Former Stig Ben Collins is one of many advocates who have Tested and Recommend BG.

Chemical research company BG Products have been developing solutions to engine deposit and oil sludging issues for over 40 years. Industry guru Frank Massey uses and recommends a BG Products EPR flush and BG System Cleaner on every serviced vehicle - "The products work. The effects are real."

Declaring himself "normally sceptical", Motoring expert Quentin Willson has said he's impressed by BG's range of fuel system cleaners. In his Sunday Mirror Motoring column on 9/11/2014 Mr. Willson featured BG44K and BG244 as recommended products to improve MPG, engine responsiveness and reduce smoke.

Former Stig, Ben Collins tested BG with objective data provided by a rolling road dyno before and after the BG Powerflow treatment. The effects were significant. Horsepower was 22% higher on the test vehicle and post-service there was additional 43 ft/lbs of torque.
