Same here, in the 80's GTX was the oil to use, and the first oil I ever purchased with my own money. I have not used GTX in many years, it was the old 20W-50 SG stuff last time I used it.
However, last week I put a modern API SN GTX mineral oil in my car, and so far I'm loving it. Running smooth and nice, plus a little bit more quiet than before. It was a very affordable oil too, that met the car OEM specs I needed.
It was GTX 15W-40, API SN, ACEA A3/B3. I picked up 5L plus an oil filter for a total of $20- That is the cheapest oil change I have done in years, but I still feel like I'm using a good name brand oil.
