[This review was collected as part of a promotion.] These are the perfect oil bottles to use to fill up my lawn equipment with . I have tried using the big jugs and it just makes a big mess all over my garage . I run a lawn business on the side and have multiple pieces of equipment that take 5w-20 full synthetic oil . I've always used the pennzoil oil with my lawn equipment and it's been the best choice . I used these bottles of oil in my weedeaters, edger, hedger, pressure washer and also my generator . This product hasn't failed me yet

[This review was collected as part of a promotion.] Pennzoil is the only brand oil i use in my Ford f150. Pennzoil full synthetic oil last a lot longer than almost all other brands of oil. It also makes my truck run smooth and helps the engine run better. I highly recommend this oil.

[This review was collected as part of a promotion.] I've always used synthetic oils in all my cars for the extended oil change interval and better protection against viscosity breakdown. The Pennzoil Full Synthetic is just as good as any of the more expensive options like Mobil-1 or Castrol. Oil changes are a great way to keep a car running for a long time and with this oil, I'm not worried about being a few hundred or even a thousand miles late for an oil change.

[This review was collected as part of a promotion.] This Pennzoil Full Synthetic Oil is high quality, affordable, and made by the best in the business; Pennzoil! I love the design of the bottle as well for a nice even and smooth pour. The additional handle comes in handy when putting it into the funnel.

[This review was collected as part of a promotion.] I got this and I change my oil and use this and so far has given me great miles without any problems. It is a very good oil to use and it is very expensive but it is a very great product. I will definitely recommend this to everyone that i know and i will continue to use this from now on.

[This review was collected as part of a promotion.] I decided to use this in my 95 explorer since it has trouble with dry start and I can say this definitely helped out during the heated days. Oil seems to keep the same protection as 5w20 but flows much easier for that old oil pump. I’d definitely recommend this to anyone having a slight lifter tick.

[This review was collected as part of a promotion.] What can I say but Pennzoil has been and always will be my number one choice of oil for all my vehicles! It's always kept my engines running smooth and has never let myself or anyone I know down. I will continue to use it for every vehicle I own.

[This review was collected as part of a promotion.] Cleaner pistons, better fuel economy, made from natural gas not crude - what's not to love? The 5 quart bottle is convenient to both use and store in my shed for future use. This is the only synthetic oil I will use for my portable generator in Florida to help keep it ready for emergencies.

[This review was collected as part of a promotion.] Protection of my car is my most important thing. I always need the best. Since switching to full synthetic I always go with this brand. I always change my oil as well. So I know it is done right and done well. My car runs better with this oil. I am thrilled with it.

[This review was collected as part of a promotion.] I bought this oil for my 2016 civic after learning how to cahnge my car oil myself. We have been using this brand since my cars first oil change at 5k. Never had a problem, never burns or low after 5k hard city driving.
