Costco often do an offer on 3 bottles of Redex. Basically about £12 for 3 big bottles. Each bottle does 4 tank fulls. I then run them through both trucks until I run out, then repeat the next time the offer is on.
When Rick and I changed the head my injectors were nice and clean, and the same when I had to replace no1 injector a couple of years ago.
I don't think its worrh spending on the expensive stuff, but as I run veg in both T2's, and did read it tends to gum up, places in the system, I am happy to use it when it is cheap.
