[quote=”jeffrey” post=46315]What about the magnets on the oil filter thing? Is that something worth doing or just witchcraft?[/quote]
those were only useful when engines were made of ferrous metals, not so much anymore.

[quote=”SpawnedX” post=46266]You are free to do with your car as you please, but please do not suggest people do what and entire industry tells you not to do.
You change your oil because it gets dirty, and no oil filter is 100% effective. You also change it because the additives, such as the detergent, do still break down.
The engineers who made cars, including cars that take synthetic from factory, know what they are talking about. So do the companies who make the oil and all the scientists they employ. So do most of the technicians who have to deal with people who hold the crazy beliefs you just posted.
Here is what Royal Purple has to say:
“Royal Purple suggests adhering to manufacturer’s recommended oil change intervals for vehicles under warranty using its API-LICENSED SAE engine oils. With Royal Purple HPS, drain intervals may be extended to 12,000 miles (20,000 Km) or one year, whichever occurs first in street-driven, mechanically-sound vehicles. For guidelines specific to your vehicle, we recommend contacting our TECHNICAL DEPARTMENT.”[/quote]
i tend not to believe everything someone says when they are trying to sell you something, it’s in their best interest to sell you more oil, it’s how they make their money.
the oil does get swapped out just by changing filters and whatever the car burn so you are always adding fresh oil, the filter gets changed as normal so it’s still going to pick up most of the debris. but for the same reason you can’t put synthetic to break in an engine, because there is not enough wear to break in the seals. I do an oil analysis every year and the oil is indicated as good still.
as for the statement from royal purple, that is written by lawyers not engineers.

may i ask what oil you have in your car?
if its 100% synthetic (PAO or ester) i also heard that it doesnt break down and only gets dirty, but ive never heard of anyone NEVER changing it
most of the ‘synthetics’ on the market though arent true synthetics, they are blended group III (hydrocracked) oils[/quote]
i’m using royal purple in my car so it’s full synthetic, the dirt you see in the synthetic oil is the sludge getting cleaned out from the engine not the oil itself, after a few filter changes you see that it’ll become clear again, i use the fram filter for synthetic oil, and i tell you the oil is the same color as when it goes in.
here is a link if you ant an oil analysis done, run synthetic for a year then send off a sample, and see the results for yourself.

I’m sure people are going to disagree with me, but you don’t need to change synthetic oil, the oil companies tell you that for you to spend more money. just change your filter at the regular intervals and top up the oil and that’s it. I haven’t changed the oil in my car in 8 years and my car has 200,000 miles on it, with synthetic in your engine the engine wears less and the oil doesn’t really break down, and what ever particles you do get gets picked up by the filter, so you just change the filter and you are good to go. i learned this from a teacher i had in school to become an aircraft mechanic (he was the engines teacher) he never changed the oil in his diesel jetta and he had well over half a million miles on it. he told me that they never change the oil on turbine engines except at overhaul, they just top them up and change the filters. so if synthetic doesn’t need to be changed on a jet engine spinning at 50,000RPM, and running at high temperatures in a -65degree environment, then it’s fine to not change it in your car. if you don’t believe me you can run synthetic and when it is time to change your oil keep the filter and get an oil analysis done you will see that the oil is still good and there is very little wear.
as for switching over to synthetic oil on a high mileage engine, I agree with ETCG, you are going to get leaks and noise, you need those worn passageways packed with sludge to keep the oil pressure up, and to keep the worn seals from leaking.
