reccomendations??

92 80 has 204K on it. Just bought it going to change the fluids. best weight and best oil to use... i think it's a little to high for synthetic but I don't know. Best tranny fluid??? best T-case fluid? best Gear fluid??

Going to do the tune up... o2 sensors were done 3 months before I bought it but is there a good set of performance wires. and what about plugs.... I was thinking those new diamond fire ones or some bosch + 4

OEM plugs. OEM wires. OEM...etc...


oil? dunno...you could try synth, but I don't know if it's worth it at your stage...but I don't think it'll cause any problems. If going full synth, I like Mobil 1.

I like Delo...

I have had good luck with Chevron Delo 400 in the 15w-40. It stays in my leaky seals the best. I've been around several million miles of diesel truck and equipment usage, and the wear analysis from this oil is outstanding with our fleet.
