The minute I bring up a Skoda it cannot be about the US. You should know that.Topic is diesels in the US. You were apparently trying to say that the diesel would be able to go a lot longer between maintenance stops in such conditions, when VAG says otherwise about diesels in such conditions.
Not likely - the included 'free' maintenance for them is at 10, 20 and 30K and nobody's going to be doing it more often than the 'free' intervals.Besides, even the 10000 miles VW USA appears to mandate for its TDIs probably is much longer than most US drivers keep their oil in their car.
Apparently that's more than twice the distance the average US driver keeps their oil in the car. Apparently, many many people are "going to be doing it more often".Not likely - the included 'free' maintenance for them is at 10, 20 and 30K and nobody's going to be doing it more often than the 'free' intervals.
Do you have a newer study showing that the slow-changing US car population has in fact more than doubled their habitual change intervals?That study you cite is more than half a decade old (published 2007, data in study much older). Much of the vehicle population has turned over since then and the majority of those cars have the new lower weight oils with extended service intervals. Most cars on the market now have 10K service intervals.
As of last year, the average vehicle age in the US was 10.8 years. It was about 9 at the time the study you reference was completed.Do you have a newer study showing that the slow-changing US car population has in fact more than doubled their habitual change intervals?
That's not what I asked you for.As of last year, the average vehicle age in the US was 10.8 years. It was about 9 at the time the study you reference was completed.
The extended oil drain intervals came in in 2001 with the API SL specification. Cars of that year and newer mostly have the 10K oil change interval here in the US.
2013 - 2001 = 12 years. 12 years > average age of US vehicle fleet. Means the average car in the US is very likely to have an extended oil drain interval.
All it says is "40% of people are putting off maintenance to save cost". It doesn't provide any numbers on when they actually change their oil. Here's an example: If a driver still has his job he changes every 3k. Now he loses it and instead flips burgers, so he puts off the oil change until 5k. Going by what the study says, that's entirely within their scope.Further, if that weren't enough, recent studies show that at least 40% of people are putting off oil changes and exceeding the specified oil drain interval. http://nj1015.com/drivers-putting-off-maintenance-to-save-cash-study-shows-audio/
Too bad. We all have these little disappointments in life. Especially since the study you linked doesn't show the stats for the general public at all - the study said, and I quote:That's not what I asked you for.
To investigate barriers to HE filter technology use, staff mailed surveys to 1,987 fleet managers. Two hundred and sixty-two surveys were returned (a 13 percent response rate) including responses from several State agencies, and other public and private fleet operators representing a broad spectrum of vehicle types and sizes.
This data is based off of fleet managers' actions, not the general public. Fleet maintenance is on the average, far more meticulous and regular than private individuals' maintenance. Fleet managers usually use the much shorter "severe service intervals" listed in the manuals if they don't have an even more paranoid regimen worked up already from an earlier era. It's unheard of for a fleet manager to wait for the service indicator to come on. There are various reasons for this, but the bottom line is they just about always service earlier than anyone else would. My CVPI that I recently sold was run in the police fleet of a small town in Texas. They ran 2500 mile oil changes - *nobody* would do that in the private sector.Four State agencies, two local school districts, and one local transit agency partnered with DTSC for the study?s demonstration phase.
It doesn't say they change it that early, either. It says that they're putting it off. Most people (assuming they even know there's a set interval, which many don't any more here) now change at the recommended extended interval. If that's what they're doing, then they're blowing off the extended interval. This would be borne out by many of the incidents of engines ruined by oil gelling due to people blowing off the extended interval by a bit. (Not the ones caused by bad design or bad specifications, though.)All it says is "40% of people are putting off maintenance to save cost". It doesn't provide any numbers on when they actually change their oil. Here's an example: If a driver still has his job he changes every 3k. Now he loses it and instead flips burgers, so he puts off the oil change until 5k. Going by what the study says, that's entirely within their scope.
There are exactly three diesel car types available in the US market between five and fifteen years old. Note - cars, not trucks.I'll never understand why you people insist on putting "a new diesel car" into the argument. There are used ones too, you know...some very cheap and good deals. And suddenly you're doing 50+mpg in a car that cost you not all that much... Exactly what I'm planning in the future. Diesel is always a bit cheaper here (not the case in the US, I know) and a hatch with a 1.3 or 1.9 turbodiesel gets awesome mileage on long trips in 5/6 gear; exactly what I mostly do. Chiptune it and you have a little rocket on your hands. It's just win all over the place.
But I know what responses await me after my thoughts, so...fire away. :lol:
Oh yeah, and there are NO 2008 VW diesel cars here. 2008 was a skip year because of new EPA and other environmental regs. Their TDI wasn't ready, so for MY 2008 your single diesel engined car option was the E-class (which briefly had a hiatus as well). Cuts into the supply even further.Maybe I should have pointed out that I had all of you in mind, not just the US. But I see your point, I didn't know the situation is THAT pathetic. Sucks balls, to be honest.
True, the service intervals tend to be shorter - my Pug was 20,000 Miles recommended for Petrol and 12,000 for the TDi diesel engine I ran.Another problem for US diesel acceptance is higher maintenance costs for the diesel. The oil change prices alone are considerably higher for most diesel vehicles, even given equivalent size engines just to start. Other maintenance costs are also higher in terms of parts cost, specialist labor, and diesel exhaust fluid.
