Noticed improvements

I have noticed a increase in response when needing power since using the Decarbonizer. My fuel consumption has also improved (decrease in L/100kms) according to the computer. That's a win. Still needing more time to run the Decarbonizer and hoping it helps resolve my DPF issues I have once it's given a good ol clean out.

So impressed with these products

Great service by Matt in getting me the pack of AW10 oil modifier , fuel system lubricant ( cant remember its name ) and the FTC decarboniser . Each year we come back to Australia and do our normal Xmas drive of around 5000 kms to see friends and family . I have a 2007 RangeRover 2.7V6 Turbo with 215,000 kms on the clock . Normal fuel consumption is around 10.2L/100 kms . Added all the additives in and just completed another 5000 kms .. Average fuel consumption dropped to 8.8L/100 km . Driving wise like WOW.. engine feels smoother and far more pickup going up hills , its like someone added another cylinder or two...... really noticed the difference in responsiveness and much smoother when cruising..... great products .... just love it when you get what you paid for and more. Thanks to Cost Effective Maintenance .
