Marc Graham, who is president of Pennzoil-Qaker State, owned Jiffy Lube International was quoted in 2001 Lubricants World interview as saying "AT(PQS) we use a number internally that if we (shortened the drain interval) by 100 miles (for each car serviced), it would an additional $20 million in revenue for the company." He also explained that "if we could move our customers to get one more oil change per year, it is worth "$294 million for the oil change alone and $441 million in revenue when you include the ancillary products and services customers typically buy along with the oil change."
Wow! Look who is getting the 3,000 mile rewards. If you don't believe big oil when you are filling your fuel tank why in the world would you believe them about the 3,000 mile oil change? They use their huge fuel profits on marketing the 3,000 oil change myth so they can make even more profit. They spend mega dollars on this and still make huge profits. As a friend of mine loves to say "Only in America" the rest of the world does not do 3,000 mile oil changes.
