Hi Everyone,

Found a bottle of this stuff in my shed today, dated from 2007 and still new and sealed... must have forgotten about it all these years after moving house. It's Wynn's brand... "inject-a-clean". IIRC, someone gave this to me but never bothered using it with the old car.

Not sure if I should be using this stuff in a 2011 FD Civic or not. I have 25,000KMs on the clock. I've been reading articles online and was told it would be better to fill up with 98 than put this stuff in? Also saw that this stuff might just be kerosene or diesel as well???

I fill up with 95 now, not touching e10 with this car.

Any advice would be great.
