OT, but I'd vote oil. Remember, older cars, like VWs, didn't even have oil filters. They just changed the oil more frequently. Think of it this way, you could screw an empty oil filter canister on and run your engine for years and probably 100,000 miles with no oil filter in the can, but I bet you wouldn't get 10 miles with no oil in the engine.
I don't think that is a good analogy. Elsewhere on this site is anecdotal evidence that you can drive about 40k miles in a new car before it will seize up due to lack of oil. If you top it off, it will go about 70k miles. Changing the oil and filter regularly gets you from 70k miles to 300k.
The question is: if you were limited to say $750 for oil and filters over the life of the car, what oil and filter would you use to get the maximum engine life? Would you keep the oil in longer and just change filters or keep the filter on and change the oil? I know some will respond that they would not skimp on either, but this is theoretical discussion on bang for the buck. Should I start a new thread of this?
