That hurt to read... There was no scientific data in the article to back up anything that was written. The writer simply added more fluff to Pennzoil's widely available marketing material to create a pointless article.

Being both synthetic oils and having the same primary oil base, they aren't as different as one would expect. They only differ in the number
Also, drive cycle matters. Lots of towing, short trips, idling, stop and go, cold temps, or low octane fuel will reduce the usable life of the oil.

I’ll admit my opinion came across a bit harsh.
Just submitted my information for the rebate. Thanks for this information.$25 rebate on 10 quarts of full synthetic. Must buy all 10 in 1 order. It doesn't specify what type of giftcard the rebate will come in the form of, but in the past it has been a Shell giftcard. List of eligible retailers on the rebate page. Amazon and Walmart are both on there.
