Noticed the last few days in a couple of Dollar Generals in my area that they now sell Peak synthetic oil in quart bottles, both 5w- 30, and 10w -30. The price is $5.75 per qt., but I noticed this morning that it is on sale the next few days for $4.95. Bought 4 qts. 10w-30 for my 2006 Elantra for next oil change. The sale price ($4.95) is pretty much what the local Walmarts here sell the Super Tec synthetic oil quart bottles for.
