A lubricating oil especially useful as a natural gas engine lubricating oil that has extended life as evidenced by reductions in viscosity increase, oxidation and nitration relative to current commercial and reference oils is provided. The oil comprises a major amount of a base oil of lubricating ...
Two fully-formulated engine oils containing zinc dialkyldithiophosphate (ZDDP) were tested at different oil temperature regimes during long distance, high speed field tests (15000 km and 145 {plus_minus} 10 km/hr). P-31 NMR spectroscopy was used to characterize the ZDDPs and the degradation pro...
understanding of oil degradation in a combustion engine, in particular zinc dialkyl dithiophosphate (ZDDP) deterioration and its impact on wear expressed as iron content, a field test with a passenger car was carried out, which covered a distance of 19,800km and represented an entire oil change...
The Diesel Oil Alternative. Diesel oil has been exempt from EPA regulations to remove Zinc additives so it's overall better at coating metal surfaces. The heavy-duty Diesel oil also contains detergents that clean internal surfaces. Engine builders will often recommend Diesel oil for the first oil...
The engine oil with 0.06~0.10 wt.% Sc-Ag/GN nanocomposites displays remarkable lubricating performance, superior than the pure engine oil, the engine oil containing zinc dialkyl dithiophosphate (ZDDP), as well as the oil dispersed with the single nanomaterial of graphene oxides (GOs) and nano-...
ExxonMobil introduced Mobilgard 410 NC, touted by the oil company as a zinc-free high-performance oil designed to offer improvement in piston cleanliness, reduction in liner wear and a enhancement in bearing protection. In testing conducted in extreme service conditions with both EMD and GE marine...
multi-grade oil, say a 20W-50 for weather above freezing, and a 10W-30 for snowy winter use. Generally it's better to stay away from the 10W-40s, as they have a higher content of long-chain polymers to get the 40 rating from a thin base, and the polymers are not lubricants ...
CO, HC, and NOx were curtailed on a par with pure CIME which was led by activated nanomaterial and oxygen in excessive amounts. Narayanan & Anand [21] investigated the colloidal state of emulsions prepared with water, TiO2 and its blend with plastic diesel oil (PDO). The outcomes from ...
Results obtained in more than 90 samples from 15 different vehicles have shown higher degradation rates for low quality lubricant oil formulation. This deviation can be explained taking into account factors related with lower anti-oxidant additives content and lower thermal stability that can be mainly...
rings to quickly seat to the engine cylinder walls. Break-In Oil combines highly refined mineral oil (preferred for engine break-in) with an advanced additive package containing elevated levels of zinc/phosphorus anti-wear additive to optimize wear protection during the sensitive engine break-in ...
