100% confident engine is protected to the maximum extent. Much cheaper to change oil myself vs Lube Center - - and I know it is done right and knowing full synthetic is used.

Have used mobile 1 full synthetic engine oil on my car for many years and been very satisfied. The car now has got over 240k miles and still runs smooth.

I have used Mobil1 in my 1996 corvette since it was new (also factory fill) i have never had to add oil between oil changes and never had an oil leak. As an ASE Master Technician, I can recommend it over any other oil i have ever used!

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.

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.

Great motor oil, have always used it. Giving it 5 stars even though the delivery was short two box's Erika in customer service was so helpful with getting the problem resolved.

I have used this oil for years and it satisfies my car manufacturer's recommendations. A perfect match. I have changed my own filter and oil since I was a boy.

Have used this synthetic motor oil for at least 25 years, with excellent results in engine longevity and efficiency. There are many available but Mobil one is the proven one.

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.

I’ve been using Mobil 1 for quite a while and i feel like it’s keeps my engine protected. I know the corvette racing team uses it and with the stress those engines go thru I think it will be perfect for my cars and trucks.
