Silkolene

PR Oil Supplies Ltd | Silkolene

Silkolene Pro Boost
High performance, efficient octane improver designed to combat pre-ignition - often called 'pinking' or 'knocking'. Contains a unique blend of synthetic organic chemicals that reduce upper cylinder wear and burn cleanly without leaving deposits in the combustion chamber. Helps to a 'keep clean effect' in both carburettor and injection systems and reduces icing in carburettors. Improves acceleration and lowers fuel system corrosion. Is fully compatible with all petrol and does not attack fuel hoses or filters. Has been successfully tested in a wide variety of car and motorcycle engines, including 2-stroke. Suitable for all petrol engines and all types of fuel. Does not contain lead or aniline and can lead to a reduction in emissions through a more complete combustion of the fuel. Improves throttle response and facilitates cold starting to reduce heavy exhaust gas pollution when the engine is cold.

Silkolene Comp 4 20W-50
Synthetic ester based 4-stroke engine oils, with Electrosyntec Technology, for all high performance motorcycles. Has an exceptional stay-in-grade formula that protects engines and transmissions and combats wear and friction on all critical load surfaces, even at high temperatures and during cold starts. Formulated to meet the needs of both air and water cooled 4-stroke engines. COMP 4 20W-50
Particularly suitable for use with tuned racing engines or high performance units being used in hot climates. Has excellent high temperature-viscosity characteristics to help protect highly stressed components and maintain consistent oil pressure and shear stability. Also offers excellent ‘stay-in-grade’ performance and long lasting corrosion resistance, even during periods of intermittent use. Suitable for many vintage and classic engines where monograde oils were originally specified. Also ideal for larger air-cooled V-Twin engines and in roller bearing engines.
