What brand of engine oil do you use?

[StockEngine]

Good evening. Any inputs and comments regarding Shell semisynthetic and fully synthetic engine oils? These are the only ones readily available in our town. Thank you.

the yellow and blue bottles are good and meet some api requirements. you should still change oil as per your vehicles maintenance recommendation ie interval and oil specification.
