The local Atwoods store has introduced their store brand oil Ranch Pro synthetic. It is made by Warren Oil Company, Inc. Available in 5W20, 5W30 and 10W30. Regular price $3.49 per quart, on sale now for $2.99. Seems like a good buy.
Olas, I am just a simple guy that follows this site. I have looked at Warren Oil's web site at www.warrenoil.com and looked at the oil they market under their brand name LubriGold Full Synthetic. And I realize that the Atwood oil may not be the same blend as the lubrigold. I simply do not know the answer.
