403  Protect-O-Lube® Plus
   Fuel Stabilizer Concentrate


A modern fuel stabilizer concentrate, Protect-O-Lube Plus is recommended for use in diesel fuel* or gasoline engines to increase performance, reduce downtime, clean and lubricate critical engine parts, neutralize the harmful effects of engine acids, remove carbon, gum, sludge, and varnish from valves, cylinders, pistons, fuel injectors, carburetors and all interior surfaces of an internal combustion engine.

Composition:Protect-O-Lube Plus is blended from carefully selected prime “heart-cut” neutrals, conditioners, acid neutralizers, moisture absorbing agents, friction release compounds and pure mineral base top oils.

It also contains:


Rust Inhibitors

Foam Inhibitors

Oxidation Inhibitors

Dispersant Additives

Oiliness Additives

Cleaning Additives

Corrosion Inhibitors

Oxygenated Solvents

Performance Characteristics:
Neutralizes Acidic Combusion By Products
Improves Combusion and Fuel Economy
Reduces Fuel Waste and Emissions
Neutralizes all Hamful Engine Acids
Increaes RPMs
Reduces Frictional Drag
Eliminates Piston Ring Stricking and Scoring
Eliminates Sticking Values
Cleans and Lubricates Fuel Injectors and Carburetors
Eliminates Carbon, Varnish and Sludge

Protect-O-Lube Plus is recommended for use in diesel*, gasoline of all grades including ethanol blended gasoline and kerosene fuels, to neutralize the corrosive effects of engine acids created during combustion from sulfur contained in the fuel. It also absorbs moisture, prevents icing and stalling, removes carbon, gum, sludge and varnish deposits, improves combustion, cleans injectors and carburetors, lubricates top rings, frees sluggish valves, improves ring flexing, improves performance and reduces downtime and maintenance costs. Protect-O-Lube Plus is also excellent in compressor oil to free carbon encrusted valves.

This diesel fuel additive does not comply with federal ultra-low sulfur content requirements for use in model year 2007 and newer diesel motor vehicles or model year 2011 and newer diesel nonroad equipment engines.

Protect-O-Lube Plus can also be used to free frozen bolts and nuts, or applied as a superior rust preventative on weapons, fishing tackle, farm implements, fertilizer storage and application equipment and similar uses to prevent oxidation and corrosion.

Treatment Rates:Protect-O-Lube Plus is recommended for optimum overall performance at a concentrated treat rate of 1:300. However, a treat rate of 1:100 may be used to achieve faster cleanup for engines with excessive carbon and sludge. Treat rates as low as 1:1000 provide sufficient keep-clean performance as a maintenance dose.
