## NHTSA's summary

You may have seen news coverage related to oil consumption in Subaru vehicles. Oil consumption is an inherent feature of all internal combustion engines and the rate of consumption can be affected by such factors as transmission type, driving style, terrain and temperature. Our internal data shows that very few of our owners have experienced above\-expectation oil consumption, much less than 1% of Subaru vehicles overall. As the data in the article shows, we have continued to develop our products and our data suggests that this already low rate has been further reduced. The Subaru owner's manual includes a normal consumption example of 1 qt per 1,200 miles, and most owners will experience consumption at lower rates with normal driving. However, if an owner feels they are using more oil than they should be, retailers will assess the situation on a case by\- case basis and can perform a consumption test to determine what actions should be taken. Different drivers in the same car may experience different results. However, Subaru will continue to offer assistance to customers who feel they are experiencing above\-expectation consumption.
