Pennzoil 10W-40 Motor Oil, 1 Quart

The oil stays cleaner longer than any other oil I have used, conventional or synthetic! I'm totally impressed, my engines will last longer and have less problems using pennsoil as it cleans and keeps contaminants out of the engine! Awesome product, I can see why some customers vehicles have made to over 1 million miles!

used penzoil products all my life they can be counted in

I have been using 5W-20W in my 2013 Chrysler 200 for 6 years changed every 6,000 miles and my car runs very smoothly. High recommend Pennzoil.

I have purchased other oils but always go back to Pennzoil!

I always get this oil and am never disappointed. I simply ordered online and went to the walmart.com place in the store and they helped me the rest of the way. Thank you

I have used Pennzoil on and off most of my life. Was always my go to 30W lawn mower oil but after buying a Dodge Hellcat that uses the super premium Pennzoil synthetic I have become more and more of a fan. I recently purchased a used 08 Police Crown Vic with 140K miles. Was fleet serviced every 4-5K with records and the engine inside is still very clean, I don not know what oil was used prior to my purchase but it was changed as per spec. I had a dealer do my first oil change with recommended weight Synthetic blend Ford brand oil 5-20. Now 3K miles later I change to this tried and true Pennzoil conventional 5-20 oil and I notice the normal start up top end rattle noise is gone to almost gone. Strange, to actually hear a difference in a engine based on brand of oil surprised me after 40+ years of changing my oil especially moving from a blend to full conventional oil on a high mile engine. I remember my late father telling me back in the early 70's to always use a good Pennsylvania grade motor oil... Father recommended, Dad approved!

After running Pennzoil my engine seems to run quieter doesn't have that whiny sound...

This oil was bought by recommendation of the motorcycle that I ride. It's great oil.

Rolled 5500 miles on the current pilot change and the oil currently doesn't show any discoloration. I'm running this in a 2016 ram 1500 4x4 5.7 hemi. Mixture of weekend boat towing, country/hwy mileage. Current fuel mileage averages 16.8mpg

My Mom used this oil for yrs and yrs in her old Crown Vic 2 door, and thats all she would use The car life was extended forever she swore I believe her!!!
