I'm getting ready to change the oil in my gassers. I remember sending my oil samples to a lab in Arizona the gave me a great report and kept track of any wear. But I can't find their name in my notes. (It's a bitch to get old!)
Does any one have a lab they can recommend?

I've used Blackstone.

+1 on Blackstone. I especially like their comments section and on the occasion that I called for clarification they took the time to go back through the file and the data with me.

My 2 cents on oil analysis.... As a stand alone tool- one time or new analysis is next to worthless. Comparing a benchmark to results of future or previous tests, they have increased value.

Lab rats try to read the tea leafs and comment on longevity and use of the engine with poor success.

A few friends in work boat maintenance have told me different engines they have in their stable have drastically different results in sodium and aluminum on some engines, but never concern them selfs with levels unless something changes.

So it may be worth your time to search a little deeper for your old results or lab, if they kept test on record.

Information and data is great.......but if it doesn't translate into a positive coarse of action, it's value is questionable.

Just my 2cents...... Other people obviously swear by them.

Absolutely true!!! Certain things may be deducted from a single test... Other things require seeing long term results as it's not the value itself that's important but rather the trend of the value...

thanks for all the information here. I agree that long term trend analysis are the real worth of these test, but we have to start somewhere. I'll give Blackstone a try.

It would be well worth your effort to try and track down your previous lab... They should have your previous results on file...

Sent the 2 oil and 2 transmission samples to Blackstone on Friday. We'll see how they come back.
