Fuel mileage on Gen 4 Swap?

Sat Oct 28, 2017 1:10 am

Just got my gen 4 swap done on my ST165. Just wondering what other people are getting fuel mileage wise... I need to put some mileage on it to really find out what mine does. If it gets better than 16mpg in the city, that would make me happy(ish). My old 04 Volvo S60R made about 16-17mpg.

My 185 averages around 20 mpg with the factory engine.

I can only imagine a newer better controlled engine would do better than that.

Gen4 swap on my 162 I was getting 15-20mpg. It all depends how heavy your foot is.

Seems about right. I'm getting about 18 with oversized tires.

I was getting the equivalent to 17-18 mpg with my fresh engine, mostly city and mostly with an enthusiastic right foot.
