Oil Weight


Mobil 1 Extended Performance 5W-20 Motor Oil, 1-Quart is rated 4.9 out of 5 by 17.
Rated 5 out of 5 by from 302K and Still Ran Like New From first oil change to the last I used Mobil 1 in a Ford Escort from 1993 till 2005 while we racked up over 300K on it. I did the oil changes myself to ensure that only Mobil 1 would be used. The engine never displayed any lubrication issues whatsoever during my ownership of the car. That's right. No oil burning, no crank seal leaks and no perceptible increase in valve train sounds. Please allow me to digress a little further. My decision to go with Mobil 1 back then was based on an old Air Force study, published in 1978, holding that even with drain intervals increased to 25K (!) Mobil 1 prevented lubrication issues in the dump truck engines used for the study. Based on the information above I started using this extended product last year in our Ford Focus and have since put 13.2k on it with no issues at this this time. I will change it shortly. I think it fair to say that we can entrust our engine lubrication to this product.

Rated 4 out of 5 by from Mobil 15,000 mile oil Change oil once a year with this oil. Just the convenience of once a year use is fantastic and worth the extra money.

Rated 5 out of 5 by from great oil If you want to go 15,000 miles between oil changes, make sure your oil FILTER is also guaranteed to last 15,000 miles. This is very important!

Rated 5 out of 5 by from Highly recommended I am a parts counterman at a national auto parts chain. Myself and my family have been using either this product or its "cousin", Advanced Fuel Economy 0W-20, for the past few years now. We have had fantastic results from using them including confident cold weather starting and optimal gas mileage resulting from clean engines. I recommend these products to my customers whenever I can. In my opinion, this is the world's finest motor oil.
