I’ve been told by my dealership newer engines and oil can last for 10k miles……at least til you get to 100k, then 5k intervals, at least for my 2020 RAV4. Mine is in there every 5k and hope to get at least 300k out of it at that pace. Of course, I will put 40-50k miles on it a year.Probably a dumb question but gonna throw it out there. in my 25+ years of driving, I have always be a 3k oil change guy. Was told the new car only needs changes every 5k. Is this true? Not looking to set fire to money but the thought of driving 5k before change gives me indigestion. Is the new synthetic stuff really that good?
