#1 of 4 Lifter Noise
Feb 11, 2010 (12:51 pm)
We purchased our CX-9 in August and have approx. 7800 miles on it. I noticed that when the weather started getting colder the lifters chatter quite a bit for a while when first started up. The oil has been changed twice by the dealer. Is this a problem or should I switch over to synthetic oil?

I have noticed the same noise on our CX-9 that has 3000 miles. I am taking it in this weekend for the first oil change. I will ask them about it and see what they say.

Could it be a sticky valve?
Drop a bottle of Gas Treatment ($1.5 each) on every fill up for a few tanks, and see what happens.
I do that on every other tank of gas.
