Modern competition oils are blended to provide superior protection for both engine and transmission components, however, in some cases an extra helping hand may be required.
Some oil additives are used even before the engine is started for the first time. During an engine rebuild, it is necessary for critical components to be installed using engine assembly lubes which provide friction and wear protective properties. These lubricants are soluble in oil and help with the initial engine break-in process.
For engines which have already been run in, there are additives which can increase the viscosity of the oil and protect the engine internals from the effects of friction. Not only does this protect the engine from damage, it also increases the engines efficiency by allowing the internal components to move more freely and therefore allow the engine to utilise the power produced more effectively. Further benefits include improved cold start protection, increased fuel economy and lower emissions.
