MOT Emissions Pass Guarantee

Would YOU like to Guarantee your car passes the MOT Emissions Test?



Deposits quickly build up on the injectors (and inside the engine) leading to inefficient combustion, reduced MPG and increased emissions.

Use of BG Emissions Reduction /Fuel Saver Treatments with your car’s Service will Guarantee that your car passes its next MOT Emissions Test within one year of the Service... Or Your Money Back*

You may have seen adverts from the big fuel companies talking about the additives added to their premium fuels that tackle deposits. BG recommend the more dedicated, dual approach – one product for the top half of the engine, the fuel system and one for the bottom half, the oil system.

  • ‚ÄčGuaranteed Emissions Pass or Money back!

  • Because Cleaner Engines Run Cleaner

Deposits are a natural by-product of combustion and, without preventative maintenance, accumulate over time. 

BG's recommended treatment comprises one product to treat the fuel system and a second to revitalise the vehicle’s oil system:

  • Fuel System Cleaner (e.g. BG 44K® for Petrol/BG 245 for Diesel) goes in the tank to clean the fuel system. It’s vitally effective at cleaning carbon-covered fuel injectors
  • BG EPR® Engine Performance Restoration® flush softens and dissolves hard-to-remove deposits from piston rings, restoring peak compression, ensuring maximum power and efficiency.


(* Money-back guarantee applies to cost of BG Products only and excludes cars that have a modified engine or emissions control devices, or mechanical faults leading to raised emissions)
