Thanks for your help and your suggestions. Have either of you, or others
on the list, used any of the high mileage oils that are now on the
market? If so, what is your opinion of the oil?
I do not think they will make much difference unless they are a heavier
weight. I have 140.000 miles on my pickup and it is burning something less
than one quart every 3000 miles. I use synthetic oil and have since about
5000 miles. The last 17,000 miles were pulling a 7700# trailer about half
the time. I have an oil cooler to hook up but that is all I am going to do
before heading out this year.
