Bought my wife a 2017 RAV 4 and I am getting to the age where I am going to be completely hands off. All maintenance will be done at the dealer. That being said, first oil change is suppose to be at 10,000 miles, or one year ! My "oil disease" makes me shake and sweat, can it go one year or 10 k on factory fill? I am assuming they use synthetic , as manual calls for 0w20???
