What are the advantages of using special diesel engine oils?
These engine oils contain a higher proportion of cleaning additives to prevent the formation of deposits and also contain chemical substances which coat particles of dirt and prevent the formation of agglomerations. These engine oils are therefore able to keep any soot particles which get into the crank gear in suspension and prevent the formation of deposits which impair performance.
Can Oil Additive or Engine Protect be used for motorcycles as well?
At 20 ml per litre engine oil, this additive has a beneficial effect on wet clutches and prevents clutch slip. We do not recommend Engine Protect for general use in wet clutches.
