older motor oil change

I have had several engines that used oil that were helped by this procedure. Change the filter,(you can use a cheep one here) top off with DEXRON transmission fluid, run on highway for about 30 minutes(no hard driving) change oil and filter with good stuff. The dexron dissolves gunk in the engine with out breaking loose any chunks that might plug the oil pickup. If it comes out REALLY nasty you might do it twice. On one of my cars it reduced oil consumption by 25%!!
