The best can I have ever used; no spills, no drips. Auto shut down of gas flow if you cannot see the level of gas in the tank. I use this on my boat so I don't have to pay nearly $5.00/gallon at the marina. Only thing you have to be careful of is the small "O" ring coming off the shaft if you use the extension spout

Motorkote is the best stuff on the market for protecting your stuff. It makes engines run smoother and quieter. First hand experience. You can use it like WD-40, but it lasts longer. I didn't have any dramatic improvement in gas mileage but when I used the fuel treatment it helps a mile or so on the gallon. It doesn't matter how good something is, there will always be a disbeliever. Sometimes you have to just try it for yourself, I did and I'm glad I did. Motorkoter for life. Thank you.

I first purchased the smooth version of the Permatex product at Tractor Supply who sadly stopped carrying it as did many of our local automotive vendors.

Permatex as a company has been around for years and is known for quality and I use and would gladly endorse many of their products. Please, if anyone at Permatex reads this thread, PLEASE keep making this, it's the best hand cleaner I've used.

I'm always working on machines and often find myself elbow deep in grease. When I'm really covered with grease I first rub the cleaner thoroughly over the area I'm cleaning and then wipe it off with a paper towel. Sometimes I repeat that process if I'm really dirty, always wiping off with a paper towel. If my finger nails need attention, then I use a finger nail brush, and lastly finish the wash up with a good liquid hand soap.

I cary a small bottle in my car as well as to the race track if I'm racing. It doesn't dry my hands out like the pumice type hand cleaner. And as others have stated it can be used to remove grease and ink stains from clothing. Rub it in and toss the soiled clothing into the wash. The large hand pump container is really convenient too.

I have a 1993 Ford Escort that has steadily been running worse and worse. It would take me FOREVER to get up to speed! I decided that I should probably get some kind of fuel treatment,  so I went to Walmart to check some out. I've tried a few in the past that didn't really work very well. I read a review that made it sound pretty good so I decided to try it. As soon as I drove out of the parking lot of the gas station after filling up,  the car ran like it was brand new! It was like magic! Anyone who wants their car to run brand new should get this! Don't waste your time trying any other fuel treatments! I promise you will not be disappointed!!

Best thing for fuel injectors ever invented. Litterally saved me from replacing them in a car I owned many years back. I run it in all of my cars twice a year with a full tank of super. Keep things nice and clean and running smoothly.

this is a great product that pays for itself!

nobody knows what additives are left out of today's generic gasoline.

regular use of Lucas fuel treatment keeps your injectors clean and your ensures your emissions equipment is functioning.

as an aside, using the lucas along with changing your fuel filter at recommended oem intervals and properly inflated tires will optimize your car's mpg's.

you should also use this product in your lawnmower, snowblower and other power equipment along with the lucas ethanol stabilizer to keep all your yard equipment running  like new.

Of the CARB Compliant fuel cans this is the best.  I bought a 2nd can because a non No-Spill I bought in 2008 (Plastics Group W520U) just split the breather cap in half.  California oxygenated gasoline being what it is, the vapor pressure is so high any leaks gas out my garage.  Also, the W520U bulges and turns from a rectangle into something resembling a beach ball.

The No-Spill doesn't leak and holds up to the high vapor pressure without bulging and turning into something resembling a beach ball.

This fuel treatment by Lucas is the best on the market in my opinion, I use it regularly in my vechiles and I have yet to have any problems with my fuel injectors, and both vehicals run smooth  and 1 has over 125, 000 miles.

I use this each year for my motorcycle and lawn tractor and lawn mower fuel tanks to eliminate stale fuel problems in the spring when all are started up again for regular use, the price was right and it was delivered quickly too, packaged well etc.

It's good stuff for cleaning fuel systems even on regular use applications and often one might notice their mower or motorcycle or even automobile running better after adding it to the fuel and driving it a few miles..

I highly recommend this product, have used it for years and swear by it.

Folks, I took my car in for normal maintenance, and of course they recommended a fuel system cleaning. However, the service advisor made a point of telling me the product they used. This one. Save yourself over a hundred dollars and buy this. Just add it to your tank prior to filling up and wait for the magic. You won't notice a difference right away, but suddenly after a quarter tank or so your car will suddenly regain the power it had when it was new and rin a lot smoother. I can't really attest to mileage savings as I have one of those cars with the high compression ratio so the mileage is already very good, but I assure you will notice the increased performance. To my knowledge, they don't sell this in auto parts stores, (at least in my area) so I'm really glad I can get it here!

dont hesitate buy this ive never been able to clean a car better and faster, cracks and places where it takes awhile to clean is a breeze with the right chemical,  i will never use small brushes to clean in a car again period!!!! also takes out bad stains in carpet one pointer id advise is buy an extra weighted tube because u may need it , now with that said i don't mean ur gonna be going threw them just once in a great while, do not power over 90 psi or u will damage weighted tube and have to replace it and have a bucket with clean water by and if ur cleaning something really dirty place the nozzle in the bucket and trigger it, it cleans the inside of the horn n keeps the weighted tube from making deep groves in the horn part, don't be scared off by any of this just a small couple points u won't regret buying this at all!!!!

This cleans your fuel system, and improves performance mildly.  I use it mainly to keep the system clean, and the multi-pack is nice for cost savings.

Works great combined with the fuel treatment.

This is one of the best cleaners-degreaser I have ever used. The smell isn't over powering like other cleaners. This is the only cleaner I will use on my stove to clean it with.

As of my writing, the Gumout Regane High Millage formula contains both a decent amount of PEA (the best engine deposit cleaning detergent) and an Upper Cylinder Lubricant. I'm not sold on the benefits of UCL, but this is one of the best fuel additives in terms of cost/benefit. Like all fuel system cleaners, it works best as preventative maintenance - it's easier to avoid deposits in the first place than clean up deposits after they happen. If you're trying to clean deposits, you'll want to run double the concentration and/or add it to several fillups back to back. Otherwise every 1000 to 3000 miles depending on your engine and quality of fuel you buy.

I put this in every car I own to keep it running well. This is a concentrated version of the additive Chevron puts in their gas. Highly recommended for keeping your engine running cleanly.
