guvnaguy Posted November 30, 2016 Share Posted November 30, 2016 Hi, I have a 2.5i with around 90,000 miles but in good driving condition. I recently moved to Anchorage, AK from WV. Prior to the move I had the oil changed to synthetic as I had read it performs better in very cold weather. I keep the car in my garage but at work there is only outdoor parking. Last couple nights it has been 0 - 10 degrees F. When I start it in the cold after work it turns over fine but makes a loud, high-pitched rattle for a split second until I turn the key back; sounds fine after that. Never noticed this in warmer weather and sounds like it would be damaging. Is this maybe from the oil thickening up? Thanks. Link to comment Share on other sites More sharing options...
