Engine oil service kit with drain plug crush rings, Mahle filter and Liqui Moly oil.

• Porsche Cayenne S / Turbo 4.5 V8, 2003-2008

Liqui Moly Leichtlauf 5w40 is the best all-around modern synthetic engine oil we have used to date. Nearly every modern Porsche serviced by Lüfteknic in our facility in Richmond, Virginia leaves with Leichtlauf High Tech 5w40 in the oil tank or sump. Lüfteknic has seen reduced engine noise, smoother running and improved miles per gallon just from switching to Liqui Moly oils. A superb quality synthetic engine oil, made in Germany. Liqui Moly has complete control of their supply chain, from oil wells to refinement, and is one of the few major lubricant manufacturers to also produce their own additive packages; the ingredients that give a particular oil its unique properties with regards to lubricity, protection, emissions, and vehicle specifications. Due to outstanding protection against engine wear, service intervals of 5,000-7,500 miles or 1 year are possible, depending on vehicle use.

Liqui Moly MoS2 is an exceptional product. Highly recommended for all late-model Porsche vehicles. It offers excellent wear reduction under normal engine operation, but especially in extreme conditions such as low / no oil pressure situations (cold start / oil loss) and high temperature and high load situations such as track day use and daily commute stop and go driving. We use MoS2 in all our modern "shop" and employee vehicles, including our 991 GT3.

We use and recommend Mahle oil filters almost exclusively. Mahle is the OEM supplier to Porsche for most applications, and quality of construction, filtration and durability are unmatched in our experience. Along with quality engine oil, a proper premium quality oil filter often makes the difference between the engines that last and those that don't. We've seen lesser-brand filters (installed somewhere else) come apart in pieces or even just fail to fit correctly enough to provide oil filtration. If you're on our site we're probably already preaching to the converted, but if you're unsure, don't be: Use a quality Mahle oil filter in your Porsche, whenever possible.
