Great Oil at a Great Price

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.

Proven high quality oil!

I’ve been using Mobile 1 high mileage 5w30 for over 25 years. I love this oil. No issues nor leaks with my 2009 Tahoe LTZ @124k miles. I change oil every 5k miles.

#1 oil for my Tundra

This oil from Mobil 1 has my truck looking at 200,000 miles in the 22 years of it's life so far and still running like a champ. "You get out what you put in." This is the Best. Having it at Sam's club makes this choice easy and light on the pocketbook. Thanks Sam's club 😘

340,000 miles and STILL doesn't use a drop of oil

I used nothing but Pennzoil 20W-50 for decades in my W126 Mercedes-Benz S class and W123 E class sedans with inline 6 and V8 engines but once I started driving a Lexus/Toyota 2UZ-FE V8, I switched to Mobil 1. At this point, I'm now using the Mobil 1 High Mileage...and my GX470 is still going strong at over 340,000 miles!

Good motor oil

My girlfriend was so excited when the Fed-Ex man dropped off the box that had Sam’s on the outside. She thought it was some type of food that I ordered. She was disappointed when I opened the box up and she saw that it was motor oil. Good price for quality oil.

Good so far!

So far, so good. I've been using Mobil 1 for several years. Not any difference from the regular blend, as far as I can tell at this point. One thing I noticed after pouring it in, it is no longer carrying the SAE rating for my Chevy truck. Shouldn't make too much difference, I hope!!

The Oil to use!

I have used Mobile 1 for years in every motor I own. The proof is in results and I have a 2009 Chevy Silverado with 250,000 on it and all it has ever had is Mobil 1. I get the oil sampled once a year and the results have always been very good. I will never use another oil.
