What specific engine oil should I use for the life of my vehicle? Should I use the same oil during my break-in period? I just purchased a new 2018 Toyota RAV4 XLE with a 2.5 Liter 2AR-FE engine and automatic transmission. The owner's manual specifies a 4.6 quart capacity of 0W-20 [oil grade ILSAC GF-5] multi grade engine oil. The recommended oil change period is 10,000 miles. The manual also provides the following break-in suggestions during the first 600 miles: - Avoid sudden stops. - Do not tow a trailer. - Do not drive at extreme speeds. - Avoid sudden acceleration. - Do not drive in low gears for long periods. - Do not drive at constant speeds for long periods. I live in Minnesota where the temperature range is quite large (up to 90F in the summer and down to -30F in the winter). My driving habits are mainly defined by my 20 mile (one way) daily drive to work in which ~10 miles is free flowing freeway traffic and ~10 miles is slower city driving with stop lights. I also have occaisional road trips that are 500-700 miles over a weekend. In general, I avoid high acceleration. For many years, I have been using Mobil1 synthetic oil and changing it at ~5000 mile periods (which is about three times per year for me). My logic was based on two ideas: (1) extreme cold weather starting is much easier with synthetic oil, and (2) I want to remove the contaminants from my engine to keep it functioning properly for a long time. I've read comments on RAV4 forums that suggest changing the original factory installed oil after 1000 miles, followed by conventional 0W-20 oil changes at 3000, 5000, and 7000 miles. Afterward they suggest changing to a full synthetic 0W-20.
