High Mileage Formulas

High Mileage Formulas
My owners manual seems pretty adamant about using a motor oil designated as "Energy Conserving". And this makes sense. But I have yet to come across a "For High Mileage Engines" oil rated as being energy conserving. I have two questions:
First, Are so-called "high-mileage" formulas so much different and will it make a difference in my car? (which has 235,000 miles. High indeed)
And Second, if forced to choose between a high mileage formula and a motor oil rated as being energy conserving, which should I opt for? So far I've gone by the book and use an Energy Conserving oil. I don't typically trust marketeers over engineers.

Energy conserving motor oils tend to be lighter weight than other motor oils. High-mileage motor oils tend to be heavier weight than other motor oils.
I would say that if you have successfully been uisng energy conserving motor oils and do not experience too much oil consumption, I would stick with them. I would say that if you burn much more than a quart of motor oil between oil changes, you might want to consider using a high mileage motor oil to reduce the oil consumption. You loss in gasoline mileage will probably be difficult to measure.

Valvoline 10w30. Currently i experience little to no oil consumption between 3000 miles changes. Any loss is negligible anyway.
But with 236000 miles i would deffinately consider myself high-mileage and was just wondering what made "high-mileage" oils "better" for engines such as mine. Maybe they just mean american engines with over 75,000... that tend to be where they start going. I wouldn't be surprised if i could get atleast half a million out of mine, if the rest of the car cooperates

I would stick to what you are doing. If you are not burning any oil between changes, you certainly don't need high-mileage motor oil.
Given the mileage on your engine, I would resist the temptation to go to synthetic motor oil.
