Never, ever had one done on any vehicle ever I've owned. Thus, I'm ignorant on how to "really" read one.
Numbers look OK in some cases... but causing (unnecessarily) some grief because a few numbers look "out there".
1998 Boxster
Oil Type Grade 0/40.
Oil Use Interval 4,000 miles
Their comment:
Universal averages give you an idea of how these engines normally look with about 4,300 miles on the oil. This run was close to that interval and wear metals are all close to average. That's how a healthy engine looks in testing, and this 98 Boxster seems to be getting along well at 118,300 miles. We're guessing (hoping) 9.3 quarts is the sump size, not top-off oil needed between changes. That would be an alarming amount of oil use, and more than enough to dilute spectral results. The oil is in good condition, with a normal viscosity and no harmful contamination.
Is their comment unusual?
I welcome our seasoned pros give the attached a once over and share with me your wisdom.
Thank you.
