I did a search but could not find anything on the oil analysis service that NAPA sells. The kit is $14.50 or so, but does not say if a TBN is included. If you used them, what is the quality of their analysis?
Does anyone have any info on the NAPA used oil analysis. I think it only cost like $14 and you can order it on NAPA online. I wondered what all tests they run and if maybe someone has a test results to post?
I'm kind of curious too.....they have a couple different products available on their site, if you search for "oil analysis" - but no clear description of the difference between the 2-3 different items....though they are different prices.....
