MC 5w-20, 4000 miles, '06 Mazda MX-5

[AZ Rider]

2006 Mazda MX-5 with Mazdaspeed CAI. Motorcraft 5w-20 and OEM filter. Oil was changed @ 1k, 3k, 6k, and again @ 10k miles. This is the first test.

Car was driven in metro Phoenix during record high temps- 32 days 110 degrees and higher. This was also monsoon season, but little rain and lots of dust.

They say the TBN is 3.9 but in the report it says 3.2, any idea which one is actually correct? Regardless, that oil did great in your Miata, I'd keep using that stuff

Looks great.

I agree with the above. If it works for you and it makes u happy, stick with it. Good luck and good numbers.
