fuel additives

I have used the lucas fuel treatment & have always had positive results. I fill my filter all the way with lucas, when changing my filter & pour the rest ii the tanks at fill up. always noticed better starting & always better m.p.g. I have tried others, but never saw a verifiable improvement like lucas.

 

If you think a few ounces of something dumped into 100+ gallons of fuel will make even the slightest difference you will soon be parted from your cash.

 

when i had my truck i would use diesel clean cetane booster (gray bottle not white) in both tanks on every other fill and it made a good difference especially noticed when at an idle but milage was usually on average half to one mpg better after i started using regularly but every truck is different

 

I do the same thing heavyhauler does when I change my fuel filters. My fuel tanks are always full at the house and when I leave out on that first trip after servicing I always get a couple of tenths better mpg's on that tankful. I don't know if it's just the fresh filters, the lucas, or combination of both but my mpg's always surprisingly check out above normal on that first tankful afterwards. Never do put any of it in the tanks on other fillups though, just on filter changes. Other than that I might dump some Howes in there if the outside ambient temp gets below 10* F but that's probably overkill. I never really had a problem with fuel filters clogging up until I saw temps below -25* F which are temps I rarely see in fact only once in the past 11 years thankfully.

 

I use Lucas once a month and it helps me get better MPG by say 3/10ths...
I believe it helps clean the injectors, and get you better MPG. I just use it to help keep the lines clear and free of debris and gunk from this ULSD

As for Power Service, I have used it a few times and I actually got WORSE MPG but it was also -30* outside so that could have been a issue too. I only use it when i can't get Lucas

 

Save your used motor oil and pour up to a gallon in your fuel tank when you fill up with fuel. There' a chart around somewhere where they took all the common additives and did a full evaluation and comparison with them. IIRC used oil scored right up there with any of them.

edit: Having said that I did a search on the topic and some people say it'll screw up your injectors:

Thats what I use. It goods for the fuel cause it gots that ulsd formula!

 

I use Howes or Lucas regularly.Mileage is where I can tell a difference.Usually 3/10s to half a mile better.Sat down one weekend after a discussion and it worked out that I saved the cost of the additive times two.
