The great people at Lucas Oil have produced a really good product here. It is extremely versatile and suitable for just about any engine out there, perfect for easy to perform, time-saving maintenance. When you look at this product a little closer, it’s easy to see why it’s so good.
The product is designed to be extremely safe to use and thus contains no solvents, alcohol, kerosene, diesel fuel or anything else that could damage engine parts. It consists of various super slick oils and additives which are designed to lubricate the various systems it flows through, as-well as helping break up gunk in the injectors. This allows the fuel to burn more effectively within the engine, reducing fuel consumption. It is also able to replace the benefits of leaded fuel without the negative side-effects, so it’s great for use in older vehicles that require leaded fuel. And because it also neutralizes the harmful effects of low sulfur diesel fuel, it is similarly great for use in any diesel engine.
Here’s a great video showcasing how this additive increased MPG by about 20%, now that’s amazing!

One of the methods that this product uses to achieve these results has got to do with replacing polymers. Basically, most low sulfur diesel fuels and gasolines have had their polymers removed to comply with the government regulations for reducing fuel fumes in the air. While the goal was achieved, this also caused the fuel to become less lubricated and thus less efficient. We have cleaner air, but less useful gasoline.
Lucas Fuel Injector Cleaner replaces those lost polymers with a specific concentrate that has none of the negative side-effects of the polymers.
Instead, the concentrate works as a lubricant that makes the fuel slicker and more efficient and powerful. Not only will the increased fuel efficiency result in lowered fuel consumption, it also increases power while reducing emissions. Slicker fuel also helps to lubricate the cylinder walls and rings, prolonging their life-span. And not only that, intake valves, pumps, carburetors, injectors and compression rings are also lubricated. An absolute must for rotary engines.
Any way you look at it, this Lucas fuel injector cleaner is a winning product. And don’t worry about shelf life, it lasts just about indefinitely.
How to use?
- Pour Lucas Fuel Treatment directly into the fuel tank.
- Recommended dosage is 2-3 ounces of Fuel Treatment per 10 gallons of fuel.
- Exceeding the recommended dosage is not harmful to your vehicle (but why be wasteful).
The Lucas Fuel Injector Cleaner is without a doubt one of the best products on the market. No wonder it is our top pick when it comes to injector cleaners. Many cleaners make aggressive claims about their effectiveness, but most fail to deliver.
Not the case with this Lucas Oil product. Whether you are looking to clean your gasoline or diesel engines because of clogging symptoms or simply looking for a fuel additive to give your engine a little oomph, this is the product to go for.
Pick the suitable container size for the amount of fuel you want to treat and enjoy the benefits!
I use a full 6 ounce bottle of Lucas in every 10 gallons of gasoline. This is slightly more than recommended, but will it damage my engine?
No, there should be no danger from using too much. Of course I don’t recommend overdoing it, but what you did is perfectly fine if you ask me.
i use it for highway driving as i have a car that is not great for that. i noticed that the more i use the slower my gas tank burns. I put in about a litre and a half and did about 500 km on about 6 gallons of gas
I Accidently put. Upper cylinder lubricant when I changed the oil! Will this hurt The engine
Not designed for crankcase. Oil flush and change recommended after mistake.
I used 4 oz. in 9galons of gas, and the car I running worse than before. the engine is a 1997 ford 4.6l v-8 . had hesitation when accelerating at 30+ miles. now its constant????//
It may be doing what you claim,however it was not a direct cause from using Lucas. There are a lot of factors you did not mention,i.e. age, mileage, driving conditions, type of fuel,altitude, temp.,weather,etc.Anything is possible- but I would bet the farm that Lucas is not the cause of any negative effects if used as instructed.
I used the small bottle, and it fixed the majority of my problem. Though it is still jerking but only at 60 mph, and just slightly. Could I go ahead and already use another bottle?
Is it safe to use in a motorcycle
Lucas is the best! I use all there products oil and fuel all the time. I have a 4.6 liter V-8 and get about 30 mpg !
does this additive damage the high pressure fuel pump on a 6.4 power stroke?
I used Lucas Fuel Injector Cleaner on my 1990 Corvette I think it took out 4 fuel injector
Not sure if I understand you right… you used the Lucas product and it damaged 4 fuel injectors? I don’t think it’s possible to damage your fuel injectors even if you massively overdose with the cleaner. Maybe with some very strong cleaners, but Lucas products shouldn’t damage the engine or the parts in any way, no matter how much you use.
It’s possible that the cleaner dislodged some pieces of dirt and debris from the injector nozzles that caused the engine to behave weirdly for a bit, but that’s all I can think of.
When in doubt – always take the care into the shop and have them take a look. But I seriously doubt the cleaner did anything bad. It’s possible that the injectors were already failing due to age for example and this is just a bad coincidence.
(It’s possible that the cleaner dislodged some pieces of dirt and debris from the injector nozzles that caused the engine to behave weirdly for a bit, but that’s all I can think of.)
I think that happen to me, the engine kind of shaking a little a bit one day. Is it only because of the debris it’s taking out that it is acting like that? Or is there more you can think of? Thank you
I’m a retired truck driver. I was a owner /operator for 36 years. I have used Lucas Fuel Injector cleaner in everything I own, gas or diesel. I mean from my genarators, lawnmowers, weedeaters,chainsaws,cars, pickups ,diesel trucks and reefers for years and have only had to change ONE injector in all that time. I put anywhere from 5 to 7 hundred thousand miles on my trucks before trading them. I’m a firm believer in this product and recommend it to anyone that asks me. I would really be surprised if it hurt your engine. This gas today is a very poor quality in my opinion and I’m more inclined to believe that it is more to blame.
think it was the product aas it has nothing in it to damage your engine.
Used it on a 2009 Escape. Two injectors burned.
When you use a fuel or engine cleaner where do you think any of the debris goes. If you have high mileage you probably have carbon build up. When you try to clean it by running it you cause more problems if you even had any. You can cause leaks to start partials to be embedded into bearings cause particles to clog the injection system. Just look for top tier fuels.
I agree with the other gentleman,no way did Lucas cause 4 injectors to fail. Why only 4 & not all of them? No way-period.I owned man Vetts, great car when all is well, but just like a woman- sort of temperamentall. They seemed to have a mind of there own, no reason, I am aVett so I drop 4 injectors. Reason, oh heck lets blaim it on Lucas. Female/Vett logic. Makes sense to me.
you my friend are full of s@#t what you are claiming is total improbability the injectors were gone at the start and you’re looking to blame something or someone for your inability to repair the issue correctly in other words you are a nitwit
Hi, I accidentally put 1 Litre of Lucas Upper Cylinder Lubricant into my 80 Litre Diesel tank.
My partner said that I’ve stuffed the engine by putting to much in as it’s only supposed to have 100ml or something.
Please tell me I haven’t broken the car?
There should be no damage. The engine might run a bit poorly at worst, but that’s about it – if even that. I think you mostly just wasted the product. :)
I think this problem would be solved if they would recommend amounts on their container, you have to do the math to get the recommend amount, 128 oz per gal. treats 400 gal. 128/400= .32 oz per gal. of fuel, the most likely mistake is 400/128= 3.2 oz per gal. I made this mistake, the auto parts store also made the mistake when asked what was the recommend amount per gal.
It says on the container (at least the 32oz container) 3oz per 10 gallons
I have 2 of the small bottles I refill with the gallon jug and keep one in my Lexus and the other in my wife’s Highlander. It saves me a ton of money versus buying the small bottles individually. It takes the guess work out of how much to use. I put one small bottle in at each fill up.
I have been using Lucas for many years,buy it 4 cases at a time in gallon bottles, use old little bottles to measure & Cary with me,also in quart bottles. Surprise, it gives the ratio on the bottle. 1 quart to 100 gallons, small bottle to 1 tank up to 20 gallons. Works for me.
Chloe, it’s been over a month. Did you run it out and how did everything turn out? Curious cause I went stupid and just dumped 3 quarts into my 100 gallon diesel tank for my 2000 Cummins ISC. Wondering if I should drain it or let it run…
It will not hurt it one bit. I do it a lot on my motor home? YOU WILL NOTICE better mpg & les noise. I would not do this when it’s extremely cold( below 15) , it might jell- not sure. But when warm, go for it- I do.
Run it.I double the stuff for my diesel many times it just gives it more lube with the crap diesel we get sometimes. You might even notice a slight performance edge. Many Ford guys put outboard oil in their diesels & claim extra mileage. Don’t worry, you didn’t hurt a thing,may even help, just cost a little extra.
Nah.. I’ve used Lucas on everything I own and purposely over treated a couple of my diesels. I mean way over treated. Lol. No damage whatsoever. Unless your vehicle already had a problem that would lead to failure of any kind. But rest assured it would not be caused from the Lucas product or over treatment.
I have used Lucas in all my vehicles,gas & diesel for years. I do not care what all the experts say. I hav3 accurate records- Lucas does improve mpg. If using very good fuel, it does not help much. But if using fuel with ethonal it helps at least 4 to 8 %. I personally add a bit more than the recommended dosage & can compute the additional mpg along with noticeable better excelleration. It jumped my new E class Mercedes from 39 to 42 on the #1 diesel I ran on my last winter trip. Ran 200 miles, added Lucas & continued trip. Same speed,conditions,& toll reds.
Same speed, conditions, & toll roads!
Was it also in the same direction?
When we go to our daughter’s house we get 42 mpg on the way there but coming back home on the same route and the same day, we get only 35 mpg. This happens consistently. Why? Altitude. She lives at a lower altitude; thus it is more downhill going to her house and more uphill returning home.
Can I use it on half a tank of gas I normally don’t let my car get below half and I’ve been getting crappy gas mileage lately. I have a 2002 Honda CR-V
I used Lucas Fuel treatment on my 2003 Silverado 1500 frequently and had success with better mileage and smooth running. Added 3 oz to my 2012 Ford F150 EcoBoost 3.5l engine and mileage went immediately from 20/21mpg down to 14mpg. Did I damage the engine?
Well the F150 Eco-Boost is turning out to be a pit of problems anyway after they are starting to get some real world miles on them since 2011
If I had one I would sell and run run run
I put 5.25 .ounces in my 4.6 crown Victoria, engine idles rougher than hell but put the crown victoria in drive and it runs real smooth, what happened please reply Gronenthal57@yahoo.com.
1992 crown Victoria LX.
You are NOT supposed to use any fuel additive in the Eco Boost engine whats so ever and this was told to me by my Ford Dealer when I bought my F-150 my Eco Boost runs great
Not sure what to make of that. Some brands of gasoline contain more additives than others right from the pump so do they tell you which brands to avoid?
Who told you this some numbskull salesman?
i believe fuel additives won t hurt my ecoboost but my check engine lite came on fuel injector fuel rail .lucas fuel injector cleaner can help also help fuel injector o rings
I doubt if you damaged the engine. Were you using the same fuel? I.e. Brand etc. MyFord is real goofy or picky. Sometimes for no reason it does what yours did. Mpg jumps 3-5 .,the only thing that I know effects it is temp,humidity, & at times the gas( more or less ethonal) I keep super records,spoke with a Ford engineer, he agreed with me on my facts. If I get good fuel= little difference. If I get a load of crap with lots of ethonal & add Lucas it I proves my mpg. by up 9%. Keep using Lucas, but in your turbo engine use tier 1 premium fuel. Trus t me, you will tell the difference.
what would happen if I put about 6 oz upper cylinder lubricant into the engine oil by mistake.
Don’t do that.
More than likely you would not notice any difference. 6 oz. in a 5 qts. is a very small percentage. I would not recommend doing it, but running it a few hundred miles might even help by cleaning up with the detergents in the additive. After all, it is a lubricant, most modern engines spec 5W-20 oil, so the small amount you added should not be an engine killer. I am assuming that you did not add a strong solvent, like sea foam, if so drain asap.. If it was Lucas, no problem.
Is Sea Foam bad? My dad uses it and suggested I use it in my 2016 Tacoma. Not sure if I should or not. I’m thinking about trying the Lucas product in my fuel tank.
