Recommendations
Cat does not recommend the use of multigrade oils in the 3116 and 3126 Marine Diesel Engines that use mechanical unit injection (MUI).Multigrade oils use high molecular weight polymers as viscosity index improvers. When the crankcase blowby flows through the turbocharger and the aftercooler, the viscosity index improvers can adhere to the turbocharger compressor and aftercooler core.The fouling of the turbocharger and aftercooler can cause reduced air flow, loss of power, and increased black smoke. The emission of black smoke results in buildup of soot on the transom of the boat.Note: Cat recommends the use of single grade oils that pass all API CF-4 category requirements unless crankcase blowby has been routed away from the air cleaner inlet.Cat SAEO (Special Application Engine Oil)
Note: Cat SAEO is recommended for use in Cat 3116 and 3126 Marine Diesel Engines with mechanical unit injection. 3116 and 3126 Marine Diesel Engines that begin with the following serial number prefixes are included:
(S/N: 6SR)
(S/N: 8NM)
(S/N: 4KG)
(S/N: 1SK)
(S/N: 1ZJ)
(S/N: 6MK)
(S/N: 4EZ)The factory-fill for 3116 and 3126 Marine Engines is Cat SAEO with the following properties:
Meets all requirements of API CF-4 category
Viscosity grade of SAE 30For maximum performance in 3116 and 3126 Marine Diesel Engines with mechanical unit injection, Cat recommends the following engine oil:
Cat SAEO (SAE 30)
Cat SAEO (SAE 40)Commercial Oils (3116 and 3126 Marine Engines)
Cat does not warrant the quality or performance of non-Cat fluids.
When Cat SAEO is not used, use the following commercial oils:
Single grade oil with a viscosity of SAE 30 or SAE 40 that meets all API CF category requirements is preferred.
Single grade oil with a viscosity of SAE 30 or SAE 40 with an API CF additive package and no viscosity improvers is acceptable oil.API oil category CF is obsolete. The API (American Petroleum Institute) does not license this category effective end of 2010. API does not validate the quality of API CF oils and does not allow the display of API symbol (also called API doughnut) with CF as highest claim on the oil container.Oil products that used to be licensed as API CF oil performance category and have not changed formulation are acceptable for use in Cat 3116 and 3126 marine engines.For an acceptable commercial single grade oil, consult your Cat dealer.Some commercial oils that meet the requirements API CF-4 category may require reduced oil change intervals. To determine the oil change interval, closely monitor the condition of the oil and perform a wear metal analysis. Cat S O S Services oil analysis program is the preferred method.
Failure to follow these oil recommendations can cause shortened engine service life due to deposits and/or excessive wear.
Fuel Sulfur Impact on Engine Oil
Follow the recommendations given in the "Fuel Sulfur Impact on Engine Oil" section given earlier in this Special Publication in the Engine Oil chapter.Use the single grade oils recommended for the 3116 and 3126 marine engines in order to ensure the protection of the engines and follow the recommendations in your Operation and Maintenance Manual for oil drain intervals.
