I have 2 high mileage vehicles(05 Tacoma 4.0 @120k & 07 Highlander 2.4 @150k). No oil leaks or consumption with 5k oci of M1 Super. Should I switch to a high mileage formula?
 
Only if a)you want to b) it starts leaking/burning oil.

It wouldn't hurt to run High Mileage oil now. If anything, it will condition your seals and prevent future leaks.

Have you had any used oil analysis done with your current oil?

Absolute bunk. At least now I know where some of these old wive's tales that will not die are coming from.

I don't know of a single oil manufacturer that mentions "seal swellers" anywhere. Plenty use "seal conditioners", some of which even recommend they are fine for use in a brand new car.

I do agree the 75k thing is just marketing though. Most here probably don't consider 100k all that high of mileage any more.
 
Our 2008 Liberty with 80k on it will get Maxlife Nextgen 5w-20 next time.

Before that, It was regular Green bottle nextgen 5w-20.

Also Our 2003 Ford Ranger 4.0 runs Maxlife Nextgen 5w30 with 170k on it.

Neither Truck uses any oil worth mentioning with no leaks.

That's a load of nonsense.

I've switched back and forth between regular conventional and high mileage oils several times over the last few years in a couple of different vehicles. I purchase whatever brand name is on sale when I'm ready to change, and I don't care if it's high mileage or not.

None of the vehicles that have been switched back and forth have any consumption issues (or any other issues for that matter).

Trust me, I won't take your word for it, nor will I take the word of some YouTube nonsense.

Mostly marketing hype to get more money from consumers. If you have a specific problem, address that problem. Your engines are doing great with what you've been doing. Continue.

What's M1 Super? Is it Mobil 1 or Mobil Super 5000? Whatever it is, if you have no consumption issues, I'd keep doing what you're doing. Switch to a High Mileage oil when you need to.
 
I've debated this with myself before. I ended up switching our 04 at about 100k, and just switched my 06 this change. I see it as a preventative measure. Give it the extra seal conditioners before they start to leak, plus the extra detergents etc. It's all how you look at it.

With seal leaks it is a little bit of a roll of the dice. If the seal has just shrunk, the seal swell additives in Mobil 1 High Mileage can actually help re-swell the seal and help to reduce or stop the leaking seal. If the seal is damaged or worn, then it will continue to leak and will get worse with time.

+1, I'd run it for at least one OCI then go back to your regular brew if you want. When I noticed the Accord consumed a quart of oil I topped off with MaxLife and never noticed anymore consumption after 40k miles. Which is when I sold it.

When you call and speak to them, they advise it is perfectily safe for new vehicles and it's actually conditioners not swellers.

As others have said, do not using until you have too. If there is no consumption/leaking keep doing what you are doing. Besides, 120K really isnt high mileage, IMO anyway.
