Mechanics have spoken once again: Mobil 1 motor oil is the overall best brand of motor oil in the United States, according to the independently researched and funded multi-year study from Frost & Sullivan. Since 2013, Mobil 1 motor oil has received the most No. 1 rankings as overall best brand of motor oil in Frost & Sullivan surveys, proving that year after year, Mobil 1 is the No. 1 motor oil.

Study finds Mobil 1 motor oil is the "overall best brand" for the third year in a row
"The survey data proves what ExxonMobil has known for 40 years – Mobil 1 is the No. 1 U.S. mechanic motor oil preference," said Herbert Steurer, PVL Brand Manager for ExxonMobil Fuels & Lubricants. "Mobil 1 has consistently delivered an exceptional product, and now it’s even clearer that you can trust your engine to the No. 1 U.S. mechanic preferred motor oil."

Almost fifty percent of the surveyed experts prefer Mobil 1 – a preference rate that’s nearly double that of any other motor oil brand. In this latest survey, a list of brand names was not provided to respondents, and yet Mobil 1 was still selected as "most prevalent motor oil" in nearly every category and region. "In a 15 point comparison chart between Mobil 1 and its nearest competitor, Mobil 1 led on most key points," added Frost & Sullivan Program Manager Stephen Spivey. "This is a strong vote of trust, considering that more than 70 percent of respondents have 15+ years of experience."

The survey also showed that use of Mobil 1 motor oil by automotive technicians has increased each year, while usage of the two leading competitors has dropped. A review of the data also revealed that Mobil 1 remained the No. 1 rated synthetic motor oil with mechanics in key aspects including "customer preference," "reliability" and "brand reputation."

In their own words: Mechanics explain high ratings of Mobil 1 motor oil
It’s not just the statistics doing the talking. Experienced mechanics offered these words of praise:

"I use it in race cars, and it holds up better than anything else. Keeps it lubed, no metal flakes and it doesn't break down quickly."
"I use the Mobil 1 full synthetic, because that's the oil that the car leaves the manufacturer with – and that's what my customers want."
"The quality of the oil is a lot better … you can get 10,000 [miles] on one oil change."
"I have been doing this for 31 years, and [Mobil 1] has superior quality to other brands, less wear on the engine."
"It's got an impeccable reputation. It's a highly refined, great product."
Surveying experts with extended industry experience
Qualified respondents were screened before participating in the survey to make sure they met requirements prior to full survey participation. Among Frost & Sullivan’s survey participants, 71 percent of auto technicians surveyed have more than 15 years of industry experience, and were only asked about the products with which they have personal experience. Additionally, 89 percent of the technicians surveyed work at an independent garage or repair shop. "This all continues to build on 40 years of brand name recognition and customer loyalty," said Steurer. "There’s a good reason mechanics prefer Mobil 1 – it’s simply the best out there."
