Redex diesel, is it any good? Will it do any harm?

[Nahguam]

I was looking for ways to improve my mpg, I know driving style, tyre pressures and fuel have a huge impact but what impact ( if any ) would redex have and would it harm the car, also what else can be done to improve mpg, thanks in advance!

GK recommends Millers ecomax diesel.

Run a few tank treatments of that through and every tank after than and your engine WILL run better and you will get better MPG. Alright

The garage I use recommended the cleaner one when I have a service and about 36k, 4 services and 18 months later it's going well for me

I have some redex lying about in the garage,bought it a while back but then read its not great for PD engines?
cant find where i read it now though

i know millers is the brand of choice but as i already have the redex anyone know if its ok to use like the op asked?

millers
forte
redex

in that order, the cheaper they are the lower quality they are.

Me too, used it after a de-cat and the smoke hasn't gone a year later!

Changed to millers myself

 

[bald_eagle]

Has anyone proven that Millers actually does anything?

I've been using it for a while but am beginning to wonder if it actually makes any difference? After all, 25ml added to 25 litres of fuel is a pretty large dilution ratio...

 

[Andrewcupra TDI]

i always double dose it every time , seems more responsive

What cetane rating would that end up with?! Is it safe/ok to use at that dosage?!

I know standard diesel is 51 cetane rating, Total Excellium 53, Shell V-Power diesel is 55, and BP Ultimate 55.

What does the Millers at 1ml per litre make 51 rating go to?

I'd have thought it'd be around 55? the same as the Shell and BP?

 

[Andrewcupra TDI]

not sure but states on the bottle for an added boost double up ,

as the new bottles have the filler cap half is one shot , iirc 25ml for 1 shot 50ml for a double

 

[Muttley]

Standard dose for Millers is 1:1000, so 50ml should be added to each full tank, if like me you run your tank down to near-empty. 25ml is only appropriate for a half-tank refill, assuming the fuel in the tank is already dosed.

Millers claims an improvement of up to 4 cetane numbers.

i just fill that expansion part full then tip it in , whether i only half fill or fill to brim

guess i should put 2 lots in then for double dose if i read that right muttley

 

[Muttley]

Double dose for a full 50 litre tank of fresh diesel would be 100ml, which means filling the measuring bulb up and emptying into the tank twice, yes.
