We get asked this question all the time: “I just got a new Tundra and I want to treat it right – should I use synthetic oil? If so, should it be full synthetic or synthetic blend?” The answer: It depends.
Synthetic oil has fewer impurities, better properties at high temperatures than natural oil, slightly better viscosity, and it’s more resistant to breakdown. Therefore, synthetic is better for an engine. However, whether or not it’s better for your engine depends on a few things…
NOTE: If you’re rolling in a 2010 or newer Tundra, you’re probably using 0W-20 oil, which is only available as a synthetic. This is the oil of choice for newer Tundras mostly because it improves fuel economy. It’s some of the best oil available, and unless you’re doing something really extraordinary, sticking with Toyota’s recommended 0W20 is best.
