STA-BIL® Fuel Stabiliser FAQ

What causes fuel to go stale?
Petrol is a mixture of many components with different properties that contribute to the performance of the fuel. When petrol is left out in an open container, or exposed to the air through normal fuel tank ventilation, it will in time completely evaporate. As it evaporates the composition and properties change because different components evaporate at different rates. This is a normal feature of petrol and the same process takes place in equipment fuel tanks.

How does STA-BIL® protect against deterioration?
STA-BIL® is a blend of scientific additives which act together to prevent fuel from degrading and oxidising during prolonged storage. STA-BIL® acts as a protective wrapper around the fuel molecules so they cannot combine with oxygen or other contaminates to corrupt the fuel. STA-BIL® ensures that all of the components that make up the fuel evaporate at the same rate so that there is little or no alteration to the composition over time.

Can I add STA-BIL® to old fuel to revitalise it?
No, once the fuel has deteriorated due to the evaporation of key ingredients it cannot be revived effectively. STA-BIL® is a preventative product to stop this happening and save you from the problems that are associated with stale fuel.

Can I use regular STA-BIL® in my diesel powered equipment?
Regular (red label) STA-BIL® is designed for use in petrol engines only. There is a diesel specific version (green label) available exclusively for diesel engines.

What happens if I get the dosage wrong?
Under dosing will reduce the effectiveness of the treatment.
Over dosing – There are no negative physical effects from using higher than the recommended dosage of STA-BIL®.

Is it better to store my vehicle or equipment with full or empty tanks?
When storing any petrol powered machine or even fuel stored in fuel cans or drums it is always beneficial to store it full rather than empty. The most significant catalyst for fuel going stale is evaporation. Evaporation is caused by air, and the more fuel there is present in the tank or vessel the less room there is for air which will cause the fuel present to go stale sooner than it would if the tank is full. This is true whether the fuel has been treated with STA-BIL® or not.

Many people believe that simply starting and running the engine every few weeks will be sufficient to keep it in good running condition, is this true?
It is partly true ... running the engine every few weeks will lubricate oil seals and keep the battery charged but it will do nothing to prevent the fuel in the tank from going stale. This is why it is important to treat the fuel in infrequently used vehicles and equipment with STA-BIL® as it will prolong the life of the fuel significantly ensuring quick easy starts next time you want to use it.

STA-BIL® Diesel Formula FAQ

Can I use Regular Formula STA-BIL® in Diesel?
Diesel fuel systems and gasoline systems are designed differently, and require different additives. In addition, regulations issued by the EPA over the last few years have resulted in diesel fuel reformulations (to Ultra Low Sulfur Diesel fuels), creating a need for more specialised diesel specific additives. In 2010, we created a special Diesel Formula STA-BIL, designed specifically to address problems related to the new Ultra Low Sulfur Diesel fuels and new diesel engine technologies, including thermal oxidation (heating of fuel), sludge and sediment formation, corrosion, and lubricity issues. It also helps remove water from the fuel. Using Regular STA-BIL in Diesel will not harm the diesel system in anyway, but will not be effective.

Why Should I use Diesel Formula STA-BIL® Fuel Stabilizer?
In 2006, the EPA in the USA mandated the reformulation of diesel fuels, reducing sulfur content to less than 15 ppm. These new reformulated diesel fuels, called Ultra Low Sulfur Diesel and Bio-Diesel, are less stable than diesel fuels of the past. The reduction in sulfur also means less lubrication to protect the diesel engine from wear, leading to more breakdowns and major engine problems. Diesel Formula STA-BIL® is specially formulated to help prevent sludge and sediment formation and the darkening of diesel fuel. Diesel STA-BIL contains high levels of detergents and lubricity agents, and when used regularly, helps remove these sediments as well as any fuel system deposits that may have already formed, in addition to lubricating critical fuel system components to keep your diesel engine running like new.

Does Diesel Formula STA-BIL® also help remove water?
Diesel Formula STA-BIL® helps remove water from the diesel fuel, eliminating the environment in which fungi and algae require to grow in. Diesel STA-BIL® demulsifies water (breaks the water into small droplets) dropping it to the bottom of the fuel tank, where the fuel/water separator removes the water from the fuel, allowing fuel to move safely through the fuel system. By removing the water before the fuel flows through the fuel system, Diesel Formula STA-BIL® also helps protect against corrosion.

When should I use Diesel Formula STA-BIL®?
We recommend using Diesel Formula STA-BIL® at every fill up to protect your fuel system year-round from corrosion, sludge and sediment formation, and moisture. This product should also be used during storage to keep the diesel fuel fresh. For use in every tank, add 30ml for every 38 litres (126:1 ratio). For storage, use 30ml for every 21 litres (63:1 ratio)

303® Protectants and Cleaners FAQ

303® Fabric Guard warns not to use it on "synthetic suede". Why Not?
Fabric Guard imparts enduring water repellency to all natural leathers - upholstery, clothing and footwear (including deerskin and suede). 303® Fabric Guard protects against soiling & staining as well as helps the leather be water resistant. 303® Fabric Guard should not be used on synthetic suede, not because of the product itself, but because of the carrier, Odorless Mineral Spirits (OMS), a mild solvent. As a general rule, even mild solvents should not be applied to rubbers & plastics. Synthetic suede is a plastic.

How do I apply 303® High Tech Fabric Guard Correctly?
Here are some special tricks to applying 303® High Tech Fabric Guard.
Make sure the surface you are treating is clean.
Make sure the surface you are treating is dry.
Do not overspray! Saturation is not necessary. The surface needs to be slightly damp but not soaked. The polymer 303® uses in it's Fabric Guard helps the product go down deep into the fabric. There is no need to treat both sides of the surface. The top side is preferred.
Maintenance is essential. You can lightly mist the surface every 6 months to check the water repellency. Friction will wear away product more quickly leaving the fabric unprotected. If this is the case ... such areas can be spot treated to renew repellency.

How do I apply 303® HTFG in the Wind?
The quickest and easiest way to handle this is to employ a flat piece of cardboard. If you're right handed hold the cardboard in your left hand. Hold it just upwind of where you're spraying. The cardboard blocks the wind, you don't waste product and you achieve expected coverage rates.
The cardboard trick is also handy to protect surrounding areas from over-spray. For example, use the cardboard around the edge of the convertible top while retreating. This minimizes or eliminates over-spray onto glass, chrome, etc. (Immediately wipe up any over-spray from adjacent surfaces with a dry, absorbent cloth).

What is the difference between silicone 'water repellent' fabric treatment products and 'fabric protectors'?
Silicone water repellent fabric treatments are inexpensive products common in the RV & Marine industry where they are sold to "waterproof" fabric covers, bimini tops and boat enclosures.

1) While silicone water repellents have good though relatively short-lived water repellency, they have the following negative aspects: 1) Silicone treated fabrics soil more readily than untreated fabrics. 2) When soiled, silicone treated fabrics are much more difficult to clean than untreated fabrics. 3) Silicone treated fabrics have zero resistance to oil based staining agents such as skin oils, sun tan lotions, smoke and emissions from barbecues, jet engines, cars and boats. 4) Silicone water repellents cause oil based stains to bond almost indelibly to treated fabrics.

2) True fabric protectors also provide water repellency. But in contrast to silicone treatments, a true fabric protector will cause the treated fabric to resist soiling, will make the fabric easier to clean when it becomes soiled and will resist both water and oil based stains. Though even the lowest grade of fabric protector will typically out-perform any silicone water repellent, silicone products are extremely inexpensive, very common and extensively used by the uninformed.

3) Manufacturers Warranties: The use of silicone water repellents my void the manufacturer's warranty. Example: Sunbrella®, manufactured by Glen Raven Mills, is well known as the best quality fabric for most outdoor applications. Sunbrella® is used internationally in most commercial awnings, most of the world's fabric automotive convertible tops, and in a high percentage of marine covers, bimini tops and boat enclosures. Sunbrella® is extremely resistant to UV light, but after cleaning or a lengthy period of exposure may require treatment to replenish lost repellency. The use of silicone water repellents is specifically recommended AGAINST by Glen Raven Mills and can void the multi-year factory warranty. The product Glen Raven Mills recommends for treating Sunbrella® is 303® High Tech Fabric Guard, commonly available from most marine mail order catalogs and chain stores.

Does 303® Aerospace Protectant™ always 'work' on fiberglass?
Yes, 303® always works unless there is something on the surface keeping the 303® away from the fiberglass. This something can be a Teflon, silicone or polymer sealant or fresh wax. If the surface has been freshly waxed, there is no need to remove the wax. Instead, just wait a few weeks. Wax does not last long enough to warrant the effort required to remove it. Only about 2% of the time is prebuffing (compounding) necessary prior to using 303®. When compounding is required to remove the heavy layer of accumulated oxidation, be sure to use a rubbing compound that does not leave a coating or sealant. Use one containing only the finest abrasive.

Is 303® Aerospace Protectant™ effective On Latex Rubber?
Yes, 303® Aerospace Protectant™ is the most effective UV screening and anti-ozonant protection for latex rubber as latex (natural rubber) quickly degrades when exposed to UV light and ozone.

The plastic dashboard window on my car is milky and dull - is there a way to fix this?
We have had a few consumers with this same type of problem. 303® itself will not dull or make plastic milky. What has happen usually is someone used a type of window cleaner on the plastic which contained alcohols or ammonia. When these types of products are used it degrades the plastics - and if 303® Protectant is applied after, the problem becomes even more apparent. Using a fine rubbing compound remove the carefully polish out the milky look of the plastic. The last and most important step is once you successfully removed the cloudiness or milky look with the rubbing compound be sure to apply 303® Aerospace Protectant™ and polish dry.

What is the Shelf Life of 303® Aerospace Protectant™?
If 303® Aerospace Protectant™ is protected from freezing it will retain its effectiveness 5 years or longer. (It is best to store most surface treatment products at room temperature).

What's the right way to maintain the plastic windows in my soft-top or outside awnings?
The material used for the `plastic' windows in convertible tops, soft-tops, boat enclosures, etc. is a specialized type of vinyl called `Pressed Polished Sheets', or 'pressed poly'. The material is actually two layers of non-colored vinyl laminated together under intense pressure and high heat. This process squeezes out all the impurities and renders it perfectly clear.
This material is soft and easily scratched and is not made in rolls but in sheets, which are separated by paper. Also known as `sheet goods', finished stock is always gently rolled and then stored and shipping standing vertically, never laid down.
On clear vinyl plasticize loss and UV exposure cause embrittlement, yellowing and failure. Like all vinyl, clear vinyl contains plasticizers (to keep it soft and pliable) and UV stabilizers (to retard UV degradation)
Clear vinyl loses its plasticizers much more rapidly than top-coated vinyl. An UV protection added in the manufacturing process is less effective each day. Consequently, if clear vinyl windows on a vinyl soft-top are not properly cared for, they can fail within 2-3 years while the vinyl top itself will last for years longer.

When do I reapply 303® Aerospace Protectant™ to my Vinyl Spa Cover?
Use `303®'s cosmetic properties and water repellency as a guide. A surface treated with 303® Aerospace Protectant™ is water repellent (beads water). When the water repellency begins to diminish, reapply.
Or (our preferred method) if you think it may be time to reapply but don't know for sure, do a small spot with 303®. If any of the colour or lustre comes back, reapply.
Vinyl spa covers are one of the few Constant Exposure situations for vinyl. Even RV vinyl awnings, vinyl convertible and soft tops, tonneau covers and car bras are not constantly exposed all day, every day. It depends on the time of year and where you are, but typically with a spa cover reapplying every 30-45 days is sufficient to maintain a maximum level of UV protection.

I have a 3-year-old car with a factory top that is starting to show its age. I was told the top material was vinyl but it looks and feels like fabric. What is it and which 303® product should I use?
The vast majority of aftermarket replacement tops, are a specialized type of VINYL. Manufacturing involves an extrusion process then top-coating followed by an embossing process. It is the embossing process that provides the desired texturing which some might consider a fabric look. (The top-coat is for extra UV protection and mildew resistance). So, the 303® product you need to restore that "like-new" appearance and it keep it that way is 303® Aerospace Protectant™, recommended for both the top material and the clear vinyl.
