I’ve used Redex before. Whenever i’ve bought a new car i’ll stick a bottle of Redex in the tank. I’ve also used it in the 207 now and then, maybe only once every few years, nothing regular.
But you’re apparently meant to use Redex on every tank fill.
I’ve always seen it as a one time thing, every now and then. Certainly not on every fill up. So when Redex got in touch and asked if I’d like to trial it for a few months, on the regular…I thought why not.
Today the Redex goody box was delivered. 6 x one shot 90ml Redex to tide me over for the next three months.
The car of choice…well, it naturally has to be the oldest car in the fleet. The PROJECT 106 GTi. I didn’t see much point in using it on a newer car, so lets give it a challenge. An 18 year old, high revving engine with just over 100k on the clock.
Now, my main question was that most premium fuels nowadays have cleaning agents built into them. So why would I need to also use Redex?
As i’ve always been concerned about the build up of carbon in the 106, because it’s an ageing car i’ve tended to always use Shell VPower. Now and then i’ll use 95 ron, but for the most part it’s VPower all the way.
In Shell’s latest offering they’ve added ‘DYNAFLEX’ 30% more of the stuff. That apparently helps clean your engine in the same way Redex does. But there’s no actual quantity given, it could be microscopic levels.
So is it even needed at all? And will I feel any difference?
This is what we aim to find out over the next three months’.
