My 03 Camry with 2.4L topped 360000 miles this week engine gets the same milage as it did new. The car uses no oil between changes and when I replaced the cam cover gasket the engine was spotless inside. I have used the 5w-30 since the car reached 5000 miles.

My wife and I just purchased our own house. So with home ownership we have been thinking about how we can save money one of the ways is to start doing our own oil changes. But after going over the mileage and needing a oil change we stopped in at our local Mobil 1 and was greeted by the manager John who not only had his team give us a much needed change but did it with a level of customer service we thought didn't exist anymore . I am more than capable of doing my own oil change now that I have the space but after going to this clean well maintained well managed location I will defiantly be doing my oil changes there. customer service goes a long way in my book. thank you John and your team.

I have had my 07 Cobalt SS since new using mobil 1 since day one. The car was daily driven and drag Raced normally​. Now the Last​ few years mostly driven spiritually on the weekends and still drag Raced​. My car has all stock internals engine has never been opened car is over 100hp more than it came stock. Compression is perfect no engine blow by and never shavings in my filter. Mobile 1 has done an amazing job protecting my engine and wouldn't trust any other brand. 75,000 hard miles and my engine is as healthy as new. What else could you ask for! Thanks Mobil 1

Been using Mobil 1 5W-30 in my 2000 Pontiac Montana, which I bought new, since about 30,000 miles and noticed the brown staining from conventional oil at the filler area. The car now has 340,000 and I still use the regular Mobil 1, not the high mileage, and still do not have to add any oil between changes at about 7,500 miles. I do the changes when the Pontiac oil change reminder comes on. When I change the oil, I look in the filler port and the engine is still clean and no sludge can be seen. Engine has never been apart except for the 3.4l intake manifold gasket failure, common on this engine I am highly satisfied with Mobil 1 and use it on my '84 Buick Riviera Convertable and '09 Chevy Avalanche

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 !

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.

I noticed the difference between Mobil1 and other synthetic since the first time i use it on my 2013 Sonic, and now has 56k miles on the clock. The engine turn to be more smooth and quiet. I realize that this is the only oil that i trust. There might be other good full synthetic but i dont want to risk it, for me Mobil1 has proved it all the way.

I own 3 vehicles. A 1998 Chevy K1500 5.7 Vortec, a 2018 Ford Mustang 2.3 EcoBoost, and a 2016 GMC Sierra Denali 1500 6.2 Ecotec (0W-20). I’ve tested every major brand of motor oil there is on these vehicles and none of them came close to comparing to Mobil 1! I would highly recommend this product to anyone that feels like they could benefit from a strong and smooth engine!

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.

I switched from conventional oil in my Toyota Sienna to Mobil 1 5/30 at roughly 70K. I now know that conventional oil can cause sludge build up. Sludge is not a friend of any motor. I change my oil every 5K and also install a new Mobil 1 filter. My oil comes out a dark golden color--not black like the dyno oil did. The van actually uses no oil in 5K. It now has 130,000 miles on it and runs like new.
