I have an Azera 2009 limited and when I start it up I hear engine noise until the oil is flowing. I brought it into the dealer a few times and they assured me that its normal as it just takes 30 40 secs for the oil to lubricate the chain.

I would like to add an additive to the oil like Lucus or the STP so that the lubricant stays on the chain.

Can I do it without damaging the engine and has any one else have a similar problem?

Also the car has remote start and I was wondering if that races the engine during start up.

 

1. Do not use STP
2. The noise is not normal. The problem is the timing chain tensioner. Have it fixed under warranty.
