Been using this oil in all the vehicles since new. Usually buy it in the 5 quart jug, but with the $10 off coupon this was a bargain I could not pass up.

Use it in all three of my vehicles, 98 F150, 98 Lincoln Mk VIII, 2005 Explorer. Definitely helps keep engine internals clean. Been using this for over 10 years, no complaints

I use this on a higher mileage car that is showing signs engine wear Mobil 1 helps quite the engine noises the best. Definitely a high quality synthetic oil.

I bought this a few months ago and have no idea if this oil is better than any other oil however I keep using it since it is what the user manual recommends.

I started using Mobil1 in 1989. Back then I was still working and received free in house oil analysis at no cost as an employee perk. The results were obvious. I now use Mobil 1 in all my vehicles, six now which includes 2 Corvettes.

I’ve been using Mobil1 oil in my cars, trucks, SUVs for over 30 years and couldn’t be happier with its performance under all environmental conditions.

Due to the cold weather, I changed the oil in my back up generator from heavier oil to 5W30. I shopped around and Sam's had the best price. I ordered it online and picked it up the following morning.

Great deal on Mobil 1. I was buying Amazon Basic full synthetic, which is Dexos approved, but started getting. valve tap at 4500 miles. So it’s Mobil 1 for now on. Plus it was about the same price

Always expect a quality lubricant, my last vehicle made it to 246,000 miles with no issues before the transmission died and left me with a motor ready to go. Thus I am a firm member of the mobil 1 family for all three of my vehicles currently.

Bought the 5 qt container during Black Friday deal for $20ish. My Ford Escape takes 5.7 quarts, so needed an extra quart. Will keep an eye out for sale prices on individual quarts for subsequent changes.
