Engine additive and cleaner

[Dazecoop]

I use Wynn's injector cleaner / clean burn products form Halfords, maybe once every couple months. Have done for years, on almost all my cars. Never had any bad effects from them.

The only thing I have noticed is my Land Rover got noticeably better on fuel on the tank that I used the clean burn, so its gotta count for something. I haven't used on my Peugeot yet though, but might treat it over Xmas
