The XP range are pure race oils developed through years of R&D in the demanding world of NASCAR.
They do not conform to any road approval rating, which means they are formulated to win races.
The XP oils have maximum anti-wear protection and friction reduction chemistry to help protect your engine and free up power, at the expense of a shorter service live. The best choice for heavily tuned engines or where you are chasing any incremental improvements in performance.
The XP mineral oils are a perfect race choice where temperatures are not high, and there is a need to change oil frequently due to the risk of either fuel dilution or dust contamination.
Available in 5W-30, 15W-50 and 20W-50 grades.
Make sure that you have warmed up the engine so that the oil is warm before you drain it down. Top up with the right viscosity recommended by the manufacturer or your engine builder – Driven XP oils are available as a 0W, 0W-10, 0W-20, 5W-20, 10W-30, 10W-40 or 15W-50 viscosity. Do not exceed 25-hour service intervals for endurance racing or 1,000 miles for shorter race events.
Change the oil if it starts to go black as that typically indicates that fuel has interacted with the oil. We recommend to change the oil filter after each race weekend and top up with fresh oil. Change oil every third race weekend (see the colour of oil). The XP range of oils are not designed to sit in engines for long periods of time.
The mineral range has high ZDDP levels and low detergent levels giving them a service life of around 500 miles. The XP4 and SR50 are good options for vintage engines where high detergent levels found in modern oils can cause problems.
