I have 4 automobiles i use Mobile 1 all of them. I have used this oil since 1999. Excellent product.

You cant beat Sams for Mobil 1 prices. I use this in my 2005 Suburban with higher miles. Great price, especially when it goes on sale.

The box came delivered all greasy with one or more of the bottles leaking out. It also came upside down by the shipping company. There wasn’t enough oil missing that we didn’t feel like returning it.

I have used this oil for years and have been very satisfied. I had been trying to keep to API - SL as that is what the manufacturer sells for my car - model year 2003 BMW. The last 5 qt bottle, purchased in that past 2 months or so, says the oil is now SM/SN [note that the spec on this web site, in several places, still lists this oil as SL]. I believe this means less zinc. This website says that Mobil Oil no longer sells an oil for my car so I am off to look for something else.

Always used Mobil 1 in my cars since my 1974 Chevy Nova. I've had many autos since then and will only use Mobil 1. Now I drive a 2012 Scion XB with 120,000 miles on it. Since 75000 miles I switched to High Mileage only because starting using about a half quart in 4500 miles. I use 5w30 and do not use any only between changes (5000 miles)

[This review was collected as part of a promotion.] Seriously the only thing I will use in my car! Vehicle has 200k + miles on it and it helps my car run great! I’ve noticed a huge difference in the way my car sounds and gas mileage has gotten so much better! Highly recommend if you have a high mileage vehicle!

I've used mobile 1 since I can remember. My Z just turned 202k. Been running mobil 1 in it since I purchased it with 25k on it. I'm very tentative about how I change oil as well, I drain, refill with new, run it for a few minutes to clean out what's still in the cooler, block & lines etc, because I just don't believe in dropping the plug and draining what's in the pan. Then after it's run with the new oil I drain it and use compressed air thru the oil filter Orpheus to completely rid every drop of oil remaining in the system. People poke fun and say I'm crazy, but they then wonder why my vehicles last ridiculously amounts of mileage never requiring repairs. I've done this with all my vehicles and it's proof that it works, and Mobile 1 products are what they say they are. Ive disassembled engines after running mobile 1 products and am always amazed how clean they appear internally. Laugh all u want about my method, but my odometer always tells the tale and dispells the haters. Mobil 1 products are the ONLY products I will ever use in my vehicles, hands down no question.

[This review was collected as part of a promotion.] Mobil 1 has a well-earned reputation in the motorsports world. Even though my Subaru isn't going on the track anytime soon, I still give it the best protection I can against wear and tear on the engine. I've always used Mobil 1 synthetic oil and just switched over to the High Mileage version now that I've hit 75,000 miles. I haven't had any issues in the summer or winter with this oil. The car starts right up in the coldest winter nights.

[This review was collected as part of a promotion.] Can't ever go wrong with this brand. I have been always using mobil one and really never had any issues. Recently, I've realized it is better to use the high mileage one if your car has over 100k milage as it has a different consistency than the regular one. Be sure to always do your oil changes on time!

I bought my '99 4wd, 4.0 Ranger in 2001 with 26,000 miles and I can't even start to tell how many fishing trips, deer and hog hunting excursions this truck has been involved in. This truck has had a steady diet of "regular" Mobile 1 for the better part of the next 134,000 miles with no problems. Changed the oil every 5-6 thousand miles. Oil comes out a little stained but that's normal though. Outside of the normal maintenance there has been no oil related issues, EVER !! Truck has no leaks and uses no oil. I have recently started using the High Mileage Mobile 1 and all is well within my engine. This Mobile 1 is GREAT oil, a little expensive, but compared to a new engine, it's a real bargain. I can"t imagine ever "running" anything else in my truck..Looking forward to another 160,000 miles or more of fishing and chasing deer and hogs.. Thanks for a TREMENDOUS product !!!
