Most experts recommend fuel polishing every 12-36 months, depending on storage conditions and fuel usage. However, if your generators see infrequent use, we typically suggest polishing every 2-3 years as preventive maintenance. Additionally, facilities in humid environments or near water may need more frequent service.
Yes! One of the advantages of our fuel polishing service is that your generators can remain operational throughout the process. Therefore, you don't need to schedule downtime or worry about losing backup power capability during the service.
The duration depends on tank size and contamination level. Typically, polishing a 500-1,000 gallon tank takes 4-8 hours. Meanwhile, larger commercial tanks may require a full day or more. Our technicians will provide accurate time estimates during the initial assessment.
Absolutely! Fuel polishing typically costs a fraction of what you'd pay to dispose of contaminated fuel and purchase new diesel. Furthermore, you avoid the environmental disposal fees and the hassle of coordinating fuel delivery and removal.
We serve the entire state of Michigan from our four locations. Our service area includes all counties in both the Lower Peninsula and Upper Peninsula. Moreover, our mobile fuel polishing units can reach any location where your generators are installed.

In many cases, yes. If contaminated fuel has caused starting issues, rough operation, or filter clogging, polishing can restore the fuel to usable condition. However, if the contamination has already damaged fuel system components, those parts may need repair or replacement in addition to fuel polishing.
