I first started using Redex in the 1950s.
It was Free on the forecourts in those squirty cans.
This lasted a few years then I think I stopped using it.
Fast forward to1994. Used a Citroen XM for 190,000 miles. No Redex.
Also a Peugeot for a similar mileage. Again no Redex.
No injector problems with either car so for me the jury is out on the benefits of Redex.
Maybe it could benefit a poorly maintained car but do nothing for one that's well looked after.---
