FAQ Answers for Diesel Engines | |
If closing the crankcase is such a good idea, why didn’t the engine manufacturers do it when they built the engines? All 2007 and later engines are required to have a closed or controlled device on the crankcase. Engines built prior to 2007, crankcase vents were not required to be closed or controlled. The EPA and manufacturers were not aware of the open crankcase causing extensive environmental damage and road safety issues. After tests proved closing the crankcase provided numerous benefits to the engine and lower cost to the owners, several major engine manufacturers now recommend a crankcase control system as an aftermarket retrofit on pre 2007 engines. Cummins now manufactures a crankcase control system for theirs virtually all other diesel engines. OEM providers and aftermarket manufacturers, such as Racor and Donaldson, recognized the recommendation of the OEMs and the benefits provided by installing a crankcase control system and produced a crankcase system. | |
How is the FASTechnology™ different from other manufactured systems? All crankcase control systems, including FASTechnology™, provide extremely valuable benefits for protecting the environment and making our roads safer. Systems are offered in the $600--$950 price range. In addition to being competitively priced, FASTechnology™ offers additional benefits that are not offered by other crankcase control systems. First and foremost, FASTechnology™ is the only crankcase system with a unique and patented separation technology. Other systems have a filtering technology. FASTechnology™ is the only crankcase system to reduce fuel consumption, pay for itself and require no maintenance or replacement costs. Also by not returning the contaminated oil to the crankcase, FASTechnology™ provides a cleaner interior engine environment and better oil quality, resulting in better engine operating efficiency.

What are the major advantages of installing the FASTechnology™ on my diesel engine(s)?
| |
How does the Fuel & Air Saver™ increase fuel economy? FASTechnology™ captures unburned and partially burned fuel that is currently being thrown away as it blows past the rings during an incomplete combustion. Fuel economy is increased through the process of introducing the mixture of unburned and partially burned light hydrocarbons (fuel vapors) into the normal fuel and air mixture entering the combustion chamber. In addition to burning fuel that would normally be thrown away, the burnability of the normal fuel and air mixture is increased as the unburned and partially burned light hydrocarbons (fuel vapors) are added to the normal fuel and air mixture, which results in a better combustion and greater engine efficiency.

With the Fuel & Air Saver™ installed, will I have back pressure and could it cause engine or turbo problems? No! FASTechnology™ patented separation system does not produce back pressure. The fact that FAST™ does not create any back pressure was validated through pressure gauge testing during the TMC/SAE Fuel Economy testing conducted at the Auburn University and was additionally found not to be a problem during the EPA/ETV testing conducted at Southwest Research Institute. Testing reports from SwRI and The West Virginia University Center for Alternative Fuels, Engines, and Emissions stated, “No adverse effects on engine were noted”. Top of Page | |
Will the Fuel & Air Saver™ increase the level of opacity because of “junk” from the blow-by tube? No! EPA sponsored testing validated the ability of FASTechnology™ patented system for closing the crankcase. Fuel which either has been wasted or lost by exiting out the blow-by tube is now re-routed back to the intake and allowed to mix with fresh incoming fuel/air mixture. This re-captured fuel is at a higher volatile state and increases the burn ability of the incoming fuel, causing a more complete combustion and reducing opacity; all heavy hydrocarbons accumulate by the collection canisters remain in the collection canisters. And, where filters allow soot to return back into the engine's crankcase and firing chambers, FASTechnology™ totally separates the soot and eliminates soot loading from occurring in your engine's lubrication system.

How often do I have to service the Fuel & Air Saver™? The patented see through collection canister allows the operator to easily view its contents. Although tests have shown the average mileage before service is between 8 to 10 thousand miles. Normal oil cycle change would be a safe way to track the service. Additionally, we recommend visually examining the canisters weekly to monitor the amount of oil present. Canisters should be emptied when they become 50% full. Top of Page | |
In servicing the Fuel & Air Saver™, is there a special procedure or solvent needed to clean the separator or collection canister? No! Any solvent or diesel fuel can be used to rinse the separator. Just rinse and re-install the separator onto the head, do not blow out with air. Be careful not to over tighten; hand "snug" is plenty tight. Remember, the unit is under vacuum, not pressure, and its patented seal allows for a hand "snug" install. The separator should be cleaned every 75,000 miles or once a year, whichever comes first.

What do I do with the oil collected in the collection canister? This is nothing but used engine lubricating oil and soot, and should be re-cycled with your used engine oil. Never dump the contents of the collection canister out on the ground. Treat the content as you would old engine oil... re-cycle it. The re-cycling of Used Oil is extremely beneficial to our environment and economy as it only takes one gallon of used oil to produce 2.5 quarts of new high quality lubricating oil, but takes 22 gallons of crude oil to produce the same 2.5 quarts of new high quality lubricating oil.

Will the Fuel & Air Saver™ damage my engine’s turbo after cooler, or inlet air ducting system? No! FASTechnology™ patented separation system collects the heavy hydrocarbons in the collection canister and only the usable fuel vapors are allowed to pass back into the intake. On high mileage diesel engines, the blow-by is more evident, diesel fuel has a residue which may cause some form of deposits in the collection lines, but this symptom is just that - fuel residue, not oil.

Will the Air & Fuel Saver™ void my warranty? No! Engine manufacturers such as Cummins and Caterpillar recognize the need for a closed crank case system and produce after-market crankcase control systems, which they promote as being recommended for all types of engines. As a matter of law, the manufacturer would have to prove that the FASTechnology™ directly caused the malfunction. Our EPA/ETV, TMC, and SAE tests have shown the patented FASTechnology™ system does not cause any malfunctions of any engine function and has no adverse effects on the engine. As a prudent business practice, we back FASTechnology™ with a comprehensive product liability insurance policy of $1 million dollars per claim. Top of Page | |
How long will the Fuel & Air Saver™ last? In most cases, unless abused, the Fuel & Air Saver™ will outlast the engine. In any event the materials and workmanship (excluding hoses and clamps) are warranted for as long as the original purchaser owns the FASTechnology™ system. Top of Page | |
What type of warranty does the Fuel & Air Saver™ offer? The Fuel & Air Saver™ carries a limited lifetime warranty (hoses & clamps excluded). If not abused, the unit will be replaced at no cost (excluding shipping and handling). The FASTechnology™ has been around for over 25 (twenty-five) years with most units still in service today. A one time Investment makes FASTechnology™ the best after market device on the market today. Top of Page | |
Will the Fuel & Air Saver™ cause my engine oil to be contaminated because of re-routing the blow-by tube “junk” back into the engine. No! Unlike filter devices, FASTechnology™ patented collection system completely separates and traps all the unusable hydrocarbon by-products and contaminates including soot, in its collection canister. Nothing but clean, separated fuel vapors enter into your engine's firing chamber. In most cases, tests have shown the installation of the Fuel & Air Saver™ actually reduces oil consumption and reduces oil contamination, specifically soot loading. The FASTechnology™ also becomes an early warning device by way of its “see through” collection canister. Off white or brownish looking residue are tell-tale signs of a blown head gasket or seal that would have normally gone undetected in an open ventilation system. The Fuel & Air Saver's™ collection canister actually provides an early detection system, easily avoiding the expense of a major break down. Top of Page | |
Are there any types of engines which the Fuel & Air Saver™ cannot be installed? The FASTechnology™ can be installed on all types of diesel engines. However, as a result of the extreme volume of back pressure created by some dual turbo engines, as a serious caution, until our new “large volume secondary collection canister” is available we recommend, FASTechnology™ not be installed on dual turbo engines. We anticipate that the new secondary system will be available in the very near future. Top of Page | |
