Ecodiesel Oil Analysis - updated 11/23/23

Candidly, I don't think he knows what he's talking about. His base assumption is that the lower TBN and detergent numbers are signs that FR3 is made of chlorinated paraffins, but he provides no evidence either for the claim that chlorinated paraffins lower TBN and other detergents or the claim that FR3 has chlorinated paraffins. On a related note, he attributes the lower TBN to the FR3, when in reality the lower TBN is due to the fact that the base oil the poster used was a mid-SAPS oil, not a full-SAPS oil. But don't take my word for it, you can just look at AMSOIL's bulletin materials, which will tell you that the mid-SAPS 5W-40 is formulated at a lower TBN (and again, keep in mind that the poster stated he was using the mid-SAPS for the first time when he decided to give FR3 a try):

In short, the statement you quoted from OhioTech shares the same flawed assumption: he attributes lower TBN and overall detergents to the addition of FR3, not the fact that poster was using mid-SAPS for the first time instead of full-SAPS. And based on that flawed assumption, he out of nowhere just claims that FR3 must be formulated with chlorinated paraffins.

TLDR, I wouldn't put any stock into his opinion on this.

Thank you for the explanation, hopefully this helps a few people here. I'm thinking full saps and pray for dpf

I don't blame you. Stays within warranty, and the AMSOIL Full-SAPS and Pennzoil Platinum Euro have proven to be solid oils. One thing you can do to protect your DPF's longevity other than oil choice is use fuel additives that have injector cleaners and cetane boosters. The cleaner and more complete the burn, the less soot the engine will produce, thus, less loading on the DPF, fewer regens, and overall less wear over time. Personally, I use Hot Shot's Secret EDT every fill up and their Diesel Extreme every 6k miles.
