CASTROL AND HONDA BREAKING NEW GROUND

Castrol Motorsport completed a debut double win in Sunday¹s 11th round of the World Superbike championship at Oschersleben, Germany as Castrol Honda team rider Colin Edwards took advantage of a new, four-stroke development oil.

The oil contains an anti-friction system, unique to Castrol, which offers increased power and improved clutch efficiency.

Following extensive tests at the Honda Racing Corporation in Japan and at Castrol’s own laboratories in the UK, the oil made its debut at the gruelling Suzuka 8 hours race on August 3, sharing success with technical partner Honda.

“We now hope that this technical contribution from Castrol will be able to further assist Colin Edwards’s efforts to regain the World Superbike title,” said Castrol’s Motorsport Technical Manager Lee Morton.

He added: “The Castrol Motorsport team constantly look for areas of improvement which could deliver that extra performance required for success. It is through these advances in technology that Castrol can provide maximum performance for road machines with its R4 Superbike product.”

Castrol Honda’s Edwards commented: “For the past few years Castrol has been testing with us and developing product and the performance of that product can only be judged by race results–it doesn’t get better than two wins with this new oil’s first World Superbike races.”
