Wrecker. 200,000 miles. Starting to use a little oil (1/2 quart every 3,000 miles), holds 8 quarts.
It is no wonder your rig is starting to use oil if you believe that it holds 8 quarts; it holds 15 quarts.
They did (and still do) put Gas engines in the Ford F-450. None of Ford's Gas engines hold more than 8 quarts of oil.
These comments are longer than the actual review...
It'd be nice if people chose "gasoline" or "petrol", I was confused for a few moments there. There are plenty of world markets that actually use gas, as in LPG or propane, afterall.
He said right in the review that it's a Diesel.
Also on the "gas" thing, it states clearly that the reviewer's from North America. that should clear it up.
