Just stopped at a 76 station with the renewable diesel. They only had renewable diesel and not the standard petroleum variety. Very interesting. And nice to have another source of renewable diesel.

I don’t how the price compares to other 76 stations. I have pretty much only used Propel HPR since it has been available. From what I have seen, the price seemed about the same as regular diesel and Propel HPR. This 76 station is at the corner of Fair Oaks Blvd and Watt Ave.How does the price compare to other 76 stations that just have D2? Also, where in the Sacto area was the station you visited?
You guys are lucky. Go even further north and it gets even harder to find. Washington state in particular is slowly loosing touch with sources.
I was told that Propel isn't sourcing their renewable diesel from Neste any longer, instead relying on smaller independent refineries in North America.
I'm excited to know there is another option at 76 stations, however the 2 locations in Sacramento are not convenient for me so I will continue to use Propel.
You made me wonder the same thing. I found this on the interwebsI wonder what determines the number, the type biomass used, ratio of animal to vegi biomass, or just amount of refining?
Ive seen Neste RD leak so if REG RD doesn't leak that alone is a huge difference to me lol. 76 RD claims 70+centane so if REG RD is 60 that means 76 might be getting it somewhere else, or adding an additive package

Hexadecane (cetane)
is the reference compound used to assess the ignition
quality of a diesel fuel on the cetane scale, a concept
similar to the octane number used for gasoline. The
carbon chain length of the alkanes present in diesel fuel
determines the cetane number.
Diesel fuels containing large amounts of shorter-
chain and isomerized species have lower cetane num-
bers while diesel fuels consisting mainly of long-chain
alkanes have higher cetane number. ASTM D975 and EN
590 are the commonly used petroleum diesel standards
in the United Stated and Europe, respectively.
In general, vegetable oils consist primarily of triac-
ylglyceride molecules. Low concentrations (<2 percent)
of free fatty acid (FFA) molecules are also present in
vegetable oils. Both triacylglycerides and FFAs contain
relatively long, linear aliphatic hydrocarbon chains,
which are partially unsaturated and have a carbon chain
length and molecular weight similar to the molecules
found in petroleum diesel.
Hence, the cetane number of diesel fuels derived
from renewable resources such as vegetable oils is high,
over 70. Long-chain alkanes are less desirable because
of their adverse effects on low temperature properties
of diesel fuels. Shorter-chain compounds improve cold
flow properties of diesel fuels.
Leak as in it leaks in your car when you use it. It seems like there is a good handful of people who have had this experience. Ive seen it happen first hand on alh engines. Im sure its safe for newer vehicles tho. And im sure it has more to do with the vehicle itself than the fuel, but after seeing what i saw id rather be safe and just avoid the stuff. Im definitely down to give it a try now if they have a new supplier tho. I recently learned that these companies dont make their own RD they just buy it and resell itOops I may have reversed the cetane numbers. if so,
What do you mean by "leak"? I've carried Propel's Neste-sourced DieselHPR in a fuel container and never saw a leak.
A few paragraphs later it says animal fats reduce the viscosity to closer to that of petroleum diesel so yes it seems your statement may be accurateThanks, Louie.
So a lower cetane numbered RD may have a higher animal biomass to vegetable biomass ratio, if I understand the citation.

How would it get into the oil? Is the stuff not burning?Well the 76 RD ended up leaking from my injection pump. I think it got into my oil as well. Filled back up with regular diesel and the leak is gone. Has my car ever been filled with biodiesel? I have no clue. Its a 02 wagon i bought with a salvaged title 210k miles automatic transmission and no type of info on past maintenance. Its at 233k now
Leak at the injectors. My oil level went up and its definitely not coolant thats getting in there or id have a whole bunch of chocolate milk to put in the fridge lol and ive never heard of oil levels just magically rising without adding more oilHow would it get into the oil? Is the stuff not burning?
Have you ever replaced the seals? If not I'm surprised it doesn't leak with D2. My '2 leaked with D2. Never used anything else.
I don’t know if this has anything to do with it but HPR and renewable diesel have even less sulfur than ULSD.
Yeah i knew the risk before i did it. Fortunately the leaking stopped with regular #2. I will be keeping an eye on it in the future tho now that the system has been compromisedAnyway, the leaks when switching to HPR or renewable diesel might be considered a warning that your pump seals are aged. The pump will probably eventually start leaking no matter what fuel you run.
The OP was a troll.This thread got weird fast.....OP got lost after the 1st page?
