Unthinkable oil proposal

Just sitting in there, corrosion occurs and your oil will not be as good a lubricant because it won’t just be oil that is being pumped throughout your engine on startup.

And for crying out loud, if you invested in a sports car, you made a commitment to owning a complex piece of machinery, and that requires maintenance. And that costs money.

So suck it up, and drop a $100 on an oil change.

I’m sorry, but if $100 every six months is “wasting money”, then you should not have invested in the car in the first place.

Ride a bicycle.

And lube the bike chain.

you realize I hope, that the oil and fuel in the oil boil off when you drive it right? If you did a used oil analysis, you'd realize that the amount of water and fuel in a car with no mechanical issues is very minimal.

I left the oil for 14 months in my Audi after driving it 3K miles not driven much. After a year with fewer than 5K miles, I changed it and looked brownish. It is a turbo and I use 100% synthetic. I wil never go over 1 year without changing the oil regardless of mileage. I drive my P car less than 2K miles/year and always change the oil 100% synthetic M1 0-40W before storage--6 months in storage.

Change oil based on age; change filter based on mileage. Thats my $.02.

2k miles that filter hasn't filtered anything, but the oil has degraded some.

I change the oil on my bike every year before winter storage regardless of mileage. And then I change it after about 1000 miles of ride time in the spring. I change the filter on the bike every 4000 miles (Honda recommended interval). All my other engines (except the lawnmower) get run year round. I guess that puts me in the change the oil side of the argument.
