This is my first oil analysis. Valvoline 5w-30 High Mileage Synthetic Blend. Red bottle. Concerned about Sodium and Boron. Filled with Toyota coolant. 195k with the v8. Never had a cooling issue. Pretty much babied the thing with 4-5k oil changes. Radiator, TB and WP just replaced at 190k. The 2UZ-FE isn’t known for HG leaks.
