UNICAT4 is part of a stable of products marketed under licence, from the Carvern Petrochemical Co. Ltd, which has been manufacturing fuel conditioning additives for over thirty years from its factory in Fort Erie, Ontario. UNICAT4 is sold through distributors and retailers.

Unicat4 field trials began in the UK in 2000. Significant improvements were experienced in the reduction of smoke across all vehicles ranging from a brand new Claas Lexion 450 combine harvester to a six year old Land Rover Discovery. The smoke reduction on the engines with no environmental control measures was a clear indication that unburned hydrocarbon emissions were being slashed. Measuring fuel economy in the works vehicles saw improvements of 7-8% over two years, and it was clear this product was justifying its usage by paying for itself again and again.
