13 best allstar fuel treatments

Allstar fuel treatments, commonly categorized under fuel system cleaners, fall within the realm of automotive maintenance products designed to improve the performance and efficiency of a vehicle's fuel system. Here are some key points about Allstar fuel treatments:

  1. Fuel System Cleaners:

    • Allstar fuel treatments are formulated to clean and maintain the components of a vehicle's fuel system. This includes the fuel injectors, carburetors, intake valves, and combustion chambers.
  2. Deposit Removal:

    • Fuel system cleaners, including those by Allstar, often contain detergents and additives that help break down and remove deposits that can accumulate over time. These deposits may impede fuel flow and affect combustion efficiency.
  3. Improved Fuel Economy:

    • By cleaning the fuel system and promoting better combustion, fuel treatments aim to enhance fuel efficiency. Vehicles with cleaner fuel systems may experience improved gas mileage.
  4. Emissions Reduction:

    • Proper combustion and a cleaner fuel system can contribute to reduced emissions. Fuel treatments may assist in optimizing the combustion process, leading to lower levels of harmful emissions.
  5. Injector Cleaning:

    • Fuel injectors can become clogged or coated with deposits, affecting their performance. Allstar fuel treatments often include ingredients that target these issues, helping to keep injectors clean and functioning properly.
  6. Corrosion Prevention:

    • Some fuel treatments may also contain corrosion inhibitors to protect the fuel system components from rust and corrosion. This is particularly important in vehicles with metal fuel tanks and other susceptible parts.
  7. Use as Directed:

    • It's important to follow the manufacturer's instructions when using Allstar fuel treatments or any fuel system cleaner. Proper usage ensures optimal results and prevents overuse, which could be detrimental to the vehicle.
  8. Compatibility:

    • Allstar fuel treatments are typically designed to be compatible with various fuel types, including gasoline and diesel. However, it's essential to check the product specifications to ensure compatibility with the specific fuel used in the vehicle.
  9. Regular Maintenance:

    • While fuel treatments can be beneficial, they are often used as part of regular maintenance rather than as a solution for severe fuel system issues. Regular use, as recommended, can help prevent the buildup of deposits.

It's important to note that the effectiveness of fuel treatments can vary depending on factors such as the age and condition of the vehicle, driving habits, and the quality of the fuel used.Additionally, some vehicles may benefit more from fuel treatments than others. As with any automotive product, it's advisable to follow the manufacturer's recommendations and guidelines for the best results.

User questions & answers

Question: Will this foul my plugs out
Answer: The final concentration depends largely on the Zn and P in the oil used. With oil containing 600ppm of P and 800ppm of Zn, adding 4oz of ZDDPlus will bring the P to ~1600ppm of phosphorus and ~2100ppm of zinc. Our research shows this to be optimum for high-performance engines manufactured before 1996.
Question: Can you use this in motorcycles
Answer: Thanks for your inquiry. Yes our ZDDPlus can be used in marine, motorcycle and tractor engines. Typical dosing is one 4 ounce bottle per 5 quarts of oil.
Question: Will this work in a 2019 polaris slingshot with aftermarket exhaust system
Answer: I use 1 4oz bottle on a 6 quart oil change in my Cadillac 390. My buddy who is an engine builder says one is fine.
Question: Why would I add this to my fuel? Just for scent? Does it clean the engine
Answer: I have an LT1 5.7 liter from 1995 that the oil cap calls for API SG type oil which had a lot more zinc and phosphorus than today's SM/SN. The bottle of this ZDDPPlus claims that it brings zinc levels back to SF. If your oil consumption is not excessive there is no downside.

User questions & answers

Question: Anyone using this to negate ethanol damage or are you using their other ethanol treatment
Answer: NO, this is not the product for that. You need the Lucas Oil Safeguard ethanol fuel treatment.
Question: Is this a concentrate
Answer: Yes, 3 oz. per 10 gal. of gas. You do not add anything to the fuel treatment.
Question: Would keeping this in the car in hot Texas heat be an issue
Answer: I use it in almost every fill up on my truck. F150 in SoCal heat.
Question: Will gas mileage increase
Answer: I drive (and now use this in) a 1996 Toyota 4Runner. Prior to its use I'd averaged 17mpg, then performed a replacement on plugs, wires, and air filter (upgrading to a K&N); in addition to cleaning the MAF and throttle body (all on my own, mind you!). I now average anywhere between 19.5 (city) and just under 25 (highway). I'm not sure just how much of a fuel increase can be contributed to this product, but I no longer go without it!

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.

User questions & answers

Question: I intend to use this to stabilize gas stored in storage containers for use in my generator and snowblower as needed. Any issues for this usage
Answer: I have used it for that purpose for years and it seems to handle storage issues just fine. I have had the same gas in my old farm tractor for several years and it still starts instantly any time I want to use it.
Question: year old tank of 2-stroke gas in jet ski. What to do with gas
Answer: Drain it and dispose of in accordance with local and state regulations. Call your local solid waste department or a local fire department or an auto parts store/repair facility to determine who can accept old fuel for disposal.
Question: Is this useful in old engines using now using "REC 90" (old fashioned) gas
Answer: Star Tron is formulated to be used in all "gas" to include gas blended with ethanol (e10) as well as ethanol-free gas (Rec 90). Star Tron can be used in all engines, both old and new.
Question: Does it need to be mixed through-out the tank. or is it ok if startron were added to a full tank because it will then blend with the rest of the gas
Answer: I have a neighbor who had a 200 gallon tank 3/4 full of old fuel. He treated the whole tank with startron and I suspect he over dosed a. It knowing him. He let the tank set for about 30 hours and the whole tank was treated and acceptable when he opened the spigot on the tank. It’s easy to tell bad fuel by the smell. It’s also easy to tell your fuel has been recovered by smell. He used all 150 gallons and even fueled up his 2018 Corvette with fuel from the tank.

Question: how come i was charged tax on a fuel treatment additive being sold by amazon...but not on other items being sold by other sellers
Answer: From my understanding it’s because the seller is in your state. When you buy product from seller or of state there are no taxes. That’s why the government is trying to pass new laws to be able to tax the products.
Question: Do you pour in the whole bottle? I have a 1998 vw jetta
Answer: Yes the entire bottle
Question: I put it in with a half tank still in the gas tank then filled up will that effect how well it works
Answer: This Rislone stuff works REALLY well, especially if you've never used a fuel system cleaner to clean your fuel lines & intake. To get the maximum cleaning effect, you should run your tank down to 1/5 of a tank, and THEN put in the whole bottle and drive your car around until you get down to only 25 miles left and THEN, fill up to ONLY a 1/2 tank. This is my only "system" and it's not what they say to do on the bottle. In essence, when you put the bottle in, with 1/2 a tank and THEN, filled up.....you just diluted the strength of that 1 x bottle, by adding all the extra fuel. Try doing what I suggested and it will clean your fuel lines out very very well plus any carbon buildup within your intake or combustion chamber. Good Luck.
