Default Bilstein engine flush system......

Hi anyone here tried the Bilstein engine flush
machine for flushing your engines?
I haven't flush my engine so far and i have 55,000
on it. I don't know if i should go with the bilstein that
uses a machine to flush the engine or to go with
that flushing fluid that you just put in the engine
and run it idle for 5 mins then flush it out again before
putting the new oil. The bilstein machine cost $120
and the other cost $70 at Jiffy lube.
Any comments will help guys......good day

If you've been doing regular oil changes then your engine should be clean inside and doesn't need to be flushed. Even in cases where proper maintenance has been neglected and there is some sludge buildup, an engine flush can do more harm than good by dislodging deposits that can find their way into the oil pump pickup and clog the pump, destroying the engine. It can also remove deposits around worn seals and promote oil leaks.
It's usually best to leave well enough alone, and if the oil hasn't always been changed on schedule just try to do it more often from now on.
There are also machines for flushing the fuel system, these hook up to the fuel rail and the car is run directly off them for several minutes using a powerful solvent cleaner. This may be useful if the car has fuel-related problems (i.e. the injectors are known to be clogged), but is otherwise probably a waste of money.

thanks for the reply mulder,

guess your right, i have been hesitating on doing this
to my car......i do change my oil every 3,000 miles.
Change to mobil synthetic after 30,000 miles.
Notice that the car run better and smoother after that.
Planning to change transmission oil to synthetic too.....
and the brake fluid to motul......just wonder it they
will have a big difference if i go with them. I have
steel lines right now but still using dot 3 fluid.
The dealer will charge me $70 to flush it and change
the oil or i might just look for someone who can
help me.

Please be advised that non-synthetic oils are composed w/ additives & that do build up over time. If you want to flush your engine, AMSOIL sells engine flush & it is relatively cheap. All you have to do is drain one quart of oil, add engine flush, put on new oil filter, & let car idle for 15-20 minutes.
