If it's petrol from any of the major brands and busy stations then you'll be fine as most have cleaning agents in them.bandit12 said:I use normal unleaded I tried Vpower and other higher octane but didn't really notice much difference.
bandit12 said:I don't have a problem but I do a lot of short trips, was thinking of putting Redex in the tank and going for a long motorway blast to see if it made a difference.
Isn't that just swapping one snake oil brand for anotherLillywhite said:Redex is a waste of money IMHO. It may be cheap but never seen any difference when I've used it. If you want to clean carbon deposits etc. then use BG44K in a full tank of fuel. A dose is approaching £20 obtainable from Power Enhancers.

I told my learned friend that I was about to get this done and he said " Don't waste your money, use Redex if you must clean it".
Not wanting to chuck money away I Googled it and found out that Redex can potentially harm other component parts when de-carbonizing the engine, whereas this Terra-clean stuff uses a much more refined version of petroleum for about 30-40mins and prevents big pieces of carbon doing any damage. That's my understanding of it. With over 90,000 mls I thought it was worth doing. She seems more responsive and I'm getting about 38-40 mpg. Even the mechanic where I took her to wasn't sure how and even if it worked.
Yes, possibly placebo, as I didn't do an mpg calculation before.nightyard said:you sure its not placebo?
theres a thread somewhere showing how the carbon build up was exactly the same before and after the terraclean process
