What did your truck run at the track?

 

Either CAT ELC or Shell Rotella ELC both are Red and should be purchased undiluted. I.e. Do NOT use 50/50 premix

If you have an XL Parts near you they carry Shell Rotella ELC on the shelf, no need to order it.

 

IPR High Flow Coolant Filter Ford 6.0

I have a sinister diesel filter...but I hear great things about the above. Downside is its twice as expensive as the other filter kits out there.

And yes, these things are needed for a 155K mile engine. Flying blind with no gauges and running stock things can result in major $$$ when something fails. At the very least a EGR delete is needed, that way even if your oil cooler is plugged you dont run the risk of rupturing the EGR cooler from the steam.

 

Cooler vs delete ?

 

EGR cooler vs Delete? If you live in a state with no inspections a EGR delete is the way to go for sure.

 

No inspection in L.A.

L.A. of course meaning Lower Alabama

 

Your golden. You can buy an upgraded EGR cooler, but I would just do an EGR delete and forget about it. Most lifted heads/head gaskets are probably due to this problem.

 

Looks like I might have looked at something weird before, the oil cooler doesnt seem prohibitively expensive.

I see there is a sinister "basic" kit that has most of what I would want.

 

You probably saw a oil cooler relocation kit (what IPR sells) or the BPD (bullet proof diesel) cooler kit. Once you do a EGR delete the need to do oil coolers will go down because you dont risk blowing the EGR cooler, but these are really nice (and really expensive!!!) upgrades.
