I do my own oil changes... Prius, pickup (both mine), and an SUV, as well as all the lawn equipment... I have blown several riding lawn mower engines... one explosion was loud enough I was sure I died... Bad enough where the scrapper from Craigslist asked if I used it as target practice.
Not once had I considered getting the oil, for any of the vehicles analyzed, or for that matter known it was a thing. Looking forward to the results.
Analyzing used engine oil.
Got the results back. All the readings were within spec. The oil was a little thicker than the 5W-20 that I put in, but that’s due to the STP I added. This time I put in 5W-30, & no STP. The results showed no fuel, coolant, or other garbage in the oil. The car used 16 oz of oil in the 3800 miles. Some new cars use more. Nice to know. GARY.

I've been using Blackstone for about 6 years. No problems with them and very happy with their work.
