Hmmm, never had that problem yet. I have used synthetic since the first change at 2500.

I will keep an ear on it.

By the way:

I live in the Exton area and I will be living in W.C. starting this weekend. My G.F. and sister are moving into thier house up there and I am sure I will be spending the night up there every weekend to party. Have you ever gone to one of the Scott Honda meets??

Well, I will probably be cruising around up there this weekend, so Keep and eye out for me, I will be on the lookout for you.

I will give you the finger as I drive by so you know its me

Heres my car. I got a TXS turboback so you will hear an exhaust.

it's ok.. it's not about the synthetic.. just coincidence... Jon was nice enough to post the tech bulletin last year informing techs about customer complaints about valve noise in cold weather till the vehicle warms up.

It's just the design.. it will make a little chatter when cold.

My wife is still on dino crude in her car and her's does it. Mine does it with synthetic... but sitting in the garage it doesn't do it anymore.

It's all good.
