Subaru Oil change interval information, per Subaru for the 2011 and 2012 models. This question continues to come up so I thought it would be good to post the information directly from Subaru below.
First of all I would like to point out the fine print.
“Proper oil change intervals vary with vehicle type, driving conditions, and the kind of oil you are using– conventional or synthetic. This chart provides recommended schedules for 2011-2012 Subaru Vehicles. If you have an older car, ask your Subaru Parts and Service Manager which oil and oil change schedule is right for you.”
What this means is the chart cant be taken as literally as you think with out knowing what is put in for oil and how the vehicle is used, notice there is no clear definitions anywhere or any other suggestions for intervals based on use, just the chart, you figure it out.
For every line with a conventional oil called out, understand that in most cases it will be a synthetic blend oil used and most likely Castrol 5w30 synthetic blend if done at the Subaru Dealer and many Subaru Independent Shops.
Differences for 2013 are that the only conventional oil changes are the 6 cylinder engines. Oil change intervals suggestions are a grey area, always have been and always will be, if you are comfortable with a different Interval by all means follow that schedule, just make sure you never starve the engine for oil if you stretch it out a bit.
Or this could be your engines fate.
Thanks for reading
