For those seeking the ultimate in performance and the value that comes from engine preservation, you need look no further than Bishop’s Original treatments and additives. Our unique formulas will not only bring you reduced fuel consumption and increased engine life, but will also offer a cost-effective defence from potential mechanical complications and subsequent repairs.

Bishop’s Original treatments provide a simple solution to the interfacing metal friction and high heat produced in all engines. The unique chemistry of the proprietary formulation brings you the long-lasting lubrication and protection that cannot be found in simple oils and additives.

Through 30 years of official testing and consumer use, our treatments have been found to provide unrivalled levels of performance and protection, with leading experts declaring inventor John Bishop’s formula as ‘the greatest breakthrough in lubrication technology since the discovery of oil.’

... The treatments were added at 96,646 miles, and after only 300 miles the ease which the car would ascend most hills in top gear was undeniable, while the engine's performance was significantly quieter and operated with greater horsepower... Henry Jeffery, Cranbrook
