Questions & Answers

How much jail time will I get for using this product? It says that it is illegal to use on the street?

If you steal a car and add it to your car's tank and, while driving it, encounter a police road block similar to those used for alcohol checks, where the police take samples of gas in your tank, you will get a fine and you may lose your car. I guess science fiction is fine. Reality tells us that if you were to crash into an innocent driver while street racing, they would add a fine to your account, which, of course, would be silly at that point too. So yeah, I just had to do a mental process--it

There is a 6pack listed on the item title? Are you misleading or just trying to mislead?

This is not a 6-footer You have packed

Do you think this would work with a 2 stroke engine?

Rather than engage in it, I would seek other options. You will foul your plugs pretty quickly when you use it, and it doesn't seem to have any additional benefits.

The oil control rings are cleaned well by this product? What is the best way to test the engine without taking it ?

The product is an octane booster rather than a cleaner, and you should buy a different one

The M4 GTS became more powerful as a result
5/5

You have done a fantastic job! Using it with my 2016 M4 GTS, it works flawlessly. In my case, I added it when my tank was running low, then I filled up the rest of the tank so everything could mix. As I said, I was skeptical initially, but the performance improvement was noticeable. A bit of background here is that I was living in California during the time of testing, and the only available fuel there is only 91 octane rather than the recommended 93. You may think it is not that much of a difference, but my tests show otherwise. I'll dyno the car later on to prove my point. The engine sounds much happier when this is in the tank because it sounds more aggressive and burbles. The same result was obtained with my 2013 Honda Accord, in which no difference could be detected. I haven't noticed a difference in MPG at all, at least in the cars I drive. If your car has a higher compression ratio and therefore benefits from high octane, then this is a highly recommended option for you. It gets 10/10 from me, I use it every time I fill up, and I keep one in my trunk.

This is the best cleaner I have ever used for fuel systems
5/5

This is the best cleaner I have ever used for fuel systems. In addition, I also let my 2000 Ford Ranger sit, which resulted in my gasoline losing its muscle. There was something wrong with the way my vehicle drove. The product I found to be the highest rated one out there after doing some research. The next morning, I poured the mixture into my tank and let it sit for 24 hours. A noticeable difference in performance was immediately evident. It would have been faster if I had done it as PM years.

A genuine octane boost is needed in my vehicle, and this does so
5/5

My vehicle is a 1965 Triumph with a milled cylinder head The first owner of the car performed these modifications around 1970. In April, the engine has not been rebuilt (since April, the engine has not been rebuilt). A pinging problem occurs when going uphill with a light load. The only product that works is this one. It usually lasts me an entire year and a half, since I don't drive the classic all the time. There have been no additional issues with this classic since I began using this product (misfires, smoke from bad rings, etc. ). In my experience, using this product does not have any impact on MPG or performance. If you find yourself unable to get enough octane from pump gas, I recommend trying it out.

I love this product! Could you please tell me what you think? It has always been a little strange for me to buy products that claim to do all kinds of things
5/5

In the past, I've tried others without any noticeable results. The engine in my 2007 TC is running a bit sluggish at times. The car has over 105 thousand miles on it. The first time I tried this, I wasn't pleased with the results, but after two days I jumped on the freeway and I was pleased with it. There was definitely a difference in the sound of my car's engine. It's also more powerful and is running smoother. It is highly recommended that you try it out. Take a stab at it. Suddenly a thought came into my head. If I run a second cycle through it, will it work? Then I may do it one more time to make sure my engine runs even better! You always seem to get it with a huge dent on the container according to someone else's review. As well, I found several dents on it. Yet it doesn't impact the contents of the web site more of an eyesore.

Boosts octane to an excellent degree
5/5

There is an incredible difference between Mercury Marauder and 93 Octane tunes. Among all the octane boosters out there, this is my favorite. In my 2003 Mercury Marauder, all stock motor except for 93 octane tuning has been done. When I bought it in New York, the car had been tuned to run on 93 octane when it was originally built with a naturally aspirated engine that requires 91 octane. Despite my best efforts, I realized the hard way that premium gasoline becomes 91 octane rather than 93 as you travel further west. Although my car runs on 91 octane, it doesn't possess the same acceleration or "get up and go" feel that it has with 93 octane. By increasing it by 3 points, this effectively raises the octane to 94. Using a bottle of this with 91 in a tank of 94 octane is the best match. It has given me the best performance of any octane booster I've tried, plus I trust it when I pour it into my gas tank since it's made by a respected brand. Great product, useless if you don't have the engine that needs it. When I see people filling up a regular car with 91 or 93 octane because they call it "premium" fuel, I laugh.

My beautiful Vette did not make it through the night
3/5

Thanks for stopping by! I have to admit I was initially attracted by the packaging, labeling, etc. Following that, it was the 30 point boost that was It was with great anticipation and hope that I bought a can of gas to go in my Vette However, the product dropped my mileage from 30 to 10, as opposed to increasing it. I find it especially hard when I am not at all sure what is going to happen. An individual who is 13 years old can decide for himself.
I have a '13 Grand Sport that I already drive, so any data in the way of speed or power didn't show up. I hate it.

This is great if you need to tune your car
5/5

Makes sure that your "93" gas is at least 93 octane. Every time I top off my 93 octane minimum tuned mustang, I use half a bottle.

I DO NOT recommend using this! drinking 3 bottles of the same brand in 4 months, I began to notice negative effects that I had not experienced with After strictly following the directions, I noticed nothing after the first bottle, degraded performance of my car and exhibited a brown stain after the second bottle, and further stained the car after the third bottle
3/5

There was a problem with this product on my R34 Skyline. It disappointed me more than other brands because I expected more from it. Engines with turbochargers do not work well. Besides clogging exhaust manifolds and leaving a thick brown stain on the straight pipe and catback exhaust outlet, this substance also causes odors. I DO NOT recommend using this!.
