If you are a little handy changing you oil on a cx is quite easy. I purchase a set of RV leveling blocks - they can be used as ramps and store easily. 4 bolts and the belly pan is off - drain plug is real easy to get at - filter is on top of the engine - so simple and save $$$ $60 and mine is done in 30 minutes using Mobile 0-40 syn and filter> There are detailed step by step instructions in this forum> go for it!
