Hello all! My 2002 ford focus is on a diet of penn platinum 5w20 with a motorcraft filter. Car has 59,000 on it and when I start it when cold I hear some engine noise, not ticking but kind of a light knock. As I accelerate the sound gets louder! As the car warms up it totally goes away! I have tried mobil-1 5w20 and 5w30 and both oils made the cold start noise worse! I would really appreciate any suggestions from all you experts out here!
Thank you so much guys!! Hope all of you are enjoying your weekend!!
