Regarding cost of synthetic oil , I always get a five quart jug of Mobil One or ocasionally Valvoline Syntetic from Walmart for about $18.00.The Mobil One comes in 5W30,10W30 and 15W50 weigth.I too was on a quest to get "the best" for my bricks but Mobil One does the job superbly in my turbo cars.Costco also has cases of Mobil one,six quarts each for about $22.00 in case there are no Waltmarts around.Regarding Mann filters one can get them on line in trays of ten for about $40.00 shipped.Just search for them.I buy them locally for about $29.00 a tray.Another great oil filter and a bit cheaper is Mahle.Made by the same people who make the pistons and rings Volvo puts in their motors.The Mahle filters are made in Austria.Excellent quality.Unfortunately my parts guy can not always get them .I would not use any kind of motor flush.Let the new oil do it.The first couple of oil changes the oil will be very dark.I ocasionally see Exonn fully synthetic oil for about $3.00 a quart.Just shop around.Now if one goes racing that might justify going for more expensive oils although a lot of local racing mechanics I know use Mobil One or Castrol Synthec with excellent results.
Good luck.George
