Regardless of the brand of oil used, make sure to use a quality full synthetic. The Mobile 1 you already use in the proper weight will provide good results as long as you change it according to Mobile's recommended service intervals or less. As for
AMSOIL synthetic oil, it offers the longest guaranteed service interval of any oil on the market and has offered that same guaranteed interval since pioneering the market in 1972. If you are in to getting the most value by taking advantage of extended service intervals, AMSOIL will save more money, produce less waste and require less actual labor or labor charges than any other over years of maintenance. If you just want the best possible oil on the market? There are as many different opinions out there on that subject as there are models of vehicles on the road, but I tend to lean toward the oil that can guarantee the longest possible service interval. If their oil can stand still be viable for longer than the others, then it must be able to protect better than the others as well.
As for filtration, the undisputed leader is also AMSOIL
EA Oil Filters, manufactured by Donaldson filtration using an exclusive nano-fiber filter media that filters to an efficiency of 98% at 20 microns, no other oil filter on the market can match it.
