I like the Sierra oil itself—works fine in my sedan—but I was frustrated with the shipping. It took over a week to arrive, so I had to wait longer than expected to change my oil. Product is solid, but I hope delivery improves next time!

Good performance, but pricey
Sierra's 10W-40 oil seems to be working well in my truck, but I felt it was a bit more expensive than similar oils I’ve used. Still, I appreciate the semi-synthetic quality and how well it holds up in hot weather. Just wish it was more budget-friendly!

Great oil for my car!
I've been using Sierra 10W-40 semi-synthetic oil in my car for a few months now, and I can definitely feel the difference. The engine runs smoother, and there's no knocking sound anymore. Plus, the gallon size is super convenient for multiple changes!

Not for my needs
I bought the Sierra 10W-40 oil thinking it would be a good fit for my vehicle, but after the first use, I noticed my engine wasn't performing as expected. Might just not be compatible with my specific engine type. Just a heads up!

Easiest oil change ever
Using Sierra 10W-40 made my oil change a breeze! I appreciate the easy-pour spout on the gallon container, no mess at all. My car feels great and the oil seems to last longer than what I had before.
