There’s nothing worse than seeing a car or a truck belching out black or white exhaust smoke. Think of all the particulate matter being pumped into the air we breathe every day. This is the downside of the internal combustion engine, and while fuel standards have improved vastly over the years there are still vehicles out there that emit excessive pollutants.
Black or white smoke from a vehicle contains particulate matter (PM) which is a toxic pollutant and is especially bad for human health. It results from incomplete combustion of fuel and from oil rising into the combustion chamber and being burnt. This sort of inefficient combustion also causes a buildup of carbon deposits within an engine. In other words a clean engine will emit less PM.
How to tell whether your car’s engine is clean? Taking the engine apart is expensive and impractical. But examining a car’s exhaust pipe can be done immediately. Soot within the exhaust pipe is evidence of poor quality emissions resulting from inefficient fuel combustion or burning oil.
SOD-1 Plus works to eliminate soot from emissions in various ways.
First, the detergent effect of the esters in SOD-1 Plus cleans out carbon deposits within an engine. This prevents a buildup of oxidated sludge that damages piston O-ring performance. Good (i.e. airtight) O-ring performance prevents oil rising into the combustion chamber above the piston and igniting along with the fuel.
Second, by providing an extra layer of protective film on the metal surfaces within the cylinder SOD-1 Plus improves lubrication (i.e. lowers friction) and thus improves compression levels. This helps improve fuel combustion efficiency, which in turn means cleaner emissions.
We had feedback from a customer here in Japan who sent us a photo of a dirty tailpipe on his 2014 Nissan Fuga, which has 21,000 kms on the clock. He said he was looking forward to measuring the improvement in the tailpipe soot because he has started using SOD-1 Plus.
This feedback prompted me to check the tailpipe on my own Toyota Land Cruiser, in which I started using SOD-1 Plus around 20,000 kms ago. Sure enough it was completely clean. In the car park of my local golf practice range I checked the tailpipe of a nearby Toyota Grande, and sure enough my finger came up with a smudge of soot. This is the difference between an engine with SOD-1 Plus added to its lubricant oil and one without SOD-1 Plus.
