Anyone try RISLONE before?

I just bought a couple bottles on sale at 2 for $5. I already used one on my 4runner, 125,000 miles. I can definitely expect to see a difference there, having never cleaned the system before.

However, I'm a little skeptical using it on the treg. Everybody screams Seafoam here which goes for ~$10 a bottle. I am also only at about 18k miles.

I use BG44K.

I haven't used it on the Treg, mine is a TDI anyway, but, I have used it on my Audi S4. It was almost instantaneously smoother. What got me started with it is that I was intermittently throwing a code P0431 which is for one of the cats. I would clear it and then within a few days it would be back and the car would be noticeably rougher. I put a can of 44K in and the code has not come back nor has it run rough, in fact, no code was on when I put it in and it smoothed out within half a tank.
