johnnnymaccc,
Basically the High Mileage motor oils have more seal swelling additives in them than the standard oil. The ideas is to cause the seals to swell a little more to stop or prevent minor leaks in an older engine.
Hope this helps

i work for valvoline and we offer 2 high mileage oils, maxlife and maxlife synthetic, in my opinion they are both good oils, there is no HM oil out there that is a miracle worker but for slowing down and stopping small seal leaks they will definatly do some good. i can tell you this much they won't stop a cadillac northstar engine from burning oil....but then i dont think anything will.\
and as far as the viscosity of the oil right now the maxlife is avalible in 5w30 10w30 10w40 and 20w50 and the max life synthetic in 5 and 10w30

If you are following a good OC interval, changing the oil filter everytime, and your engine is tight, then I see no use for spefically changing to a high mileage oil.
When you think of it, high mileage oils are less than a decade old. So before then, there was plenty of "high mileage" engines, running on regular oil.
If you have an engine with "issues", then a high mileage oil might provide some usefull benefits. However, if not, I would continue using what oil and correct viscosity you were running, and you'll be fine.

I bought some tonight, Castrol GTX High Mileage, put it in my Aero with 240 thousand K. See if it makes a difference in how much I lose between oil changes, though I am not losing much now as it is. Price was right, it was on sale for $13 bucks and I had a $3 dollar coupon as well for 4 litres

I am sure the dated "straight weight" oils have a small, nice market that is getting smaller. Who uses SAE 30HD, 40HD, 50HD anymore? Loose or worn beater engines, where the thick, honey-like oil helps to smooth gaps in cylinders, ect.
I have even switched to a multi-viscosity oil in my lawnmower, edger, ect. 5w30 or 10w30 oils in the trusty Briggs & Stratton or Honda small engines. Both oils work fine in these small workhorse engines. I will never go back to straight weight oils.

I guess there is little need for straight 30. Most mowers and generators nowadays recommend a multigrade anyway. I guess it is partly because the quality of VII has gone up so much recently. Anyway, Maxlife 10w30 performs so exceptionally well that there is no need for a straight 30. In fact, a 10w30 will be thicker above 100C than a comparable straight 30.
Well, now I guess I should save one of my few remaining straight 30 Maxlife bottles unopened for the future. Someday it may become a collectible, aye?

TP, Perhaps it's a good time to post a link, showing your legendary home oil stock? Even if you have less than you had in the past, I am sure it is still 95% better than any other personal inventory!
Any new members of the FTE, will appreciate such a well thought out personal oil supply.

PS There will always be some use for your straight weight oil inventory. I did not mean to imply a staright weight oil is useless. Only that, if someone has the chance to purchase a multi-viscosity or straight oil in the future, today's modern multi-viscosity oils hold up quite well in comparison.

I could list it out from memory. Total is about 130 quarts oil plus additives.
Lets see:
Maxlife Synth 10w30: 20 qts
Maxlife 10w30: 30 qts
Maxlife SAE 30: 5 quarts
Maxlife 10w40: 18 quarts
Durablend 10w40: 17 quarts
Castrol Startup 10w40: 13 quarts
Pennzoil SL 10w30 synthetic: 13 quarts
Citgo Ultralife 10w30: 1 quart
Okay, somewhere I am off, but its close. Now for the additives:
PCMO additive (21000 ppm zinc): 1 quart
CD2 Street Legal High Performance Oil Boost (4800 ppm zinc): 30 pints
CD2 75000 Mile Plus additive (4000 ppm zinc): 6 pints
Valvoline Synpower Oil Treatment (1700 ppm zinc 2300 moly): one pint
This does not count ATF, collectible oil cans, or grease.
Hey, SAE 30 can be used mixed with 10w30 to make a 15w30 which is just the multigrade for a warm climate.
Lets see:
Maxlife Synth 10w30: 20 qts
Maxlife 10w30: 30 qts
