webrest Posted 16August, 2014 Report Share Posted 16August, 2014 Has anybody out there priced the Classic Oil that Porsche is supplying themselves. I probably should say, having repacked for them . Love to know what they think it is worth. Link to comment Share on other sites More sharing options...

smule Posted 16August, 2014 Report Share Posted 16August, 2014 I asked a casual question when picking up some parts recently, and Alex mentioned 120 retail for the 5 litre tin. Link to comment Share on other sites More sharing options...
tazzieman Posted 17August, 2014 Report Share Posted 17August, 2014 I asked a casual question when picking up some parts recently, and Alex mentioned 120 retail for the 5 litre tin. At a dealer , for an AC 911 that would be nearly $300 for an oil+filter change (plus labour). Link to comment Share on other sites More sharing options...
Peter M Posted 17August, 2014 Report Share Posted 17August, 2014 I'm not convinced that it would be best oil we could use in our AC's anyway. No mention of it meeting any specifications that I can see. Link to comment Share on other sites More sharing options...
webrest Posted 17August, 2014 Author Report Share Posted 17August, 2014 I think that I had a look at the specs on an American site a few months back and the ZDDP was OK but who is going to pay outrageous prices like $120 for 5L's. Repack of what? Well Max that is the $64 question. I do not think Porsche will have their own chemists working through the night mixing up their own brew though. They are getting from somewhere.

Guest Harold Posted 25September, 2014 Report Share Posted 25September, 2014 To many, the cost of service is unremarkable. Link to comment Share on other sites More sharing options...

tazzieman Posted 25February, 2015 Report Share Posted 25February, 2015 Based on that , BMW will send him a lifetime's supply of their stuff , whilst porsche will send their resident Alsatian. Link to comment Share on other sites More sharing options...
Peter M Posted 26February, 2015 Report Share Posted 26February, 2015 Oh I wish my life was so simple! Good oil contains ZDDP and a bad oils contain less.Good oil has a high TBN and a bad oil is less. The truth is much more complex and we will never know what is the absolute "best" oil as there is far to many variables involved. In order of importance, I think cam lobes are best protected by good quality, extensively tested, clean oil that keeps the cam lubricating jets clear of varnish and other obstructions, a minimised number of starts (particularly cold ones), maintaining correct valve lash clearances, regular long runs to keep the lobes covered with a film of oil to protect from corrosion pitting and to evaporate the moisture build up. Also replacing the oil often enough to maintain a healthy TBN to again minimise corrosion also helps. I don't lose sleep about a couple hundred parts per million of ZDDP here or there nowadays as the above is far, far more effective in protecting my engine. BTW: Thanks for posting Tit as I was keen to see a VOA for the Porsche branded oil.(Porsche Classic Oil 20w-50 contains 883 ppm of Zn for those who are curious. I'm sure it contains a whole lot of other more modern supplementary anti-wear compounds that the conventional oil analysis don't or can't detect.)

Peter M Posted 14March, 2015 Report Share Posted 14March, 2015 Came across a bit more info on these oils from a PCA Tech session presentation by a couple guys from Porsche Classic:http://rennlist.com/forums/993-forum/859939-feb-15-pano-two-interesting-993-oil-comments-5.html#post12081537It answered two burning questions I had:Why no industry rating such as API SN or ACEA B3/B4?Doesn't need to be as it is made specifically and recommended for AC Porsches by the manufacturer so there is no need.Why 10w-60?Because that's the grade most enthusiasts are using and they didn't want to confuse them! Mmmmmm, I wonder if that was a suggestion from the marketing department?(There is also a fairly lame Youtube interview with these guys on the PCA channel as well.)I'm happy with all that and it doesn't change my buying whatever is suitable and readily available at Repco or Supercheap Auto.

Stew F Posted 15March, 2015 Report Share Posted 15March, 2015 From www.usatoday.com - 16 June 2014. "Today's mileage-oriented, lightweight motor oils don't cut it in old, air-cooled Porsches. So the German sports-car maker has developed its own lubrication that it says is better for classic Porsche. The heavyweight ratings on the Porsche oils will seem almost obscene to those who are married to today's fuel-economy oils. 20W-50 for 356, 914 and 911 models up to the 2.7-liter G-Model 10W-60 for flat-six engines from 3.0 liters to the 911 (type 993). It's $12 per liter, which is close to a quart.. Modern synthetic first-grade oil, such as Mobil 1, is about $8 a quart. Modern oil ratings are sometimes as light a 0W20. The lower the numbers the easier the oil flows, especially when cold, and its lower friction means the moving parts of the engine can move more easily, boosting mpg. But such oils weren't around when the older, air-cooled Porsches were designed. Porsche began switching to water-cooler engines in 1998, but engines before then need heavier oil to help keep them cool and reduce oil consumption, Porsche says. Porsche says the oil also is designed to avoid damage in engines that are started and run only now and then, as when an owner fires up for a weekend jaunt. Engines that sit collect moisture in the oil and that can be damaging. Heat from the engine drives off the moisture, but in air-cooled Porsches, the company says, the key is the chemistry of how the oil reacts to the moisture and possible engine deposits. Porsche says the oil is made for it under contract, but declines to name the supplier." Probably formulated by someone like JB German Oil. Link to comment Share on other sites More sharing options...
