User questions & answers

Question:	Do people really use this every 3,000 miles? How often do you do it
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:	it's a real pain to open Techron bottle's seal. do you guys have any tips on opening it easily
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:	I found an old unopened bottle of the original concentrate, not the Plus. Probably 10 years old. Is it still OK to use
Answer:	Yes, its fine to use. The ingredients don't go bad for maybe 20 plus years or more
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
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".

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.

Answer:	pro guard is not as concentrated as the full strenth black bottle that i have used for years at my repair, with the new fuel injection systems that have come out the last few years,They have carbon built up problems on the valves.I would only use the full strench in my cars every oil services

Product description

Lucas Fuel treatment complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road, locomotive and marine diesel equipment engines. A powerful blend of oils and additives that contain no solvents. Designed to increase power and fuel mileage and also lower exhaust emissions through a more complete combustion. Formulated for both gasoline and diesel engines, carbureted and fuel injected. It gives your fuel system what it really needs - a blend of super slick oils and additives with a high detergent action that allows the engine to operate at maximum efficiency. Also, it cleans and lubricates the carburetor and injectors and causes the fuel to burn more thoroughly for increased power and less fuel consumption. Lucas Fuel Treatment should definitely be used in vehicles that require leaded fuel because it actually replaces the benefits of lead in gasoline without causing harmful emissions. Use it to pass smog tests. Finally, it totally neutralizes the harmful effects of low sulfur diesel fuel.

• The product is 5, 25 ounces, fuel treatment, for gasoline LPG and diesel fuel, contains no alcohol/solvents/kerosene/diesel fuel, lubricates rings and cylinder walls for longer life, increases mileage, cleans and lubricates valves, pumps, carburetors, and injectors
• Easy and simple use kit
• The product is manufactured in China
• A great tune-up in a bottle
• Cleans and lubricates the fuel system
• Neutralizes low sulfur fuel problems
• Increases power and miles per gallon by burning excess exhaust emissions
• Increases the life of pumps and injectors

User questions & answers

Question:	How often can you use
Answer:	I use this on every fill up because it lubricates the upper cylinder which increases my gas mileage by about 9%. So it definitely pays for itself. Tho I buy it a gallon at a time and use the smaller bottle to pour into my gas tank. Also, I only put about 7 or 8oz in a 20 gallon tank. Too much of this stuff actually lowers gas mileage. I know from personal experience. If you're looking for a one-per-year cleaner, you really need to look at Techron. This Lucas Oil fuel treatment isn't a strong enough cleaner to use only once per year. I use Techron every other oil change to keep injectors and whatnot clean, but use this Lucas Oil treatment for MPG gains only (from lubricant affects).
Question:	Can i Use this in a Toyota corolla 2006? and how often should I use it
Answer:	My Toyota dealer sells this product in their service dept
Question:	Can I use this in my 2012 kia sorento
Answer:	You have to add this before you fill your vehicle up. That way the very action of the pump pumping gas into your vehicle mixes up the Lucas Oil. You don't want to put it in after you filled your gas tank
Question:	Will it help remove P0420 code
Answer:	2 bottles of Lucas oil, one gas refill apart, helped with my P0420 Code on Infiniti QX60 engine light. With the 2nd bottle, the light was gone. It worked like a charm. I will continue to keep the fuel tank clean moving forward. Tip : don't wait for the fuel tank to be completely empty before you refill.

• Better throttle response
• Cleaner combustion

User questions & answers

Question:	Here's a question: What is the difference between a fuel injector cleaner and a fuel system cleaner? Don't they all go through the same paths
Answer:	This is also why it is a good idea to follow this treatment with the fuel system cleaner so the injector cleaner is flushed from the fuel system.
Question:	do I use this every 3 months
Answer:	So many factors really matter. For instance if you live in a cold place and deal with stop and go, you will most likely have more carbon build up. Also if you only do short trips. I would usually add one bottle ever 3000 miles or every oil change for my Rav4 at 5000 miles.
Question:	What's the difference between this and lm valve clean? ty
Answer:	Jectron is designed for fuel injection system cleaning, smoother idle, improved throttle response. Valve Clean is specifically engineered for removing harmful deposits on valves and in the combustion chamber. It will also have beneficial intake and injection system cleaning effects; but its primary duty is valve deposit reduction.
Question:	PUT IN IN 18 GALLONS, 1/2 tank, or 1/4 tank

Question:	Will this Redline product damage my 02 sensors with LONG TERM use? No one seems to address this issue
Answer:	20 year auto tech. No. The O2 sensors are designed to detect changes in fuel. Specificly the air/fuel ratio. They are not as fragile as most people think. They in no way could be damaged by using this product. This is actually the only thing I use and can highly recommend when it comes to fuel additives.
Question:	Is this product better than the much cheaper STP fuel cleaner
Answer:	I'll tell you this the difference being only a few dollars considering this product is in the $10 range I wouldn't bother trying anything else. I'll admit I've never tried any other product, but 2,200 mile after the first use I still see a node improvement in the fuel economy and have the smooth acceleration. I'll he sticking to the every 5k recommended use. Hope this helps

(if you smoke, put the cigarette out before proceeding further)open gas tank door. remove gas cap (place in a location you remember to reinstall later.)Pour contents into gas tank. Replace gas cap. Drive as normal and it will clean injectors up as you drive. Enjoy a beer (AFTER you drive with enough time in between to sober up.)Call the fellas up and stand around drinking beer while admiring a fine product from Redline.

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:	I have a 2010 honda civic ex sedan. what is the difference this stuff and lucas 10003 upper cylinder lubrication & injector cleaner 32 oz.? thank you
Answer:	Different stuff in them, but both are suppose to lube the upper cylinder real deep like..
Question:	I have a 2002 dodge ram 1500 engine size
Answer:	I've used both of these products to clean my engine internals, fuel system etc. I have an Infiniti G35 with a 3.5 V6. I can't really speak to the difference between the two products in detail other than reading and researching the ingredients and purposes of each. However, I used to have really bad pinging due to carbon buildup and tried Seafoam and Lucas deep clean... But I found that they relieved symptoms only temporarily. Now I exclusively use Gumout Multi System Tuneup as it works much better than Seafoam and Lucas. It has a higher concentration of P.E.A. which is scientifically proven to clean engine internals and fuel system components. I would also give high marks to Redline SL1 and BG 44K but they are more expensive. Watch reviews/tests of Gumout MST on YouTube via Scotty Kilmer and several others... Best of luck to you...
Question:	How many gallons does it treat
Answer:	I think it cleans up to 25 gallons. I use it once a month and wont use anything else. but i also drive about 1000 miles a month. Just dont over use it or it will cause some problems. Keeps your fuel system and intake clean.
Question:	Just purchased and need to put into my car. I have a half a tank of gas in the car. Does this need to be put it when tank is near empty only
Answer:	No, you do not have to wait until nearly empty to use the product. Per the instructions, one container treats up to 20 gallons. Obviously, more will be required for more than 20 gallons. Pour the container(s) into the fuel tank, top off with fuel, and go. The product is highly concentrated and really works great. I recommend using one bottle every 3 - 5000 months miles. I believe in this product wholeheartedly. Hope this helps.
