Give your engine the treatment it deserves

STP Petrol Treatment and STP Diesel Treatment are specially formulated to improve engine performance and can reduce fuel consumption by tackling the build-up of harmful deposits.
When used regularly, the powerful cleansing agents in STP Petrol Treatment can improve the quality of petrol flow to the engine by removing the build-up of dirt, gum, varnish and other deposits, which are all too prevalent in everyday fuel.
Added to a tank of petrol every 950miles/1,500km, the product also helps to keep carburettors and fuel injectors clean, reduce intake valve deposits, fight rust in the fuel system, reduce exhaust emissions and equally useful once winter comes, STP Petrol Treatment will fight fuel line freeze by removing water in the combustion process.
Whilst higher octane and other ‘premium’ fuels claim to offer the same benefits, the additives are less concentrated than those in a bottle of STP and more often than not their use is negated by price.
Equally effective at cutting potential long-term costs is STP Diesel Treatment, which like the petrol variant, is specially formulated to remove varnish, carbon deposits and water from the fuel system, to prevent poor performance, corrosion and fuel wastage.
Ideally added every 1250miles/2,000km, Diesel Treatment also contains a cetane improver to enhance cold start performance, and will restore lost power and performance whilst reducing smoke and noise in the process.
Both fuel treatments are available in a 250ml bottle and are priced at RRP £3.99 and £4.49 for petrol and diesel respectively, which when added as recommended, amounts to a cost of just 2.4 pence per mile and 2.8 pence per mile.
Both treatments, along with STP’s full range of engine care products, are widely available nationwide from forecourts, major stores and accessory shops. For more information, see stp.eu
