Currently all of my vehicles have over 75,000 miles with 132,000 miles being the most. Currently I've been using 5W-30 Valvoline conventional in all of them. Is there any benefit going to a high mileage oil if the engine is in good shape? Thanks.

It is not needed but will not hurt anything and will probably help in the long run. If I were you I would use the MaxLife 5w30 syn blend.

Probably not except for small, unnoticeable things. You'll see the noticeable benefits if your engine was in a state that really needed these things

IMO, case by case thing. Generally, no, but if a slight leak is forming, a slightly more robust oil is wanted, etc., it may be a good choice.

I have never used high mileage oil on any car...Not even on a 88 Town Car that had 300K miles or 99 Grand Marquis that had almost 200K miles.

you know, i'm wondering if when GF5 SN rated conventional oil comes out, I think there will be EVEN less of a need for HM oil because they will have a better seal compatability rating. it's part of the new GF5 standard...you can read about it on their website.

Thanks for the replies. I guess I will just stick with a regular conventional oil. Now I just need to decide if I'm staying with Valvoline or go with something else. I'm a big Havoline/Chevron fan but you can't find Chevron around here at all and since Walmart quit carrying Havoline, you can't find it very easily and when you do, its about $4.00 a quart.

It used one third of a quart in 9117 miles, and still looked very good. My Pathfinder had about 34,500 miles on it when I put the oil in. I was impressed by the specifications on the Mobil website mentioned above. I especially liked that it is still an SL oil, like German Castrol, and has extra antiwear and cleaning additives. A minor downside is the fact that it is too robust to qualify as a fuel saving oil.

I now have the M1 0W30 maximum fuel saving oil in it, and do not notice any change in the fuel consumption. I notice no change at all in the sound of the engine, either. Bought the 0W30 with that coupon last month.

I like MaxLife because it's 30% synthetic. I am not sure if the others have any synthetic at all.

There's no major benefit to using HM oil in an engine that has been previously well maintained in most cases. However, the beefier add pack may do some light cleaning if there are any deposits, a HM engine may or may not benefit from a slightly thicker oil, and it wouldn't hurt the seals to maybe do an OCI. It seems people here think you either have to use HM or conventional oil and that you can't go back after using a run of MaxLife or something whereas I think it might not be a bad idea to do a run of HM oil, preferably in summer, to take advantage of the seal conditioners...

I really like the Maxlife semi syn because it has a good amount of moly and it is really inexpensive at Wally world...Excellent oil that can be used in a new or higher mileage car.

If you have a specific problem, or set of problems, like high consumption, heavy deposits, or seal leaks, an HM oil is certainly worth a try.
Other than that, why bother?

High mileage oil is primarily to benefit seals. There is a slight cleaning, softening, swelling, and sealing benefit.
It can indeed help. Not always, but it sure can work.

But other benefits are a slightly tougher oil . More additives for longer life and sometimes better wear. Often they are a bit thicker than 'normal' oils - they are biased thicker in their viscosity range.

Use HM oil? It can't hurt. It may help.
I think there is a possibility that it can prevent seals from leaking in the first place [if they are getting old].
