i have used mobil 1 pure synthetic for almost 2 years now in my 2011 chevy hhr and have had no problems ,it has now 74,500 miles on it and doesnt use any oil i dont have to add any between oil changes . i would like to start using the high mileage but it is not dextos approved and after talking with a mobil rep i am going to the extended performance pure synthetic .

When I was much younger and running hot rods ('66 GTO and a '68 Mustang fastback Bullitt clone) I used GTX 20-50 and it worked ok in those cars at that time. As I have gotten older and, while my taste for fast cars hasn't changed, I now drive something a bit more refined, a V-12 Mercedes SL600 and a smaller V-6 Mercedes SLK320 Sport and I use strictly Mobil 1 5W-30 in both. Both cars run so smooth that at idle , and aside from the blurble of the exhaust system, you cannot tell they are even running. Mobil 1 5W-30 is the factory recommended oil for the SKL320 according to the sticker under the hood. The SL600 didn't have a recommended oil but I use the same 5W-30 in it as well. We also have a Ford Expedition with a 5.4 liter Triton V-8 and I figured that if Mobil 1 is recommended for a Mercedes, it's more than good enough for the Ford, too. I do all the maintenance on all our vehicles, except for any major repairs, and I change the oil and filter every 3,000 miles even though Mercedes recommends oil and filter changes every 10,000 miles. If you have ever owned a Mercedes and had to have major repairs performed at the dealership you know it can b e a rather spendy experience, so I would rather spend a little extra money on oil changes now than on major engine repairs in the future. Mobil, I absolutely love your product!

I’ve run only Mobil 1 full synthetic for the last 15 years in cars ranging from an 03 Mercury Marauder to the current build on a modified 96 Volvo 850R. I usually run about 5000 miles between changes. The inside of my engines have no sludge build up and the oil looks like clear honey on the way out.

I purchased a 2000 grand marquis in 2001 with 22,000 miles on it, changed the oil to Mobil 1 5W-30 fully synthetic oil and set it up on routine changes every 7500 miles. Today August 2019 I have 584,632 miles on it and its still running strong, with no major repairs to the engine. Oh yes, I went through many spark plugs, coils, belts, hoses and lots of tires but no repairs to the motor. I give this credit to Mobil 1 oil.

I recently changed to Mobil 1 from another synthetic oil in my 1987 Monte Carlo SS. It's got 69,000 original miles, very low for a 29 year old car. What I noticed right away was better oil pressure than I've had before. Not that it was bad, but it is increased. The car means a lot to me, & it's important for me to protect an old engine, even if it has relatively low miles. Seeing increased oil pressure is like a security blanket for me. I will stay with Mobil 1.

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 ;)

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.

Year after year and well into six-figure miles, Mobil 1 motor oil keeps the inside of my engines completely clean. I am confident that Mobil 1 will allow me to operate these same vehicles reliably for many years to come. As I write this review, we are forecast to have many more days in a row of 100 degrees or more, and I am confident that Mobil 1 will protect my engines through any and all hot spells.

I use Mobil1 5w30 in each of my three cars, an 07 Chevy truck, 01 Corvette track car and an 88 Corvette. I had the track car out this past weekend filled with Mobil1 and it ran smooth and cool all weekend. In fact I’ve never had an oil related issue with any of my cars. And I’ve used Mobil1 exclusively for approximately 10 years. The 88 Corvette was switched to Mobil1 about twenty two years ago and run like a top every time I drive it, which isn’t often anymore. So that car sits around a lot. Great product!

I have a 2018 Chevy Impala Premier & Chevy Colorado 4x4 4dr both with V-6 engines. I had the dealer drain the original oil and replace it with Mobil 1 5w-30 Oil. Previous vehicles had almost 325,000 miles each and I only used Mobil 1. I am a customer for life.
