Product Description

Rejuvenate Your Fuel System
If your car is running a little sluggish, our 3M™ Fuel System Tune Up Kit might be just the answer for restoring its performance. This kit is a 3-part automotive service kit intended for use on 4-cycle gasoline internal combustion engines. Individual components of the kit include: 3M™ Intake System Cleaner 08954, 3M™ Throttle Plate and Carb Cleaner 08989 and 3M™ Complete Fuel System Cleaner 08813.

Remove the Residue that Robs Your Vehicle of its Performance
This kit cleans the soot and carbon from your engine in three easy steps. It will clean fuel injectors, intake manifolds, valves and the combustion chamber. By doing so, it helps restore power, performance and fuel economy, as well as protects against carbon buildup and engine knocks caused by carbon deposits. Here's how to use the kit:

Step 1: Spray the Intake Cleaner into the engine. This product cleans deposits from the intake manifold, intake valves and combustion chambers of your engine.

Step 2: Clean the throttle plate. Apply 3M™ Throttle Plate Cleaner to both front and back sides of the throttle plate and surrounding areas. A clean rag can be used to help remove softened deposits. Spray and wipe until clean. Most throttle plates can be cleaned with an ounce or two of cleaner. Throttle plate cleaner will both clean and lubricate the system. This cleaner has a lubricant that will keep the throttle plate moving freely until the next time the service is performed.

Step 3: Pour in tank additive. Add the 3M™ Complete Fuel System cleaner to a full tank of gasoline (12 to 20 gallons). Recommended dilution ratio is one ounce additive per gallon. This fuel tank additive continues the cleaning process in all critical engine areas, including the fuel injectors, while you use your next tank of gas.

Appropriate for Professional and Home Automotive Shops
Using this kit is appropriate for both professional and home garage mechanics who can confidently do the following: Users must be able to find the throttle body, open the throttle plate and set the idle. Completing this projects only requires common tools, including appropriate safety equipment, straight and Phillips screwdrivers, a socket set and rags. An instructional DVD is included with the kit.

Make it a Part of Regular Vehicle Maintenance
By removing carbon and varnish deposits, the kit is intended to boost performance for quicker acceleration on the road and increased fuel economy. 3M™ Fuel System Tune Up Kit is recommended as part of a regular vehicle maintenance schedule to be performed every 10,000 miles.

The 3M Fuel System Tune-up Kit is a economical solution for achieving professional mechanic grade fuel efficiency and performance out of fuel systems. Made up of three quality 3M automotive products -- 3M Intake System Cleaner, 3M Throttle Plate and Carb Cleaner and 3M Complete Fuel System Cleaner -- together they work to remove carbon, varnishes at soot from all areas of your fuel system. This easy to use tuning system is useable by virtually any would-be mechanic.

Increase Fuel Economy, Power and Acceleration

Because no engine is 100% efficient, carbon, resins, and varnishes eventually build up in critical engine components, causing a reduction in fuel economy, power and acceleration. Until now car owners needed to pay for a professional fuel system service to remedy this, which can be very costly. But now 3M has provided do-it-yourself consumers with a great new way to get maximum performance from their vehicles from the convenience of their own home garage, for less than ½ the cost of what they would pay for the same results at a service center, with the 3M Fuel System Tune-up Kit.

DIY Solution in 3 Easy Steps

The 3M Fuel System Tune-up Kit combines the strengths of three quality 3M automotive maintenance products into a single fuel system tune-up program that when performed annually, or every 10,000 miles, will improve vehicle performance and gas mileage. These three products are: 3M Intake System Cleaner, 3M Throttle Plate and Carb Cleaner and 3M Complete Fuel System Cleaner. The steps involved in this process are easy to perform and can feasibly be done by a single person, but are more easily achieved with the aid of an assistant behind the wheel at certain stages.

  • Step 1 - 3M Intake System Cleaner: Follow the fresh intake hose to the outside of your engine's throttle body. Remove the hose boot clamp where it enters the throttle body with a screw driver to access the throttle plate. Insert the 3M Intake System Cleaner's attached hose past the throttle plate and slip the intake hose boot back on. With the help of an assistant, start the car engine while the work area is monitored. When the engine idle reaches 500-1,000 RPM, hold steady at this rate and spray the product's contents into the running engine. This process cleans intake manifolds, valves and combustion chambers. Use the entire can, which may take several minutes. Turn off the engine, remove the product hose and proceed to step 2.
  • Step 2 - 3M Throttle Plate and Carb Cleaner: Again, with the help of an assistant, place the vehicle ignition in the "Run" position, but with the engine NOT started, and depress the accelerator to expose both sides of the throttle plate. Spray both sides of the plate, as well as the throttle body with 3M Throttle Plate and Carb Cleaner. Wipe excessive cleaner away and/or let wet areas dry for a few minutes with the throttle plate open before you replace the fresh air hose boot, tighten it up. This process cleans your engine's throttle plate and lubricates key pivot areas. Proceed to step 3.
  • Step 3 - 3M Complete Fuel System Cleaner: This last step continues the treatment of all critical fuel system components. Add 3M Complete Fuel System Cleaner to a full tank, at a recommended delusion ratio of one ounce of additive to each gallon of fuel. Start the engine, allowing it to idle for a few minutes before driving it for 10-15 minutes. 3M Complete Fuel System Cleaner cleans injectors, intake valves and an combustion chambers while your engine consumes this tank of gas.

I purchased this product from amazon for $36 minus the $10 rebate, $26

In general this is a GOOD product. I used this product on a 2001 Acura 3.2cl with about 115k miles on it. Overall, my car did see a slight improvement. Upon inspecting my throttle body it was evident that the intake system was fairly clean, the throttle plate was showing brass color upon beginning. Even though my car was clean to start, there was a noted improvement in the initial startup and idle.

My vehicle used to suffer from a slightly sticky throttle plate and as a result the first time it turns over usually had a bit too much gas, I could feel the engine moving on the motor mounts. Now when I start up the car, the initial turn over is smooth as the pressure required to open the throttle plate is less.

Pros: Cheap, easy to use, does what its supposed to!

Cons: The instructions for this product are really bad. Mine did NOT come with the DVD as it was supposed to. Luckily I watched it on amazon, its posted on the product page. Please note: the DVD is pretty much useless anyway, there is a much better way to do the cleaning, read "other thoughts". I minused ONE star for the missing DVD.

Other thoughts: I found many of the customer reviews to be very helpful!

1) Be aware, many newer vehicles have plastic covers on the engine, most require METRIC ratchet sets to remove, I had to buy a set for about $20. In most cases you cannot reach the throttle body until you remove the covers!

2) Prior to doing Step 1; Park your car at an angle where your throttle body opening is facing slightly downward. You can do this by placing the car on a curb, or slanted driveway.

The 3M DIY Tune-up kit worked as described. I just used it on my wife's 96' Saturn SL1 because I was suspecting misfires when climbing hills. My scanner didn't turn up any codes, but something was definitely wrong. The last few mechanics have all recommended a fuel system service so I wanted to give this a try first. I was quoted $119 from a mechanic to do a similar type service and $220 to perform the chemical injector cleaning that feeds directly into the fuel rail. Don't believe I will be needing that service now because the hesitation is gone.

You may notice that the car won't start after spraying the throttle plate cleaner. I suppose I should have tried harder to clean up the pool of dirty fluid off the the bottom of the throttle body. Next time I will park half the car on the curb to help it drain out on its own. Easy to use - I only needed pliers to take off the intake and some scissors to trim the intake system cleaner tube oh and a brick to keep the accelerator steady.

My car has 100,000 miles on it, and though I've been regular with the required maintenance, I hadn't yet gotten the fuel system cleaned or done anything with my intake system. Last night we did this cleaning system and despite some minor hiccups, it worked just great, and I could immediately tell a difference in performance (whether or not that translates into better fuel economy is yet to be determined.)

The first step is cleaning your throttle plate - I did this, but was alarmed when the engine didn't want to turn over to begin step two. Stomping on the accelerator cleared up all the fluid I had sprayed in there and we got down to business.
The process of the engine cleaner (The one with the long pipe) took us about 15 minutes and is the most annoying part - you have to sit in the car with your foot half on the accelerator the whole time. Don't be alarmed if all the liquid doesn't end up in the engine either, we had quite a bit pool under the car when we were done, but not enough to indicate a serious issue.
The final step is something I should probably use more often (the bottle suggests every 5000 miles) and is just octane booster / fuel injector cleaner.

All in all, it took me about 30 minutes to perform this maintenance, and considerably less money than a dealership would've wanted to charge. On a quick tool around the block afterwards I noticed a distinct difference from before and after.

I drive a manual transmission, and I'm pretty overzealous with my shifting. There's a particular corner in my subdivision that, if taken at too high a gear, always produces the pinging stutter-y engine performance. However, this time when I rounded the corner and shifted into 3rd, the car actually WENT. Obviously, it can breathe easier and was able to compensate for the different gear ratio. This is a nice change and proves that SOMETHING has improved.
All good in my book.

I tried this on my 2001 Honda Civic with 165,000 miles on it. Step 1 may be a bit scary but it seems to work fine as soon as you find a REV for your engine to digest the fluid. On the video it says around 1000 RPM however I had to push to 2500 RPM in order to not have the engine staling. YMMV though.

Second step is to clean the throttle body. I didn't spray directly in it and use a cloth to clean it up however it was pretty clean already so I didn't have to use much of the tin.

Third step is by far the easiest as you just have to pour the Techtron bottle inside the fuel tank.

If I have to do it again, I would do step 2 first before step 1. Why? When your engine has been running for 15 min or so, it gets really hot inside and it makes it hard to clean the throttle without getting burn here and there. Might as well doing it while cold OR wait an hour until the engine cools off completely.

After 500 miles or so after the cleanup, I have noticed the engine to be smoother and not as loud than usual. MPG nor power didn't increase or is not noticeable.

Overall I believe it is a good product and saves you money rather than having to deal with the garage to do it (they charge $89 in AZ) and I will probably do it again in a few years.
