[This review was collected as part of a promotion.] It's a great full synthetic oil from a brand you can trust. So, the results are perfect, as expected! Great packaging for the shipping, impressive results! This oil will keep my car's engine running nice and smooth for the years to come.

[This review was collected as part of a promotion.] I wanted to start using a full synthetic oil for my vehicles. I wanted a name brand that I could trust. I have used Pennzoil for 45 years. I have used it in every vehicle that I have owned. Changing to synthetic oil for me with the amount of travel I do now yearly makes sense. Going longer between oil changes and the heat protection it will provide are the key reason for the change. Convenient six pack is right for me.

[This review was collected as part of a promotion.] I switched over to this Pennzoil Full Synthetic oil for my older riding lawn mower. It's better for the engine and I love the fact I have to change it less frequently. My mower seems to run smoother since the switch. Pennzoil is a brand I trust and will continue using. Highly recommended!

[This review was collected as part of a promotion.] This is a great oil to treat your engine to if you have never tried it before. It was able to make my engine in a relatively older car run noticeably smoother than before. I was surprised at the noticeable increase in efficiency.

[This review was collected as part of a promotion.] We use this oil in our Subaru Forrester 2010, it really helps the engine run smoothly. Our car has over 125K so it does burn some oil, and it is always nice to have this on hand to top off when needed.

[This review was collected as part of a promotion.] I got the Pennzoil Full Synthetic 5w-20. If you change your own oil this is the oil for you. Pennzoil Full Synthetic motor oil is made from natural gas which makes it much more pure than oil made from crude. It is proven to provide better protection and lasts longer than oil made from crude. Compared to other oil Pennzoil works great on my 2008 Dodge Ram pickup with high mileage .I would definitely recommend.

[This review was collected as part of a promotion.] I used this for an oil change recently. As far as adding this oil it poured well and as far as oil goes it had a good color to it definitely a quality oil. So far seems to be working well. First time I have used pennzoil and I'm a fan.

[This review was collected as part of a promotion.] I use the Pennzoil Full Synthetic on my Chrysler Town and Country. It’s the only oil I would ever put in my vehicles. It’s the perfect consistency. Pennzoil Full Synthetic Helps me get the most out of mileage for my car. It keeps my van running great and clean with no issues. I can go a lot of miles before I have to do an oil change. I also noticed my car doesn’t burn the oil like it used to with non synthetic. I highly recommend Pennzoil Full Synthetic for a great quality oil.

[This review was collected as part of a promotion.] Have been running this in my 2014 Wrangler (145k+ miles) since we reached 75k+ and couldn't be happier. Long lifespan and has been great in preventing other engine issues and usually get at least 4,000 miles per oil change

[This review was collected as part of a promotion.] Pennzoil Full Synthetic 5w30 case of 6 is very convenient and a bit cheaper to buy than buying 6 individual. We have several vehicles so need to buy a lot of oil. Best oil we've bought in a while its quality is superb
