When ask if it met spec the answer was simple. Yes it meets minimum API spec which meets your automobile license but if you want your vehicle spec you can use our premium product. Looking at specs premium product is latest formulas and store brands have older formulas that still meet specs. Nothing wrong with it just not the latest formulas that don't have the backing of major oil companies (ie Valvoline won't back Napa). If you ever have a problem with the oil you must rely on store you bought it from. These are facts.
Supertech shares the same DEXOS1G2 approval as MAG1 (a highly regarded oil). They are nominally similar, if not the same.
Re-brand companies like warren are LOATHE to say that everything they make is similar/same. You'll get everything but a straight answer. Look at the approvals.
I would say they are the same product. It wouldn't make financial sense for them to make a slightly different one. These are house-brand geared products blended and tested to meet the minimums for their respective approvals as cost effectively as possible so that they can still make a healthy profit.
I once looked up the warren supertech by upc code. It pulled up a wpp msds. Back before supertech was even advertised as meeting dexos it was listed on that same msds. Pretty much all supertech is wpp now days. I also think it's just about the same thing as mag1 of not exactly.
