Liquid Performance - Ethanol Equalizer - 2 OZ - Full Synthetic Complete Gas Treatment - Cleans and Lubricates Fuel System - Stops Ethanol Fuel Problems

I try products like this periodically, on the chance they might be beneficial. My only metric for rating them really is pretty much just "did it kill my car." This has not, and I put it in a while ago, so at the worst it does nothing detrimental, at best it will help ensure your vehicle's engine has a long life. My car has around 100k miles so not super high mileage, but it is a V8 and I run it pretty hard, so I appreciate any help in keeping it alive that I can get.

I usually run 89 octane and sometimes 91 octane in my low mileage 2007 Crown Vic LX Sport. I have reprogrammed the PCM with a quality performance tune. Even without that peformence tune, running my high performance engine with the factory tune on 87 octane causes it to ping. So, to give this Liquid Performance an honest evaluation, I had a little less than 5 gallons of 89 octane gas in my car's fuel tank. It holds 19 gallons of gasoline. I filled up with a little over 15 gallons of 87 octane regular unleaded fuel. I then added the entire bottle of Liquid Performance to the fuel tank. I then drove my car normally at times, and other times I floored it. Not a single pink out of the engine. It wasn't long after filling the tank that my car's engine, already running good before using Liquid Performance, was running even better. It had been at least a year before I had put injector cleaner in my fuel tank and even when I did, that stuff never worked as quickly as Liquid Performance did. After running down the fuel tank, I filled up again but with the usual 89 octane gas that I get. What can I say, the car runs like it's got 91 Octane in the gas tank. What a difference a clean fuel system makes.I can't tell you if Liquid Performance works well when using it to preserve the fuel in your vehicle during long term storage. As for how well it works as an octane booster, I can honestly state that this product does just that, as well as cleaning your fuel system including the electronic fuel injectors. I'll definitely be using this product again in the future to clean my fuel system. Liquid Performance is worth the selling price because it actually works.

This fuel treatment is really good, and I have used it in the past on my ATV’s and other small engines. It’s hard to validate all their claims, but I have not had an issue with starting equipment stored over the winter with this fuel treatment. The longest I have ever stored gas before use is a year with any brand, so the claim of 3 years is something I can’t comment on. I do think that it’s on the expensive side and for only being able to treat 20 gallons of gas, it’s significantly higher than other brands. That being said, if you have had issues with other brands leaving you with a non-running engine after a year of storage, this one does not have that problem.

Overall I would say it works decent. I might be getting a mile or two better but who knows, that could just be the way I’m driving too. I will say my car sounds like it idles better though.

I have a car that was sitting pretty much unused late summer into early winter. I had ordered LIQUID PERFORMANCE for that car with a number of considerations. The presence of ethanol and likely water in the gas tank, the non use for a long period of time, fuel stabilization and an octane boost to aid in initial startup and a longer run to "Clean out the webs" so to speak. Well before I got to it the approaching arctic blast worried me so I added it and ran the car at idle for a while to make sure it was mixed into the system gas. After things warmed up I took the car for a two hour drive without issue. It started right away, no power hesitation and both the long term siting of ethanol and water did nothing to the engine. At $10 it isn't cheap, but what is that kind of protection worth? I will purchase again and I : HIGHLY RECOMMEND.
