So yesterday I finally hit 150,000 miles on my odometer and I am pretty pround to say I havent had any major problems yet (Knock on Wood). Is there anything special I should have done when I take it to get my oil changed this weekend besides having my tires rotated and balanced and just a general check up? And I might just be paranoid because of the mileage, but a swear when I was slowing down to the gate today it was making a whistling sound. Now it is driving me bat shit crazy not knowing what it was cause it stopped when I came to a complete stop .
