"My cars are now able to be used and are no longer just curiosities destined for a museum. I am enthusiastic about this product and I have no hesitation in endorsing it."
"The impressive aspect though was that at the end of the race when the engine was shut down there was no increase in temperature or overflow due to expansion. A distinct change from other coolants we have used."
"I would thoroughly recommend Liquid Intelligence 115 Synthetic Coolant to anyone having overheating problems, It's solved mine!"
Used and Recommended By James Brock (Brock Race Engineering)
"I am a big fan of Liquid Intelligence 115 waterless coolant…"
"I recommend using Liquid Intelligence 115 for all high performance engines."
"I TOTALLY BELIEVE that this is the coolant of the future"
"At Carlton Dry Honda we only choose to use what works and with the data we have collected during testing and racing this season we can confidently say Liquid Intelligence works."
"I have use Liquid Intelligence 115 Waterless Coolant in our bikes for years – It is absolutely the best coolant I have ever used."
"In competition conditions when many other bikes boil, I reckon I now have a serious and ‘legal’ advantage!"
"...there was no overheating whatsoever despite the same big hills and hot conditions. Good on the product… it works as claimed."
"All bikes boiled and overheated in this rough country… except mine. The only difference was that my KTM 400 had your Liquid Intelligence 115 in it."
"I have used and recommended Liquid Intelligence 115 to clients and friends for years. And everybody agrees that this stuff really works, as claimed."
"Liquid Intelligence 115 performed as advertised and totally eliminated cavitation erosion and corrosion….our service engineers have not replaced any wet-sleeves damaged by erosion since."
"The flow through the engine doubled after the treatment and the water galleries ended up pretty much spotless."
