Pro
I am using it now for the second gas fill up and notice a significant change in gas saving and power. I guess it does the upper cylinder cleaning as it states on the label.
Con
I get 32+ without additives. There is no science behind it. I do not use additives of any kind anywhere on my vehicles. Best thing for mileage is proper tuned car, proper tire inflation, and gas pedal control.
Lucas Oil Fuel Treatment Specifically, Fuel Additives Generally
micah861 » I’m not sure at all why everyone is so upset about this. personally i began using the occasional additive after i got the car from my father. i also added a k&n filter (which i maintain frequently) put mobil one oil in and do other frequent maintenance. i attribute a little bit of my good mileage (32 highway, peeking at 34) to these things. Now during the winter my millage drops horribly, and i also blame part of this to station additives. I was taught in school (agree or dont) that station have more ethanol added during winter to help absorb water condensation in the fuel and prevent ice. ethanol is not as efficient as gas so millage goes down. I also idle a lot more during the winter but thats my own fault.
I don’t know the altitudes where you all live, but i was also told a theory that us at higher altitudes (i’m over 6000 ft.) have less power but get better mileage. Our engines detect their being less air, and therefore inject less fuel to keep the o2 sensor happy. i don’t know if that’s true or not,but i know when i drove to texas over the summer, i had more power down noticeable more power down there.
instarx » You are right, Matthew, it is mostly a personal issue.
Personally whenever I go to a parts store and see all the claims on packaging saying Improves Mileage! More Power! etc. I feel like I’m being jerked around by the companies’ PR* departments and I don’t like it.
We do have evidence that 99% of these things don’t work, but it is indirect evidence. If any of the products (additives, expensive air filters, vortex generators, etc) gave any meaningful improvement in MPG the companies would be shouting the test results to prove it, and they don’t. An exception to this general rule are the new mpg-improving synthetic oils, and guess what – they DO give test results.
Many of these companies count on the cognitive dissonance in their customers’ brains to convince them their cars run better with these products. Cognitive dissonance is a powerful force – heck, my brain knows for a fact that my engine runs smoother when I change the antifreeze! I once had my engine cleaned so that it looked like new under the hood – man that thing ran sweet afterwards!
