In Reply to: Anyone use Mobil 1 10W30 synthetic oil? posted by Tom in Boise on Wednesday, December 04, 2002 at 11:58PM :
I once worked with a guy who owned several six-plex apartment buildings. He had a 'compnay' truck that he used the synthetic oil in. I don't remember what brand. He said he only changed oil once a year, but he changed the filter every 3500 miles and added more oil to compensate for the loss. Had over 200,000 miles on it and it never went out of the county.
