Is there a diesel fuel additive out there that actually works?
Sick of paying so much for gas asked:
I have been considering spending money to buy a fuel additive to increase my mpg and hopefully as an end result help me save money on gas. I am leery to start buying tablets though as it is an added expense in itself. Does anyone have any experience with diesel fuel additives? If so, can you recommend one that works?
there has been diesel fuel additive about as long as its been for gas burners.. but done will increase mileage but they do help clean the motor which is what they was made for.. changing the air and fuel filters will get you more
I have used diesel fuel additive products from and they have worked really well for me from my use. I really don’t know much about the science behind them, but I can notice a difference at the pump and thats all I care about.
Try Howe’s. If this doesn’t improve your performance after one 1/2 gallon bottle then there may be something wrong with the engine or your driving habits are just too hard for to benefit from a diesel.
Howe’s is sold as an anti-gel but most of the old timers I use it year round. You can’t add too much and it’s a good back up if you gel up in winter. Just pull the fuel filters and pour the gelled fuel out and refill the filters with Howe’s and add the rest to the diesel fuel.
P.S. Something known only to old truckers. NEVER fuel up in Missouri. They water down the fuel (organized crime trick) and every driver I have ever spoken with has gelled up, sometimes right at the pump, from fuel purchased in Missouri.
Good Luck!
ive had too much experience with them.DONT use them.they damage the pumps and the injectors.unless you have a shit load of money in the bank DONT use them.
I work in as a fleet mechanic on International trucks. There is no diesel additive on the market that will increase your fuel mileage. There are plenty of additives out there, but nothing that will improve your fuel mileage. If there was, we would be using them in our fleet.
The only thing we ever put in our fuel is automatic transmission fluid. We put a quart in the fuel about every third tank because it is high detergent and helps keep the nozzles clean.
I am sorry to tell you, the only way to improve your fuel mileage is to change driving habits. This didn’t set well with our drivers either.
Matt, I have also used the diesel fuel additive from and have found it to help. It’s easy to use as well…just drop in the tablet. The other thing I have found is that they help with keep my dogs in line, just kidding. I guess you could say I’m a happy customer of theirs.
