I just had an oil change and was told that I should have an engine flush. I have a 2000 Neon with 145000. Would you recommend this? Anything else you would recommend that can keep the car running good for awhile longer?

Well, not every engine needs an engine flush...

If you have driven it short distances a lot or allowed the engine to run too cold (like with a bad thermostat), you might have some sludge in there, but unless they pull the oil pan and valve cover, they won't get most of the sludge anyway.  From my perspective, an engine flush is a waste of money.

Have you driven short distances a lot, or on a regular basis?  Does the engine temp (if you have a gauge) run up around the middle of the gauge?  If so, the engine is probably clean, but I'd make sure I had an operational PCV system. Regular oil changes (3000-5000 miles), a warm running engine, and a well-serviced PCV system will go a long way toward keeping the sludge under control.

A cooling system flush might be in order, particularly if it hasn't been done every 30,000 - replace the radiator cap each time.  And don't forget the timing belt - it was supposed to be changed at 105,000 miles.  The spark plugs should have been replaced at 90,000 miles.  The drive belt for the alternator, A/C, and PS pump should be replaced periodically.  Keep the battery terminals clean, etc.

Something else that is a waste of money is a power steering flush, but a lot of oil change outlets offer it.  The interesting thing is that you really don't know whether they did it right or not.

I try to stay away (mostly) from the things that aren't in the maintenance guide that the manufacturer published to go with the car.  The folks that built it are the best source of information.
