FAQs about our liquid Fuel Borne Catalyst additive

A: Add 1 ounce of Better Diesel FBC for every 25 gallons of diesel.

A: This means that Better Diesel FBC meets or exceeds EPA criteria for demonstrating no harm to either engines or the environment and is approved for use in all US road diesel.

A: Yes.

A: Yes, Better Diesel FBC works the same way in all diesel engines with or without after-exhaust "emissions" treatment systems.  On-going use of Better Diesel FBC improves combustion efficiency on average by approximately 10%, (ranging from 6 – 14%), as measured under controlled engine test conditions. Individual results will vary depending on the engine and “real-world” driving conditions.

A: One (1) gallon of Better Diesel FBC will treat 3200 gallons of diesel fuel at a cost of around $.07/gallon of fuel. This translates to approximately $0.01/mile of cost assuming a baseline for fuel mileage of 7 MPG. 

A: Yes, Better Diesel FBC reduces and/or eliminates soot deposits throughout the engine, the DPF, and other exhaust system components. Soot is the primary culprit for DPF regeneration problems as well as premature engine wear and emissions system component failures. However, unlike soot, ash cannot be burned off. "Ash" deposits have multiple sources (fuel contamination, engine oil additives, dirt and dust) and make up a minute fraction of the exhaust emissions. Residual ash from the exhaust slowly accumulates in the DPF over time. We recommend that you adhere to the OEM recommended interval for routine cleaning of the DPF to remove ash.

A: Yes, Better Diesel FBC works extremely well to improve engine performance and lower fuel consumption and emissions for diesel pickup trucks and passenger cars. The dose is 1 ounce per 25 gallons.

A: Yes, but please change the dose to 1 ounce per 30 gallons. It works especially well for classic cars.

A: Yes, please see our distributor website with Pittsburgh Power, https://pittsburghpower.com/pages/max-mileage for locations and contact information.

A: The catalytic effect of Better Diesel FBC improves combustion directly. As a result, it acts as a cure to most problems caused by the incomplete combustion of diesel and gasoline. 

A: No, our independent tests using ASTM D6079 demonstrate that Better Diesel FBC has no measurable effect on the lubricity of diesel fuel.

A: Yes, it is safe to use Better Diesel FBC along with all other types of fuel additives. Please do not mix additives directly. Instead add each of them separately to the fuel tank.

A: Yes, 60-70% lower soot production by the engine means that engine oil stays cleaner longer.  Also, with long-term use of the catalyst you may see an increase in elemental iron. This is nothing to worry about as long as other wear metals stay consistent and low.

A: No. The iron-containing catalyst molecule which serves as the active ingredient in Better Diesel FBC is fully soluble in diesel and gasoline. There are no solid particles of any kind that could possibly cause problems with the high pressure fuel pump or fuel injectors.

A: Yes. First of all, consistent use of Better Diesel FBC will burn off the oily black soot coating on the front face of the DPF so that the natural "eggshell white" color of the DPF ceramic substrate will show through. For an in-service diesel engine this typically occurs within use of the first 1-2 gallons of Better Diesel FBC.

With longer term use it is possible that a faint reddish-orange tint to the otherwise clean DPF filter inlet-side may develop. This is caused by the catalyst active ingredient which thermally degrades to trace quantities of iron-bearing “ash” and is generally not of any concern.

A: Better Diesel FBC increases the thermal efficiency of all diesel engines which results in the lowering of the exhaust gas temperature (EGT) by a small but significant amount. Since NOx production is thermally driven it is roughly proportional to EGT. As a result, the fuel catalyst treatment has been measured to reduce NOx output by about 15% on average although individual results will vary. In newer engines, the SCR system may respond by injecting less DEF fluid into the SCR system.

A: The time it takes for Better Diesel FBC to burn off accumulated soot and carbon deposits for an in-service diesel engine is approximately 4 to 6 weeks. Keep in mind that the initial “clean out phase” may produce higher levels of smoke as the soot is being burned off at a lower temperature with the help of the fuel borne catalyst. In some cases, especially for very high mileage engines, DPF sensors may react to to this temporary condition and things may appear to get worse before they get better. This is normal and should pass without resulting in an engine “derate” situation.

Please note: more frequent fuel filter changes may be necessary during the 4-6 week "clean-out" phase, especially if any micro-bacterial contamination is present in the fuel tank and fuel lines, a.k.a., "algae".
