Sorry to revive an old thread, but before posting my next UOAs I wanted to ask how best to handle the organization of it all. 1.) Post them here and continue the thread 2.) Create a new thread with all the latest specs and UOAs A.) Link back to this thread in the new one...

Curious why you like the 2.0 over the 2.5, are they more long-lived? Easier on the oil? I’ve never read up on the differences—I assumed the displacement difference was all stroke; if so, more side loads on the pistons? Any info you can share would be cool. Thanks! @The Critic, I’m considering...

I told my wife about BITOG and that you told me to quit telling her to gently accelerate 😂(y) and she got a kick out of it. She told me I'm outnumbered now and she can do whatever she wants! Truthfully, it was always just a delicate request, but we laughed and rolled our eyes about by pickiness...

Thanks for all the info, I appreciate it. That was going to be one of my next questions in here; what would be a good alternative (and hopefully and improvement) for our use case oil and weight that we could jump to for our CX-5?

That's good to know, I'd not considered the accuracy of their tests--yikes, so it could be much worse? Is there another value in the BlackStone test that I can use to verify that the oil isn't too diluted and still has its properties alongside the FP? The first OCI was a lot more city/in-town...

Thanks for the info, sorry, still learning all about this. Any chance you can elaborate on that? Are you referring to the varying levels measured in the UOAs? I just assumed it was because of the OCI and/or the durations the oil was in the sump, but I'd love to know more. The first UOA I believe...

Thanks for the info, I appreciate it. I ended up starting to do UOAs after reading here on BITOG for years and when the Mazda crossed 60,000 miles I started to wonder if the Mazda Moly oil was the best tool for the job. When we bought the car back in early 2015 people were really high on the...

It's interesting you say that. I absolutely do, but on this OCI it was the first time I got some first-start rattle and it startled me. It's never done that so it disappointed me. Maybe I didn't fill the oil filter with enough oil? I know the oil filter initially appears full, but then absorbs...

Thank you all, learned something new. Never thought to send a VOA along with the UOI, brilliant! Also just assumed that the oils were perfectly consistent from bottle or batch to the next...I can now see that wasn't a safe assumption. In fact, kinda feel foolish now, ha ha. Maybe I'll do a VOA...

Sorry, All! 🤦‍♂️, forgot to include the UOI! Doh! Post edited!

Longtime lurker/studier of BITOG and as a result, started doing UOAs on our family’s vehicles about a year or so ago. Reason I’m reaching out is for some guidance/info on the recent UOA on our 2016 Mazda CX-5 with the 2.5L NA Skyactiv motor that we’ve owned since new and that has roughly 77,000...
