Am I really ruining my engine by doing this? (chip, mileage, gas)

The fact that the oil still has it's viscosity at that change cycle is also a good sign that it works.

Of course, it's part of the story that no ones in their right mind over here would use anything other than full synthetic on a 1996 or newer. My own is a 98 and has always had full synthetic. Engine runs smooth as silk, even now, when it's technically overdue for a change.

And $$ is more scarce? I live in the second richest country (per capita) in the world. You'll make $70-90K a year working a warehouse, so I'd say we're good on money.

Yes $90k a year sounds great, but how much is taken out for taxes?

There are two separate issues here. One is at what point does oil break down, and the other is at what point does the oil contain enough contaminants to accelerate engine wear.
When I was working for Ford, they did a test of oil filters and found almost all oil filters become restricted and begin to bypass at about 1000 miles of normal driving. From that point on you are accumulating significant amounts of metallic, and other types of contamination in your oil. While it is true that synthetics can hold up longer (5000 to 7500) without breaking down and loosing viscosity, they are still becoming contaminated if you are not changing your filter. For the extra $5 I would change my filter at least once if I were going for extended oil change intervals.

Not that I don't believe you but a source or two would go a long ways towards making this claim believable.

As it stands now this claim is open to question..........

Sorry, I meant the recent oil change thread on here. I did read some wildly outlandish claims, not that I would try them on my own car though.

An even better question is what is the exchange rate? $90,000 Norwegian kroner is about $15,000 US dollars.

$15k would be considered fairly poor here in the states.

Going off topic here, but a decent chunk, depends on a few things though, but between 28 and 40%

But for that you get (pretty much) free health care, full pay on sick days and for a full year if you need surgery etc.

Money deposited into a pension fund.

5 weeks paid vacation a year, minimum. (By law) You also don't pay taxes on your vacation pay, and only half tax in December.

So on and so forth, bottom line is this: We got it good.

Well if you think about it, it makes sense. Cars that don't have the oil changed ever will eventually start to burn oil. As long as you replenish it fully you can pretty much go on perpetually running the car as there will be always fresh oil in there. At some point it will equalize.

Until you look at the exchange rate...

We don't use $ bud, we use NOK (Norwegian Kroners), I already did the exchange, in Norwegian money it's 530.000kr

90.000 is USD

Change your oil tightwads!

Tightwads? Ha! How about actually being smart with your money? There is no reason to change your oil every 3,000 miles, especially with synthetic. You're throwing your money away. I check my oil at 3,000 miles and it's still golden brown. Even at 5K it isn't completely black and the car runs like a champ. In fact I was told by my shop that the inside of my engine is the cleanest they've ever seen and that the engine is healthy as a horse.

My dad's Acura goes 5,000 miles in between changes and has 31,000 miles on it.
My Hyundai goes 5,000 miles in between changes and has 134,000 miles on it.
My mom's Lexus goes 5,000 miles in between changes and has 110,000 miles on it.
My friend's BMW goes 5,000 miles in between changes and has 147,000 miles on it.
Another friend's Audi goes 5,000 miles in between changes and has 92,000 miles on it (and his computer tells him it's a 10,000-mile change interval).
Yet another friend's Ford F-150 goes 5,000 miles in between changes and has 62,000 miles on it.

Still waiting for that serious trouble....
