Just ran across this Syn was interested in doing as a SRT does here is a brekdown of its oiling system much different from ours but at the end the oil filter it uses will work on ours and sounds like if you run thicker oil it could be a good one to use.................................The SRT® 6.4-liter HEMI® engine, standard in 300 SRT, Charger SRT, Challenger SRT and Grand Cherokee SRT vehicles, is equipped with a severe-duty oiling system developed to maintain pressure under extreme conditions. SRT engineers added a higher pressure oil pump relief valve, relying on a stiffer internal spring, to help maintain higher oil pressure under all driving conditions.
Oil pickup tubes have been shape-optimized to be efficient under a wider array of operational parameters. To help keep temperatures under control, while operating under intensified load conditions, oil squirters have been added off of the main oil gallery, with the specific intent of lowering piston temperatures.
Additional oil flow through the piston-squirters requires higher oil pressure within the engine’s block. This incremental oil pressurization specific to SRT applications yields efficiency benefits a casual observer might not anticipate.
“Higher oil pressure is about more than sustainability under extreme conditions,” said Kraig Courtney, 6.4-liter engine supervisor. “Increased operational oil flow at a higher level of pressurization is an efficiency enabler, as well.”
Oil pressure management is critical to variable camshaft timing calibrations and variable displacement applications.
“Variable camshaft timing is a ‘three green’ technology,” says Courtney. “It improves fuel economy, reduces part-throttle emissions, and provides improved engine response when the light turns green. It’s a win-win-win technology.”
Higher oil pressure also enables efficient cylinder deactivation, delivering fuel economy benefits in steady-state cruising conditions.
When an SRT owner takes their vehicle to a driving event with the specific intent of exploring the far reaches of the performance envelope, they can rest assured that the 6.4-liter HEMI engine will sustain proper oil-pressures in extreme cornering conditions. For track-day use, SRT engineers suggest using the SRT oil filter (part number 05038041AA). Originally designed for Viper applications, it works great with all Chrysler V8 engines. The SRT filter features a higher differential pressure bypass valve and reduced pressure loss across the filter element
“Modified oil pickup tubes, the piston-squirter jets, and the oil pan work in harmony to keep operating temperatures down, and efficiency up, at sustained higher oil pressures,” added Courtney.
The SRT 6.4-liter oil pan is die cast aluminum to save weight and improve heat dissipation, featuring baffles and precisely managed drainage to prevent oil sloshing or starvation under hard cornering situations.
What does it all mean? Push it hard under closed-course conditions to experience peak performance and response. Or set the cruise-control button and cruise at peak efficiency levels. It’s your choice. No pressure.
