Ambra MasterGold 15w40, 90hrs, 97 New Holland Trac

[TXHunter]

Oil and filter were changed at the time of sample. Engine hit 90hrs in two years, double the previous sample duration. Going to try and get them to push the oil further next time, looks like it was a waste to change it. At this point I believe they are going to sell this one long before it needs another oil change.

That is NH's branded oil, right?

Nothing wrong whatsoever, other than the point you make about a waste of lube. Talk about a lack of wear! Those wear rates are crazy low, to almost non-existent.

Not sure how this tractor is used; you don't mention it. Seems that it gets a good warm up and decent use; no moisture to speak of. Low contamination.

Presuming the usage stays similar, I'd say doubling the OCI is easily doable; 200 hours is not out of the question here. As a grossly rough estimate, each 100 hours is potentially similar to 6k miles; assuming the "on road" equivilant of 60mph ... So this was akin to 5400 miles of use. Easily understandable why it could be doubled to 180-200 hours (10-12k miles). At 4 years, the filter might be "iffy", and so perhaps the next action would be to run it 100 hours, pull the filter off and cut it open, then install a new one and continue the OCI (no oil change). Then if that filter looks good, you'll have some idea of how long a full O/FCI could run.


As always, thanks for the info.

This is a CJ-4 oil?

Why are PHOSPHORUS and ZINC so high? Looks like a good oil for my old S/B Chevy Hot Rod.

According to Petronas, it's a CI-4 product.

Tractor use is mixed, it's the smaller of their two units. This one is mostly used for shredding, as a back hoe, and to disc/plow smaller areas. They also have a bucket in the front for moving piles of debris/dirt, etc.

I think the Zinc & Phosph are so high because it's a 97 model. No worry about clogging up emissions related exhaust equipment.

Don't know the exact specs, can look next time I'm down there on the bottle. CI-4 sounds about right.
