I remember ‘99-01 all my cars were beaters and used oil. When Weatern auto went out of business in town, I lost my inexpensive source of decent sub 1$/quart oil. When that stock of 10w-30 and -40 ran out, I drove to Walmart for oil. I think Tech 2000 was $4.97 for 5 quarts. I was skeptical of the quality, nobody I knew used it, but it worked just fine. Pennzoil conventional was my boutique oil if I had extra cash, but usually I didn’t. I remember when the name changed to Supertech, the price went up, and I again was skeptical. About that time, I could afford the Pennzoil and turned my nose up at the Supertech.
