I pose, as means of proviking discussion, the effects, be they positive, negative or indeed totally placebo effect that Reddex has on an engine. It's an interesting point as I have poked around the internet looking for an answer, and found literally every answer! 'Is Reddex worth using?' seems to be the automotive equivalent of 'is there a God?'}

Opinions, hearsay, what some bloke's brother's mate in the pub said all welcome...  as are facts/proof, if anyone has any

I'd spend the money on a pint instead

It has a place in the world, but find Wynns injection cleaner more effective on an Omega

Good thoughts.

Pissy is currently on a bizarre mix of old possibly stale petrol, half a tank of Shell Optimax, and a bottle of Reddex.

Out of interest, she's currently running at 19mpg. Though that's basically exclusively stop-start town driving, with only a short 3minute squirt of 50mph max between suburbs to the town centre two or three times a week. Will be driving to the Lake District tonight, so hopefully a lovely long run will see that climb significantly. After the tank has been practically emptied, will give her another fill up, probably with Optimax again, some Wynns, then changing the old rusty fuel filter. (it looks like a baked bean tin that went down with the Titanic)

How's everyone else's mpg, and with what additives, on what fuel, what driving style?

I'd say that 19mpg for the kind of use your car is is getting, is about right. SWMBO managed to get mine down to 16something but she has a digital right foot ....On or OFF

I asked a similar question a while ago, DBG. I cannot remember what responses I got (old age and fading memory?), but thinking about it, when it was customary for garages to have Redex dispensers by the pumps - penny per shot, one shot per gallon - it was supposed to lubricate the upper cylinder areas. Nowadays, with the sinful (not!) lead having been removed from petrol and the valve stem clearances opened up to provide the stem lubrication that the lead used to, the cylinders get enough oil that way, so surely no need for additional oil?
I do concur that an occasional petrol treatment for the health and well-being of the injectors is worth doing, though.....

Personally I use Cataclean and would recommend using it at least once a year ideally a month before the MOT is due 

I've also heard good things about something called BG44K been meaning to try it at some point.

[Varche]

I remember using Redex many many years ago(still have the rest).

Picture the scene. Living in a town on a terraced town house street. Changed spark plugs and filters and oil at kerbside. Put a generous egg cup full of Redex down each bore (read somewhere it was good at loosening up piston rings!). Started it up and it was a still day. Clouds and clouds of blue smoke. Puttered off as quickly as I could to the outskirts and drove along the edge of the golf course. Turned around and came back and the street was still full of blue smoke.

Can't say whether it worked or not.

MPG from our 2.5 was 23  for an average of 23 mph. The 3.0 was 24 for an average of 23mph (both over a year). Lots of twisty hilly roads.

You not suppose to drink it James. 

Although that might explain a few things. 

[Nick W]

My 3.0l auto estate averages 24-25mpg in day to day use. That's mostly my 7mile commute, about 50/50 traffic and dual carriageway. On a decent run it does about 28mpg with no attempt at driving economically.


I did once see 33mpg coming back from Beaulieu, but we didn't exceed 50mph for the whole trip.

[amba]

Similar MPG on mine Nick,but I never bought the car with any false illusions of returning much better.

Big engine/big loud pedal/plenty of comfort, so what more can you ask for ah 

[Nick W]

It's better than the manual 525 estate I had, and the 1.8GDi Legnum was little better on the motorway and much slower.

[Jimbob]

I bung in some Forte gas treatment every now and again, does make difference.

[tigers_gonads]

Used to love pouring redex down the barrel of the carb on my old escort and pishing the locals off with the clouds of white smoke 
Nowdays, I just bunge a can of injector cleaner in quarter of a tank of petrol about once a year and go for a blast up the M62.
Does the trick 

As for MPG
I'm lucky to see 16mpg around town in my estate but that is running on LPG.
Best I ever saw on petrol was 24mpg @ 50 - 60mph coming back from Newark one quite night.

Always shied away from a second car but since I have been using the lads corsa cdti for the last 3 months, we have saved 240 quid on fuel compared to what we would have stuffed in the omega 

50mpg vs 16mpg around town is a no brainer imo 
And I don't pish around in the little corsa either 

[aaronjb]

You could probably lease a tiny diesel for less than you're saving on fuel, tax and servicing included..
