Optimize your MPG

Every time you fill your tank, you expect to drive a certain amount of miles on it. An engine that's caked with deposits makes your engine work harder - less efficiently - every mile. So next time use Techron Concentrate Plus to help ensure maximum fuel economy.

Keep it Clean

Fact is, gasoline is a mixture of hydrocarbons including ethanol and other impurities. As it travels through your car's fuel system, harmful carbon deposits can form on critical engine parts. Techron helps remove these deposits, restoring lost power and performance.

What is Techron?

Techron is an additive technology that works to get the most out of your engine thanks to our patented fuel additive technology which is trusted by motorists, mechanics and auto manufacturers the world over. You can use Techron and when you do it will clean your engine, leading to better performance, lower emissions and maximum fuel economy.

What does it do?

Engines are designed to work at their best when they are clean and modern engines are designed to work with finer tolerances and at higher temperatures. Techron works molecule by molecule to prevent deposit formation, and in the case of deposits left behind by low quality gasoline, works to remove those deposits.

How does it work?

Techron is proven to be effective at keeping both modern and older engines clean. The result is maximum power, lower emissions and maximized fuel economy. There have been significant advances in engine design including hybrid and direct injection spark ignition technologies. These engines are designed to work at their best when they are clean. Even microscopic amounts of engine deposits can adversely affect performance.

User questions & answers

Question:	Do people really use this every 3,000 miles? How often do you do it
Answer:	They are both excellent products. I like this one because an older engine really responds (especially if I fill up with premium gasoline). This company has great products. Try one, then a little later try the other. You'll see how your vehicle responds. I just know before a long trip, this stuff is confidence in a bottle. Smooth, peppy, miles to follow.
Question:	it's a real pain to open Techron bottle's seal. do you guys have any tips on opening it easily
Answer:	Most of this information is available by calling 202-282-8000. If they can not answer your questions, they will direct you to the right place.
Question:	I found an old unopened bottle of the original concentrate, not the Plus. Probably 10 years old. Is it still OK to use
Answer:	crc says you need a special export license for the caribbean but us is ok
Question:	Is there any reason why after using this that I should also use Chevron's fuel injector cleaner or does this do the same thing

User questions & answers

Question:	How to use this ? Can I just put this to the fuel tank
Answer:	Dump it in the fuel tank and fill it up with gas. This large can will treat up to 20 Gallons. I use it in my motorcycle, so I just put a small amount in. It also has a fuel stabilizer in it which is good cause I don't ride the bike that often.
Question:	Does this work in small gas engines
Answer:	What do u mean by small gas engines? Im running a 1500cc engine and works well with it. Is this small enough?
Question:	my tank holds 33 gallons, would i have to fill it up only will 20 gallons after i pour in Max Clean or could i fill right up
Answer:	If you have problems with injectors I would use two cans. I would suggest if that does not work get the injectors clean. Check out Scotty Kilmer on you tube or on google he has a professional way to clean injectors. Honda has the most problems after about 130,000 miles and should be clean. I know because I own several.
Question:	Will this work for my engine if I have a pet goat
Answer:	Only if you have one of those "fainting" goats. All other goats do not make good pets.

User questions & answers

Question:	Hi, does it clean the throttle body valve and catalytic converter? And also does it clean piston from carbon residue
Answer:	Techron has a web site and a contact number to call. Unless someone has opened up the engine block and tested how this additive performs, they are just guessing. Granted, Techron may just be trying to sell you something that you do not need, or need every 3,000 miles.
Question:	Is this product safe for map sensors? (note i did not say maf
Answer:	Don't try to peel it off. Just pierce it through the center (not at the edge) with a sharp pointed blade, like one on a little Swiss Army keychain knife. Leave the slit alone and don't try to peel any of the seal off. If you just pierce it in the center and don't try to pull off or peel any pieces it will remain intact and tightly adhere to the bottle neck and thus continue to provide an effective seal when you close the cap.
Question:	Where do you spray this? Ty
Answer:	Yes, its fine to use. The ingredients don't go bad for maybe 20 plus years or more
Question:	Is this safe to get onto the throttle body plates and bushings?? spraying this after the maf will coat the throttle
Answer:	Both products contain the same cleaning additive (polyetheramine), the "fuel injector cleaner" just contains slightly less (and is usually slightly cheaper) than the "fuel system cleaner".

User questions & answers

Question:	Vehicles have different gas tank capacities? How much gas does it treat
Answer:	Our Intake Valve Cleaner will clean and remove carbon from the combustion chamber (to view results for yourself visit www.crcindustries.com/gdi .) However, this product will not clean the throttle body as the product will just pass through. It also won't clean the catalytic converter.
Question:	Can this be directly added to your intake manifold
Answer:	Yes it’s is. I have used it several times without any issues with map sensor.
Question:	Is this basically a engine flush
Answer:	I have a 97 corolla..... So i sprayed this in the port after the air filter connect to air intake house assembly........
Question:	Will this work on modern diesel engines? specifically a 2012 bmw x5 xdrive35d
Answer:	Yes. You spray AFTER the MAF, you do not want this to get on your MAF sensor. Your throttle body will be unaffected. Let car warm up first for 5 min. Make sure to have someone rev engine in neutral to 2k RPM and hold steady. Spray entire bottle until empty. Let engine heat soak for a hour (turn off engine and let it sit). Then go drive car with some good acceleration and get up to some quick highway speeds. Viola! Done

Can gasoline go bad?

Have you ever thought about what happens to gasoline before it goes into your tank? Gasoline is highly refined to provide the right combustibility in your engine, even blending for optimal performance in different seasons. But as the gas travels long distances from the refinery to the pump, or sits unused in storage tanks, volatile chemicals have time to evaporate and degrade the gas.

Protect the Gasoline that goes into your vehicle

A great way to protect your fuel system from inconsistent gas quality is by adding a treatment of Dura Lube Severe Fuel System Cleaner. This formula helps the gas in your tank burn through your fuel system more effectively, tackling any moisture in the fuel, and cleaning your injectors and fuel lines. It’s easy to use – just add one bottle for 42 gallons, and add a new treatment every 3,000 miles.
