I know it's been a while since you asked, and hope you've been able to get your hands on
renewable diesel. For those wondering, renewable diesel and biodiesel are both made from biomass, but they ARE NOT the same.
RENEWABLE DIESEL (R99 or R100) is chemically the same as fossil diesel, so it is 100% compatible with ANY diesel engine...cars, trucks, heavy-duty freight, boats, diesel trains. But it's made from 100% renewable raw resources. For example, Neste MY Renewable Diesel is approved by wide range of OEMs and it is TOP TIER certified. You can mix it with fossil diesel in your tank or go 100% pure, which cuts GHG emissions by up to 75%.
BIODIESEL (B100) only works with engines designed (or modified) to run it. For anyone else whose OEM has approved biodiesel, it's usually at a much lower blend ratio like B5 or B20, meaning you're not getting the full GHG reduction. It's also less performant in cold weather.
On top of that, there is evidence that renewable diesel is better for the engine than even fossil diesel, since it burns cleaner. That means fuel injectors and filters can go longer without the same level of corrosion or soot build up that you may experience today.
If you've been curious about renewable diesel, it's definitely worth checking out.
