Oil analysis tracking app or program?

Blackstone about every 3rd oil change for me. They keep the records and show you the trends but it sounds to me like you are looking for something more extensive @Siinman.

 

Polaris Labs. I use them for coolant analysis. You set up an account and can go and look up previous reports/trends on each piece of equipment you have in their system. They are very good at what they do, and little on the pricey side....but worth it if your a data nerd like me. I use Blackstone for oil sampling and Polaris for coolant sampling

 

I do. I put the hose down the dipstick tube and fill up the bottle. Then I unscrew the bottle and dump it back into the engine. That clears any debris, and also clears the tube of previous oil sample. Then I screw the bottle back on, and take the actual sample.

I use blackstone labs, usually get results within a week of mailing in my sample. The automatically send me additional test kits.

 

Same as him - I use Schaefer's too.

I bought an Amsoil spin on bypass filter setup for about $350 - it has an oil port on it for clean samples.

 

I've only used Cat's SOS as @Oxbow said. I also use their sample gun SOS-PUMP about $27 and a very nice quality product. I've had no issues with sampling from the dipstick. I was sampling about every 10k to find a sweet spot which for me (2015 VNL 780) is about 25k.

The NAPA pump looks just like the CAT pump. CAT for the win at $27
