I was reading some information recently on some additives such as PS "Diesel Kleen" and Lucas Oil Products. They each claim to protect from excess wear but ALSO increasing miles per gallon. Anyone use them? Anyone tried them? Any thoughts or opinions on these would be appreciated.

 

CNN just did a segment on all those devices. They actually had a shop with a dyno and a test car under controlled circumstances and not a single product boosted mileage. In fact, every single one decreased a persons mileage.

Lets put it another way. If there was such a product for cars or trucks you would NOT have to advertise it. It would be on every news channel coast to coast.

 

The only time I use additives is in the winter, to prevent gelling. When I use additives, I use Howe's.

As far as improving fuel mileage, I have my doubts, but there are some who swear by it.

The best thing for saving fuel is to lay off the gas pedal. Plain and simple.

 

Like Rev. says Anti-Gel in the winter is pretty much a must in the North country.
Lucas is a very good product

 

Last November when I parked the truck for a month, I filled up both tanks to the top, and added two gallons of Howe's to each tank (one gallon is supposed to be good for 300 gallons of fuel) :roll:

The darn thing STILL got slushy on me. :evil:

 

all the years I've driven I only froze up once and I never want that to happen again-what a Pain-happened down by you in Oshkosh.

 

For anti-gel, I use the red bottle of 9-1-1 in the last tankful before I shut it down. Get two of the smaller bottles and put one in each tank. Never had any problem, but if I do, I also carry a couple of bottles of "MELT-DOWN".

I think I liked the mechanical injectors better. Used a little anhydrous isopropal alcohol, about a quart in each tank and survived -54 F in Quebec City one time. Don't know what the wind chill was, but it was blowing. There were two of us running then, and the other guy had three pair of wool socks and a plastic bag over his fuel filter.

 

Vassago I'd take that as a hint to change additives. I used Howes one winter and it gelled up over Christmas holidays. Once was enough for me.

 

If the additives worked to increase your mileage, they would be put into the fuel before you bought it. With all of the energy conservation going on now, the fuel would have it added in. If those products were so great, the engine producers would recommend their use as well.

 

I have heard of some who swear that they improve their fuel mileage with Lucas. I think the cost is such that it would need to dramatically improve mileage to make it economical. Keeping up maintenance and watch how you drive will do as much as anything else. You could keep your speed at or below 70 and not constantly speed up and slow down that will help. Keep an eye on air filters can also help. When an air filter gets dirty it can drastically lower fuel mileage. You might be surprised at how much fuel mileage can improve by slowing to 65 mph.
