PennzoilPlatinum High Mileage Full Synthetic 0W-20 Motor Oil, 5 Quart

I have used Amsoil gourmet oil and just about every other brand you can buy off the shelf. There are only nominal differences in these oils. Any modern synthetic oil will perform well and these oil companies buy their additive packages from the same handful of suppliers. They just use slightly different "recipes". Your car will probably rust out or crash out before the engine dies from old age. Right now this oil is about the best bang for your buck of the name brands. Just change your oil and filter at least every 5,000 miles and use your favorite motor oil that is in spec for your car and you will be fine. Motor Oils suffer heavily from marketing hype.

I recently switched to Pennzoil Platinum High Mileage Full Synthetic 5W-30 Motor Oil for my 2019 Cadillac XTS, and the difference has been remarkable! Here’s why I’m giving it a full 5 stars:Superior PerformanceFrom the moment I started using this oil, my Cadillac’s engine has been running smoother and quieter. The oil’s full synthetic formula provides outstanding lubrication, which is evident in the improved engine performance and responsiveness.

Pennzoil Platinum High Mileage oil is specifically designed for vehicles like mine. The enhanced additives and conditioning agents rejuvenate seals and reduce oil consumption, which is perfect for keeping my engine in top condition.Leak PreventionOne of the standout features of this oil is its ability to condition seals and prevent leaks. Since switching, I’ve noticed a significant reduction in minor leaks that were previously an issue. This has given me peace of mind, knowing that my engine is well-protected and less prone to leaks.Fuel EfficiencyAnother fantastic benefit I’ve noticed is improved fuel efficiency. The low-friction properties of this oil contribute to better gas mileage, which is always a welcome bonus. Over time, I expect this to result in significant savings on fuel costs.Cleaner EngineThe advanced cleaning agents in this oil help keep my engine free from sludge and deposits. This is particularly important for maintaining engine health and ensuring long-term performance. My mechanic even remarked on how clean the engine looked during my last check-up.Worth the InvestmentWhile Pennzoil Platinum High Mileage Full Synthetic 5W-30 is more expensive than conventional oils, the benefits far outweigh the cost. The superior protection, improved performance, and peace of mind it provides are well worth the investment.In conclusion, I highly recommend Pennzoil Platinum High Mileage Full Synthetic 5W-30 Motor Oil for anyone with a high-mileage vehicle, especially a premium car like the Cadillac XTS.

My car seems to idle better when using this oil. I like the high mileage additives. It really works to clean heavy deposits in my engine, and even functions well as a parts lubricant in my shop.The jug is leak free, the oil is a light color, the container seems durable which is great if you need to store it long term.This is a quality product by a reputable company that has been around for a very long time.

Great price, works awesome.

Pennzoil has always been the best oil for automotive, heavy equipment, air cooled, marine, rough service, and high performance applications. A high quality oil with excellent lubrication. I have seen engines in cars and pickups that have used nothing but Pennzoil last for 375k to over 500k+ miles. Pennzoil has an oil for everyone. I use Pennzoil in everything because I trust their products. Over the years I have always called Pennzoil technical on the phone if I had any questions and they have always suggested which was the best choice for my application.Here is a myth that upsets me. People think Pennzoil will sludge an engine. As long as you are using the correct oil for your application you will have no problems. All of the oil related problems or failures I have seen were caused by a person making the wrong decision. Don't believe me ? Go ask Lake Speed Jr about oil he is more knowledgeable than me.I have no leaks, no oil burning, better milage, great oil pressure, easy starting, and the engine I am running this oil in has over 170k miles on it. The engine has ran Pennzoil for fourty years and I changed from conventional, to conventional high mileage, and now to this new formula. Before choosing I was told by Pennzoil technical this would be best choice for my application.As for cost Pennzoil has always been a little expensive. I know that in the long run I save money and a lot of headaches by choosing Pennzoil.

Great product just wished they would stopsending this to me as i stopped my subscription long ago and they keep shipping and charging me.

Second Best oil for the price!
