After a long stretch of not driving the Benz, I filled up again recently with HPR for 2.799. Great fuel, even if it is a little pricy.

Compared to #2 diesel, HPR has been equal or slightly cheaper. For a drop in renewable fuel you really can't beat it.

I've been running it for 2 years now in both the 87 and 97. Love the stuff, I wish they would open more locations.

I'm using HPR for now, just filled up yesterday, I bought one each of the two products in the photo for lubricity improvement. The Howe's product is available in the half gallon size at Amazon for $20 with Prime shipping. Comes out to about $.06-$.07 a gallon as an additive.

Biofuel Oasis in Berkeley currently sells a 20% biodiesel/80% Renewable Diesel for $3.79 a gallon. On the website they refer to the 'Renewable Diesel' as "currently made by Neste in Singapore from recycled vegetable oil and tallow." So I'm guessing that's the same product that Propel sells.

A friend in Berkeley tells me that Biofuel Oasis still sells 100% biodiesel in 5 gallon jugs. One wonders if you need to add 20% for proper lubricity. I'm guessing less would do but I don't know. And if you do so I guess you would need to upgrade fuel lines which I haven't done.

I think HPR is a nice development, my only misgiving is that there really isn't that much waste oil and fat in the world, certainly not compared to the demand for diesel. What worries me is that eventually palm oil plantations would be used to make the stuff and that is, of course, a net environmental loss.

I've been using Peak diesel boost with HPR, and I love the stuff. Acceleration feels smoother with the Peak additive.

I think that it was mentioned earlier in this thread or somewhere else that Biodiesel and HPR don't blend well.

Wow that's really surprising considering Neste explicitly warns against mixing renewable diesel with more than 7% biodiesel.

Really?! Mayhaps I should call Biofuel O and ask them about it. I used to shop there in the late oh-ohs with my 300SD.

So do you know anything about the lubricity additives I bought? I know CRC has a long and good (AFAIK) reputation, and the other product, Howe's, gets good reviews.

A maximum 7% of high quality FAME - Fatty Acid Methyl Esters aka biodiesel (total monoglycerides max 0.3 wt-%) can be mixed with Neste
Renewable Diesel as defined by EN 15940. Precipitation risk of FAME’s impurities increases if more
or low quality FAME is used. CONCAWE has given a recommendation for EN 590 diesel SMG
(saturated monoglyceride) content [Engelen et al, 2009] as well as Annex C in the FAME standard
EN 14214. These recommendations can be used also when blending FAME with Neste Renewable
Diesel. Swedish class 1 and renewable diesel behave similarly when blending with FAME, so the
same SMG levels in the final blend can be required also for renewable diesel. The max level of SMG
coming from FAME can be 20 mg/l in final blend.
Aromatic content of diesel fuel has an effect on the precipitation risk of FAME’s impurities. The
better the diesel fuel is (lower aromatics), the higher is the risk for precipitation; thus quality of
FAME becomes even more important for avoiding problems in fuel filters.
It is not recommended to store more than 7% blend of FAME in renewable diesel. There is a risk for
precipitation of impurities if FAME is mixed with low aromatic or aromatic-free fuel. Precipitation may
take place even at temperatures higher than cloud point of the blend. Due to limited tank capacity,
the same tank might be used for FAME and renewable diesel. If the same tank is used either for
FAME or renewable diesel, the normal procedure with quality change should be performed. For
example, the level of FAME should be as low as possible in the storage tank before changing to
renewable diesel. Blending temperatures should be well above the cloud points of both fuels. Then
when changing back to FAME, the renewable diesel level in the storage tank should be as low level
as possible. There is also a remarkable difference in densities between FAME and Neste Renewable
Diesel which need to be taken into account when blending.
Neste Renewable Diesel Handbook pdf - page 24

I'm kind of shocked BioFuel Oasis is selling this blend. I wouldn't use it in my car.

What is Our Petroluem-Free Fuel?
Our Berkeley pumps continue to be petroleum-free with this blend:
20% Local, Recycled, Biodiesel – Made by Simple Fuels in Chilcoot, CA from recycled vegetable oil
80% Renewable Diesel – Currently made by Neste in Singapore from recycled vegetable oil and tallow. In the next couple months we will likely be able to get renewable diesel made in the USA, and then eventually in California.
The renewable diesel is significantly better than petroleum diesel & is made from the same recycled vegetable oil sources as biodiesel. We are happy that we have the option of continuing to avoid petroleum.

Anybody heard any info on what potential share of worldwide diesel use HPR could eventually become? Not to be a cynic, and I am using it, but I have to wonder if it's always going to be a drop in the bucket.

I would guess that it will always be a rounding error. Renewable fuels are great, but they are largely subsidy dependent at this point. It's good to use waste oils for something useful, but using prime farmland and depleting ancient aquifers for fuels is just plain stupid (cough, ethanol)

Algae based biodiesel probably holds the most promise -- it can be produced in brackish ponds on crappy land.

Absolutely agree that beating up farmland and depleting aquifers for ethanol is whack, and the horror stories about palm oil plantations for biodiesel are not good. Waste oils and tallow are never going to be large amount of total energy usage best I can figure. I don't know but I'm guessing that tallow in this case might refer to rendered waste products from meat production that can't be profitably used any other way.

There have been some ads up recently by Exxon showcasing their algae research projects. Who knows, maybe something will come of it. One hopes that Exxon is not merely greenwashing.

Algae based biofuels are the only ones that have a chance at being produced in vast quantities to replace out current demand for fossil fuel diesel. Unfortunately electricity is cheaper, much cheaper. The only really expensive part is the mobile storage aka the batteries and even those are also getting cheaper.

If you took the fossil fuel fired electricity out of the mix, I bet the prices would converge...

I doubt that very much. The only fossil fuel still price competitive with solar/wind is natural gas and its advantages is slowly eroding away.

After another 6 months in the garage, the Mercedes is getting a little love with a trip out to the central coast. I'm 200 miles into a fresh tank of HPR and my gauge still reads 5/8 of a tank. I forgot how long this car seems to go on one tank of fuel.

I still have the nailing or clacking until about 15 minutes of driving have happened as well as the hot idle "rock and roll" (delivery valves for both, hopefully!) but otherwise, the engine is so smooth on this fuel.
