Description
R Storage 5-Star is an ethanol-free leaded petrol, designed to be storage stable for up to three years.
Why Use an Ethanol-free Fuel?
As many classic car, bike and also boat owners have discovered, modern unleaded petrol is hygroscopic. The reason for this is the mandatory inclusion of ethanol in all premium unleaded and most super unleaded forecourt fuels. The current level of ethanol in premium unleaded is 10% – hence the name E10. This means that the future is not bright unless the fuel systems are newer than 2002 or have been updated to cope with ethanol-blended fuels.
High levels of ethanol in petroleum fuel results in increased moisture levels, which is likely to cause rust and corrosion in the fuel system. This badly affects carburettors and fuel lines, as the ethanol itself is also corrosive to aluminium, bronze and zinc typically found in carburettors. Both these issues are compounded by long periods of non-usage.
R Storage 5-Star is specifically formulated to be kinder on gaskets, O-rings and other fuel system components compared to unleaded petrol. It also contains detergent additives for engine cleanliness, as well as antioxidants and corrosion inhibitors to extend storage life. When stored in airtight, opaque fuel containers, Storage 5-Star should remain storage stable for 3-5 years.
R Storage 5-Star burns extremely cleanly and its 103 RON and 98 MON provides excellent protection from detonation. A carefully calculated amount of TEL (lead) has been added to ensure that vintage vehicles are protected from valve seat recession and/or damage to valves.
Why should this fuel be recommended over Aspen 4 for classic vehicles?
Older cars or bikes may contain fuel system parts that have become damaged after many years of being saturated in regular petrol containing ethanol. R storage plus contains components that keep these parts swollen and supple which allows them to function for longer. Whilst Aspen 4 is an amazing storage fuel, older vehicles switching to Aspen could develop fuel leaks which would be avoided when using R Storage plus.
