Is TRUE Full Synthetic Oil Over Kill On Older IDI Diesels? - PeachParts Mercedes-Benz Forum

After doing hours of reading on BobIsTheOilGuy, I've realized all but a handful of "full synthetic" oils are actually dino based. Including Mobil 1 and Rotella T6(what I currently use).
I'm only interested in group v and up.

Being that soot is the limiting factor for our older engines, is there really a point of using something like Amsoil Signature series oil?

The soot levels would cut it off short long before we can get the most out if correct, even for the newer 60x engines right?

Curious because I was considering buying this stuff.

Read up on bypass soot filters to extend drain interval.

I have heard that this is the best place for ANYTHING and EVERYTHING motor oil. My friend Chris spends a lot of time there as well, and he is a wealth of knowledge that I tap into if I have any oil related questions.

Will do.

Edit: I see now, that's pretty much the only way to get the most out of the oil, this is exciting honestly. I'll definitely do this once I get a few repairs out of the way. Looks like you'll save money in the long run, especially if it's a daily driver.
