I own a 2005 Infiniti G35 Coupe 6MT and have been experiencing engine pinging throughout the driving range, primarily between 2-4k RPMs. I saw the previous reviewer said their engine ran fine so it was difficult to judge the effectiveness of the product. Well, I tried Seafoam, STP fuel treatment, octane boosters, etc to no avail, still pinging. I always use 93 octane so I knew that was not an issue. I read on G35 forums where various members were having the same problem and some suggested going a step colder on plugs and oil catch cans etc. I was getting ready to try the colder plugs but decided I would try Lucas Oil Fuel treatment. I've also been using nothing but Shell 93 V-Power as of late and on the next fillup, I used the full bottle of the 16oz. Lucas fuel treatment. After about 3 miles of driving pinging was near eliminated and over the next few days, it was gone completely and my car runs a lot stronger now. I can physically feel a difference so I know there was something at fault in my fuel system. One bottle of Lucas Oil Deep Clean has my car running stronger than it ever has since I've owned it and I will continue to use it every other month or so. It is running the way it was meant to run. I've already recommended it to several freinds and I'm not sure if they will experience the same thing because I was actually experiencing pinging, but it does what it says. Excellent product.

EDIT: Followed up with Redline SL-1, please read that review as it was a better approach and more effective product for my pinging issues revolving around carbon buildup... Gumout Regane is also a better approach for fuel system, combustion, and intake treatments...

My old Kobota tractor was skipping and I thought BIG BILL,so with nothing to lose I tried Lucas 10512 deep clean, after 2 bottles my tractor began running smoothly. This was my last shot before taking the injectors out and having them rebuilt. A tractor mechanic recomended Lucas to me.

In my case, it's difficult to judge whether or not this cleaner is doing its job. I'm using it largely as a preventive measure; I didn't have any engine problems to begin with. I started using this in my car at around 15,000 miles and I am now at about 35,000. Every 3,000 miles, I add it right before filling my gas tank. I have no issues as far as I can tell: the car still runs as smoothly as the day I got it, technicians have not noticed any problems during routine maintenance so far, and emissions inspections are fine. I'm not sure what else to look out for.

I do notice two things about the car when my tank contains this cleaner: slight improvement in gas mileage and smoother idling. However, once I deplete the gas tank and do a fill-up with only gasoline and no Lucas Oil cleaner, the MPG and idling benefits disappear and the car is back to normal. I don't think it would be cost-efficient to add a bottle of this cleaner to every tank full of gas in order to obtain the MPG increase.

Fuel cleaners are hard to rate. This brand has caused me no issues in the two vehicles I use it in. I use at every oil change as a minder. Would rate five stars if it had a site window to determine number of ounces used. My vehicles require 8 ounces only, I can only estimate with this container type.

Only two gasoline fill ups after using this product my gas mileage is up 3+ miles per gallon. I highly recommend this product. Easy to use with great results!

Finally a product that works as advertised! I am completely satisfied with this product. I have tried nearly every other "fuel system cleaner" product on the market, with disappointing results until now. LUCAS Deep Clean Fuel System Cleaner works beginning with the very first bottle. I noticed a huge difference in performance and acceleration ...unlike ALL the other products out there that did absolutely nothing but make promises and delivered nothing. THIS PRODUCT WORKS !!

Just bought a 95 es300 w/ 140,000 but clean clean clean...I mean no dirt 4real...Regularly serviced at Lexus of Greenwich. Only 2 problems motor mount busted & check engine lite on. Not sure if CEL was on cuz of motor mount or what but decided to give Lucas Deep Clean a try. CHECK ENGINE LITE GONE. I normally in all my other cars use the regular old Lucas additive & I been eyeing Deep Clean for a while. i asked the dude at Advance auto if he or anybody knew about Deep clean but all he could vouch for was the regular old Lucas. I told him I was gonna take a gamble & let him know the results...End of the day I'm tryna tell yall GET LUCAS DEEP DAM CLEAN NO BS IT WORKS. & trust me I dont work for lucas or have stox or nada...i read a couple reviews before i put it in

I have a two year old suv that was previously owned and had a lot of miles put on in a very short time. The engine would ping when I would turn off, even after only going short distances. I used this treatment in a full tank of gas and it stopped the pinging and the car seems to run smoother! Will continue this treatment.
