Pennzoil Ultra Platinum Full Synthetic 5W-20 Motor Oil, 5 Quart

Many full synthetic oils out there but you can't go wrong with Pennzoil Ultra Platinum. Have been using it in my vehicles with no issues. Change my oil every 5,000 miles. It's Dexos1 GM Gen 3 approved and has less Parts Per Million (PPM) of additives then other oils which have to add additional additives to get Gen 3 approved. This means the base oil of Pennzoil is better without adding the additives to get Dexos1 Gen 3 approved. Gen 3 means you have great protection and a cleaner oil at the base level. I know, too much tech talk but you're basically getting a better quality oil for the price. With any oil you use, change it at the very least based on your owners manual. Changing the oil is key to protecting your engine and providing you years of operation.

I purchased this so I could service my vehicle and was perfect for the job.

I always recommend this oil to anybody who wants an above average quality of oil. I use it in my 5.7 hemi and it seems to make the motor run quieter and more smoothly. Can't really speak to fuel efficiency much, but it doesn't degrade the efficiency or performance. Not the best value oil by any means, but for anybody wanting top tier stuff, I recommend this.

Not only did my hemi's valvetrain quiet down using this oil over whatever the dealer uses but after watching countless independent oil comparisons, shows that this oil ranks right up there with some of the most expensive oils on the market. I've also had used oil analyzed after 6k miles and according to the lab, the oil still had about 20% life left in it.

Great oil,gas savings due to better fuel mileage. Stays cleaner long than regular synthetic oil i used. Still change at 4000 miles, but alot cleaner. Use a good filter also.No leakage in engine with over 165,000 miles.
