As an engine wears it loses compression. The seals around the piston deteriorate and exhaust gets in behind.
Exhaust begins accumulating in the bottom of your engine. Elevated exhaust concentration is a strong indicator of poor engine health.


We’ve designed a fluid that reacts to certain levels of exhaust concentration. The higher the concentration the faster it changes color.
A new vehicle typically has minimal exhaust buildup, but poor maintenance or heavy driving can cause engines to wear out much faster than expected.

The Ultimate Engine Kit includes 3 head gasket tests along with the 3 blow-by tests. A leak on your head gasket will produce CO2 in your cooling system. The test is easy and operates similar to the blow-by test.
Although the fluids look the same they have different sensitivities to CO2. Your crankcase always has traces of CO2, your cooling system should not have any traces of CO2.
