I used Rotella T and T6 in my 1994 Land Cruiser for years but now have a 1988 Celica with 150,000 that I just bought. It calls for 5w30 winter and 10w40 summer. Any reason not to use T6 5w40 Rotella T6 in it year round? Or should I find a PCMO for it? It leaks oil but I haven't figured out where its coming from yet as I only had it for 3 days.
Rotella T6 in 1988 Celica?

If you want to do it correctly use the Rotella T6 0w40 as it is rated as SN, but realistically your cats are probably toast by now anyway.
Your 30 year old owners manual is pretty much obsolete. You can run any 5wx year round without any problems. Your decision on 30 wt or 40 wt is your decision and not worth having another light vs heavy discussion ( boring). Alternatively you can use a High Mileage oil to help condition the seals.

Rotella T6 will be just fine for it.

I suspect you're seeking some form of "best" ...
Don't ask. Rather, why not experiment and inform? Run some used oil analysis with each, and if your results are "normal", then all is well. There is essentially zero chance that you'll be able to prove with reasonable credibility that one lube is "better" than another. Given your cold area in winter, I recommend a year-round lube; I suspect the 5w30 PCMO will do fine.

3S engine ? It'll run another 30 years without changing the oil that's in there. Proven to run on anything you give it.
Cats must still be fine as it passed emission test with no problems even with dirty oil and dirty air filter.
Its just a $1500 beater car. Back when Rotella 5w40 was just called T, it sealed up many of the oil leaks/seeps that the Land Cruiser had and reduced the oil consumption it had using other PCMO's. But if a high mileage oil will condition the seal as well as Rotella T does/did then I will just use Valvoline Maxlife or similar to see if it will slow the leaks.

Switching to a 15w40 HDEO ( Shell Rimula R4X ) reduced leaking to almost none on my '88 Escort, and stopped smoking and oil consumption, i could not believe it, the car had a Motul 20W-50 in it before!
Right now i'm running a mix of that plus some 20W-50 to thicken it up a bit, i'm sold on HDEOs for life.

Conventional Rotella is now called T4. Semi-Synthetic Rotella is T5 and Full Synthetic is T6. Only 0w40 T6 and 5w30 multi-fleet T6 is rated as SN but most would not care.

There were not many choices in 1988 when the car was put on the road.
IIRC, 10w30, 10w-40 and 20w-50.
Not knowing what it was all about, I used to put 20w-50 in my 1982 celica at that time.
So, I don't think the car care.
Unlike popular believe here at BITOG, the car does not have a soul that can tell you whether it likes a certain oil or not. LOL.

My Land Cruiser told me very quickly that it didn't like M1. It used 1 qt of in one tank of gas with hard/throttle floored driving. Switched to Rotella and usage went to 1 qt in 3000 mi with any and all types of driving. That was at 220,000 mi on motor. I tried many oil in the Land Cruiser and the only oils that the motor didn't burn/use was Rotella T and and in the 350,000 mi to 460,000 mi range, Liqui Moly MoS2 and or T6 (which ever was cheaper) with Liqui Moly Motor Oil Saver added.
