It’s always hard to quantify something you can’t see. Fuel additives are one of those things.
So we’ve been running Redex One Shot in every tankful for the last three months. Switching from premium fuel to the normal stuff in the process. As we mentioned in our previous post there are cost saving benefits by doing this, albeit negligibly small.
Is it worth it?
We wanted to test Redex in something that truly needed it, a car that would see a benefit. Hence why we chose the nearly 19 year old Peugeot 106 GTi. AKA #PROJECT106GTi
It’s definitely upped the MPG we’re getting. A high revving 1.6 litre with a 45 litre tank is rated to give roughly 326 miles according to Parkers. Doing the math 33 MPG works out at 387 miles per tank, the lowest we hit was around 360 miles…with some to spare.
8.1 litres per 100 kms measures 364.5 miles, which is 35 MPG. For arguments sake we’ll say 34 MPG is the average since using Redex.
Official ratings for the 106 GTi from the factory were 33 MPG. Which means a 19 year old, 103,000 mile buzz box of a hot hatch is performing as efficiently, or even more so than when it left France.
Handily, Redex make these One Shot bottles measured out exactly for each tankful of fuel. They don’t however make it easy to open the bottles.
The bottles that say ‘remove foil seal completely’. There’s no tab to pull, no edge to get at. We ended up breaking the seal with a key and just tipping it in.
But a pull tab would be nice…and helpful. From memory i’m pretty sure the larger bottles have pull tabs…
It doesn’t hurt. It’s like with any car maintenance, from cleaning, looking after the paintwork to having your vehicle serviced. You do it to prolong the life of your car and to keep it running at its best.
Whilst it increases MPG it won’t save you much money, but if you truly want to look after your pride and joy what’s £2.50 of Redex per fill up? It will keep your injectors clean and fuel system in tip top condition.
We’ve proven it will even help an old battered hot hatch.
