Hello. I wanted to get you guys opinion on something. Since Dexos Gen 3 is the standard now, before it actually came out and gen 2 was the standard, do most oils have to be reformulated or are most oils with their current formulation (pre gen 3) good enough that it meets Gen 3 specifications and they get to slap that license on it.
The reason I ask is, I was tinkering around on the boards and look at voas and manufacturer PDS’s and what I notice is before and after they are Gen 3 the sheets seem to stay the same on a few that I’ve looked at. If they were reformulated to meet Gen 3 specifications wouldn’t that also change some of the PDS info? Sorry if this is a dumb question.
For example I heavily use QSFS in my WRX and Chrysler 200, one uses 0W20 the other 5W20. Pre gen 3 the PDS’s are excatly the same. Other than now the bottles have the gen 3 logo on it and the PDS has the Gen 3 license on the sheet. Was the oil already so good that it met specs, and no reformulation was required? It’s not just QS, I’ve noticed this on other oils too like Pennzoil.
Thanks for your time, hopefully someone with a little more knowledge in this area can chime in.
