Claims are just claims, no matter if they recommend 1000 miles or 12000 miles between changes. Let's see some REAL data, not just claims. I did some spreadsheet modeling of the amount of gasoline we would burn in 100, 000 miles, at various engine efficiencies... The results surprised even me. A car that gets 12 miles per gallon will burn over 8300 gallons of gasoline in that period of time, or more than $20,000 worth. A car that burns half that ( 24 mpg, which is not too hard to get) will save over 4000 gallons of petroleum during that period. About $10,000 worth. The difference between changing your oil at 3000, 5000, 75000, or even 10,000 miles reflects as a relatively small savings of petroleum. For example, if you change oil at 3000 miles, you use only 41 gallons of petroleum over that same 100,000 miles. If you change at 7500 miles, you use only about 11 gallons of petroleum. Now, if you really want to kick the Islamic oil interests in the cashews, do you do it by worrying about motor oil, or gas guzzlers??

Are you saying he's not going to change his oil for another half million miles, or that he's changed it more than once per mile driven? -- Pork: It's the other white flag! -- James Lileks

There has never been a single study that shows any benefit from 3K oil changes versus 5K-6K oil changes. In fact, all the oil analysis studies show virtually no difference in the contaminants or loss of lubricating properties between 5K and 6K. The marketing departments of Jiffy Lube love people that are gullible enough to change their oil far more than necessary.

The cost of gasoline, whether it's low or high, has no bearing on the fact that 3000 mile oil changes are unnecessary. You won't find any oil study anywhere that has shown a benefit from changing your oil so often. If you believe that 3000 mile oil changes are necessary, why not 2000 mile or 500 mile? After all, oil is only about $1.75 quart, and good filters are about $4. You can do an oil change at home for about $15. |
