Never used before and had to try something different. It really worked. Smoothed idle no vibration from engine. I'm sold.

Yes, I'm a believer too! I have a 2004 Mercury Marauder with the 4.6 4 valve cobra motor in her, I was experiencing hesitation under normal acceleration, and full throttle, I added this today, and the hesitation is all but gone. Good stuff!

My #2 injector clogged for having crappy contaminated gasoline where I live. Before spending money on a new injector and labor, I did a hail mary and added a full bottle to half a tank. The thing unclogged and it's now running smooth. Still adding half a bottle every fill up. It really works.

I've used this stuff for years. It does work very well. Use it both my car and my truck. It also worked wonders on my fuel injected 2009 Honda 4 wheeler. It is not just for fuel injected vehicles. I use it in my carbureted lawn tractor and my snow blower. It cleans carbs just as well. Excellent product.

I use it in our 01 excursion V10 and our notorious GM 3.6 V6, it does work wonders.

My Ranger has 370000 miles with no oil usage running Lucas for 13 years every gas fill.

Used Lucas FIC for years. Great product. Have a 2010 CTS for over 11 years with over 112K miles & it runs as good as new. Just sold a 2012 Ford Fusion with over 242K miles & used the Lucas FIC in it also. The Ford also ran as good as new with no issues.

My check engine light was on for my 2009 Kia, and it was running pretty poorly with hard idles. Through a bottle in and it cleared everything up. Light went off after a while and the engine sounds brand new. Amazing stuff.

"Drove it around the block and it was running better". Seriously, Dude? That's not even enough time for the Lucas to make it through the fuel line and reach your engine.

Most likely the fuel injector had deposit build up and didnt allow for the correct fuel to air ratio in the combustion chamber which was causing the rough idle. The lucas cleared up the build up and fixed the issue. Easy fix.

I remember running it through my old 5.7tpi suburban years back and saw an immediate mpg increase.

Been using Lucas tune up in a tube, for 35 plus years, add a bottle every 3-5 tank fulls, never had a warning light on dashboard of any vehicle, nor had MOT failure on emissions on annual test ( smog ) does exactly what it says on the tin

I use this stuff all the time. Car (2016 Ford Edge 2.0 ecobust I-4) improves MPG by 5 gallons, and I get 32 MPG vs 28 MPG.

I've been using this more regularly lately, since gasoline nowadays has more ethanol (dirtier)

Sad how many professional mechanics say additives don't work. Yet, us out here who have proven results know better.

My toyotaco prissypoo 2.7l sure gets better mileage with lucas cleaner. Mine took 3 tanks. I park more than drive.

I have never tested it but I buy the big bottle and fill the little bottle up once in a while, just to keep my fuel system good.

Upper cylinder lube and cleaning agents. These products quieten the motor.Adds smoother power. Prevents the issues coming back. Pleased you had great results 👍.

I started using it and my fuel mileage went up from 31.4 to 36.9 after A half dozen tanks of fuel. I will be buying the gallon jug because it is cheaper and refilling my liter bottle up with it.

I'm looking forward to seeing a review on headlight lens polishing products :)

Great running car cuz of a great mechanic!!

I run Lucas in my motorcycle and my Cadillac.They run like a clock with Lucas.

Forest Lucas has a beautiful ranch in hickory country mo he's a real good man

What the hell are those engine mounts, ive never seen some shit like that

If you're getting over 7000 rpm you need Lucas.

I buy the bigger bottle, and refill the smaller bottle. Better value, also I add the smaller bottle to every time I fill up. Seems like a waste, but my 2006 Chevy Colorado with over 200,000 miles runs like a top. I purchase the larger bottle on sale for $12.00, and I can get six smaller bottle refills.

That’s the brand I use ! That stuff works well.

You have to put that stuff when you get a car that is new like 10 k miles or 40 k after 70 k and you never put that your car is doom or lose power that will help it but the seal are damage

Do not use gasw/ethanol inside. Use only premiun gas all the time w/ethanol. This stuff is good for long time to clean injectors, for the rest I'm not sure. What means 5 $ more at the 60l tank gas price.

I used it in my gas tank after I changed plug and wires 2 days later my injection not working and car stuck

That's cool I wouldn't expect it to work that fast but it's nice when it does

There is nothing in a can or BOTTLE that you can pour in a diesel or gas engine to help performance. Fuel filters in a box will clean injectors, changing coil over plug rubber insulators will stop miss fires .

Use the highest octaine fuel you can get.

And look like your car is still misfiring or rough idling because the bottle of Lucas is still shaking about to fall over LOL

Hey

Sorry I won't talk about a car
