Well it most likely had oil changes with normal oil.

So why don't you take some 5w30 oil like Motorcraft, Pennzoil, QS, Valvoline (I think I have most of the colors covered) and a filter and do a 4-5k OCI.

Then see how it did as far as oil useage, how did the engine perform and sound. From there you can alter what oil to use.

I see NO NEED to put in a High Mileage oil in the car if its running fine with normal oil.

Just my thoughts...

No need to put a HM in but no reason NOT too either if that's what you want to do,,M1 has a boosted add pack(being a HM SL oil)better base, help clean things up and could be used year around with extended intervals. What kind of car/engine/service does it see???
 
What year, make, model, and engine.

Depending on the engine, I would do a short OCI(no more than 3000 miles) with Mobil 1 10w30 or 10W-40 High Mileage or Valvoline synthetic Valvoline MaxLife 10w30. I would use a Wix filter.

After that , I would use Valvoline 10w30 or 10W-40 Maxlife blend and a Wix filter.

High Mileage oil is more than just detergents. It has a better 100C cSt, better HTHS, more anti wear agents, more antioxidants, and for sure has seal conditioners.
 
well I got it to drive in the winter mostly but now Ive decided to spend some money on it and make a nice daily driver but the oil will be changed around 3500 miles and prob. just the plain white purolator filter
Its a 94 Dodge shadow 2.2L
I put a after market Oil pres. gauge and it was running 65 PSI cold on a 80 deg. day

im trying to get the most out of it I can b/c Id like to make it a CS clone on day then swap the engine out for a turbo one.

I know m1 says todo a few short OCI for 3K when you switch to their HM so after that how long should I wait to change the oil and filter

I'm with you guys, I'd be running a good conventional 5w30 oil in a 200,000 mile car. YB would be my first choice, or any good SM oil that's on sale. I'd keep the OCI to about 4,000 miles, and decide if a High Mileage oil is needed or a different grade oil based on my 4000 mile OCI results. JMO

If you want to do a few short flush changes that's usually a good idea most oil manufactures i think recommend it

what car/engine do you have??

From above;

Its a 94 Dodge shadow 2.2L
 
In my Jeep 4.0 with 180K now, I've run cheap Quaker State 10w30, Rotella 15w40, and GTX HM 10w30. Of all of them, it seems to run smoothest with the GTX HM. YMMV.
