After following this thread thru, I'm convinced the problem I'm having with start up on my 04 Quest is due to this specific problem...A lack of ester based oil. I have been using MB1 in the 3.5 since after breakin with no problems at all. The last two oil changes I have been using Pennzoil synthetic. And now I'm hearing a slight knock at start up. Sounds like marbles in a can for a second. I wonder if my 08 SpecV requires the same ester oil?
