High Mileage oil - Not yet

Just throwing this out there that none of the 3rd gen (2022/2023) Tundra owners should be using high mileage full synthetic oils. Once we get to 100K (probably 150K for Toyotas) we can then consider using high mileage oils. Most of your probably already know this but a few of our Tundra friends might be thinking that the high milage oil offer better protection. The reason we don't use high mileage oil is because it causes the valve and other seals to swell making them seal better after 100 K of wear. Putting this oil in a newer vehicle will cause the seals to swell pre-maturely and can cause premature wear. Use normal 0-20 full synthetic oil and change regally. Hope this is helpful to someone our Tundra friends. Kid
