Thank you so much for posting. I was on their website yesterday and decided that this will be a top priority for our bus (be great if we can do it before we buy). Might have our race car checked out also.

Tex, could the high iron in the trans be from the drain plug itself? Just a thought. Thanks for posting this info, it is nice to "know" what your oil is doing!

I thought about doing this a while back but just got lazy. I found out about oil analysis from a maintenance foreman many years ago. When dealing with construction equipment, I guess a $50k engine is not uncommon.

BigTex, now you have a base line you can compare future analysis' to.

I use them every other oil change.

25 bucks for a test isn't too bad, but add it to 5 gals. of oil and a filter, or two --ouch!

Better to pay now and avert a rod through the block or spinning a main bearing.

2000 for a bus, 100 for an oil change, 3000 for tires. Bus'n ain't really cheap, is it?

You forgot to add in the high resale value.

Nothing like playing it safe but I think that's excessive. I don't see the benefit of doing it every other oil change.

8000 miles on an oil change. Lots can happen in 16000 miles on a 210000 mile engine. I could go to every 3rd I guess.
