I agree. The better and more expensive the oil and the vehicle, the more important it is to leave the oil alone! I should know, I've ruined engines in a Mercedes and in a Toyota many years ago by using something called TufOil with Teflon. The characteristic of one aspect of the oil could be enhanced but it happens at the expense of other valuable oil characteristics. If you use conventional oil or don't plan to keep the vehicle, have a blast. Again, using a combination of the best oil and the best filters are the keys to a long-life vehicle. Keep us posted.
