Pennzoil Synthetic Blend ?

[CrewChief]

Does anyone know if Pennzoil makes a synthetic blend ? I know they have the 100% synthetic platinum. Usually I cahnge my own oil but a few weeks ago I was headed out of town for the weekend and needed it changed and didn't have time. So I had gotten a coupon in the mail for a $9.99 oil and filter change at Monroe. They offered a synthetic blend from Valvoline for $19.99 with the coupon so I gave it a try, it actually seems to have helped my milage slightly. Now in my effort to support the IRL and Panther I usually buy Pennzoil (assuming they are back in some capacity) and I wouldn't mind putting this in my wife's Jeep. I hate to go to the 100% synthetic because they say once you do you shouldn't switch back where as with the blend they said it didn't matter.

as you may know, Pennzoil and Quaker State are now brand names of Shell Oil.

BTW there is NO reason that all types of oil (syn, semi, and petro) cannot be used interchangeably.
