Hey,
Just thought I would point this out. Was out with mother earlier at Ace Hardware and decided to explore there oil inventory.
The only synthetic I saw over there was Pennzoil Synthetic in 15w40 and I think 10w30 viscosities. I saw the Pennzoil 20w20 and thought of the Lab Reports at the LC website since it was mentioned more than several times, so it popped into my head. Just pointing it out,,,,,AR
