Fuel system cleaners

[TheBaker]

Are these reccomended?

I saw them in halfords the other week and could do with improving my MPG(And I don't know the state of the fuel system, probs poorly like the rest of the car) thinking these might help I'm thinking of getting one, and I've got 600+ mile round trip this weekend. I'm just concerned if there could be any bad effects?

One thread from a search on google said it they could clean out the natural seals of the engine?

If so any product reccomendations?

And also, how much fuel does a 92 NA tank hold?

Thanks.

I used Redex fuel system cleaner last Friday and the difference was definately noticeable. My idle is a lot better and I feel a bit more torque in the low revs.

Fuel tank holds 55L - add the Redex to an almost empty tank and then fill it up.

I use Redex in all my cars -probably twice a year. It does work if you've not done it for a while and never had any problems using it.

Cheers guys.

Just put some Redex Advanced and a full tank in.

Hopefully it will improve the MPG a little, maybe see 200 miles a tank.

I have had a couple of cars which have appreciated a dose of injector cleaner.

Had a crx many years ago and had dieing revs issue. I put it in to a specialist garage and apart form clean the intake they put a couple of stp bottles into half a tank, they said it gives it a good clean that way

Had a golf gti and when you came to a stop at a junction the revs would die. Put some stp injector cleaner into half a tank, problem solved.

Since then I have always given my cars a dose every year as part of the service

vw main dealers use forte treatments i use them as engine flush and fuel cleaners in my taxis and with no bad side affects, all taxis in access of 400000 miles .
when i got my 2 i did a compression test
no1 153
2 151
3 146
4 151
i put a full bottle of forte injection system cleaner to a half tank of fuel,i checked compression about 2 weeks later and i now have 181 to 183 across all cylinders
i use these on a regular basis and i all ways add a flush before i drop the oil.

Well, I managed to do 25 miles plus a trip to Solihull from Edinburgh on a full tank inc the cleaner with still a bit left, gotta say I'm amazed.

It must be the slipping clutch with all the clutch work in the town driving that's burning all the fuel.

Will be interesting to see what it's like with town driving to see if it's really helped.
