If this product's only advantage is to give 5 hp (which "techically" how does it do that?), then I still fail to see the bonus. I have driven vehicles to 250-300K on just dino oil without any problems (2 bucks a quart). Change it every 4K regardless of how I drove it, and it was fine. Once the sythetic trend was in full swing, I jumped on that (4-5 bucks a quart). I can see the advantage of a synthetic that was created out of a flask with the skills of a chemist. There is no dirt of any kind to start with, that has to be better than the dino kind. I have read about many additives like molybdenum disulfide (used on rifle bullets), silicone oils, lithium type greases, and others (6-15 bucks a quart) with very little hard evidence to say "hey I'm better." I'll stick to the Motorcraft products, as I believe that this truck will go 200-300K with regular changes and good general maintainance.Originally Posted by ONE04FX4
i dont believe that mentioned gas mileage in there. as for marketing. no. as for results that i have seen and experienced. yes. sure everyone can throw a bearing in a press and prove there;s is better. but i am going by my own experiences and those close to me which i have seen for myself. it's mine!! i have seen royal purple add at least 5 hp to a vehicle when all oils are used in all places. seen it and done it. not saying that 5 hp is a lot. but i believe firmly in the make up of it and how it works. yes regular oils will work. but i believe that oils such as royal purple and mobil one work better. i think it is a little funny that someone can and will spend thousands of dollars on a truck or vehicle to make it there own and perform perfect and then skimp on something such as oil saying it is too much. it is the lifeblood of the engine. i will always use royal purple now and forever.
