Why would you blend either version of Power Service with Ford additive anyway as they all have cetane additives?

It's pretty easy to think two substances won't interfere with each other, but every year hundreds of people find out you can't mix two common household cleaning agents without producing poison gas. That would be chlorine bleach and ammonia.

Additionally, Ford specifically warns about adding anything to fuel except anti gel and cetane booster. But, what the hell do they know? Lucas, the only seller of lubricants that spend more money on advertising than STP did in the '60s and '70s says add transmission fluid!

Guys are mixing anything and everything into diesel fuel trying to find a magic potion that will increase performance and/or longevity. I have never read any scientifically valid study that shows there is such a potion, but what the heck, Elmo down at the corner garage has a friend who has a cousinthat has a 6.0 with 533.654 miles on it and he got there by mixing a pint of used tranny fluid, 6 ounces of premium gasoline and 2 tablespoons of virgin olive oil (because that weird lady on the Food Network always raves about "V.O.O.") in every tank.
