This is the first time Amsoil has been in the Civic. I think it did pretty good, compared to the previous 10k run with Mobil 1 EP 5w30.
Engine oil capacity:
4.0 quarts
Oil filter:
Amsoil Ea15k13
Air filter:
NAPA Gold OEM replacement (10k old at the start of this OCI)
Make up oil added: 1/4 quart at 7k just to top it off before a long trip.
USE: 50/50 Highway/city - with plenty of short trips (10 miles max)
Drove 3,000 miles within 2 weeks prior to this sample.
~Refilled with the same package for a second run. (i expect to see better results with a better concentration of SSO)
Does anyone else think the TAN is a bit high? (meaning Acidic.) In one of my other reports, Blackstone commented that a TAN of 2.2 was showing acidity present. ?????
