YES, change your oil often...Chevron needs your money. It's darn tough to get by on 10 BILLION in ONE quarter. That's three months..do some basic math, the daily income will make your transverse colon implode. Their service stations are a thing of beauty.. one restroom, no air or water, no drinking fountain, etc etc etc. You can buy beer, wine, a Slurpee or a banana flavored condom, but nary a 20 amp fuse! Go figure. frown frown
