The item is a brand new bottle (400ml) of Forte Oil Fortifier and (150ml) bottle of seal conditioner.

Forté Oil Fortifier has been tested in a wide variety of high mileage engines. This has proven the reliability of the product in restoring performance and greatly extending the life of engines far beyond the stage where they would have required extensive repairs or a complete overhaul.

Forté Oil Fortifier is recommended for use in engines of older or higher mileage vehicles which are showing signs of wear; evidenced by high oil consumption or excessive exhaust smoking.

Forté Oil Fortifier is compatible with all crankcase fill oils, including fully synthetic, which meet the specification of API and ACEA classifications.

Forté Oil Fortifier is not recommended for use in engines incorporating wet clutches.


Forté Seal Conditioner is a synthetic seal treatment which restores the elastomer properties to seals.

A major cause of oil burning and exhaust smoking in automotive engines is due to the valve stem seals hardening and shrinking, which results in oil leaking past these seals into the combustion chambers. This condition can be treated by adding Forté Seal Conditioner to the crankcase oil.

Forté Seal Conditioner is compatible with all conventional crankcase and gear oils, including fully synthetic and semi-synthetic engine and gear oils. Forté Seal Conditioner is not compatible with aqueous and non-petroleum oil-based fluids.
