Reviews of REDEX parts For Business

Redex Diesel Cleaner is the nuts, get +15mpg on my TDI on a long run compared to standard diesel, well worth it.

You add a shot every full tank and it turns normal diesel into premium with added cleaners. This means your car is always running additives through it which makes a huge difference compared to the occasional top up of the supermarket stuff. It works out as pennies per tank, much cheaper than premium diesel and you’ll see all the benefits including better economy.

I use a bottle of RedEx every few tanks in my 2015 320d, which is on about 90k. It seems to have increased my fuel economy by about 5%, tested by doing the same 200 mile route many times.

If I had a performance vehicle, I might go for the premium stuff, but I don't, so I go regular. I chuck in a bottle of redex every 5 or so tanks, which keeps them clean enough.

Try adding a bottle of redex to a full tank and see what happens.

You could always try your own additive in the tank, Redex or similar claims to clean fuel injectors and improve efficiency.

You're probably better running premium fuel and oil rather than using additives. Stick with Shell V-Power and Shell Helix/Castrol EDGE and ditch the Redex.

Redex fouls plugs.
