Is that $129 engine flushing service really necessary?

Dear Car Talk | Apr 01, 2000
Dear Tom and Ray:
Marilyn
TOM: I suspect this device is known around the dealership as the Bilstein R-2000 Wallet Flush System. And, in fact, my brother has already called Bilstein about leasing
one.
RAY: What this thing does is pump a heated solvent through your engine, presumably to wash away any sludge that's built up on the valves, rings or other engine
components.
TOM: And it's really quite unnecessary. Particularly for a car with only 45,000 miles on it. Changing the oil serves the same purpose -- de-sludgification, if you will --
and if you change the oil every 5,000 or 7,500 miles, you shouldn't HAVE any significant sludge that needs to be washed out.
RAY: While it's possible that such cleaning may help the engine last longer, the engine on a Toyota Camry should easily last 150,000 miles without flushing. And if you
followed the advice in the brochure and flushed the engine every 12,000 miles, you'd spend $1,600 on engine flushes in 150,000 miles. That's almost enough to buy a
rebuilt engine!
TOM: This is what's known in the business as a "profit center." Something the garage can use to beef up the amount each person spends per visit. So unless you've got a
very old car, and are trying to solve a specific, sludge- or carbon-related-problem, I'd skip the R-2000.
