Gasoline Phase Separation and what is it!

Gasoline phase separation is a term used to describe what happens to water when fuel enters a storage tank. Its something that generally happens to E10 or E15 blends of ethanol fuel. In order for fuel separation to occur it takes three components: water, ethanol and gasoline. When ethanol and water reach their saturation levels ethanol attacks the water and spreads it throughout the tank causing water to be found almost everywhere.

When ethanol attaches itself to water molecules it leaves two distinct layers in the fuel tank, a gasoline only layer near the top and an ethanol water cocktail layer at the bottom. The gasoline only layer may lower the octane level and cause engine knock, whereas, the ethanol water layer may be the reason why the engine won’t run at all.

PRI and PRI-G independent laboratory tests show how to prevent phase separation in ethanol blended gasoline!

Test show PRI-G fuel additive easily solves gasoline phase separation and dilemma.



The results are in. Independent laboratory tests by Intertek Caleb Brett Laboratory confirm PRI-G capability to inhibit phase separation in E-10 gasoline.

PRI-G is tested, verified and will safely deliver the much needed insurance against phase separation when using E-10 gasoline in all engine types.

How was PRI-G tested?

First, water was progressively added to E-10 gasoline to determine the point of phase separation.

Second, a sample of the same fuel was treated with PRI-G, and the test repeated. Not only did phase separation not occur, PRI-G continued to work as additional water was added.

PRI-G contains no harsh alcohol components. Most engine manufacturers warn that the use of alcohol-based consumer additives can be damaging to engine components.

Additionally, only laboratory tested and proven chemistry should be used when treating modern fuels for protection against phase separation. Using unverified products can have disappointing results.

Be safe rather than sorry. Be safe with PRI-G.

Bob Stearns, Boat Digest Magazine, “Are You Ready For E-10”, September 2006:

For over six years now, I’ve been adding a very small quantity of PRI-G to the tank every time I refuel. PRI-G is a non-alcohol, long-term fuel stabilizer, which is especially important where E-10 is concerned. But also very essential, PRI-G is a carbon dispersant, particularly good for outboards because they are sensitive to carbon buildup in the cylinders.
