If I'm switching to synth. oil, do I need to Engine flush an engine with just 23,600 miles? The oil is very clean, and my current feeling is that it's not necessary. Some AMSOIL dealers claim 50,000 miles or more, while others claim 15,000, and still others claim the miles don't matter. The car is only 1 1/2 years old. It was previously maintained under warranty, so I'm certain is has had it's regularly scheduled oil changes.
Thanks.
Joe
