Who has used youroil.net?
 

My last post on a dirty oil filler cap got me some interesting advice. RoninLB brought youroil.net to my attention, which does oil analyses to determine engine health.

Their website and the description on Rennlist look pretty good. So who has used them and what were your results? I'm very interested in this. But of course, I must vett everything with the Pelican Heads first. Thanks.

My only experience with oil analysis is with marine diesel engines.
There, I've used it against several thousands of operating hours.

One thing to remember about oil analysis as a preventative maintenance tool, is it is more effective the longer you do it. It's just not that useful on a one-shot basis. After several samples, (over a period of time), wear metals will begin to show a definite pattern. Excessive amounts of wear metals will stand out and be noted by the technician. The better analysis labs will help you interpret their findings. Then it's up to you to take remidial action if required.

Suppliers of diesel engines are intimately familiar with the oil analysis labs, and are usually happy to recommend a good one in your area.

Rich...many guys on the rennlist board use Larry T's Oil Analysis then post some wild results. The latest thread was a 3.6 w/leaking fuel injectors that was only diagnosed w/the oil test after making the owner nuts for a while changing all sorts of parts to fix the problem. I learned that the silicone readings in my analysis meant that I'm not sealing the air cleaner properly. I agree w/Doug to establish a routine for oil testing. I think once every 10,000 mi. would be OK, not sure.. I will be taking a big ride soon and want a 3 test pattern to see what happens to the tests/engine response to a cross country ride. I wonder if it will show the difference in using different engine oils. Maybe I'll find out which trany fluid in my 915 shows less wear?? The test is cheap/inexpensive....Ron

The fleet I work for uses the NAFTA.......oop's NAPA 4077 oil anal kit.
Just remember oil must be hot and area around the drain should be clean of dirt etc. Also the sample should be taken at mid drain. Also you will need a series of samples to creat a baseline so you can spot problems.
And you should use the same brand type weight etc.

Yup, I used it, found I had excessive gas in my oil. If you look at the table he has, mine's the '77 with the 3.6. I have another sample sitting here ready to send, just haven't taken the time to package it up.

The kits come with a sample bottle (2 different types), a zip-lock bag to seal the bottle into, a postage-paid box, a small form to complete with the car's data.

I will try them for my next 3 oil changes.

This is just a guess, but I'm starting to think I have some gas in my oil. What's the fix for this?

I don't know much about fuel injection, but would suspect an injector. There is a way to test injectors. I think the fix is easy once you narrow down your problem.
