allow your FD to sit for like 10 days in the garage without driving her?

I have heard that compression numbers does decrease as time passes by living the FD idle for a long period of time..

Is this a myth or fact?

 

that should be just fine. i've left it sitting for 2-3 wk at a time. 10 days should be no problem.

 

10 days shouldn't be a big deal..
