When an Oil Analysis costs just as much as an oil change/filter, why not just change the oil?
I'm guessing it's more of a hobby for some people. But, I would rather spend my money on the changes!
Anybody else?

quote:To play the devils advocate. Anti freeze in oil, well, if you don't know you have a problem because you keep adding coolant every week then you have larger issues to deal with! Injector problems will also have other outward signs that you should recognize other trhen fuel contamination in a UOA! Abnormal wear, takes multiple UOA with a trend to determine this and in all probability there is absolutely nothing you can do about it and the engine will still last 100,000 plus miles. Extending intervals, yep, valid reason but only vaild if your driving conditions stay the same. If you change jobs, drivers etc. you have to start all over with the UOA to detemine another interval. SO, other then a hobby you make up your own mind!

Might as well burn a $20 bill Unless, of course, the analysis finds anti-freeze in your oil, and you can get it fixed for a whole lot less than an engine replacement. Or you discover fuel contamination because of a bad injector, and get that fixed instead of replacing an engine. Or you find abnormal metal wear, and are able to trace it to a failing component, which can be fixed for $600 instead of replacing an engine for about $4000. Or you are interested in determining if you can extend the oil drain interval, possible saving a couple hundred bucks. Yep, total waste!

quote:Well, I thought that I was in the "overkill" range with a 9.5 quart capacity and dual filters. My first analysis shock (and dimayed) me when it indicated that the oil was all but shot @ 9k. If I hadn't done it ...I would have gone on in blissful ignorace believing that I was doing a great job as the steward of my engine's health. On the other hand ...I think most people on this board are OCI WIMPS!!!! You can count the extended drain (and to many of the membership here exended drain is considered anything over 3k/3m
I guess my point was aimed at extended drain. Why not just save the money and change the oil?
quote:True, and I'm guilty of posting a lot of UOAs on here under 5k. It's a bit ironic when you think about it, but a lot of the reason I haven't done longer OCIs since I begun doing UOAs is simply because I'm so eager to see my next report!
Go ahead ..check the UOAs ...most are 5k or under. That's NOT an extended drain interval by any stretch of the imagination.
quote:That's me.

I use a Brita, I'm safe. I wonder what the flow rating is on the Brita filters??

With Porsche listing 20,000-mile oil-change intervals, I drained at c. 10,000 miles and did an analysis. Next time, I'll analyze at 12,000 without changing the oil. Spending the $10 is indeed saving me money and giving me more info about how my engine and oil are doing.

quote:Last year I replaced my water pump. I had been regularly adding coolant for months until the leak got very bad because my water pump leaked. I knew that. I didn't know if some of it was also going into my oil. In my case, I didn't do analysis, but could reasonably have done so. Besides... how much coolant does it take to mess up your oil ? And how noticeable is the loss ? Probably better to detect it at the "sub-clinical" level before you see it.
Anti freeze in oil, well, if you don't know you have a problem because you keep adding coolant every week then you have larger issues to deal with!
