Mobil 1 5w30 EP Oil Case 6x1 Qt Dexos

Used in my 2011 Silverado Chev truck since new.Last year I started using in my 1968 Buick Skylark Car.I bought the car new in 1967 I was 18 years old.This was the first time I put Synthetic oil in my old car.

Mobil has a vested intrest to not over promise.Its in my intrest pay more because i dont want oil related repairs .I wonder if the drain interval will just get you thru the vehicle warrenty? . What would be a drain inrerval that yeilds 300k protection ?

We have 260k miles on our 2004 Corvette and have always used Mobile 1. I'm at the point where I change the oil when the oil life monitor is between 0%-5%. I was able to do this by doing oil samples and when one would come back saying there are still additives in it and I can go longer before a change. I've gone as long as 10k miles between changes. That saves me money and the car is still protected.

Most amazing oil. I have used these in my fleet of minivans for over 15 years now. I noticed the EP (Extended Performance) version went from a guarantee of 15k miles to 20k now. I do push the limits on oil changes and have gone over 15k many times. Some of my vehicles have over 200k miles. They all run perfectly. A good check of how much protection your oil has after 15k miles is to rub it between your fingertips and if the tips have some resistance you can feel that it is still protecting. The viscosity is the key to knowing if your oils needs to be changed. If you rub your fingers together and it is not slippery feeling the oil is not doing much.

Mobil 1 has kept the engines in my cars running like new and my cars are not new. I'm a car guy and maintain 8 vehicles with Mobil 1 for me and my family (six drivers). This includes a van, five SUVs, a sedan and a high performance sports car. Years range from 2001 to 2015 and odometers range from 35k to 250k. No engine failures, oil leaks, or burning of oil. If for some reason and oil change is extended due to the vehicle being remote than this is the oil you want in that engine, I never worry about Mobil 1 letting me down because I've used it for over 25 years. I'm a F1 fan and my favorite team also uses Mobil1

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've been using Mobil1 synthetic oils for over 20 years. The engines out last the car bodies. Never have had any internal engine problems. If anyone swaps from another oil and you do your own oil changes, be warned that you oil is going to come out as black as coal. It will be like that for 2 o 3 mobil 1 oil changes, 3 new truck I had dealer change oil 2 times on each because it was free service. All 3 trucks took a couple oil changes before it got all the sludge and dirt out. Running 10k miles between oil changes. After 2-3 mobil changes the oil starts coming out the color of dark honey.

Extended Performance 5W-30 gives me a feeling of confidence. I change oil, filter (Mobil 1), and rotate tires every 5000 miles. Mobile 1 Extended Performance has my engine covered in the event I go over a few miles since it is rated for 20,000 miles

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 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.
