i put one on and have not noticed any real improvement in fuel economy BUT I pull a step deck and my loads change all the time so it's harder to notice then on a van or refer trailer. However I did notice that the truck was running better. Even if you don't see an immediate change in you fuel economy I think its a good investment since you will not have to replace paper filters. Plus its a bit of common sense, and it's a fact that this type of filter technology improves air flow.

I don't know that I noticed much if any at all gain in MPG, but I did notice gain in power. Plus at $50 every 3 months for paper filters the Fleet Air will pay for itself.

Will definately help high HP underhood single air cleaner Aero trucks to remove restriction of paper filter that is underdesigned. Mine picked up my 98 Volvo 770 with 500+ hp Cat motor around 3/10ths mpg.

Paid for itself in fuel savings the first month I had it installed over a year ago. I clean mine every 3 months with mostly interstate driving.

I installed the fleet air filter in November of 2010 so since I put it on in winter I don't know if it increased my fuel mileage. I can tell you though that it increased my boost therefore increasing horsepower. Bruce from Pittsburgh power says for every 1 lb of boost you increase horsepower 15 to 20 so being conservative I increased 3 to 4 lbs of boost so that translates to 45 to 60 HP if you figure at 15 HP per lb of boost. Also not long after I installed it I got algae and didn't find that out until Dec 2011. Now since my algae is gone my fuel mileage has come up. My 30 day is 8.3 which is up 7/10th from my average of 7.6. I also installed the FASS so some of the fuel mileage had to come from that too.Fleet air filter said most of the trucks like mine increased 4/10ths but since my fuel mileage was already high I should at least see 2/10ths. I have an FLD 120 with a Detroit.

If you want a filter that will filter better while providing better air flow resulting in performance and fuel mileage gains then yes! No mileage restrictions, and as long as you maintain it, a lifetime filter.

Fleet has taken care of my issue, sent me a new redesign, and the old one has been returned. I recommend Fleet for anyone who runs dusty conditions, or will keep their equipment for a long time. Its a much better way to filter

Fleet Air Filter has been the highest increase in fuel mileage of all the modifications that have been done to the tractor. I HIGHLY recommend that you switch over to the Fleet Air Filters. My Operation is reefer from Midwest to Southeast.

I purchased one on 11/28/12 and took it off 12/06/12 and sent it back. The first thing I noticed was my turbo whistle was audible all the time, meaning it was constantly dilivering boost at a minimum of 12 psi. I called fleet air and double checked the installation making sure I didn't miss anything and i had installed it correctly. I ran with it in from Walcott,IA>Seattle,WA>Phoenix,AZ>Dallas,TX, my average went from 7.21mpg down to 5.94mpg on an average load of 20,000 lbs. In Dallas I pulled into the Volvo dealership and got on OEM filter. Straight away my turbo whistle went away and the psi dropped down to 3.8 on a flat. Mpg went back to pre fleet air levels. My truck is an 07 Volvo 780 with the D12, now perhaps there is a design flaw with the filter for my particular truck or I may of got a bad filter, as I now others have reported semi positive results. I purchased the filter from the Iowa80 truck stop and they have a 30 day return policy so getting my money back was not an issue.

I've been running one for a year now and have seen no difference in MPG and no difference in power and as far as cleaner the oil sampler still has the same amount of silicon in the oil . I wouldn't spend the money to purchase another one.

What about the fact that you can wash the Fleet Air? You don't have buy a paper filter every 3 months.

by

That's fine that you can clean it but for what I paid for the filter I could buy a lot of paper filters to be exact 12 of them so you figure it's going to take about 6 years providing you were to change the paper filter twice a year

by

I've been do some testing while truck was on dyno there's no improvement in power what so ever with fleet air filter vs plain oem filter power output the same and the fact that fleet air filter say's there filter should be cleaned between 20,000 and 50,000 that means you could be needing to clean it ever 2 months.

by

Have also found that the OEM paper filter is keeping out the dirt in the oil 30% better. Always have run 8 & 9 parts per million with fleet air filter with OEM filter it's at 5 parts per million .

I got one and noticed slightly better performance. Should've gotten a K&N though - no oily mess.

K & N doesn't use oil but its only guaranteed for 350,000 miles. The oil on the Fleet air filter lets the filter breathe better and traps the dirt. The K & N is more restrictive. You bought the better filter, yes the oil can get messy if you use too much oil. I did that once. Just took longer to clean is all.

Didn't notice any mpg or performance gains, but my loads change all the time. The oiled foam is a far superior filter media compared to paper.

WARNING: I have a T600, and had a construction issue with my first Fleet. I had unfiltered air going into my engine.

Fleet redesigned the T6 filter, and sent a replacement. They handled it well, just beware of sealing that could lead to unfiltered air entering your engine.

Update

Interstate 5, I will post pics asap of my original filter. While i am happy that Fleet is taking care of those who call, why is it up to the consumer who put faith in a company to do proper engineering? Why aren't they calling US, or having Kevin alert us during the show? Frustrating.

Can you elaborate on the old design? My friend has a T-800 and he has one of the older Fleet Air Filters (he bought his about 2 years ago). I have an FLD 120 and both our trucks take the same filter but I bought mine only about 6 months ago and there is a noticeable design change. I wonder if my friend has one of the ones you mentioned that is letting dirty air get in the engine?

by

I5 trucker. Which filter do you have? I am on my 3rd different filter. They keep tweaking it. I also have an fld 120. None of mine ever let dirt into the engine though. The first one had a problem with the gasket, the second one had a removeable bracket on the end, and now the 3 rd one is all one piece with a lip on the end to keep it in place and a whole different style gasket.

by

Jackie, I have the 3rd one you mentioned, but my friend with the KW T-800 has one that looks like it was "home-made" from a Fleet Guard Paper Filter. He is not to happy with paying so much and then when he got it, it is obviously made from another companies parts. He bought his a couple years ago.

by

Yeah the first ones were like that. He needs to call Fleet air filter. They will fix him up.

by

Thanks Jackie, I will tell him tomorrow.

A fleet air filter is one of the things I am planning on doing to my 2010 T660 with a Cummins 455 ISX. Just had Airtabs put on last week.

We are working on that filter currently. If you have ever pulled that filter out you would see why. We are working on designing a new housing that will benefit your truck more.

the reason the gasket kept coming off is because of vibration and movement of the filter frame. the latest have a larger flange at the inlet side, which keeps the filter from bouncing around

Yeah mine has that also, but the first gasket didn't stand up to the heat either which made it easier to slide around and come unglued. After I super glued the gasket it never came off in that spot again.

Give me a call today and I will get you a replacement sent out. Easy as that.

That will be a future issue. It will have to be a entire housing made not just a filter.

In my opinion, the MPG gains come from the engine not having to work as hard to move the same load. Two weeks ago, I installed them (and the performance muffler) on a Western Star car hauler with a 14L EGR Detroit. It seems to require 5-10 lbs less boost to move the same loads over the same roads at the same speeds. Boost made to fuel required is not a linear relationship; it is slightly exponential. Let your boost gauge influence your right foot after you make your purchase and installation; you will definately see results.

I love this filter not sure about Hp Or mpg my truck is all over the place but my soot went from 1.8 to .6 i have less soot less metal in my oil samples too. Here is Another great advantage if you happen to be driving and a dump truck kicks up so much dust you cand even see the road which then gets sucked into your air filter you can clean it the next day clean as often as you see fit for you particular driving circumstances. It's save money period.

We put one on our truck in Feb of 2014 . Seemed to help both with HP and a bit with MPG at first doing long haul, but now doing shorter hauls, (same milage each week) we seem to be loosing our MPG. We are going to switch back to the paper filter to see if that improves it.... will let you know.

I'm always highly suspicious of such claims. Quite simply, if a differently designed filter improved power or efficiency even a small fraction of a percent, all manufacturers would use it on their engines -- it wouldn't be an aftermarket item.

And assessing MPG changes is very difficult, if even possible. Even when pulling a van, small changes in which way the wind is blowing and how fast, has a huge effect on MPG's. And even that presumes hauling a load with the exact same weight over the same route in the same direction and the same number of stops/slowdowns, same number of goofballs cutting you off, same driving style over every hill, etc.

Some engineers should do testing on various tractors and technologies. Surprised there isn't such an organization and publication, given how important every 1/10th of a MPG is to truckers.

I had a Fleet-Air filter in my T600 with a 2003 ISX (the good one- pre egr!) I had it on for approximately 5 months (cleaned and oiled regularly) and noticed zero mpg or power improvements. The only change at all was immediate increased silicate levels in my oil samples. Sold the truck with it still installed.
