Not only did the excessive noise disappear, after adding it in, the oil seemingly burned off at a lesser rate, 113,000 miles? I also have tried 0w30 entirely in either my MkVI Gli or the MkV and the burnoff seemed to be the same if not slower compared to Pennzoil Ultra 5w40.. 3.88 Hths.
Old dark grey bottle I could purchase in quarts from a Tuffy... Its Noack was around 6 percent...and had a PAO/GTL blend
Grey bottle had GTL very short period of time. That Ultra bottle was Group III mostly, before switch to GTL. I am not sure actually GTL was ever in that Grey bottle. Pennzoil is always confusing with PDS. I saw that PDS with HTHS of .88 and then they watered it down to 3.6cp.
But HTHS is not indication of usage. EA113 had fuel dilution issues too. That could contribute to loss.
