paul c Posted February 6, 2004 Share Posted February 6, 2004 I just purchased some Amsoil engine flush. The instruction states that you should rev the engine for 15 to 20 minutes after adding engine flush. I'm curious to know what should I keep the revs at.

Lexusfreak Posted February 7, 2004 Share Posted February 7, 2004 I would let it idle to operating temperature first, then rev it between 1500 & 2000 RPM for 30 seconds or so a couple of times.......let the oil drain out longer than usual to get all the bad stuff out, you should be fine after that.
