It may be a placebo effect, but the idle is smoother, acceleration seems smoother and all-in-all, it wasn't a particularly expensive service. I am also glad I replaced the thermostat and did the coolant flush. With these record temps, I want to ensure the cooling system functions as it should. I suppose I should feel lucky my thermostat gave me 148,000 km, they appear to be a common replacement item on the F3x.

The issue is you only get what liquid catches on the carbon on the way by. If you could soak the crap out of it, then it would break loose.
Great video BTW.... |

i've never heard this before. the main benefit is similar to running meth. It's not the fuel that preventing carbon. It's adding additional injection in the charge pipe or intake manifold that sprays fuel over the valves to keep them clean.
carbon deposits are primarily dependent on oil and piston ring tolerances. fuel has little effect. |

To some extent that's what happens. If you sprayed the cleaner into the intake manifold with the engine off it wouldn't be evenly distributed on the valves and manifold surfaces. That's why it's sprayed into the manifold with the engine running. Doing that most of the cleaner gets sucked into the cylinders, that's why the entire can of cleaner is used, rather than just a spritz or two like when you're cleaning the MAF sensor. Not a lot of cleaner ends up coating the valves and manifold, but it's so highly concentrated that it doesn't take a lot. The hour waiting period allows the cleaner to do its job, the highway drive right after that purges the cleaner and the deposits that it removed.

Agreed, just saying that the benefit of no carbon deposits with both systems is typically due to requiring additional injection points before to the intake valves. The fuel itself in either case doesn't prevent carbon build up. How could it?

Gotcha. I guess i'm thinking more of the oil deposits and blowby still having an effect.
