If your trying to clean off the carbon in the motor on the valves it kinda works. You need to use a lot of it tho and in conjunction with top tier fuel for it to really work.
I work at a gm dealer and I use the gm top engine cleaner (basically same thing) and it does a good enough job to help eliminate a p0300 (random misfire) code due to the carbon build up. The gm bulletin specifically says tho to use top tier fuel in conjunction to fully eliminate it coming back.
I had a similar thing happen in an old car when I started running diesel oil. The cleaning additives in rotella -t synthetic managed to clean out some deposits that were apparently clogging holes and started dripping oil. That’s what you get when you try to give your baby nice things. Went back to dinosaur oil.Either it fucked up her engine or the carbon deposits were the only thing holding the oil in. [emoji23]

Lol. Yeah, she doesn't leak, and there's no smoke, but the oil drops about a quart every 1000 miles. I went back to dino oil from synthetic and I've been playing with weights... I'm at 10w30 now. We'll see how that goes.I had a similar thing happen in an old car when I started running diesel oil.

Around 123kHow many miles does your rig have James?
I would hot soak it once a year in my scramble to get rid of carbon deposits and stop the spark knocking. I’d pour it into the carb slowly until the engine would stall. Let it soak for 10 minutes, then fire it up. It would smoke and steam like the house was on fire, but after letting it run for a bit, it was good for 5-7k miles.

Hurry up and go knock on some wood. And don't hot soak with Seafoam.Mine just turned 155.800 and does not burn that much.
