Went to go change my oil today and at 115,000 miles decided to purchase the high mileage oil. Any thoughts on whether it works better for my truck?

Never put high mileage on a vehicle without changing the oil often....

If you cared properly for your truck until now then the "high mileage" oil is just a sales gimmick.

Older trucks that have carburetors no ECM systems, should respond to a heavier oil, say still a multi-weight. I have used 20-W-50 even year round on older vehicles instead of 10-W-40 when miles pile up.

With a EFI...ECM controlled vehicle then during Winter season, stay with the OEM stated recommended weight oil. A sluggish reduced starter crank-over speed during Winter can cause engine fuel flooded condition, on severe cold dipped days.

ECM/EFI systems function as mapped programming for the cold start fire-up of the engine during the engine's low RPMs at crank speed, stiffer oil density can interrupt that at times. Also not every battery is near it's youth days in vehicles, along with average starter wire/cable connections.

A good proper oil filter is important each time the oil is changed to be installed, and I always fill my filter with oil before installing it, older ignitions systems(distributor/coil types) can be dis-functioned for a oil priming moment without start-up loads until proper oil pressure is reached by initial crank-overs. (Old-school stuff) DIYed!

Only one Summer I did use high mileage oil. I had drained it from my motorcycle engine oil tank, #40 heavy duty, that was still clear and included two special additives.

The tranny took #50 wt.+ (Slick 50) added, and the primary clutch used #10 wt.no additives. I changed all the oils but only reused the engine oil by straining it when heated, later used it all season in my mowers/tiller only with good results.

I did thin the 40 wt. a bit with Resilone I think it was called then, that higher mileage oil saved me some extra money, oil was about $1.69 qt. for detergent. Also I have used strained pre-mileage oil for my chain/saw as bar oil with a bit of viscosity additive added, works fine!

Personally I don't bother with the high mileage oil. My car is at 141k miles and runs just fine using the recommended 5W20 oil. I've been changing it every 5k miles since I bought the car brand new. Doesn't burn any oil yet...

I drive a VW Jetta TDI. The oil changes come at 10,000 mile intervals. VW charges like 90 dollars for a change. They also require a European grade spec of motor oil. Its the same as BMW uses.

If the vehicle isn't using any oil of significance or leaking oil, leave it the way it was with the oil you were origionally running.

A standard oil change is so cheap and quick now that expensive synthetics and high mileage oil are not worth the extra cost.

I used synthetic blended oil not high mileage that has no redeeming value what so ever. Oil is Oil in its basic form. I think high mileage is just some marketing ploy to sell oil more expensive even though it will do the same as the regular oil of same grade otherwise that API label would have to save something totally different then what it says now.

Oil is oil, as long as it meets the specs for your engine type, you're good to go.

I have been using it on my 98 Ranger with 200,000 miles on it. It is better for the older seals. I have no way of knowing if it really is.

The OP is referring to oil for high mileage engine's, not extended drain interval oil.

Its a sales gimmick.

There are oils rated for extended drain which is not a gimmick but if your engine's manufacturer doesn't specify then its not wise to use for extended drains, just normal drain intervals.

Sadly, Mobil 1 is mostly Group III petroleum. That's why they can compete with mineral oils. True synthetics come from Group IV and V and will always be substantially more expensive.

As for whether a high mileage oil is necessary, it depends upon whether an engine is a "high mileage" engine or not. Operationally, a high mileage engine is one that leaks and/or burns oil at the rings and valve guides or leaks oil at the gaskets.

Mileage is actually a very poor indicator of engine life. Modern engines can go hundreds of thousands of miles before they need a rebuild if they are properly maintained. Thank your federal government for this because modern cars have to maintain clean emissions for up to 150K miles so the OEMs have had to build engines a lot better than they once did.

The high mileage oils contain more of leak additives to address these problems.

If you're seeing oil seeping from the gasket, most noticeably at the valve covers or you're seeing smoke and/or you're adding oil between changes, they maybe the high mileage oils will help. Otherwise you don't need a high mileage oil though as Valvoline notes, you can use a product like MaxLife anytime.

In my personal experience using a true synthetic lubricant has meant virtually no engine wear. I installed a true synthetic in my Ranger at 782 miles and I used that same oil (no changes) until March, 2011. During that time, I burned about 4-6 ounces of oil. The company making the oil requested that I return the oil to them for analysis and they replaced all the oil I sent them for free. They were surprised at the small amount of oil they I'd used so they wanted to know more. They make what's called a "Service Fill" oil that refreshes the oil's additive package in engines that don't burn very much oil. Now, every 20K miles, I have to drain 4 oz of oil to make room for the "Service Fill" oil.

I have also seen virtually no seepage from the gaskets and the engine aside from some dust, is pretty much factory clean.
