Where can I purchase this product?

Look at the car's maintenance manual and talk with the garage that did the services. Bring the maintenance up to date and then keep maintaining the thing. Properly maintained these things should run for a very long time.

I have a 2003 Subaru Outback with only 94k miles. I just had the recommended work done. It included changing not only the timing belts (interference engine) but, at my request, all the associated pulleys and tensioners. I also had the water pump changed. It cost over $700 but as I intend to keep the car for another decade I feel the money is well spent.

Any good garage should have the proper diagnostic equipment to see if there might be a problem causing the poor fuel mileage.
Thank you for a well-informed reply.

My customers who want a "tune-up" receive a similar explanation.

Many who complain about poor mileage have never actually calculated their fuel mileage accurately.

A modern car is unlikely to have issues that will cause poor fuel mileage without triggering a "check engine" light.

This car has no plug wires. It has 6 coils directly connected to each spark plug. The spark plugs are a maintenance item about every 100k miles. Unless worn or defective to the point of causing misfire -- which will trigger a "check engine" light -- the car can be expected to run exactly the same after spark plugs are replaced apart from placebo effect.

Asking a shop to perform a "tune-up" will result in one of two things:

From a reputable shop:
Questions as to what you actually expect to accomplish with a "tune-up." Also a review of the car's history to see if any maintenance items are due. This is how it is done at my shop. Some people appreciate this, some people don't. If you were to audit my shop's last 1000 repair orders, it is unlikely you would find a "tune-up" labor operation. We address specific needs and issues.

From a shop only concerned with profit: A list of "tune-up" services that will have only a placebo effect but will be highly profitable.

Have you scientifically calculated MPG? This should be the very first step.

I hope this was helpful.

The fuel filter is not a maintenance according to Acura. The fuel filter is NOT a maintenance item on most if not all modern Honda/Acura products. As the owner of a shop that sees a lot of Honda/Acura cars I am trying to remember the last time one of them needed a fuel filter replacement and am drawing a blank. It could happen if grossly contaminated fuel was put in the tank. I have a vague memory of fuel leakage from a poorly performed fuel filter replacement or with a crappy part.

I'm a big DIY type of guy and would buy a repair/service manual for your vehicle and just go to town inspecting, cleaning and replacing worn components.

You can present a printed list of things like this to a mechanic (I wouldn't just "mention these things" I would print them and present them lest things will get missed - more specifically all the hard to do things will be missed) and have them do the work but buyer beware.. you won't know what's really been done and how well unless you do it yourself (additionally, you pay mechanics per hour and likely will end up with a bill over $1k for parts and labor to do all the things I mentioned).

Items that influence fuel mileage of any vehicle can be found with simple searches online. Hopefully you don't have something bad going on in the vicinity of the cylinders themselves, but that could be the case for sure (and won't be positively affected by the above list of items).

Spark plugs for Acura's are easily changed - $40-$50 bucks and 15 minutes of your time. Suggest you watch a youtube video first and get the right spark plug socket. Also use anti seize on the plugs.

Transmission - Honda's and Acuras need transmission drain and fill's every 30k miles or so. DO NOT FLUSH - service bulletins say a flush will damage these transmissions
