    We have a 1990 Subaru Loyale 1.8 liter with push button four wheel drive with 207,000 miles. I have been using Penzoil High Mileage 5w-30. I've reduced the oil leaks to the point that I do not see any visible leaks beneath the engine on the ground. This I have done simply by replacing the valve cover gaskets, and 'breather' tubes atop the valve cover gaskets. The oil consumption is about one quart every 2,000 miles or so. Though I did not replace the oil pan gasket I did tighten as many of the bolts I could comfortable reach. I have recently been advised by an Amsoil rep. to perform an engine flush using their Engine and Transmission Flush and then use the Amsoil OE 10W-30, and a WIX filter. After 3,000 miles repeat the process. A mechanic at a local shop advised against that because of the molecule size of the Amsoil product, they are all the same(smaller???) as compared with the Penzoil. The result would be more leaks. Any thoughts/experience folks have to offer?
