[This review was collected as part of a promotion.] Ok, maybe 'life-blood' is a little bit of an exaggeration. It is true, however, that your engine relies on lubrication so all those metal parts move freely and your investment(vehicle) gets you from A to B. I've been using exclusively Penzoil Platinum 5W-30 on my vehicles for almost.

[This review was collected as part of a promotion.] I regard myself as someone who is not a rookie/novice do it yourself but not a expert. I'm always learning things and working on my own cars is 1 thing I love to do. I've used this brand in the past when going to a shop but now I do it myself and it has never gave me any problems!

[This review was collected as part of a promotion.] I have switched from regular oil to synthetic one last year and I will never come back. It saves so much time, money and labor work. I use the Pennzoil oil for both my truck and my wife SUV. I do all the oil change so it's great to experience the big difference this oil can make. The cars run smoothly and nicely. But the most important is it takes less time to change oil for each car. Before I used to change at least every 3 months, now I can wait till 9 months or a year depending how much I drive. Like I said earlier, after using synthetic oil, i will never go back to the the regular one anymore.

[This review was collected as part of a promotion.] I used this to change the oil at home in my car and had no problems using it. The jug has two areas you can use as handles which is nice so you can tilt it all the way to get it all poured out. It has my car running great just like it should.

[This review was collected as part of a promotion.] Pennzoil is the best oil out there. It has yet to let me down and everytime I've tried a different oil, whatever machine I'm using the other oil on doesn't seem to last as long. Pennzoil guy for life!

[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 use the Pennzoil Full Synthetic oil for my F150 super duty and have the bets performance. This oil goes a long way and easy to change out. I used 6- 1 quart bottles. Easy to pour, I seem to never spill when using the little ones.

[This review was collected as part of a promotion.] The oil is good to change. I did a partial clean and not a full flush, and feel the quality of Pennzoil is better than other generic oils to use in a car. I am satisfied with the quality of the product and would recommend it.

[This review was collected as part of a promotion.] This oil lasted longer between oil changes. I also noticed my car drove a bit smoother and feel a lot better overall. I’ll keep using this oil since my car is sounding a lot healthier and I don’t have to change the oil out as often.

[This review was collected as part of a promotion.] This oil works great! Car runs well. Pennzoil has always been a good quality company and one I can count on for knowing I’ll have a good quality oil in my car. It works great and car runs well. Easy to change.
