Together with the different temperature zones which are characteristic of air-cooled engines, this means that the oil needs a high 'hidden' performance reserve.Р”Р„ compact and lightweight engine design means that the connecting rods will be short in relation to the piston stroke, which in turn means high lateral piston forces and correspondingly high demands on the lubricating film stability of the oil. The traditionally high power output per litre of the engines also results in high compression and high pressures. The larger oil volume firstly entails a longer oil heating time, and secondly calls for optimum cold running behaviour. The thermal load is higher than in water-cooled units, for example, which means that the engine oil has to work harder to cool the engine down. The engine is the heart of each and every Porsche, and air-cooled flat engines place particular demands on a lubricant.

The Porsche Classic Motoroil comes in two different versions: 20W-50 for all 356, 914 and 911 models up to the 2.7-litre G-Model and 10W-60 for flat-six engines from a displacement of 3.0 litres up to the 911 (type 993). Its operating behaviour and lubricating properties were put to the test in extensive laboratory-based tests and practical trials. In collaboration with the Porsche Development Centre in Weissach, the new engine oil has been developed by the Porsche Classic experts with the specific aim of meeting the demands of the 356 and 911 models, including the 993 model range. And if it says Porsche on the label, then you can be sure that there is Porsche inside.

Just in time for the start of the season, Porsche Classic is launching its own engine oil for air-cooled flat-four and flat-six engines: the Porsche Classic Motoroil. Scroll down for the official announcement.

Even if you don't have an air-cooled model, it might be worth buying a can for the cool design. The 10W-60 goes for $15.55 for a liter and $68.68 for five liters, according to company spokesperson Calvin Kim The 20W-50 costs $11.83 for a one-liter container and $51.27 for a five-liter bottle. So this formulation is more alkaline that normal to neutralize acids that they build up and corrode components.Р”В«oth weights are available now to order from PorscheР”Вealers. The company also knows that most owners aren't driving their vintage cars everyday. The new oil is specifically designed to work with the old-fashioned materials found in its classics. They are fantastic at sopping up debris, but those deposits are often holding archaic seals together. The company claims that the air-cooled engines have different heat demands than traditional, water-cooled units, and this oil is made to meet those requirements.Р”Р„ccording to Porsche, modern, synthetic oils are sometimes too effective when it comes to old engines. Porsche Classic is helping out, though, by introducing its own brand of motor oil for the demands of the company's vintage, air-cooled engines.Р”Вeveloped at the Porsche Development Centre in Weissach, Germany, Porsche Classic Motoroil comes in two weights РІР‚вЂњ 20W-50 for the 356,Р”В©14 and 911 models up to the 2.7-liter G-Model and 10W-60 for 3.0-liters-and-up engines through the 993-chassis 911.
