility needs backup power most.
Buffalo Power Solutions provides professional fuel polishing services that filter, condition, and restore your diesel fuel supply to manufacturer specifications. Regular fuel polishing is a fraction of the cost of emergency fuel replacement and generator repair caused by contaminated fuel.
Benefits of Fuel Polishing
Extended Fuel Life
Removes water, particulates, and microbial contamination to extend the usable life of stored diesel fuel.
Reliable Starting
Clean fuel ensures your generator starts and runs reliably during emergencies—no injector fouling or filter clogging.
Reduced Maintenance
Prevents fuel-related engine damage that leads to expensive repairs, injector replacements, and unplanned downtime.
Compliance
Maintains fuel quality standards required by NFPA 110 and generator manufacturer warranty requirements.
Our Fuel Polishing Process
{ "title": "Fuel Sampling & Analysis", "description": "We take samples from the tank bottom and mid-level to test for water content, microbial contamination, particulate levels, and oxidation." }
{ "title": "Water Separation", "description": "Multi-stage filtration removes free water and emulsified water from the fuel supply using coalescing filters." }
{ "title": "Particulate Filtration", "description": "Progressive filtration down to 2 microns removes rust, dirt, and degradation byproducts that clog injectors and filters." }
{ "title": "Biocide Treatment", "description": "If microbial contamination is detected, fuel is treated with EPA-approved biocide to eliminate diesel bug and prevent regrowth." }
{ "title": "Post-Polish Verification", "description": "Final fuel samples confirm the fuel meets cleanliness standards. Results are documented for your maintenance records." }
