      Agreed. College is just a tool to help you realize how to learn/teach yourself to do something.

      Several years ago at the Porsche school in at Barber Motorsports Park, they had a fleet of all sorts of Porsche cars, but most predominantly are the 911 and the 911s they use for the track sessions. During the session I was there, several Mobil One guys were at Barber meeting with the Porsche guys. In summary, the 10,000 mile interval that Mobil One recommends for Porsche (which Porsche subscribes to in their manual) was said by the Mobil One guys to be short and than 15,000 was not a problem nor an issue with their synthetic oil. In fact, the follow up comment was if you do it every 3-5,000 miles, you're just wasting your money.

      I put 218,000 miles on my 2004 Touareg. While it went against what I had grown up doing with oil change internals (5,000), i stuck to doing them every 10,000 miles in the Toaureg based on the Mobile One guy's comments at Porsche. I never had an issue.

      Moving forward, with my 5 series BMW, the intervals are even longer (15,000) AND covered under the normal maintenance plan by BMW.

      So, the bottom line is that conventional wisdom about frequent oil changes that may have been good in the past 20 years is no longer the case today with the synthetics that are run in the higher performance vehicles; especiallly the european vehicles. Despite the photos in this thread, I think it is reasonable to assume that there's a lot more to the story that the vehicle owner (or past owner) did that we simply don't know about that may have resulted in this situation.

      Assuming the oil meets or exceeds the manuf spec for that specific vehicle, I agree. My 2006 E-class for example, could use several Euro-labeled oils, but none of those were reasonably available in my area of the US. The only US oil that satisfied the extended oil change interval for my engine was Mobil 1 Formula M. It is an oil spec'd for selected Mercedes diesels only, no other car manufacturer uses it. Needles to say, it was classed as a specialty oil around here, and only carried by a select few. So it is clear why a certain group of owners might rationalize that any old synthetic will do. Same with VW. It's not who makes the oil that's important, it's what's inside. Meeting/exceeding the 507 spec is the key to the extended oil change interval.

      I have 133,000 mi. on my 2004 Touareg purchased new in 2004. I have the oil changed every 10,000 mi. and it never uses a drop. When a dealer changes the oil they put a sticker on the windshield for the next oil change to be at either 3,000 mi. or 5,000 mi. They don't read their own service manuals. They also always fill all the tires to 41 psi. Go figure.

      I thought your tires on a touareg should be around 41psi

      I have oil analysis done in my TDI and a 10K OCI is a reach. The factory fill was almost depleted of wear additives at 5,500 miles. Fuchs Titan GT-1 was still serviceable at 7,000 miles, but I would not have carried it out beyond that. I think none of the 507.00 spec oil are robust enough to last the recommended 10K OCI.

      Something's just not right here. There's got to be some other variable that's not being taken into account. It simply makes no sense for a car manufacturer to specify a specific oil spec , then not being able to meet it's own recommended service interval. And this engine's been around for at least 9 years. It seems like this issue would have surfaced before now.

      My 2006 E-class diesel had such an extended interval, no problems whatsoever. The oil in my Touareg was just fine at the initial 10k service. I'm buying a new Porsche diesel that has a 20k oil change interval when C30 spec oil is used. I'm pretty sure their gasoline engines now have the same 20k interval on A40 oil.

      I'm just not buying that this is a global VAG problem, we're missing something.

      I'm a cynic and I think it's just corporate bean counters. I think VW offers free maintenance for the first 36K because BMW offered it. Money is saved if the customer does 3 rather than 4 or more changes. In order to make sure any DPF service doesn't fall within the free maintenance period, they spec low SAPS oil. 5W-30 vs the 5W-40 some MB spec oils provide is just to eek out one more percentage point on MPG.

      What people that know about oil have told me is that the low SAPS formulations caused the blenders to stop using the cheaper, but very effective, additives. 507.00 spec oil is very good oil, it is just asked to do an awful lot hindered by a narrow allowable additive window. I don't think you would actually harm your engine by running a 507 oil on 10K OCIs, I do think your engine would have a higher level of preventative wear.

      So it might only last 300,000 miles instead of 400,000.

      Which makes no sense as the requirements are the same in markets where VW does NOT offer included maintenance.
      The reality is that many, many folks (even across the pond) do NOT perform required maintenance, with results as pictured above. Nattering @ various minutae is pointless - follow the schedule, you'll be good, and no, you won't keep your current vehicle to 500K miles...

      Mk2Reverie, I certainly don't fault you for trying to help others on here. Heck, that is what this place is all about.

      But kind of hard to make such a claim knowing very little what the last owner did to your car. We all have our lapses or memory and who knows what they truly did as far as maintenance without any record.

      At $110+ an oil change (04' V8 in an expensive city) I will be sticking to the 10K full synthetic, until someone convinces me otherwise.

      Safe driving.

      I hate to say it but the type of vw owner who takes their car to a indy shop is mostly likely to skimp on oil changes. The vr6 and v8 are not sludge prone engines. They can easily do 10k on a vw502 spec oil.

      I would rather take my car to a reputable indie. They may not have the the most attractive waiting areas if any but as a business owner they have more on the line than an employee at a dealership. I've had some dumb $h|+ done to my car at a dealer.

      FYI - you need more than just syth oil. you need to use the proper SPEC of syth oil.

      702.11 or greater or syth oil specifically for diesel or turbo applications. if you use the proper spec of oil for the intended use (gas or diesel, or turbo, etc) then the 10K intervals is not an issue.

      Does that mean I have to go to the dark side for oil?
