Mobil 1 is my go to motor oil for many years. This particular viscosity is used in a turbo 4cyl. AWD car and provides 10k miles of use before the oil change. Depending on time of year and conditions I don't always go past 7500 but I feel comfortable going to 10k if needed.

I have been using Mobil oil since the early 80’s love the product the only think I noticed with the extended brand it starts to turn a darker than normal color after about 1500 miles. I pair it up with Mobil extended filter as well. The most I run it for is 8000 miles and never the limit.

I bought a z51 c7 museum delivery first year & still have the car. Dry sump di motor, GM says use Mobil1 & that's all It's ever had. I change the oil once per year myself, engine still consumes no oil 9 years 78k mi later. Engine runs like new, 4cyl mode & all. 32 mpg at 70 mph. GM was right, Mobil1 5w-30. Thank you & Don't change a thing guys.

I have been using Mobil 1 for couple decades and it is still the most trusted product for my car.

I buy this 5w30 for my 2019 gmc 6.2L the 0w20 is garbage and should never be recommended unless you live in nome AK.

The only oil I use. Dozens of cars over the years and not a single oil-related breakdown. Also great for small engines like snowblowers and garden tractors!

Been running Mobil 1 for many years in everything from pickups to snowblowers to motorcycles! Keeps your engine very clean and cool. Not high priced like some of the so called premium oils. This is a premium oil!

How does one really know how the oil that they use is really good oil? Well, all i can say is that with using Mobil 1 for quite some time now, I've never had any motor malfunctions. Change it on schedule and use Mobil 1 and you're good to go.

I've been using Mobil1 in my vehicles and mobile equipment for over 15 years. 3k mile changes are just sales techniques. New cars can go 8k or more without needing a change. I have run 300k on a couple cars. I trust Mobil1.

I've been using Mobil 1 Synthetic for well over 10years. One oil change a year or 10k miles makes the life much easier, and all my cars run excellent - and this includes 3k miles Acura *practically new) or 90k G37...
