Caterpillar D11R Low Engine Life and High SOS solved by FTC / FPC Combustion Catalyst (Decarbonizer) from Cost Effective Maintenance

As with some other engine types, Caterpillar D11R low engine life and high SOS oil contaminant levels are due to bore polish, a condition which is solved easily by the use of the FTC/FPC Combustion Catalyst (Decarbonizer) from Cost Effective Maintenance .

Bore polish is caused by excessive build-up of hard carbon above the piston top ring. This carbon will then start to rub against the cylinder liner to cause severe wear, which in turn would lead to low engine life, excessive oil use, and high SOS oil contaminant levels. Oil soot, oxidation and wear of metals also increase.

Catastrophic engine failure (piston seizure or exhaust valve failure) becomes more likely as deposits build. Of the Caterpillar 3500 Series engines, D11R low engine life appears to be the more frequent complaint. The FTC/ FPC Combustion Catalyst (Decarbonizer) has solved numerous engine carbon problems for over two decades, including severe bore polish. It simply works by safely burning away hard carbon from combustion and exhaust spaces, including pistons, rings, valves, ports and turbochargers.

The untreated engine achieves 4189Hrs and is clearly not fit for further service, whereas the FTC/FPC treated D11R has longer service life, and can easily achieve several thousand hours more. The FTC/FPC treated D11R engine has no cylinder bore polish usage and piston skirt wear, and has decreased piston ring face wear, piston ring groove carbon, piston top land carbon, exhaust valve carbon and exhaust valve pitting.
