Has always performed very well in my vehicles since it was introduced years ago

Great product; good deal when on sale (only)

I love that I can buy the authentic Toyota oil filter at Walmart for much much less than going to the Toyota dealership!

Oil that could have been altered. The container left sediment at the bottom. The color was different from other cans purchased with the same viscosity. I share the data stamped 10225A31A RN6899. 517834 D330ABEA816

I'm a 46 year old man that was turned onto Mobil 1 oil from my grandfather, they used Mobil 1 in all their fleet vehicles! After using Mobil 1, I can honestly say... I have never had Any internal engine failure on any vehicle I have owned! I only & strictly use Mobil 1 & wouldn't change to another product! In my opinion... I use only the best!

I have a 2018 Chevy Impala Premier & Chevy Colorado 4x4 4dr both with V-6 engines. I had the dealer drain the original oil and replace it with Mobil 1 5w-30 Oil. Previous vehicles had almost 325,000 miles each and I only used Mobil 1. I am a customer for life.

Didn't know oil was dripping out the side of my oil filter. I had skipped my routine of checking oil, coolant, etc. a couple of times. When I did check my fluids found the dipstick dry.. I couldnt believe it! Ive been fooling around with cars all of my life and this has never happened before. I know wnough to say if it wasnt fir the lubricating properties of Mobil 1 Advanced Formula, I would probably be searching online for a new motor for my Ram 1500. I will use this oil for the rest of my time here on earth. I dont usually write reviews but had to on this one. Btw: added four quarts of oil then found the leak. No oil warning light, no symptoms of oil being that low. Scared the living daylights out of me! Thanks for making such a fine product Mobil 1. Im your new lifetime customer, for sure.

I drove for a limo company back in the 80's., and my boss used Mobil 1 in all of the vehicles, even his own personal vehicle. Back then even before the new extended performance oil he would change the oil every 15,000 miles. and never experienced an engine oil problem. I saw with my own eyes, these vehicles go 300-400,000 miles and still be running great when he sold them. i have used Mobil 1 products ever since.

This oil does what it says it can do. Provides excellent lubrication to the engine and increases fuel mileage. I ran the Mobil 1 5W30 for 15 years in my 1995 Ford Ranger 2.3 four cylinder. I bought it brand new. I changed the oil between 5000 and 8000 miles. But the oil can go longer if it needs to. The oil never let me down. I believe it also helped the trucks battery to last 14.5 years. Because synthetic oil is so slippery that it takes less energy to start a vehicle. Thus making your vehicles battery last longer. And when I owned my Ranger I was living in Michigan. So my truck saw 8 very cold Winters. Then I moved to Mississippi and the truck saw 7 very hot Summers. My trucks engine did great in both climates thanks in part to Mobil 1 5W30. As for engine cleanliness; the 2.3 has an oiI splash plate under the lone valve cover. I scratched off the black paint on it where the oil cap goes to promote to people how clean Mobil 1 keeps an engine clean. No sludge ever appeared on the scratches. Use Mobil 1 with confidence. It wont let you down.

Been a fan of a competitor for some time, availability led me to switching to mobile 1. Right away I've noticed smoother operation, which is debatable, but what isn't is the better fuel economy our vehicles have picked up. I'd swear our vehicles have more power and even running the air conditioning we get a 1-2 mpg improvement. So far, I'm very impressed!
