Just a thought about our local Jiffylube here in Hawaii...a person I know had his vehicle's oil changed at Jiffylube somewhere here in Hawaii...I don't know which one and I'm not saying all of them are bad...just to be careful and like Coralkillah said, to watch them. Anyway, on with the story... this person had his oil changed and he drove off without a worry in the world. As he drove he heard his engine knocking or sounding weird...he pulled over and found out that whomever changed his oil, forgot to fill up the oil and it was almost empty! I admit, I wasn't there to actually see the dip stick but needless to say, he doesn't go to jiffylude anymore...so just be careful and like alot of people mentioned on this forum, changing oil yourself.....priceless!!!!
