This morning I started my engine and had some rough idling on my way to fill up for the day, didn't really think much of it because Hyundai engines are just like that. A few miles in I got the dreaded CEL, had the codes scanned and came back as a lean condition under higher load. I've done a ton of idling lately trying to not freeze my arse off combined with lots of high RPM pulls trying to get unstuck in snow and have been kinda lazy with the fuel treatments lately. Picked up a bottle of techron thinking it won't hurt and GDI engines are know filth generation machines, the CEL went off after about 100 miles and a 1/4 of gas. Tried some foot to the floor pulls on the highway on ramp and made 0-60 in 8 seconds flat, (better than it's rated) which tells me there's no fuel starvation.
This stuff really does work.
