I have used 5w-30 for our 2017 Chevy Malibu Premier 2.0l Turbo, and 5w-20 for our 2015 Chevy Colorado LT 2.5l engines since new. There have been no issues or oil usage on either engine, and the oil comes out in good shape when the oil meter tells us it's time for an oil change.; The oil changes come at 1 year for the truck and aprx. 10 months for the Malibu Turbo., and I feel these are very safe intervals with the Mobil1 Advanced Full Synthetic Oils. Thanks Mobil !

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.

1998 Tacoma, I used to drive this truck for 250miles/day, Using Castrol-GTX/3000miles. Soon as it reached 1500miles, gpm went from 20 to 17. I tried every things that people recommended on the internet to improve gpm. sparkplug changed every 25k-30kmiles(do not use Bosh Platinum, just OEM Nippon Denso plug). Nothing worked. Soon as I switched over to Mobil1 Sync with OEM oil filter. My truck drove better, smoother, quieter and gpm remain @20gpm until the next oil changed which is 10Kmiles. You can see the Viscosity of the oil remain the same, just darker. So I switched all my whole family vehicles(5 Toyotas, sedan-truck-van-SUV) to used this type of oil since 2000. Since I maintenance all vehicles myself, this 10kmiles oil change save me a lots of times and $$$$. Let me tell you an impressive story about this oil. I gave my son the truck for his college years, in 4year. When the truck did not run(because of the MAF sensor clogged), he called me to come checked the truck, there was no oil on the dipstick. DRIED!!!! Soon as I cleaned the MAF, I cranked the engine, it started right away. there is no issue with the engine. I still driving it now. over 200kmiles/24yrs still running like new. why buy new vehicles since mine run and looks like new plus paid off.

Been using Mobil 1 for years now. Ran engine development for Ford Motor. Tested Mobil oils at several different weights along with work to help improve them on the Aston Martin program. Engines were like brand new on teardowns been using ever since. Great oils

I used to use dinosaur oil and changed at 2000-3000 mile intervals. Back in 2012 I bought a brand new Camaro, v6, and it called for blended oil and it needed to be GM/Dexos approved. The price of blended oil and full synthetic was the same so why not go with full synthetic instead. I traded the Camaro off a few years ago for a '17 Colorado with basically the same engine and it will get Mobile also. I am such a believer in Mobile 1 that I now go by the oil life meter and now run until it tells me to change which is between 4000 to 5000 miles. I will likely be a customer for the rest of my life.

I alway ran Mobil 1 in my Vett. I was on Interstate in rush hour traffic and sucked a giant Target plastic bag up into my radiator. The car overhear! My oil temp went to 329 degrees. I finally got out of traffic and pulled the bag out. I got car cooled down and took it to my mechanic. The heat cracked two spark olugs, but the oil was fine! Changed the oil as a precaution and drove the car for 7 more years. Mobil One is my oil.

This week we had to take the valve covers off my 2002 Jeep Grand Cherokee Limited. Finally had a valve stick & kick off a rocker arm after 250,000 miles. I bought this Jeep in 2007 with about 50,000 miles on it, & since then it has had nothing in it but Mobile 1. When we took off that valve cover, the cams & all still look new! No gunk anywhere, just clean oil soaking everything. Thank you Mobile 1 for keeping my Jeepy running to a quarter million miles, & longer after we fix the current issues ;)

I purchased Mobil 1 Advanced Full Synthetic motor oil as a first-time buyer to this product and it is top-notch because my vehicle drives excellent and shifts great and as result: I am a fan for life with Mobil1 full synthetic motor oil and I do recommend this product for luxury vehicles, high-mileage vehicles, vehicles burns a lot of oil and sports cars.

I have a 2012 Silverado 4.8 with a few mods in the engine tune long tube headers and a camaro ss body throttle I was recommended by the guy who tune the truck and this full advance synthetic oil is amazing the engine runs way smoother and I got 117250 miles on it it responds way better now than it use to not only that I change to the mobil 1 oil filter that too is a good product I will highly recommended and there no way I change the brand no more on the truck. Mobil 1 oil and there filters are the best.

To me, Mobil 1 is by far the best oil to use in your vehicle. I purchased a 2003 Ford Ranger, 3.0L, 24K miles, the end of 2007, 4 + years old ! I changed the oil to Mobil 1, 5W-20 on the first oil change I did. The first thing I noticed was the engine appeared to run quieter ! Interesting. I can't say if the MPG improved, I didn't keep a record, but the engine did seem to run better overall. It is now 20 years later, still running Mobil 1, 5W-20, in the same 2003 Ranger, and the motor is still running great, no major repairs, starts every time I turn the key, still sounds great, you would never think I had the original motor in the truck. My secret is: 1) Full Oil/Filter changes every six months (twice a year - January and July). 2) Change the Filter in between the oil changes, three months intervals (April and Oct), and add Mobil 1 to top off the engine oil lost when changing the filters alone. 3) Start again Jan Oil/Filter change. It takes 4 Filters, Oil Filters of your choice, 2 Cartons of Mobil1 (six quarts in each carton, purchased at Costco, great price); 5 quarts of oil for the engine during the January and July oil changes, and an extra quart for the oil filter change (April and Oct). Simple RIGHT ! Cost: approximately $80.00 yearly. I know I could get far more milage on the oil... but more oil changes, is better in my book. Thanks for reading. NOTE: I am running Mobil 1 in my new Dodge and in my latest purchase a DR PowerEquip. XL30,20HP V-Twin Brush cutter, which I am expecting a long life on the motor.
