Isn synthetic oil expensive?
While the up-front cost will likely be $20-30 higher, synthetic oil can help save money in the long run. A vehicle designed to operate using 0W-20 synthetic oil typically has fuel economy ratings about a half-mile per gallon higher than a similar vehicle using mineral oil. Assuming 20 mpg as the base and $2.50/gal for gas, this could save $30 every 10,000 miles on most models, which is the distance between oil changes. So, fuel savings alone can help repay the added cost of the oil. Disclaimer: 2010/2011 Tacoma 4-cylinder and 2010 4-Runner 4-cylinder with engine 2TR-FE, while synthetic oil vehicles, have oil change intervals at 5,000 miles/6 months. Also, if 0W-20 is not available, 5W-20 oil may be used, but all vehicles must be replaced with 0W-20 within 5,000 miles/6 months.
