Hey guys, has anyone had the Subaru upper engine treatment done on their GT?
Its the one where they put that bottle of octane/alcohol stuff on the car and run it and heaps of white smoke comes out when it cleans the engine.
I remember doing it on a car ages ago, but I was wondering if anyone has done it on their GT and if they noticed a difference.
And how much did Subaru charge you?
I have my 75k service coming up now and would like to get it done, as well as everything else.
Regards
Mick
