Best high-mileage oil for my application??

[MrWideTires]

So my 2001 Suzuki XL-7 (2.7 V6) is leaking a bit of oil.
It's only a couple drops overnight but it's something.. This car used dino until around 60k miles, then I switched it to supertech synthetic and now to Rotella 5W40 and it's at around 86k miles.
I don't like how thick the Rotella is and it makes it feel sluggish.. and it turns out it's leaking a little.

So I want to try a mix.. maybe 65% high-mileage 5w30 oil to see if it cures the leak, and 35% synthetic like Mobil 1 0w40.

What is the best high-mileage oil though? I've never cared or read anything about them until now...

Try Mobil 1 High Mileage 10w30.

Valvoline Maxlife synthetic, or the Mobil High Mileage

I have been adding 1/2 quart of high mileage oil at my regular OCI to stop a small leak for years. Any brand seems to work ok, but I usually use Valvoline or the cheapest I can find since I'm doing 3k OCI's. YMMV.

Rotella is available as 10w30 and 0w30 as well.
