opinions and technical bumf appricated. basically i threw some red ex something or other feul injector cleaner throuigh my car that supposed to clean them up and give you better mpg and raise octane numbers. both me and my my father tryed it he has an rx8. after about 200 miles he hit a flat spot followed by alot of crap that came out the rear and since then the car has never driven better, more resposive tec so he says. and i too tbh did have something simular i took it out for a blast crap came out and it ran/runs much better, feels miore responsive etc and seems to produce better acceration higher up the rev range. it also seems to have cured the pulsing i had at full boost. should i contine to use this product to give me higher octane ratinga nd keep the injectors clean or should i pop it on the shelf and forget about it? maybe it was all in my head...? i did wonder wether the increased octane rating agreed with the car more because its a jspec and never been ajdusted ti run on lower rating english feul.

was thinking about using another product they do for cleaning cataylic convertors

Personally I reckon that most additives are little more than snake oil.....

 

.....that said, a decent fuel system cleaner could well improve things like you've just said. But there's no need for continued use - that's exactly what the manufacturers would like you to do!!

 

Use a good one once, thereafter just fill up with a decent fuel that contains the detergents already, so you don't have to keep using other additives. Job done....:sailor:
