tumbleweed 49

I have a 2018 3.6r and have no stability problems, I drive on long trips at 70-85 mph. I did change out the rasb to 20mm right after I bought the car so I don't know what it was like with the smaller stock bar.

I am not too unhappy with the LS2 Goodyears that came on the car, I consider them better than some other brands of original equipment tires I have had on previous cars. At some point I will replace them, probably with Michelin Pilot Sport which I have used on my previous two cars.

This link will take you to a page at SubaruOnlineParts.com. You will find both the 19mm and 20mm toward the bottom of the page. I ordered mine from them and had no problems. https://subaruonlineparts.com/legacy-exterior-accessories-c-240_406_408.html

I upgraded my 2018 to a 20mm bar (retained stock bushings) last summer and found it did decrease body roll in corners. I did not notice any difference during normal highway use. It is an inexpensive, easy to do modification that is worthwhile.

I had thought I would change mine, drain and fill not flush, at about 50 K miles. But in October I received a letter from SOA stating that the normal New Car Powertrain Limited Warranty had been extended to cover the CVT for 10 years or 100K miles. If Subaru has that much confidence in the CVT I think I will just leave the fluid alone. The letter said the warranty extension applied to all 2018 Legacy/Outback, Impreza, WRX, Crosstrek, and Forester. Older vehicles may be covered to some extent as well, see article below. https://www.forbes.com/sites/jensen/2017/07/07/facing-complaints-subaru-offers-extended-warranties-on-1-5-million-vehicles/#39652d4a79dc

OK maybe so, but how long does it take to learn and what happens when you have more than one driver and there are different driving styles? I did read an opinion on another site that said it takes a couple of thousand miles and averages the driving styles together. If that's true it could be learning its little heart out and we would never know it. Does the CVT learn new shift points and does the EMS change the throttle mapping? I can't think of a test we can do to find out what is happening. The only thing I have found so far is opinions and guesses. I too take it pretty easy on the car except when I am passing on a 2 lane road or entering a freeway in some locations, but I have not noticed the "confusion" you mentioned. I realize this is all academic and the car is going to do whatever it is programed to do, but I am curious.

I have seen a lot of opinions that the CVT "learns" shift points but no evidence. I think it doesn't learn at all but the EMS probably does and people think the CVT is changing. But I have no evidence for that either. I tried mine last week and if I put my foot to the floor from a dead stop (shifter in D) it will shift the first time at 60 MPH, then again at 70. I did not go any faster because I was in a 50 MPH zone. I think the RPM was around 5700 or 5800. If I move the shifter to the M position, but do not use the paddle shifter, the shift RPM will be about 6300. EDIT: Tried it again this morning and I detected a shift at about 45 MPH which would have been 1st to 2nd. The two listed above would have been 2nd to 3rd and 3rd to 4th I think. These are at full throttle in D. Speeds might be a little off because I look at the tach to tell when it shifts and by the time my glance has shifted to the speedometer it has changed.

Kind of bothersome at first but after a few months I pretty much quit noticing them. But I don't think they have any real value. Anything the fake shift points do the CVT could do just as well without them.

I push mine to the floor fairly frequently, when passing cars and entering the freeway. I have been driving it that way for over 10K miles now with no problems. It is designed to handle all the torque the engine can deliver so perhaps yours has a problem.

No, not a single one. Actually I could prove I sometimes buy M1 at Walmart.

Subaru products are probably just fine but they don't own a refinery. Their petroleum products, like those of all car manufacturers, are made by the lowest bidder. I don't know who that is at present. Amsoil doesn't own a refinery either but their products do have a very good reputation. I usually use Mobil 1 from Walmart because I doubt that Amsoil is worth the extra money.
