10013 Fuel Treatment-3.78L, clear yellow

Fantastic. Engine is quieter. Smother. A lot more miles to the gallon. Amazingly put some in the mower. Starts first time. Only had the mower 1 year, it never started well. Gave some to my Son & 2 Granddaughters. They all sore the same improvement as me

Been using this regularly for 30 years and it’s never let me down. For cars with lots of miles it cuts down on the knocks and noises and for newer cars it keeps it running smoothly while increasing gas mileage and performance.

I use this in my car and motorbikes , its great , my car is diesel and motorbikes petrol , I can here the engine run a lot smoother with this and has increased the mpg slightly , it has also cleaned out my diesel engine as it used to smoke a bit when putting my foot down , and now it does not ,, 3lt V6

engine running smooth and quiet since added,now add everytime fuel up tank.

Given the increasing price of fuel, this was bought at best price online at time of purchase. This is a multifunction product, mainly cleaning diesel and petrol fuel injector jets and engines, as well as increasing fuel economy through the combustion process. If the right measured amount of additive is inserted into a full tank of fuel, after just a few miles you can really feel the difference in the vehicle's acceleration, torque and responsiveness, all of which will have significantly improved. However, in order to benefit from any resultant fuel economy improvements, it is important to then resist driving aggressively due to slightly increased performance. To maximise the fuel economy you must then drive conservatively and easy, which is difficult to do the car generally feels more lively and responsive. Recommended product.

Works well and has improved mpg by around 16% on the two tank fulls.

Even though my car has already traveled 200,000 miles thanks to this magical additive, it has almost no equal on the highway. The engine was cleaned of dirt and looked younger. But a month ago I came home with almost nothing on the cylinder, and the craftsmen calculated more money for repairs than the price of the car itself. Only 180 grams per full fill and you have no problems or stress with the engine and fuel system. I recommend it from the bottom of my heart

Genuinely impressed with this. Think I saw a vid suggesting it was good. Used in vw camper diesel and also suzuki vitara diesel. Both run amazingly much smoother and giving a genuine 10% plus improvement in consumption. The vw with 70k on the clock always felt unresponsive at low revs and looked at getting in chipped. However using this made it so much smoother at very low revs meaning changing up at lower revs, likely helps with the consumption. Even using the premium fuel from shell had little affect till I added this. Took around 4 adds to fuel but then the difference was noticeable.

Good

Excelente aditivo, a muy buen precio tanto para diésel y gasolina muy recomendable para cuando el combustible no es de tan buena calidad. Actualización 01/06/19 Llevo 3 años usándolo y es excelente, literal del rendimiento que da y performance se paga solo(uso dentro de la CDMX) muy, muy bueno.

Can't go wrong with any Lucas products, Amazon pricing is very competitive, with on-time delivery. Really saves on fuel!

Three stars means 'good'. Engine in my 2007 B180 CDI is noticeably quieter and smoother, especially idling, and fuel consumption reduced a little. Good value in a 1 gallon bottle, but it isn't practical so you'll need a smaller bottle. I bought a Lucas 5.25oz from a local auto parts store, used that, now refill it and store in a zip lock bag inside the cabin. At a dose of Lucas for every tank, I get 25 tanks from a 1 gallon and I think it is worth it. Edit, 19 August 2021: Four stars. After selling the first B180CDI, bought another, used Lucas in that and got great improvements - reduced consumption by 10%, engine noticeably quieter and smoother. Great buy!

Parece que baja el consumo y el coche va mas fino
