[This review was collected as part of a promotion.] I have been a valvoline user for years but then I happened to try this Pennzoil Full Synthetic and I am I happy I did. I can just feel my Jeep running smoother. It starts with ease and runs like a champ and I will be sticking with Pennzoil Full Synthetic.

[This review was collected as part of a promotion.] Got this about a week ago to change the oil in my mom's car. Figured I had a little time, so why not do it myself? Use to do it all the time. Well, cars have changed since then, and it wasn't such an easy job anymore. Had to get some help...called in a mechanic friend to finish the job, and he and I both noticed the Pennzoil Full Synthetic has received excellent marks for durability and protection. It might be wishful thinking, but mom's car seems to be running better, just with the Pennzoil oil change added. Think I'll be changing all my cars to this product soon!!!

[This review was collected as part of a promotion.] I drive a 2008 and it has some issues, so I like to use full synthetic oil instead of conventional oil. The full synthetic oil I feel is just a better oil for my car. I feel it lasts longer and just is all around better. I use the same for my daughter's 2001. And Pennzoil is my preferred brand.

[This review was collected as part of a promotion.] This is my favorite oil. It out preforms all the other oil brands in my book. If you don’t get your oil changed every 3,000 miles this oil will help keep your car moving. It’s just the best in my book.

[This review was collected as part of a promotion.] I switched to this after using a competitor's full synthetic, and have noticed a difference in my higher milage car. The idle is significantly smoother, as well as engine noise has been reduced. I'm looking forward to harsher driving conditions this summer due to additional heat to put it to the test, but as of now, I have no worries its up to the challenge!

[This review was collected as part of a promotion.] I love Pennzoil. I like the fact that it is made well without contaminants in the oil like regular base stock mineral oil. Works great and all the applications that I used it in for my jeep wrangler and suabru. I've found that cars I've used other oil on have had engine troubles, while I can prove a correlation I do believe this to be related.

[This review was collected as part of a promotion.] I got this to use in my car that I mainly use to commute to work and back which is an average of 60 miles a day depending on my route, this brand to me is a well known name brand, which is trusted by me and a lot of others, so far I have no complaints using this oil and I have been using it for a couple years now, definitely recommend and a recommend brand

[This review was collected as part of a promotion.] I like the fact that it is better for the performance of my car.I also like that is made from synthetic base oils and in its manufacturing converts natural gas into a high quality synthetic base rather than crude. Better fuel economy

[This review was collected as part of a promotion.] My car only takes full synthetic oil so this pennzoil is a great oil for my car. The bottles were easy to open and easy to pour. I am sure I will get the full mileage out of the oil. The bottles can be recycled which is a big plus.

[This review was collected as part of a promotion.] I have used Pennzoil Synthetic motor oi in my vehicles for years. I have had good luck with it. I drive a lot of highway miles at high speeds and I believe that Pennzoil is the best choice for high speeds and longer driving times. I run 8000 miles between changes.
