A4TDI- That's great! I think you've done well and eased a few minds, mine included. Do you think this will be well received by the folks who argued so strongly against this test?

Originally 505.01 oil also met 505.00. Now it must also meet 502.00.

Do you have a source for that info? I'm not questioning it, but it's news to me.

There is nothing special about these 505.01 oils that addresses cam lobe wear. It is all about high temp/low temp performance for 10K drains, and protecting the emissions systems, not your cam lobes. Your warranty depends on using these oils and I guess it is up to you how you want to handle that. I will not recommend anyone throw away their warranty on a rather expensive little piece of equipment. You can head over to tdiclub.com for a little brainwashing by drivebiwire and that'll set you straight!
Personally, I would bet quite a bit that Delvac 1, Schaeffer's 9000 5w-40, RTS, Redline 5w-40 etc. will all protect BETTER than 505.01 oils in a PD VW engine. At least they have stout add packs.
So you work for VW then? Maybe engineered the Pump Duesse injection system?
I mean you must have if you know the current 505.01 spec for PD's to be inadequate...wait whats that? You have no idea what your talking about, backyard engineering doesn't prove your right only ruins your credibility.
First off, VW "engineered" a terribly unreliable glow plug system, "engineered" a super duper automatic restricting intake manifold system on these cars, "engineered" electrical systems that are lucky to make it 2 years without something going haywire, "engineered" an engine that requires half the engine be disassembled every couple of years to replace a timing belt, "engineered" an entire persnickety high pressure fuel system that apparently eats cam lobes and requires special oil that was obsolete before it even came out, and you're going to tell me that VW has "engineered" an oil that without a doubt the best and only oil that can be used in these engines for maximum longevity? I don't even have to be a backyard engineer to see how many of you guys are being taken for a ride on this one.
Who said 505.01 was inadequate? Oh I am quite sure it is ADEQUATE to get your car to the end of warranty with the emissions systems still intact--just like VW wants it. I don't understand the blood war that the 5 numbers 505.01 invoke in people, and why the folks at tdiclub are so anal about it. Yes I know VW is finicky and people want to protect their warranty. Fine, can't blame anyone there.
But to believe that VW designed and spec'd this oil because it will result in maximum life of your engine is naive at best. OEMs are in the business to sell cars, and car parts. Their main concern when specifying a lubricant is avoiding warranty claims on too many cars by idiots using 5w-30 Pennzoil for 10K OCIs. Since emissions systems are warrantied, the must also protect them, which means reducing valuable antiwear additives in the oil to protect the cat. Then they do some testing on some oils that big companies submit (someone nailed it when they said "bribe" above) to get the approval on their bottle. If it works okay, they approve it, which may or may not be dependent on how much the oil co. is willing to pay to get their approval rights. My guess is VW gets royalty checks monthly from all their approval oils. Oil approvals are shady at best, and if you don't understand that OEMs are not specifying oils for maximum longevity of your vehicle and simply to cover their butts until warranty is up, then arguing with you is pointless because you've obviously bought into their propaganda.
Even the great UOAs on tdiclub from those using non 505.01 oils are met with skepticism and ridicule. All the "You'll lose your warranty, You'll smoke your cam lobes" reminds me of the little boy's mom/teacher/adults in the Christmas Story constantly telling him "You'll shoot your eye out."
I sure don't see what .01 oils have in them to make them such miracle combatants of accelerated cam wear, maybe it's German Mystery Juice? Or is it just the allure of the whole European/German thing?
Schaeffer's 9000 will never meet 505.01 because it is a true HDEO, and will never be mistaken for PCMOs like .01 oils might be. If the stress on oil is so high in a PD TDI, why do people insist that the low-add .01 oils are better? If you're protecting your warranty, fine, just say so and be done with it.

My 06 TDI has now left me stranded twice. Once, quite far from home.... In light of the "facts" as I learn them, I will not likely keep the car past the warranty period.
