Mobil 1 has been the best motor oil out there for many years -- and the new "Extended Performance" formula has made it even better! Walmart's price on the 5-Quart jug makes this an outstanding value on this hard-to-find, top-quality engine lubricant.
Exceptional performance is demonstrated by the oil's ability to maintain it's viscosity under the high tempertures and loads associated with mountainous driving and/or desert crossings.
My Mercury Grand Marquis restoration project has over 120,000 miles on the clock, and with the 5-W-20 Mobil E.P. formula in the engine, the fuel mileage has been outstanding for an American V-8, while the oil pressures and the oil consumption rates are outstanding, as well.
I've found that changing the Oil Filter every 5,000 miles and changing the oil once-a-year (regardless of miles traveled) is the best and most economical oil change program for my driving conditions -- which include city traffic, mountain touring, and trans-desert juants between Phoenix and Southern California.
The Wal-Mart PRICE on the 5-Quart jug makes this the deal that can't be beat !!
