Subaru says - MPG est. 25 city - 34 highway. Your good. The MPG will increase 1-2MPG after the first 1000 miles of breaking in the engine.
That's right, and don't just hit the highways on a road trip, to properly break a new engine in it needs a full range of driving, city, country roads where speeds are constantly changing and then highways where speeds are at a set rate. Do it like that and it should break in just fine.
tennisshoes-. Interesting answer, I purchased my 2010 as a certified pre-owned car, has almost 82,000 runs like the day I took delivery over 2 1/2 years ago at 65,000 miles. Doesn't burn excessive oil, about a quart in 3,000 miles or more.
And, I'm getting 24 to 25 city and 29-30 highway depending on how it's driven.
They say that it is old school way of doing it, but from what I have seen from engines that were not broken in properly, I'm convinced that this the way to do it.
My Forester is getting over 26 in mountain driving. It has dropped about 1 mpg now that it has about 40k on it. My service manager that I trust says to break in new Subaru engines like you would normally drive them. The computer learns your driving habits and if you baby it for the first few thousand miles you may end up with a car that seems like it is down on power.
