Wow, That's a great price.
I got 2 filters off amazon, ready to go. Awesome
Your 2 selections are more $$, but Walmart is still the place to go for them also. The reason behind M1 High Mileage was experience. I would almost guarantee you get a external gasket leak switching over to Full Synthetic at that mileage. Normal. gaskets and seals don't last forever, outgass over time. Natural aging. Shrink and harden from repeated heat over that many years, that many miles. Full synthetic oils find and expose shrunken seals slipping by them. Leak. or..maybe all the rubber on that engine has already been replaced and your good to go.
LeakySeals,
What about a vehicle with 115,000 miles do you believe that the seals on an engine with this mileage will leak switching to Full Synthetic? I just purchased the vehicle and would like to switch to Pennzoil Ultra. I don't know what the history of the vehicle is before I purchased it.
If its never been apart, I would think something will leak from somewhere after a couple oil changes. Anywhere from being wet to a drip. Go ahead and try the PU. If it leaks just switch to a High Mileage Full Synthetic or fix it.
Important: As stated above the Full Synthetic doesn't cause the leak, it exposes a pending leak that was not breached by thicker flowing conventional oil, or was clogged by deposits that a Full Synthetic will remove. Once the leak is exposed, once oil gets in that breach, its almost impossible to stop without repair. A High Mileage oil can swell it, stop a drip, but it will always be "wet" once its breached.
