#149 of 158 sounds like a plan to me

0patience regularly sends oil from big hog diesels to analysis from his fleet, and it makes good sense to me.
myself, the old procrastination bug has me, especially since I don't see "test me!" kits on the shelf to make it easy to send in a sample. it would be nice to chart... however, since I exceed in all cases and greatly exceed in others the manufacturers' suggested maintenance, it's not likely to show me I'm missing something important.
surely makes more sense periodically taking this checkup that to pour all kinds of OrblSlop (tm) at scalpers' prices into the crankcase and try to flush goo that isn't likely to be directly reached by a flushing machine for big money each time.
I can stand on a bridge and tear up $20 bills to the same effect.

Don't tear up those $20 bills, send them to me!
#151 of 158 why, soitanly

you want the ones with the picture of Daffy Duck on them, or the ones with the picture of Groucho on them? those are about the only ones I'm seeing, lately

Well let's say your oil analysis does show a problem. What can you do about it anyway, an exploratory tear-down?
In fleet service, decisions one makes based on oil analysis has a huge effect on many vehicles, but for one car, what effect can you produce over the normal life of the car? Our cars aren't like big fleet trucks, they aren't expected to run 500,000 miles. They aren't built for it.

I agree with Mr Shiftright, but the oil analysis can be a tool to use. I wouldn't use it regularly on an automotive application, but in some instances, where you suspect something, like a leaking injector or coolant getting into the oil or something like a timing chain coming apart, the analysis could point you in the right direction, to let you know that you need to do a tear down, especially if you are the person who will do the work.
#154 of 158 well, you can decide to start saving money, or trade it off

or if you have a heavy shop and ten other cars running, you could decide it's time to play with the internals on this one. got a guy at work with 30 cars stored at the folks' place just waiting his time to tear them down and fix all the piston slaps and buzzing trannies and such. being an apartment dweller with no power in the garage, I don't go there

WEll, that's true, as a diagnostic tool for an elusive problem that already exists, I could see the value of an oil analysis---however, I can't offhand think of a diagnostic situation that couldn't be handled by more immediate means--liek pressure testing or a CO test in radiator water, etc.

Directly from GM......................
Info - Engine Crankcase Flush #02-06-01-028 - (08/09/2002)
General Motors is aware that some companies are marketing tools and equipment to support engine crankcase flush procedures. GM does NOT endorse or recommend crankcase flushing for any of its gasoline engines. Analysis of some of the materials used for crankcase flushing procedures indicate incompatibility with GM engine components and the potential for damage to some engine seals and bearings. Damage to engine components resulting from crankcase flushing procedures is not covered under the terms of the New Vehicle Warranty.
I rest my case.
#157 of 158 And any other brand of engine!

Thanks, Batman. In my opinion you have said it all, concerning engine flush products.
May 17, 2003 (11:59 pm)
the only way an engine should be flushed is if it gets embarassed. and then it earned it.
