The average price for a jug of oil, and filter, - it takes 3.5 quarts - and car was new in 1995, when oil was a lot cheaper, let's say average $12 per oil change, times 110 changes, works out to about $1300 worth of oil and filters - works out to 0.6 CENTS per mile for the oil. For the GASOLINE, it gets 40 miles per gallon, which is about 6 Cents per mile.
So 6 cents per mile for gasoline, and 0.6 cents per mile for the oil. So, you want to save money on the OIL???? - like how much? 0.3 CENTS per mile??? by doubling the OCI. This car runs like brand new, the compression and power are perfect, and it uses ZERO amount of oil. I have seen similar car to mine, but not well maintained, and BURNING oil. To repair that car, would cost MORE THAN $2000 dollars, which is almost TWICE what was spent for the proper maintenance. So I firmly believe in FREQUENT oil changes, and for me, that means change it 3000 - 4000 mile intervals. My Subaru, according to manual, with severe duty, needs oil change every 3000 miles.
It is very penny wise and pound foolish to run long OCI. Like they used to say in the Quaker State ad - you can pay me now.... or you can pay me later. I would rather pay more for oil, and send the used oil for recycling, instead of having to pay for a new engine, just to save 0.3 CENTS per mile. Especially when the REAL COST of owning a motor vehicle is over 30 CENTS per mile, which is 50 times the price of changing the oil every 2,000 miles(averaged out from 1995 - 2010)
The "cost" of 2000 mile oil change, increases the ownership cost by 2%, but this pays for itself, because the engine does not need to be replaced, which means the oil changes are actually for free, and you are not stuck having to buy a new car, means you are a better steward for the environment. - cheers, Captain Klink.
Well said. That is why, in the face of all this environmental [censored]. An old 60's or 70's vehicle is FAR more environmentally friendly. It's already been paid for just as any older vehicle is. Buying one vehicle and KEEPING it for a VERY long time is the answer. Gas mileage really isn't a concern. For now.
