Since 1913, long engine life is Pennzoil’s driving motivation and their offering of 5W-20 synthetic motor oil fits the bill. It’s hard to beat the performance and lifespan Pennzoil provides for the average price of their 5-quart bottles and their consumer feedback strongly supports our conclusion.
Castrol motor oil was originally manufactured both for automobile and airplane engines when originally conceived in 1899. John Alcock and Arthur Brown chose Castrol lubricants to complete the first transatlantic flight in 1919. Today, Castrol usually shows itself as the most affordable 5-quart option for automobile engines in need of 5W-20 oil.
Originally developed to meet the lofty performance standards of German engineering, LIQUI MOLY is well respected by performance chasers and those maintaining fine-tuned machines. They boast of long oil change intervals and high-quality additives. While it usually carries the price tag associated with German automobiles, their option for 5W-20 will not disappoint those willing to pay for the MOLY standard.
First introduced in 1974, Mobile 1 carries the highest reputation and consumer trust of all available oil brands. Not only did Amazon customers make more Mobile 1 purchases of 5W-20 than any other brand in 2023, but they also received the most and best reviews of all available options today. You can’t go wrong with this mechanic and everyday consumer tested option for 5W-20 Synthetic Motor Oil.
Valvoline has a long-standing reputation for producing high-quality automotive lubricants, and product reviews agree. They hold almost an equal spot with the reputation of Mobile 1 except for a slightly lower number of total customer reviews. Usually offered at a higher price than their reputable competitor, Valvoline touts high manufacturing standards and a national reach for shop-use of their oils. It’s difficult for anyone to say their offering of 5W-20 motor oil would be anything but a sure purchase.
