T4 is conventional oil, T5 is semi synthetic, and T6 is full synthetic. I switched at 400 hours to the Rotella T5 15/40 and change it every 100 hours and the black stone labs oil test shows all is good!!!

FYI for those running T4: Shell has stated that Rotella T4 is not safe for catalytic converters. It’s a shame, I ran T4 in my 1993 Nautique for years and sold it with 958hours and it never missed a beat. I’m hesitant to run it in my Assult 340hp engine based on Shells warning. Thoughts?
Currently, I’m running Lucas marine 25W40 and just let it warm up a lot before pushing it based on the 25weight. I didn’t have very good luck finding 15w40 that met the Indmar requirements.
“Shell Rotella T is a line of heavy duty engine lubrication products produced by Royal Dutch Shell. The line includes engine oils, gear oils and coolants. The oil carries both the American Petroleum Institute (API) diesel "C" rating as well as the API gasoline engine "S" rating. Ratings differ based on the oil. Rotella oils like T3 15w-40 meets both the API CJ-4 and SM specifications, and may be used in both gasoline and diesel engines. However, it is formulated specifically for vehicles without catalytic converters, containing phosphorus levels beyond the 600-800ppm range.[1] Therefore, Rotella is not recommended for gasoline vehicles with catalytic converters due to the higher risk of damaging these emission controls.[2] Newer formulations of Rotella T6 however are API SM rated as safe for pre-2011 gasoline vehicles.”Last edited by Glenwyatt; 06-09-2019 at 09:56 AM.

SN is what the raptors require.
But great points on having too much ZDDP will harm cats. It’s not really clogging but it makes the catalyst less effective.
All engines consume oil especially under loads, even worse on boosted engines.
The 400/450/460’s don’t need crazy amounts of ZDDP. The cam ramps are not that aggressive.

Ok. Am I assuming that it is just the 340 that it affects and not the 325 FI engine? Or is there a catalytic converters on the 325 engines?

as far as I know there are no Cats on the 325hp engine of the same generation as my 2008 XLV. The 2008 340hp does have cats.
