[n00b on demand]

I will be heading to Toms house saturday morning for my front seal replacement and a couple of other misc things to be done. My oil leak has gotten worse....im putting a little oil in everyother day to keep the level at full. I know on the highway it will leak more because of the rpms. Should I stop inbetween somewhere at a rest stop and let it sit for 5 minutes and check the level? There is supposed to be a big noreaster coming this weekend...I hope to God i dont get caught in it on the way home.
