What engine have you run the most? And roughly how many hours do you think you would have on it?
Probably an EJ22 with ~ 9,500 Hours
I had to look this up , its a Subaru motor car ?
That's what Google turned up for me as well Bruce.
I did some quick math and if 60 miles equals 1 HR. Of driving time...that auto has a whole bunch of miles under its bonnet 🙄👌
