I am reading faithfuly in the searchs but am looking for straight simple advice. I just bought an 06 Jeep Wrangler with the 4.0l I6. I want to upgrade to a single oil for all my vehicles for Canada. Older Toyota Pickup 22RE I4 and volvo 240 B23 I4. I am planning large volume high filtration filters (Purolator Pureone) and 5000 mile intervals.
What 0W40 syn would you recommend with the proper amounts of ZDDP. Bulk oils like mixed fleet stuff is fine. I feel 40 weight hot is ok for my engines and 0W is needed for 4-5 months per year, real cold starts are often required by me (block heater assist not available all the time).
