  • Excellent mainstream choice

Works great. No unusual noises, leaks or burn off. Engine is buttery smooth. Would use again if price is reasonable. Meets spec for my vehicle.

  • Good oil, even if it darkens too soon.
Size: 5 Quart Style: Full Synthetic Configuration: 5W-20
I have been using Mobil 1 products for years, and this Advanced Full Synthetic 5W-20 keeps proving why it is still a strong choice. The oil pours clean and clear, and while I did expect it to stay lighter in color longer, it does turn brown faster than I would like. That said, the peformance in the engine is what really matters, and in that respect it delivers. My vehicle runs consistently smooth with no overheating issues, even in stop-and-go traffic. There are also no strange noises from the engine, which speaks well to the protection this oil provides. Cold starts in the morning are quiet, and acceleration remains steady without any hesitation. ... show more

  • Saves a lot of money only changing the oil every 20,000 instead of 5000 miles
Size: 5 Quart Style: Extended Performance Configuration: 0W-20
This oil is a no-brainer. It saves a lot of money only changing the oil every 20,000 miles instead of every 5000. Great quality with plenty of blind studies to back up the 20,000 mile change interval claim.
