Hi,
I just bought my second Crosstrek a week ago, a 2015 2.0i Basic, w/a 5 M/T. I had gotten rid of my '14 Crosstrek a few months ago, and started missing it.
I've got well over 1500 miles on it as of today, taking it easy breaking it in. I just went and switch it over to High Test/Premium gasoline (92 Octane) today, and started noticing an improvement in performance, just like I did when I did it to my '14 Crosstrek, when I ran it in it. I'm not talking mind blowing performance mine you, but still noticeable. Done in two different vehicle can't be just my imagination.
The only draw back, a small loss in mileage. I estimate I lost about 2 mpg or so. I was getting around 35 doing 60 mph, w/regular, and now I'm getting a little over 33. I have to do more driving in order to confirm that.
I know some of todays engines, like the Ford Eco Engines for example, can run on either 87 or High Test/Premium , w/the High Test/Premium providing the better engine performance, thanks due to today's computer systems in them.
The 2.0L engine in the Crosstrek and Impreza, has a 10.5:1 compression ration, making it a high compression engine. Most engines w/that compression require High Test/Premium fuel. With the computer system in the Subaru, one has to figure that it too can compensate for the fuel difference.
The reasoning I figure, Subaru is trying to get the Crosstrek and Impreza to meet a particular fuel mileage. In doing so, they use a very light weight oil, 0W-20, and a low octane fuel.
When it comes to the factory oil, I thought I read somewhere that the oil in the Subaru's 2.0L engine from the factory is a 5W-30. Anyone know if this true?
Anyway, has anyone else tried using High Test/Premium gasoline in their Crosstrek, and what's your feeling about it?
