According to Ashland, Valvoline invented the High Mileage oil. Apparently these oils do have extra seal conditioners that work to help restore and prevent seal aging. I used to think it was all marketing, but Valvoline lead me to believe there is chemistry behind it.

If I'm not mistaken, seal compatibility is another improvement with GF-5.

I don't know what/if any seal additive Mobil is using. I have always thought that running a good synthetic oil should keep engines in good shape by keeping the engine clean. Esters also help. My brother's Toyota V6 with 220k miles on it developed a seal leak and Mobil 1 HM stopped it. He used regular Mobil 1 from 37k-190k.

I've been debating on switching over to one of these oils.

I would use M1HM. But why are you using an HM oil if your engine is not consuming any oil? If you are wanting to remove sludge then I would definitely use M1. Otherwise why not run a standard Synthetic since you change oil so often?

Thank you again for all the replies. Not to bring this back from the dead however, Valvoline has a rebate offer going at the moment and just wanted to make sure everyone knew about it. I think you just have to register your vehicle through their website and you can get the printable PDF rebate form.

Thanks again,

Yodash89

I have AGONIZED over thsi exact same thing.

IN THE BLUE CORNER: Mobil 1 -FULL SYNTHETIC- High Mileage.. Oooo. Aaaaah.

WALMART: $23 for 5 QUARTS...
POINTS FOR: Name and Reputation.
API SERVICE: SL.

IN THE RED CORNER! Valvoline MaxLife -FULL SYNTHETIC!!!-

WALMART: $22 for 5 Quarts ($15 for Blend, but Full Synthetic is alluring to me.. cant go werong, and why not.)
POINTS FOR: Name, Reptation.. AND Additive Pack of MaxLife, HIGHLY acclaimed.. AND ORIGINAL High Mileage Oil in BLEND!!
API SERVICE: -SM-

Based on this.. I choose MaxLife. Particularly if yo uhave been using MaxLife SB already.

This i have thought, over, and over, and Over...

I would be more suspicious of M1, as it seems to be more "High Performance" (Corvette, Porsche, etc) and less "High Mileage" Reputation.

2cents

Oh, and PS: They had Full Synthetic in 5W-30.. M1 HM in only 10W-30 and 10W-40. V ML FS in all three grades.

I had to make this same choice (or maybe I chose to have to make this choice...).

In the end both are super oils, with stout HTHS numbers. The FullSyn Maxlife is ACEA A3, HTHS=3.5 I read here in some post.

The M1 HM 10w30 is supposed to be stout as well, and all PAO, from what I hear. I chose the ML because I wanted to stay with 'spec' weight in my truck (5w30) and I cannot find the M1 HM in 5w30. That was probably a good thing because since my last change I've come to believe the M1 HM 10w30 is better than the same oil at 5w30.

All in all, its a can't lose situation.

M1 10w30hm has the lowest pour point of the entire M1 line at -54. Its suspected to be mostly pao, has a hths of 3.66 and on top of that has about 100ppm moly, 200ppm boron and 1000ppm phos or SL levels. Talk about kick arse. Compare that to GC which similarly has an hths of 3.7 but no moly or boron! The 10w40hm is what I use in my modified supra and the engine is so smooth I cant believe it! Its hths is 4.06, perfect for the turbo. The 10w40 pours at -39. So my vote goes M1HM by a long shot. You can always get it for less than $5 a quart too.

M1 HM 5W30 is at my wally-mart, but I wonder at what phase of the mileage do you up the oil weight (e.g. from 30 to 40). I got 170k on the odometer and my engine specs 5w30 but consumes less with a 10w40. So, I mix the 10w30 and 10w40 M1 HM and get a great result.

So you really like the M1HM by a long shot?

Beyond a shadow of a doubt, I'd recommend the Valvoline. approved

OK we will compare the 10w30's because maxlife syn doesn't come in 10w40.

Mobil 10w30hm: $4.20 quart (wallymart), -54 pour point = PAO base stock which is much more expensive to produce just like german castrol and it even smells similar, 100ppm moly, 200ppm boron(boron is the best EP agent available and is just now showing up in motor oils but its really expensive) 3.66 hths, and SL rated 1030ppm zinc 850ppm phos.

Maxlife 10w30: $7.50 quart (everywhere)havent seen it at wm, -39 pour point = GRP III dino juice, 300ppm moly, NO boron, 3.5 hths, SM rated 830ppm zinc, 760ppm phos.

If prices were equal I'd still choose mobil 1 HM anyways because of more zinc and boron additives and the PAO base. Now because maxlife costs almost twice as much is even easier to choose the mobil 1. If your going to spend $7.50 a quart it better be PAO base at least! Might as well get some redline for a couple bucks more. My vote Mobil 1 HM all day long baby.

I'd pick MaxLife. Only caveat is that, from reading VOAs on it, I wouldn't stretch it much past 5,000 miles. It has an excellent add pack, but its TBN seems to get pretty low beyond 5K.

I think that's a moot point though anyway since 5K on any dino or blend is just fine IMHO.

MaxLife is cheap here. $18 and change every day at WM for a 5L bottle. That's about $3 a quart? Valvoline oils are always better priced here than their Mobil counterparts (this is a regional thing with WM).
