[This review was collected as part of a promotion.] Just hear the name “Mobil 1” and you think and expect the best. This is no exception. I have used Mobil 1 on everything from the lawn mower to the motorcycle, in my truck as well as the luxury car. When others advertise their product, you may hear “ we are as good as” or “ we are similar to”. What does that tell you? Even the competition knows how good it is.

[This review was collected as part of a promotion.] I have purchased Mobil synthetic motor oil for my vehicles for years now, because it is rated to be better than conventional motor oil. It is formulated with additives that enhance the oil's performance. I have had zero problems with my engines.

This is a testament to what an incredible product this is... I happened to see a commercial stating that Mobil 1 can protect your engine for up to 250k miles, well I’m here to prove that and more! I bought my dream car, a 2008 Lexus IS 250 brand new in 2007 & I knew that Mobil 1 was going to be the only oil I was going to use as I have in all my previous vehicles. Well, today my old girl has almost 362k miles on her and still runs like the day I bought it!! Yes you read that right 362,000 miles!!! Now it’s become a challenge to see just how many more I can put on her, which shouldn’t be hard as I religiously use Mobil 1 every 5k Miles. So, THANK YOU Mobil 1 for allowing me to continue my high mileage adventures in my dream car!!! Here’s to the next 300k miles!!!

The 2011 Honda CRV I own is not known for its fuel efficiency. So I want to get the most for my money so I use Mobile 1 Advanced Fuel Economy. It also gives me quick starts on cold Nebraska winter days. I change the oil twice a year , and the engine looks like new when l looking into the engine with the filler cap removed. You get what you pay for here.

I just go with what the manual book says on the recommended motor oil for my brand new 2013 toyota camry back when they first came out with the new camry in 2013. I use the recommended 0w20 and have never went back to standard motor oil. If your owners manual says to use synthetic then i recommend you just go Full Synthetic instead of the JUST synthetic for all newer vehicles that are now starting to use more synthetic type motor oil for better fuel economy. There are a lot of different version of synthetic motor oils out there so make sure you get the right type of synthetic motor oil that is right for your vehicle. FYI if you're gonna use Full Synthetic motor oil type then it is recommend that you change your motor oil every 10k mile instead of the old 5k mileage. That is how good full sythentic motor oils are today as newer vehicles are leaning toward better fuel efficiency.

I have 2 Subaru 2009 Foresters that I bought new. Changed both of them over at 10,000 miles to Mobil 1 synthetic oil and Mobil 1 filters. From then I changed oil and filters at 10,000 mile intervals. Now both are at about 200,000 miles each and running strong. No smoke or engine problems.

I have used MOBIL 1 SYNTHETIC in all my Porsches (street and track) since the 80's, but that is another story. This story is about a lawn mower which I bought new and ran "wide open" as a residential "bush hog" for 32 years. I changed the oil every spring with MOBIL 1 SYNTHETIC and noticed each year the oil while dirty (because of the atrocious operating environment) the engine used no oil and performed flawlessly. I became fascinated at about 20 years when I realized this lawnmower was falling apart in every way, wheels, carb, housing sheet metal, studs and bolts backing out of the engine, it was a complete wreck EXCEPT: it burned no oil and suffered no mechanical failures after running for decades and thousands of hours wide open (wished I had a HOBBS). To say the least, I loved this mower, my friends and neighbors howled at my eccentricity, but I paid them no mind, I know and understand true devotion, PLUS I had an ongoing SCIENCE PROJECT which I was going to push (literally and figuratively) to its conclusion. At 30 years the mower deck was "fully ventilated" and was probably dangerous, it needed its third set of wheels and the whole affair was just simply "string and bailing wire". None the less, I was not giving up on "The Red Devil"...I had owned this mower half my life and I was beginning to wonder who was going to be the last one running. I had hoped to open the engine one day and examine the wear index. However, at 32 years my better half insisted that "The Red Devil" had to go. I presented it to a young ARMY vet (who had admired it from afar) with the understanding that he would only use MOBIL-1 SYN and contact me IF the engine ever needed to be taken down as I wished to see the mysteries within. In great solemnity he assured me he would honor the terms and nervously loaded The Red Devil it into his truck. I take great comfort in knowing that if there is a heaven for lawn mower engines, "The red devil" is holding court! I concluded years ago that The Red Devil's longevity was 100% due to MOBIL-1 SYNTHETIC. To this day, I can not hear a mower run without harking back to all the good times with The Red Devil. In spite of all my pleas, my attorneys say I do not have a case against MOBIL and have suggested therapy.

I have been using Mobil 1 for the last 30 years, both in the United Kingdom, London and here in Canada, Alberta, Calgary for the last 10 years, on all of my Toyota / Lexus vehicles. 0W-20 flows easily at -40C, which is what is required here in Alberta for maximum engine protection and rapid warm up from -30C / -40C. Better fuel efficiency around 2% increase in fuel economy..

Been using this and other Mobil 1 oils since 1983. Never had an engine problem. I have two Toyotas with over 300,000 miles and use less than a quart of oil between 5000 mile oil changes. Sold a Ford van to someone with 250,000 miles, saw him a couple years later, he had damaged the body, but told me that truck is the best truck he ever owned and was still using Mobil one as I suggested when I sold it to him.

Been using Mobile 1 advanced fuel economy in my Honda and Toyotas for several years with zero problems. I receive excellent fuel economy on all my vehicles , well above the EPA estimates. Very happy with this product as well as all other Mobile 1 products I use and previously used in vehicles and equipment.
