The lack of any significant fuel dilution in UOA's (used oil analysis) with B10 to B20.

OK, but I believe that cylinder post injection improves fuel economy since it's still done during the latter part of the power stroke. Some is converted to energy and some remains to go downstream to the DPF.

Injecting fuel directly into the exhaust system is 100% wasted fuel.

But if it means the difference between B5 and B20, and continued manufacturer supported 10K OCI, is it worth it?

Doesn't the owners driving habits depict how much Biostays in the oil? My understanding is that the only reason bio diluts the oil is that it doesn't evaporate as quickly. Longer the run times at highway leads to more of the bio to dissapear.

So I think it'd be wrong to make a blanket statement that because of a couple UOA show there's no problem running B20 for someone that does short jaunts and doesn't eat up massive amounts of highway.

The average person doesn't do UOA, but I'm thinking the average person commutes less than 20 miles at a time.

I could be compleatly wrong by this thought though.

Does anyone know if the new biofuel mandate in Germany (E 10) also includes biodiesel:

Maybe 10, not 20. They'll stay as close to the highest mandate as possible.
Ford uses post-injection, just like VW.

GM uses a ninth injector, though.

Ooops...meant GM. Ford does have a "dilution sensor".

The one I referred to above was not far off the 36K and way below the 60K PT warranty threshold. Both of these incidents were posted here by me.

So let me get this straight. Let's assume you came by my dealership and purchased one of my supposidly and totally prime pre-owned TDIs and I specified to you that I replaced the TB assy., along with servicing everything under the sun. You take delivery and shortly down the road the vehicle quits on you and it ends up being a timing belt assy. issue. After investigating the failure, you discoverd that I used some Chinese knock-off roller or tensioner resulting in $3K to $4K of engine damage. Would you give me a pass similar to the pass you want to give VW? Somehow I don't think so and therefore I would most likely be the scum of the earth in your eyes and you would most likely be posting your experience here on this venue until the fricken cows came home.

Or how about this. Let's assume you continue the routine of only using the Shell station you claim to use each and every fill up and a couple thousand miles down the road or 12K to 13K on your odo, you experience an HPFP failure. The vehicle gets towed into a dealer that hasn't had several HPFP failures and this other dealer immediatey claims fuel contamination or mis-fueling and therefore denies coverage. Would your total appeasment attitude all of a sudden mysteriously change at this point? Or to make it more realiatic, let's assume you just turn 36,001 miles and kaput! You then take it to McKenna and they totally deny coverage due to the vehicle technically being out of warranty and even the area rep refuses to capitulate. I think at that point you would be singing a totally different tune, or would you? I mean afterall, a $6K to $10K out of pocket repair bill won't kill you, eh? You gotta love this poop! Later!
Ok, I stand corrected on the car, but that dealership still covered all the HPEP failures under warranty. That is worth something. That is an honest dealership that you can build a relationship with. They took care of all the VW TDIs that had a failed HPFP pump under warranty.

I love situational games, so I will play. First, I will only tow my car to McKenna. I have a 100 mile unlimited towing from AAA. I also have my own truck and trailer. So I can tow my car to where ever I want. So should that situation arise, I have MANY options. I do not even need VW to tow my car for me. There once was a time when owners did not have roadside assistance.

Second, you also seem to ignore that I also have mechanical warranty from Geico that covers the HPFP failure. So in case VW does not cover it after 60,000 miles (some say HPFP is covered under 36,000 and some say under 60,000), I have Geico to take care of me.

So as you can see my friend, I have it covered. I am not the sort of guy to live much to chance. I am not the sort of guy to ***** and moan and cry over spilled milk. What happend has happened. I bought a first year production car (something I rarely do) and now I have to live with it for a few years. I will take all the pre-cautions needed and continue to enjoy the car.

Interesting. Just wondering how dealers would react to it.. send you a letter saying "your car is broken, it will need a new $2000 DPF every 30k miles".... lol.
I personally would love a B10 or B15 mandate, as long as the filters and NOx trap etc are ok with it. Which I'm sure they will be (and are).
Very interesting.

I'm glad you're well covered. Just that the average buyer isn't. And when they are concerned over it it's not cool to blame the victims and mock them. They are entitled to be provided for by VW. They don't have your wealth. They bought a VW because VW purports to be affordable by them. So the question may be why don't you buy a Beemer and leave us alone.

In the US, I would expect most people will have Comprehensive Insurance since the car is new and collateral for a car loan. My Comprehensive policy with Nationwide covers catastrophic engine failure not covered by warranty such as from misfueling, road debris taking out an oil pan, etc. (less my deductible). You should check your insurance policy, that's all I did (i.e. I didn't add the coverage)

If comprehensive covered this wouldn't someone have made a claim? Even if it did, it's the same difference since rates would go up if VW scammed customers into dumping their warranty responsibilities onto customer's policies. And let's not trivialize deductibles.

I would much rather VW covered it under warranty than going to my insurance. In addition to the $250 deductible, they would also find a way to raise my rates to reflect paying for the $8000 - $10,000 repair.

There has been no need to file under Comprehensive. With the exception of maybe 1-2 HPFP failures reported on this site (that I am aware of), all failures have (eventually) been covered by VW warranty.

I may be wrong about this, but as I recall both denials were due to gasoline mis-fueling and the repairs were covered under Comprehensive Insurance after the warranty denial.

I have little concern about being covered under warranty. My concern is driving the car out of warranty.

I would love to take the car to 300K but I cannot in good conscience risk losing all value in the car to a pump failure. I also wonder if the risk of failure increases as the pump ages.
