sorry man, I'm not doing that. I meant a way I can literally check it, not do a hands on experiment.

 

bring it to a dealership and ask them.. in order to check for the things i posted i would bring it to the dealership and ask them to check it out for you it shouldnt cost a thing.. (time for an oil change n e way??) :-P

 

I just changed my oil on saturday..

 

well there goes the chance to kill 2 birds with one stone :-P ummm but yeah bring it to the dealership and just tell them what you've told us.... its only holding 10Gal, and its sapposed to hold 15.9.. what could be causing this.....
