Guess what's being discussed over @ the RPM forum this am?
Rotella T 30W oil vs IH #1 30W. It's a new topic, I'm sure more good info will come. Aaron who posted the following is an Amsoil dealer but doesn't let that sway his recommendations. He takes his engine lubrication very seriously.
"You really should not add anything to the oil you are using. There are plenty of additives in it to protect the engine. If there were and engine failure due to the mixing of additives causing a fallout it would void the oil warranty. Rotella is a CJ4 spec oil and still has about 12ppm of ZDDP. It is still a robust oil. I recently posted an oil sample of CIH 30W oil and feel it is a better oil than the Rotella since they have went to CJ4 specs. Most likely the TBN (Total Base Number) which is measure of the additive package in the Rotella is around 8 to start with.
The Case IH is still an off highway CI4+ oil and had the old additive package and still over 11 TBN. This can give longer service live out of the oil. The zinc and phosphorus are up around 15 and 14 ppm also. I feel it's a better oil for the older tractors but am sure they will live a long life on whatever they use."
