Newby here. Just added a 2019 4Runner Limited to my stable. Already own a 2015 Tacoma. I have a question about maintenance. The 4Runner has the same 4 liter as my Taco but it uses 0-20W versus 5-30W for my Taco. After reading the maintenance manual for the 4Runner it appears the oil change interval is 10K miles vs 5K for my Taco. Would someone please confirm this is the case. Also in my Taco it was recommended that the nickel spark plugs be changed at 30K. I went with Irridium in my Taco. Does anyone know if standard nickel plugs are used in the 4Runner? Thx for any education you can impart on this old timer.
