The Driven HR range is the perfect choice for classic road and competition cars.
They have enough ZDDP to protect flat-tappet engines with increased spring pressures of up to 30% higher than stock. The detergent levels can cope with up to 8000 road miles. The HR oils have a unique anti-corrosion pack which protects engines that see little use, eliminating the damaging effects of dry starts, and also contain an ethanol-neutralising additive to combat internal rust corrosion.
Available in 10W-30, 10W-40 and 15W-50 (mineral and synthetic) grades.
Make sure 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 HR is available as a 10W-30, 10W-40 or 15W-50 oil.
If used for racing or track days, change the oil if it starts to go black as that typically indicates that fuel has interacted with the oil.
Racing puts more stress on oils. Although the Driven HR oils utilise a more temperature-stable base stock 2 oil, and a top-quality multigrade additive, the oil will start to thin down after several hours of racing. Although the level of thinning is much less than most other racing mineral oils, it’s important to keep an eye on oil pressures. For ultimate racing applications, please use the Driven XP range of oils.
The HR range of oils are excellent storage oils as they contain specially developed additives to protect against rust and corrosion typically caused by moisture and ethanol from the fuel.
If your oil temperatures are moderate (up to 110C) and mileage / running time is limited, then the mineral range is an ideal choice. For those situations where engine temperatures are higher or the engine is run for prolonged periods, synthetics are preferred as they will last longer and are
better at transferring heat out of the engine. If the value train loadings are much over 30% compared to stock, then you should be looking at the XP range to provide the right anti wear protection.
