Small tablets. Considerable impact.
What drivers noticed in everyday use:
"We've been using car pills for about six months and we are very satisfied with them.
The fuel consumption has dropped by around 7%. And this is even though previously we were using premium diesel fuels about half the time at petrol stations. It also seems to us the engine produces less smoke than before.
We enjoy the ease of dosing the pills when fueling the car so we can only heartily recommend them."
Honza - Ford Mondeo, 2.0-litre diesel
Another driver described their experience after approximately 450 miles:
"I have first results after approx. 450 miles. The car runs substantially better, engine sounds smoother, valves don't knock and are quieter. The engine has a more refined operation overall and my impression is as if it is 3 to 4 years younger - runs smoother and noticeably quieter, almost as if it was new."
"Testing the car further because it looks like the lowest fuel consumption ever. I drive in a sport mode and despite that I still have 625 miles per tank (standard for economy driving) which is perfect considering my sport mode driving and regular heavy traffic in my area."
Michal
"My feedback:
PROS:
+ noise reduction + vibration reduction
+ it seems like the engine runs smoother + reduced fuel consumption after second fuelling
CONS:
- because of the safety lid on the tube, its opening may be tricky for some"

long-term, real-world experience:
Are CarPills safe to use in cars and what have we noticed after years of use?
We’ve personally used CarPills in our own cars for close to a decade. Customers have also shared experiences of using them over several years, across different vehicle makes and engine sizes.
During our own use, we have not seen adverse effects in those vehicles, nor there were any in customer reports.
Measured comparison
What does the laboratory evidence tell us?
E&S Environmental Services analysed paired customer-supplied fuel samples: one untreated and one treated with CarPills. The reported cetane number was higher in the treated sample.
Cetane describes how readily diesel ignites under compression. This means diesel starts burning sooner after injection, which can support smoother running and, in some engines and conditions, better fuel efficiency.

1. Add before refuelling
Use one tablet per up to 40 litres of fuel.
2. Continue your normal driving

3. Record what changes
Note how the engine feels, the distance travelled and the fuel used. Compare several fill-ups under similar conditions.
If you notice lower consumption, subtract the cost of the tablets when working out your net saving.
