Fuel Polishing Frequently Asked Questions

Absolutely. Fuel polishing helps remove water, sludge, rust, and microbial contamination, ensuring clean, efficient fuel that extends engine life, reduces costly breakdowns, and improves overall performance. It’s a proactive service that prevents expensive repairs and downtime.

Fuel polishing is necessary when fuel has been sitting for an extended period, shows signs of contamination (such as water, sludge, or microbial growth), or when engines experience performance issues like rough running, clogging, or smoke. It’s also crucial before long voyages or storm seasons to ensure reliability.

The frequency of fuel polishing depends on usage and storage conditions. For boats, RVs, and backup generators that store fuel for months or years, an annual fuel polishing service is recommended. High-use commercial operations may need polishing more frequently to maintain fuel quality.

Yes, fuel polishing effectively removes water from fuel tanks by separating and filtering out moisture and condensation, preventing microbial growth (diesel bugs) and engine damage caused by water contamination.

Signs of bad fuel include engine sputtering, difficulty starting, excessive smoke, clogged fuel filters, reduced power, or the presence of sludge and water in the fuel tank.

Yes! By improving fuel quality, fuel polishing helps prevent engine damage, reduces maintenance costs, and extends the lifespan of fuel filters and injectors. It also prevents costly downtime caused by unexpected engine failure.

Yes, fuel additives can help slow contamination, but they don’t remove existing water, sludge, or microbial buildup. Mobile fuel polishing is a thorough mechanical filtration process that physically removes contaminants, ensuring clean fuel and optimal engine performance.

The time required depends on the size and condition of the fuel tank. Smaller tanks may take a couple of hours, while larger tanks with heavy contamination may require a longer process to achieve optimal results.

Yes! Our mobile fuel polishing service comes to you, whether your boat is at a marina, your generator is at a commercial facility, or your construction equipment is on a job site. We perform the service on location for maximum convenience.

Yes, by removing harmful contaminants that can clog filters, damage injectors, and cause engine malfunctions, fuel polishing significantly reduces the risk of engine failure and ensures reliable performance when you need it most.
