If you use the same viscosity Pennzoil Ultra and Pennzoil Conventional then I doubt you will get a measurable MPG difference.

Out of the bottle I'd agree. but what about the point at the end of the OCI, that is when the differences should be noticed.
If your OCI is 3000 miles and 3months then probably not.

Ding..ding..ding!
We have the winning post.
If we assume that a synthetic oil has any advantages, then why not use it for the same or less coin?
Considering the cars in my sig, 2 have FAR syn in them, one has $12.15/jug syn, another has FAR syn blend while the spendthrift oil was TGMO at $3.64/qt.
Deals abound, so why not take advantage of them?
Of course, traveling too far down this path soon leads to a few hundred quarts of FAR or really cheap oil.
Probably not a bad thing, if you have enough vehicles to maintain.
We have two more than will fit in my sig, so I may qualify.

I've run Pennzoil conventional straight/blended with PP and have very good results from my neighbors used oil analysis. Some of my favorite blends for the hot NYC summer runs are 1 Gallon of Pennzoil conventional with 2 quarts of PP or 1 Gallon of Shell Rotella Triple protection 10w30 and 2 quarts of Formula Shell Dino in API-SM and/or Formula Shell full synthetic. The blends hold up well in the summer heat and city traffic and will last up to 7K with spotless engines.

Currently, I'm up to 6K on a sump of Formula Shell Dino, API-SM, and I'll be changing very soon to Pennzoil conventional API-SN with 2 quarts of PP.
