Looking for some opinions here...
I have a 2012 Cruze LT - Auto.
I bought it August 2015 with 50K miles on it.
When I first got it - MPG was 34-36.
Drove it to Florida Jan 2015 doing 80+ on the expressway and got a very solid 32 mpg.
I have had it to my dealership 3 times for check engine light. The 2nd time they ended up replacing my turbo and the last time was for the waste gate pin/seal.
Within the last 2 months I have noticed a drop in my MPG - it is now 31 no matter what I do.
My driving habits - since day one it has always gotten premium gas.
I drive 100 miles round trip a day for work - only 14 miles of that is expressway - the rest of my drive is 55-60 mph with the cruise set.
I have tried fuel injector cleaners and they don't do anything.
Car is currently at my dealership right now and they are looking it over.
I know it doesn't see like a big deal - but with the miles I put on it, it adds up.
I would think the new turbo they put in it would have IMPROVED my fuel economy - not made it decrease.
Any one else had this issue or think they may have any ideas?
