You can trust the PENNZOIL yellow bottle..clean, efficient , cost effective , best performance oil made for every car. Make sure you always ask for PENNZOIL BY NAME, YOU WILL GET THE BEST!!!

I have used Pennzoil in my last 4 vehicles and have never once had an internal malfunction. My previous 2 vehicles had almost 200,000 miles on them and ran perfect. I only replaced them because the bodies just couldn't outlast the engine.
