I have access to ASTM 6751 biodiesel that I am considering using using as a lubricity improver in our Golf Sport Wagen. It will be within VW's 5% mandate and I am wondering if anyone has any opinions.
If it's cheap enough to offset the reduced mpg you'll see from it, then that certainly checks off the fuel cost portion of the decision. Then you'd just have some questions to answer on oil dilution, injector deposits, dpf life, etc and if you are good with all that with no real additional benefit to lubricity, then you might make the personal decision to use B20.but if B20 is cheaper than D2, which it consistently is here, than no diminishing returns... unless you think an 8% blend is going to damage the DPF or something

gotcha - so you think my Golf would've started having issues after 60k? in case i wasn't clear, Blue Hen, i was never running B20 - i was splash mixing into D2 at somewhere in the 5-8% range.Issue is oil fuel dilution, if anything I believe Bio is better than dino for the DPF.
Many states (especially farm states) have tax incentives for biofuel blends. One of the reasons by 10% ethanol blends are almost always cheaper than straight regular.gotcha - so you think my Golf would've started having issues after 60k? in case i wasn't clear, Blue Hen, i was never running B20 - i was splash mixing into D2 at somewhere in the 5-8% range.
our B20 pump is always 25 or 30cents below D2, fwiw.
I'd just go with what VW stated about those who live in B20 mandated states of reducing the OCI to what 5-7K instead of 10K to cover their butts.I don't know but I have been following the biodiesel threads since my first 2009 JSW. The oil dilution issue is always mentioned. Has anybody here had a real issue with said oil dilution either showing up in an oil analysis or engine wear or failure? Like I said it is always mentioned but to my knowledge, no one has ever made any reports about it in their TDI. DBW cautioned against biodiesel due to injector coking and has witnessed it.
My point exactly!But I haven't seen any reports of catastrophic dilution.
I run b20. I have done multiple uoas on my 2012 golf. Nothing but normal wear without the flashpoint dropping and no indication of fuel dilution. I have indicated the b20 use to the lab. Does not mean others have had the same experience. If you own a tdi and do all short trips inner city you may be headed for trouble. My driving is mixed but I really do not do all that many short trips. The grocery story is 2 miles away. And that only happens once a week. My 2 cents...My point exactly!

Edit: forgot to mention I do 10k mile pic. No problems thus far
Which IS the point
There is-are folks who some-lot-any short hops.
And worse -- sometimes a life style changes, or even the driver-owner changes.
BIO will not safely fill all applications
And then issue of warranties
