Found it today on my way at MCAS Miramar autoparts shop. Grabbed 5 quarts of GC for $4.68 per quart. "Made in Germany" on the back and Green oil came pouring out. After changing out my 5,000 OCI Mobil 1 0W-40, I drove for 10 miles on the new GC. I then check the dipstick and the oil now looks light brown?
