Steer well clear of all of this crap.

The last thing you want to be doing on a 12 year old engine is blowing lumps of carbon deposits off. These are probably what are sealing the valves on the thing.

Just using good quality fuel and regular oil changes are all that are needed. These gimmicks will do more damage than good in an engine of that age.

Optimax has cleaning agents for the injectors in it anyway. No need for anything harsher than that.

 

Hi mate.

A chap at my work has used some injector cleaner and his car is a H reg Toyota MR2 with 70'000+ miles on the clock. It has improved his lower end torque, well worth the money from what I hear. :naughty:
From what i've heard, an engine with a higher engine is not worth using oil flush as it removes the muck that is covering minor imperfections (the dirt acts as a protection for the engine) and can cause more damage than its worth! Someone correct me if i'm wrong. :err:

 

I used 10k boost and can reccommend it. No problems whatsoever.

 

I used it on my old 205. Didn't do any harm, but didn't seem to do anything at all. Don't expect to be able to notice any difference.

 

i used injector cleaner in mine, it both quietened the engine down and helped with lower down torque I still use it today with every tank full

 

Which brand do you use?
Is it redex by any chance?

 

Yes mate

 

I've always used STP or REDEX injector/fuel system cleaner in all my recent cars on a regular basis, to good effect. Save your money on the 10k boost. If things are that grunged then it's time to whip off the TB and get jiggy with the white spirit and toothbrush (an old one is best!).

DD.

 

I can't imagine getting 'jiggy' with a toothbrush... does it require musical accompanyment?

:bgrin:
