Just watched Fifth gear
Very interesting, they were checking if you can regain the cars Horsepower to original spec
The car was old but in good condition, say 15-20years, an early quick VW Vr6 ?
Original spec stated 190hp
Tested now 177hp on rolling road, they put it on the road after every stage
Added Redex injection cleaner, added 8hp
Changed oil and new air filters, added 2-3hp
new plugs and HT leads, added 4-5hp
they got it back to 197hp
At the cost of approx. £300
I was amazed I might have the exact amounts wrong but the final figures were brilliant
He said just adding the injection would be enough to make a difference

I seen that episode too so off I went and bought the fuel additive, the expensive part of proving if it worked though is the rolling road!!:(

Just watched this myself tonight too and agree you wouldn't have thought a dash of redex would make that much of a difference although I did wonder about ambient temp changes etc. effecting the RR results as the baseline figure was taken the week previous but none the less an interesting article.

I use Redex every few tanks, fantastic stuff, i think i will change the spark leads now based on that

I didn't take note what Redex they used
I assume injection cleaner Redex means it covers all types of carburettor's.
I was thinking bike and sprite
