I bought the truck brand new in 2005. I have been using Mobil 1 synthetic oil ever since. I took the valve cover off at 150,000 miles to see wear, and expected to see some type of oil degradation. But I was surprised, it looked factory new. Not even varnish! I was extremely pleased.
Mobil 1 synthetic oil is No. 1 in my book. Not many people can take a high mileage engine and find the top end to look brand spanking new!
