With the confusion that surrounds labeling. I wonder if anyone has attempted to do the legwork or even if it's possible to publish a list of synthetic oils and what their major base oil components and their percentages. As a consumer I want to know if I am spending money on class III base versus IV or V and the percentage of each. I'm not speaking to the relative quality or performance of any specific oil. I just wonder if say the Walmart brand 10w30 synthetic does or doesn't have the same basic makeup of a name brand at half the cost. One of my vehicles requires a Mopar spec 6395 and I can get oil for that specification in the synthetic branded types from about $4 to $12 a quart. Most of the synthetics are bunched around the $6/qt range. For example: Is the $7/qt Castrol syntec with 95% class III a better deal than the Walmart labeled brand with 95% class III for $4/qt? On any given day the Walmart may be produced by any number of different manufacturers so the specific assay may change a bit.With that being said it would be difficult to do an apples to apples comparison but you should still be able to ascertain who is profiting the most fro ambiguous labeling.
I'm not saying that one oil is better than the other. I'm wondering if I'm being gouged and by how much and from who?
