I just had this conversation yesterday morning at my toyota dealer getting my Highlander’s first 5,000 mile checkup.

Turbo. Towing. NO OIL CHANGE UNTIL 10,000 miles, it uses synthetic oil, they told me.

Service manual doesn’t specify synthetic, SFAICT.

You have a Turbo and you use at for Towing you should follow my recommendations. 100000 miles would be 26 oil changes or about $1200. Your dealer recommendation would save you about $400. No Thank you.
