Lucas Oil 10003 Fuel Treatment - 1 Quart

I'm impressed! I didn't expect this to work, but I actually noticed a few things:- Car starts up much faster (less "cranking" required to start the engine)- Feels a bit smoother and more powerNot sure if its placebo but it definitely seems like it works! Considering this is so cheap, I will definitely buy it again.

I've been using Lucas Oil Fuel Treatment for the last few years, specifically after every oil change on my cars. Initially, I used the 5.25-ounce version, but I realized that purchasing the 1-quart version is more cost-effective.Performance:The results have been impressive. My average miles per gallon (MPG) typically hovers around 30-31. However, after using the Lucas Oil Fuel Treatment, I consistently see my average MPG jump to 36. This improvement is based on my daily drives, which involve 50-70 mph speeds over 3-6 hours.Cost Efficiency:Switching from the 5.25-ounce bottle to the 1-quart version has been a smart move financially. Not only does it save money, but it also reduces waste, as I'm not tossing out small bottles every time.Effectiveness:Lucas Oil Fuel Treatment has proven to be highly effective in enhancing fuel efficiency. The noticeable increase in MPG has made it a staple in my car maintenance routine. Given the amount of driving I do, this product not only saves on fuel costs but also seems to improve the overall performance of my vehicle.Pros:Significant increase in MPG (from 31 to 36 on average).Cost-effective when purchasing the 1-quart version.Easy to use, just add it after an oil change.Potentially improves overall engine performance.Cons:None observed so far; the product delivers on its promises.Lucas Oil Fuel Treatment is a reliable and cost-effective solution for anyone looking to improve their vehicle's fuel efficiency. The substantial increase in MPG is a testament to its effectiveness. Whether you drive long distances daily like I do or simply want to get more out of each gallon, this product is worth considering.

I received my gallon of Lucas oil treatment today, put 30 ounces in tank of 30 gallons fuel, 06 dodge 2500 hemi engine, i had to see results to believe it, instantly engine ran smoother i could not believe it without seeing first hand , i will be using Lucas treatment for ever now, thanks Lewis , the engine ran so much better i had to go for a 10 mile drive this is going to be a miracle. This is a update i have used this Lucas in my john deer riding mowers makes them run better and start without using choke to start engine, used in Husqvarna leaf blower could see big difference instantly, i am 83 and this is a miracle product, without seeing would not believe. Thanks Lewis

Let me start off by saying I can't speak to the MPG increase that others claim - I'm not saying that it isn't there, but all of my machines are gas guzzlers at heart to the point I simply don't pay attention. That said, I add Lucas Fuel Treatment to everything I own from my C8 Corvette, my boat with the 496 MAG HO, truck, jet skis, mowers, pressure washer, 4 wheelers, side by side, etc. Along with some other 5 star products that I'll mention below.My primary reason for use is it's an upper cylinder lubricant. I do also run SeaFoam Marine in all of my equipment as well mainly for cleaning and fuel stabilization - I prefer Marine over the original SeaFoam because it does not contain alcohol. I'm not saying that Lucas doesn't do the above because it does, but Lucas is much thicker making it a better lubricant (in my opinion) where SeaFoam Marine is somewhat thinner and to me the cleaning properties are a lot better as that's what it was designed to do years ago. You can mix and match these as you please, and you can't overdose your engine.Here's my strategy:Lucas Fuel Treatment: great upper cylinder lubricant for heavy use situations (high RPM use like 4 wheeler engines, tracking your car, heavy towing etc) Add pretty much every time I fill up, and I add a heavy dose to my truck before I do any towing. Also keep topped up on Lucas heavy duty oil stabilizer.SeaFoam Marine: one of the best injector/carburetor cleaners you can use and an equally good fuel stabilizer. I've added this to 2 stroke fuel mix for my weed eater almost 4 years ago on the same fuel and still runs flawlessly. I add to my road vehicles every so often for cleaning and before any long term storage, however I add to my smaller engines almost every fill up (ATVs, UTVs, mower, jet skis, etc) If you don't want to spend the extra money on SF Marine, the original is still fantastic. But if you are running non-ethanol fuel in your small engines, it makes sense to use the Marine so you don't add any alcohol to your fuel. Had a hesitating fuel injected 4 wheeler that had been sitting for months, stalling at idle. Added a HEAVY dose of SF Marine through it (to the point I could smell it burning out of the exhaust), did a few 3/4 throttle runs up and down the road and it cleared it out quickly. Ran as normal it for the rest of the trip and completely eliminated the stalling/hesitation.STAR BRITE Star Tron: when heavy cleaning is needed. Have injectors or carbs that are heavily clogged and gummed up? This stuff should loosen it up. Minimal lubricant properties, only use when needed.All in all, you can't go wrong with anything from Lucas or the above brands. I've tried to turn people on to these before and have been met with "it's snake oil, not needed" however I haven't had a SINGLE fuel issue in anything I own since following this strategy. Today's fuel sucks and a little preventative maintenance goes a long way.

Product was in good condition and then delivered the next day

My gas mileage in my 2021 Honda CRV had dropped dramatically. One bottle of this into my tank and within FIVE miles, my mileage had jumped up 5 mpg. Well worth the money!! I’ll add it every 3000 miles from now on!

I have been using Lucas Upper Cylinder Treatment for years. I use it in all of my cars and my boat. I like the fact, that I can get it really quick on Amazon. Great product.

Beware if you have a newer vehicle with out a gas cap (Fords and Hondas for sure) these gas necks have a flap about four inches down that the gas nozzle opens. It you try to pour the Lucas lubricant into the tank without opening that flap… it will back up and you will have a mess. Wound up getting a clear 5/8” hose at a hardware store to open the flap , then squeeze the oil from the quart container into the tank. It work, but it’s not the best. You don’t want the hose to fall into the tank. I did not see an Amazon solution to this issue. But the engine does run better and mpg is good. If you snip off the nozzle on the bottle, find a good cap or the oil will go everywhere…
