Would there be any benefits to running a High Mileage oil early in a vehicles life?
High mileage oil early on

Can't think of any.
Not really. In my experience, High Mileage oils tend to be a little thicker in the grade as non-High Mileage oils, which tends to make them feel a little more "sluggish". This at least is what I noticed in my Cavalier, and the Mustang. The cavalier would have bad lifter tick with thicker oils, and the Maxlife 5w30 made a racket compared to QS UD 5w30, and Havoline DS 5W-20.

This has been discussed before. The general consensus is there is no benefits to using a High Mileage oil early on.
I'm running Max Life in my Frontier with only 13,000 miles on it. I just wanted a thicker 5w30 to try in it. So far, I'm not seen anything different than a regular 5w30. Gas mileage is even the same.

Yes, it will maintain your seals by keeping them pliable. Once seals start to harden up, they no longer seal.

I'll pass on the seal sweller. No High Mileage oils for me.

I wouldn't use a high mileage oil until I had a reason to do so.
Mobil 1 High Mileage oils have a really good add pack and I use them in cars with 8K miles and 53K miles. Both vehicles run very smooth on this oil... Possibly Mobils best oil.

Which High Mileage oils contain "seal swellers"? Not seal conditioners, but swellers? I can tell you that MaxLife does not "swell" seals. Why do people believe this?

I have never used high mileage oil and I put 200-300K miles on my cars.
(Mobil 1 5w and 10w30) Love the extra high ZDDP. This is oil that is driven by capitalism and not govt standards. Speaks volumes for me.

Why do you love it? What exactly does it do for you? What's wrong with normal amounts of ZDDP? Just curious...

Well, first let's define the function of ZDDP: antiwear, anti-corrosion, anti-oxidation.
Therefore, my logic is the higher levels provide better protection.

I believe Merkava is correct on this point. Valvoline Maxlife is one that contains seal conditioners not seal swellers according to Valvoline tech support. Here is a clip from the "What is in my Oil" article posted on this site under Articles of the Month.
"Seal Conditioners: Also often esters, seal conditioners are potent additives used in small dosages and designed to keep seals pliable. These are especially important for highly paraffinic base oils such as Group IIIs or PAOs due to the tendency of these base oils to shrink and harden seals."

Because it is semantics by the oil manufacturers.

Well according to this quote, seal swell isn't restricted to High Mileage oils?
