Re: Rotella Oil Question
Another thing is that the real tough enviromental rules only affect 10w30 and lower viscosity...the diesel oils isnīt affected in the same way by law.
The lowered amount of ZDDP would work much better if there wasnīt a ton of detergents added to the oil to keep catalytic converters and other eco systems clean. The detergent destabilize bearing materials and wash away antiwear additives....all in the name of a greener planet...building and scrapping a car each 7th year seems like a good plan...or.. |

Re: Rotella Oil Question
The trucks are pee burners now days with selective catalytic reduction. The phosphoric content (ZDDP) isn't all that good for them either. Diesel truck engine oil is rated differently but it also has differences in the other additives that don't match up to gasoline engine auto motor oil quite the same. It will work OK but it's not the same as auto type motor oils.

Re: Rotella Oil Question
Modern diesel engines use an additive called DEF which is a urea based fluid. It helps remove the nitrogen oxide which is detrimental to cat converters and the air we breath.

Gasoline catalytic converters: Nitrogen Oxides are produced from high compression. The requirement to reduce nitric oxides is the reason compression ratios were lowered in 1972. Nowadays, compression ratios are back up! Newer converters have a first stage that breaks down nitric oxides into nitrogen and oxygen. The first converters were not capable of breaking down nitrogen oxides. The main role of these was to finish combusting unburned hydrocarbons (incompletely burned fuel)... and to convert carbon monoxide into carbon dioxide. They relied on an air pump mounted to the front of the engine to supply the needed oxygen. Modern converters THRIVE on nitric oxides, as THOSE are what provide the oxygen to finish burning unburned hydrocarbons and convert CO to CO2. These have allowed compression ratios and power to make a major comeback.

Re: Rotella Oil Question
The diesels have several different Catalythic converters aiming for different things...
DOC(diesel oxidizing converter)-DPF(diesel particle filter)-Pea injector-SCR(selective catalytic reduction)-ASC(ammonium slip catalysts). Just to give us several bumps on the exhaust that clogs up in slow city driving.... |
