I should add that (after much deliberation, imagine that) I will also go with M1 0W-20 in my Hondas due to numerous short trips and my impending move to a 'colder' climate.
I realize this basically invalidates my last 37 posts, but for BITOG that is not uncommon.
2006 Toyota Tacoma
2006 Toyota 4 runner
Sl 5w30 ISLAC energy conserving for 5k 6 mo intervals
I will be using Tropartic 5w30 It will be interesting how the two engines will track for me since the Tacoma has a tow package and an oil cooler and the 4 runner does not.
