It is sold under various names here. Paint thinner, solvent, white gas, camping fuel, parts cleaner, lighter fluid. All are similar. The one you link is described as being most suitable for cleaning carburetors. I last had a vehicle with a carburetor in the early 1980s.

It is generally a much better approach to use good quality fuels that include proper detergents, instead of dodgy fuels that leave deposits, and require these sorts of solvents to shift.

Well i fill up at a local esso gas station, no idea how good the fuel is there, sorry for the wrong link, the one i used was the one for complete fuel system clean, injectors etc....

No problem with the link, when you look at the Redex product on the manufacturer's web site, they list all of the products (petrol, gasoline, system cleaner, injector cleaner, total cleaner) as having the same composition. It is still a solvent.

I have no idea how to judge diesel fuel quality in Cypress, but would ask a trusted local mechanic where they see there are fuel issues and where they see fewer fuel issues.
