My 2007 Prius has 215,000 miles. I was going to use Liqui Moly Engine Flush.
1. I was going to drain and fill with fresh oil, do the Flush, do a fresh filter and oil change
2. I'm running T6 5w40 due to oil consumption with 5w30
3. For the Flush fill and drain, should I use the 5w40? Or a lighter weight oil? Which one would help clean better?
