from what i can gather most brands high end synthetics all seem the same. (mobil 1, royal purple, pennzoil ultra platinum, castrol whatever it is lol) my guess is you would be fine with motorcraft synthetic i just like trying the supposed new additives and tech in there. For instance pennzoil platinum is made from natural gas and kicks ass in wear tests. mobil 1 has been the stable for many for so many sports cars and is endorsed by most ford dealerships to some extent. heres some of there claims
pennzoil plat
purePlus™ Technology is a revolutionary process that converts natural gas into a 99.5% pure base oil. Combining it with high performance additives means Pennzoil Platinum® Full Synthetic motor oil is proven to keep pistons up to 40% cleaner1 than the toughest industry standard, based on ILSAC GF-5. Additionally, Pennzoil Platinum® keeps pistons up to 8% cleaner than Mobil 1 and up to 17% cleaner than Valvoline® SynPower®.
Mobil 1 basically says its been the stable for 40 years why second guess it .
PROVEN STRENGTH
Castrol EDGE with TITANIUM FST™:
reduces friction by up to 15% * more than the same CASTROL oil without TITANIUM FST™
is up to 45%** stronger than a major competitor, reducing metal-to-metal contact
maintains its strength for at least 140*** hours longer
Royal purple
Royal Purple manufactures high performance lubricants for most automotive, industrial, marine, motorcycle and racing applications. It is considered the best synthetic motor oil by many end users.
Royal Purple synthetic oil and synthetic lubricants are formulated to maximize performance in real-world applications.
Numerous independent parties report performance gains by using Royal Purple lubricants.
Additive technologies, such as Synerlec®, enable Royal Purple synthetic products to outperform leading synthetic and conventional lubricants. These unique chemistries strengthen the base oil for improved performance.
royal purple seems quite focused on performance but thats not really what im thinking about when i choose my oil.
Ive tried mobil 1 and pennzoil ive liked both and i might even give motorcraft synth a try next time if its cheaper.
