That's like saying a pound of lead is heavier than a pound of feathers.
If the new oil meets exactly the same specs, and if the specs define what you need, then by definition you are getting the same performance.

And just how do you intend to discern how the "cheapening" of the oil is affecting you? Are you performing long-term double-blind trials with each kind of oil with large groups of equipment?
I'll tell you who is doing just that: API, ILSAC, ACEA, the OEMs, and the formulators themselves. Evidently, they all think group III is great.

Then you want to blend your own oil, period. No responsible corporation will spend more and charge less than they have to.
And FYI, if you think $20 for 5 qts is expensive, you have some research to do. There are oils that cost four times that much for the same quantity.

Yes, actually, one does. If you don't, then you're just taking someone's word for it.
And once again, the people who DO have the degrees and ARE doing the experiments all seem to think group III is just fine.
Are you serious ?
You use a pound of feathers and a pound of lead analogy as if a given weight of an item means the item is of the the same . OMG ?
I am not here to word smith anyone on the internet .
And replies such as yours prove that companies such as Castrol will be around a long time.
I am done here
