Thanks ThirdYe, Walmart synthetic is cheap and I feel good changing every 5,000miles. Oil changes and such are my escape from my lovely wife and kids. I can make an oil change last all day... she doesn't know any different... hee, hee, hee.
My father in law always over-maintained his vehicles and back in the 70's when no one got over 120,000 miles, his cars and trucks ran like new at 250,000 and more miles.
