Elaborate a little more. Dunno what R92 diesel is, but it sounds like you're talking about a specific type of fuel... "65 Year old"???

Never heard of it here. Claims to be more environmently responsible, so it must be more expensive. 🙄

Do you mean R99?
If so:
Yeah we run it and it's excellent.

AKA "drop in" renewable fuel.
Reliable sources say can be run in any diesel engine.

Pretty sure that’s what Costco diesel is at least in California. I heard a lot of fuel filter complaints from different places and on here so I typically stick to Sam’s Club. I will use it if there’s nothing else reasonably priced around me. I change my filter annually and only put around 10k miles on it so probably not going to plug up the filter either way.

I have a 2006 Duramax and have been running ARCO's R99 Renewable, since it came out without issue, I don't see an improvement or decline in mileage or performance, I change fuel filters at 10k, and run a fuel additive for lubricity from the ULSD.


IDK if it helps or not, but I know Sulfur was 500 PPM and they lowered it to 15 PPM, and they use sulfur as a lubricant.

R99 is not a diesel produced from waste oil, or any of those weird things that people put in Diesels.
It is pretty much the same as a Fossil fuel Diesel, only difference is it starts off as a Soy bean, and then is then process similarly in select Refineries.
