Gasoline & E10 Ethanol Fuel Storage Guide

Modern gasoline degrades rapidly — especially ethanol-blended fuels.

How Long Does Gasoline Last Without Treatment?

• Conventional gasoline: 3–6 months
• E10 ethanol fuel: often less than 90 days
• Reviews on stale gasoline recovery

Ethanol accelerates:

• Moisture absorption
• Oxidation
• Phase separation
• Gum and varnish formation

How PRI-G Extends Gasoline Storage Life

PRI-G is engineered specifically for gasoline and ethanol blends.

It works by:

• Interrupting oxidation reactions
• Preserving volatility
• Reducing carbon deposits
• Improving combustion efficiency
• Helping restore aged fuel when possible

Manufactured by Power Research Inc.

Does PRI-G Contain Lubricity Additive? No.

Gasoline engines do not require the same lubricity enhancement as diesel engines.

For diesel and kerosene storage, use PRI-D.
