I am sitting on a family-gifted case of 10w30 QS Peak Performance and have a 2002 CR-V and 2006 Accord EX, both take 5w20. Where does Peak Performance fit in the QS family, for starters? Is there a Colorado season when it is advisable to run this, or maybe mix a quart with the usual PYB or PP 5w20? Or should I just donate it to a friend?
Thanks in advance.
