I first began using Mobil One synthetic motor oil for my 1994 Honda Civic, which I purchased new in 1993. At 150,000 miles I decided to check my valve lash adjustment. I took off the valve cover and inside everything looked like new. I couldn't believe it. I changed the oil and filter every 7,500 miles, and the valves were still within specs as well. Today I use it in both of our cars, our 2016 Volt, and 2010 Prius, in 0w20 weight now. I will never use any other motor oil then Mobil Synthetic motor oil.

[This review was collected as part of a promotion.] My husband prefers to change the oil in his car himself and he ALWAYS uses Mobil. We live in Portland, OR and the weather is all over the place (hot, cold, snow, rain). This is a reliable motor oil.

[This review was collected as part of a promotion.] I received this 6 pack of Mobil1 0w20 advanced fuel economy in the mail and it came just in time. My wife’s Honda runs the same oil but not synthetic. We did an oil change with this Mobile 1 synthetic and we really like it. The car seems to shift smoother and is a little quieter. Not sure about fuel economy yet cause we just changed it. So far we really like it. The synthetic part really smoothed the engine down. We will continue to use it. Thanks

I've run this oil in my Honda Civic for most of it's life. Even after 196,000 miles the engine still consumes no significant oil between changes (It never gets down to the add mark before it's time to change it). I change at 1 year or 10,000 miles which ever comes first. I used to always hit 10,000 miles between changes but in the last few years it's been about 7,000 to 8,000 between oil changes since I hit the year mark first. This is a great oil and I'll continue to use Mobil 1.

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.

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.

[This review was collected as part of a promotion.] I have been using Mobile 1 for years in all my cars. This Advanced Fuel Economy formula enhances your car’s fuel economy. I get way more miles on this synthetic oil and have never had any oil related issues. It’s known for running cool to reduce the engine’s heat which is why I switched to this after having heating issues in a car we had. If you want the best for your car, this is what you need.

To start off with, I’ve used Mobil Oil in every vehicle I’ve ever owned, and never rocks has it let me not my engines down. I made the switch from conventional valvoline to Mobil back in 2014, and ever since, have seen massive improvements in all my vehicles from the way they perform, and even holding oil pressures properly. I drive a old 93F150XL 4.9 that I’ve been rebuilding with over 274,000 miles and I can assure you, without this oil and regular maintenance as well as using Mobil approved filters, my engine would have big dust by now.

[This review was collected as part of a promotion.] The same great quality Mobil 1 has always provided. I have been using this style of oil for many many years, this synthetic oil can always be counted on to keep the vehicles in good “health.” The oil is the bloodline of your vehicle, I use nothing but the best, Mobil 1.

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..
