Any one try harvest King synthetic oil? Priced at $2.49/quart. Appears to be rated ok. https://www.ruralking.com/oil-rk-full-synthetic-0w20-qt.html
at 4 quarts every 10k, i'll stick with mobil one on sale. but hk might be just as good idk. btw, @a_gray_prius says you can get mobil 1 at walmart on sale and rebate from mobil brings it to around $2.50/qt.
The Petroleum Quality Institute of America identifies itself as an independent resource for information and insights on the quality and integrity of lubricants in the marketplace. PQIA PCMO Sample Summary List Finding a brand of oil that meets industry standards is easy. I don't see the long term advantage of buying substandard oil.
The dexos license number for Harvest King 0w20 full synthetic is GBI F0707121....this is identical to the dexos license number for Citgo full syn. 0w20....I would imagine this means the oils are identical.
