Make it easy on yourself,,,change it every 20 hours.

20 hours!! Give or take a few minutes!!! Drive oil every other oil change. Cheap Insurance!!!!

Every 25 hours with Mobil1, with all the Manatee Zones we have, I think it's good insurance.

you have got to be kidding me.......is this a serious question???? you mean to tell me that you can't take 3000 and divide it by 50? whoa! put down the bong Einstein....

I usually change the oil every 15 hours or so.

Ssherman, before you go and try to insult me I suggest you take a few courses in elementary math.... After all, yes I do need help with my math and I am by no means a math wiz, but I am taking Calculus right now... that's a little different than this division problem you have here tough guy!!!!!!!!!!!!
Hey JBK, isn't this great.... we don't even have to make him look like an idiot, just give him time and he does it himself....!!!!!!!!!

As for where I work you didnt hear I am in a new field now and since your life is so boring and you have nothing better to do than be intrigued by mine. I am sure you will be looking into it. So I will take that as a compliment.

As for you JBK i will deal with you this weekend.

Tbone Change your own ****&n oil, filters and fuel filters next time. Mr. I dont even know how to make a bed
