Fuel Additives Revisited

[cessna]

I've been adding Standadyne Lubricity Formula to my fuel. My mpg went up about .7 mpg after starting to use it. I've been using about 2.1 oze per 15 gallons.

I also have Power Service that I haven't used yet. Is there a problem with using both or would this not be recommended? If both were used would the quantity of each be split in half?

Regards,

There are additives that actually do both.(prevent jelling & improve lubricity) The co. I work for buys a product called FPPF Fuel Power plus lubricity. It works well & is compatible w/ '08 vehicles requiring low sulpher fuels as well as older diesel vehicles.
