[This review was collected as part of a promotion.] My dad has worked for a gas company named " The Hartley Company" they own many gas stations here in Ohio. I have grown up around all sorts of products, I'm sure you can imagine. However, I stuck with Pennzoil all my life. I have had many cars since then and still stand by the brand. I had a 302 mustang that I was Very hard on. After she wore out I made up my mind to rebuild her and the inside of her was spotless had no build up of any kind. Just to help out a little more this motor went through 4 transmission s before I tore her down.

Since I can Remember we have been using pennzoil either 10-30 or 10-40 depending on vehicle and weather temperatures, My father and i did our own oil changes at home and still duing it. When we lived in colder weather in the midwest we used 10-30 and when moved to Texas we have been using 10-40 on hot summer weather, on all our vehicles we have owned

I started using Pennzoil in 1966 for my car because my dad, an auto mechanic, used it. I am now 71 years old and have always used Pennzoil in all my vehicles, including lawn mowers, snow blowers, chain saws, etc. I have never had a failure because of oil, and usually get at least 150,000 miles or more out of cars. When people ask why I use Pennzoil, I tell them, for example, that I have always used it in my 15 year old lawn mower, it starts on the first pull and does not "burn" oil. I hope to get 15 more out of it!

[This review was collected as part of a promotion.] I have a Suburban with 240,000 on it and a Blazer with 208,000 and they both will be just off the full mark between oil changes. I use it in my mower,tiller and 8kw stand by generator and all run like a top. I just bought another Suburban and it will get Pennzoil. At one time I had a 71 Pro Street Vega with PENNZOIL in the pan. I am working on a73 Vega that will also get PENNZOIL Now with my job I even get to haul Pennzoil all over the USA .

[This review was collected as part of a promotion.] My dad would have been 97 this year. My childhood memories are the yellow quarts. He changed his own oil and had to have the correct grade for weather and temperature. Being the tom girl I was I hung out in the garage and watched/helped my dad. He was a fanatic with cars and taught me to ask for Pennzoil for my cars. I lost my Dad in 1990, I have saved some of his beloved tools that I was taught to use. I would love to win this tool box as a Pennzoil childhood memory to hold my Dad's tools. All oil is not the same Pennzoil every time! Still a tomboy and still insist on Pennzoil

WORKS THE BEST ,USE ALL THE TIME , ALWAYS THERE WHEN I NEED IT

I've used this oil for years and would never switch.

I have purchased other oils but always go back to Pennzoil!

I have been using this for awhile now and just love it! I have never had any problems!! Will continue use for a very long time!!

Got a 1986 Chevrolet 1 ton 454 Hardworking Truck Bought New and Use Pennzoil from the first oil change
