High or low extreme temperatures can directly impact the performance of your motor oil. When liquids like motor oil are exposed to extremely high temperatures they lose viscosity, or thin out. If this happens in your engine the friction of the moving parts will be increased and this will cause wear on your engine. Conversely in extremely cold temperatures the oil will get thicker and move more sluggishly.
Pennzoil Platinum® and Pennzoil Ultra Platinum™ Full Synthetic motor oils rely on PurePlus® Technology, a process that creates base oil from natural gas instead of crude oil. PurePlus base oil won’t “gel” in extreme low temperatures, so your engine can still pump oil even on extremely cold days. It also won’t evaporate or break down when exposed to extreme high temperatures inside your engine. The rate of the oxidation stability (the chemical reaction that happens when oxygen combines with lubrication oil) of Pennzoil Platinum and Pennzoil Ultra Platinum Full Synthetic motor oils make them ideal for today’s direct injection and turbocharged engines that run at hotter temperatures.
