The owners manuals says you shouldn't use engine additives as they are not nessesary, so I stay away from them.oldacura said:

Professional cleaning and flow testing is the only way to ensure that your injectors are doing the job as designed. And, at the same time, you get to replace the various seals and cushions and O-rings and so on that deteriorate over time.supplant said:
To get back to original performance, assuming compression is OK, three things need to be right: Clean throttle body, new spark plugs, and clean injectors.
What exactly does "cleaning throttle body mean?" Is it a difficult and expensive process? I ask because you never really see anyone advertising it, but you see 'Fuel Injector Cleaning' everywhere.
Does Throttle cleaning solve "piston slap?" described below.
Engine noise - Carbon buildup on the piston rings may cause piston slap. The fix is to clean the carbon using GM Top Engine Cleaner sucked in by way of a vacuum port on the throttle body. (1991-95)

The throttle body is located at the front centre of the engine, identifiable by the intake air and throttle cables attached. Essentially, it consists of an aluminum housing with a large buttterfly valve. It is cleaned by taking it off the engine, and using solvents and a brush, followed by a blast of compressed air. I have a feeling that if you do a search on Throttle body cleaning, something will turn up in the forums.
Piston slap is caused by either badly worn pistons/cylinder bores, or by stuck piston rings. The GM Engine Oil Supplement or top Engine Cleaners will sometimes help clean out the ring grooves to the point where the rings will work properly, and the slap will go away. If your engine has had regular oil changes (quality oil), you most likely don't have a problem with carbon in the ring grooves.

1) no problems with 44K .
2) no noticeable difference over it and two cans of techroline other than price
3) change your A/C filter to be sure leaves and things aren't in there decaying.
4) Lysol works fine, trust me. I had a jeep that got mildew and Lysol was the ONLY thing that stopped it, not even bleach worked.
5) Many Legends blow a little smoke on startup. The key is oil consumption per 1000. My '92 used a half-qt at 5,000 miles even with 115,000. My '94 uses a qt every 2500 but it wasn't new when I bought it and I don't know the history the first 25,000 which is most critical.
6) piston slap and carbon knock are two different things. Use GM upper engine cleaner to knock carbon off the pistons or free up captured rings like 91-93 that didn''t go through the ring recall. Piston slap from worn pistons usually requires a rebuild and new pistons although if the clearances are good except for the skirts, one can gently tap the skirts out to tighten them up on a cheap repair. Persoanlly if I am to go that far on a high mileage car it makes more sense to replace the pistons to prevent a crown failure. With a $40,000 price on new quality Acura models it might be wirth rebuilding an engine on an old one assuming that the body and leather etc are clean. Pays to take care of them - that is where things like 44K and changing the oil every 3 - 4 K come in.
