98 LeSabre it's a good condition. It's just over the years,it's all stop n go....conventional turned all thick n black. Engine wasn't liking it. Changing it,fresh dino,it lived it,ran so much better.but with group 3 synthetics, it was much more durable an oil. It wasn't in as bad shape as conventional
SO I was woefully bad at guessing! Should be 3800 Series II engine in that. I took care of my mother's 95 3800 engine many years. That wasn't a short tripper and saw mostly Castrol GTX dino. As stated above, color isn't a reliable indicator. Might want to think about a UOA or simply use a synthetic for 3k runs.
If it were mine I'd change the PCV. Pretty easy on the 3800 and cheap part. This car sounds like a good candidate for an HPL cleaner run.
