I have used this oil for over 40 years my dad used the same oil. And I used it in my first new pick up truck and when we tore the oil pan off to check the mains and rods it looked like a brand new motor I had over 450,000 miles.The oil was changed every 2,500 miles the oil is great and I still use it in all 4 of mt trucks.

We have been using this in my Great grandfathers 1968 Cub Cadet since he bought it new. Original engine no internal repairs have been done and it mows 3-5 acres weekly along with winter duty such as plowing and snowplowing. Thank You Pennsoil for making such a great motor oil !!!!

I've used Pennzoil, in my truck, ever since I can remember, when my Father was a mechanic for Ford Motor Company. Even to this day, and always I will use Pennzoil...makes all my vehicles run smoothly.... love it..! I'm a big NASCAR Fan, of Joey Logano... and I love Fords... I would love to have this hanging in my NASCAR Room....

[This review was collected as part of a promotion.] Iv'e used Pennzoil all my life I can also tell that this product keeps the internal parts of the engine Clean . I know this because I have replaced valve cover gaskets on high millage engines that have nothing but Pennzoil used in them.

[This review was collected as part of a promotion.] I used this "plain" Pennzoil for years in a lot of mostly older cars, i.e., "beaters", and had really good results doing so. Everyone is so excited about synthetic oils these days, and while they are excellent, they tend to be quite costly. It's good to know that Pennzoil's "basic" product has been great for years, and has also been improved over the years. An excellent product at a reasonable price!

[This review was collected as part of a promotion.] I've been using penzoil 5w-30 ever since my first car back in high school. Didn't know much about cars back then so I actually went through a couple different brands before Pennzoil but once it made its way into my engine I was hooked. I love Pennzoil because it's not super crazy or complex, it just does what it's supposed to for my car engine & that's all I need. Trust nonother brand with my engine. Thanks! - Ron

[This review was collected as part of a promotion.] I started off using Pennzoil because Dad did but as time went I became a loyal user as I used and abused my 1970 'Cuda and the motor held up. I have continually used Pennzoil products in all my cars because when I buy a car, I like to keep it around for a while.

[This review was collected as part of a promotion.] When I was young I assumed all motor oils were the same. Then I put cheap oil in an old pickup. The engine was much noisier and I was afraid it would fly apart. I immediately went to the auto parts store and asked what they recommended. The counter guy was a weekend racer who swore by Penzoil. I drained out the junk oil and put in Penzoil. The engine quieted down immediately. I have used nothing but Penzoil for the last 35 years.

I have used conventional Pennzoil for years and currently have one vehicle with 260,000 + miles and one that pulls a 30 ft, 10,500 lbs 5th wheel with 155,000 miles on it. I have never had an oil related problem on ANY of my vehicles (current or past) with Pennzoil in use. When I had to do intake gaskets on the vehicle with 260+ on it because of a coolant leak, the lifter valley and inside the engine was crystal clean. Neither vehicle uses any oil between 3000 mile changes or has any sign of exhaust smoke. I will remain to be a loyal customer as long as you make a superb product.

I am in the auto parts industry and sell a lot of different motor oil. Options for oil are crazy, there are so many different brands out there! Well the choice for me was easy, because I've seen the Pennzoil name for a long time as a big fan of Steve Park, and now Joey Logano, I support the sponsors, and have not been disappointed yet! Only oil I put in my vehicles! Only oil I recommend!
