10k with good oil will be fine, that's only around 7kish miles, most synthetics will get to 10K miles now easily.

I use semi-synthetic in the daily driver and change at every 5K miles

Air & pollen filters at every 10K

Brake fluid every 20K or 2 years, coolant every 3 or 40K. PSF about the same time.

Currently using Castrol GTX, but normally guy whatever is cheap.

>change the oil in my sister's bmw
>the old oil is fucking black and the seal is wasted
>learn she hasn't changed the oil on it since she got it

Every day, I find another reason to be shocked this thing still runs.

about 400 miles ago. Mobil 1 syn 5w-40 and a wix filter. did plugs too.

I did it at a friend's house and the retard forgot to put the cap on the drain pan so when it rained a bunch later it flooded out and shit a bunch of my used oil all over his driveway ¯\_(ツ)_/¯

Every 4000km with whatever full synthetic oil is on sale. I drive a rotary.

A month ago.

Mobil 1

I only use Mahle, Mann, or Wix XP filters, and use whatever high mileage full synthetic is on sale. It's usually either Mobil 1 gold cap or Pennzoil Ultra.

My boss never changes his oil, he claims there is no reason to change the oil unless you overheat the car, he just adds more if he gets low. I attempted to tell him that idea is insane but he is convinced otherwise

A mechanic told me you're supposed to run conventional in rotaries.

Change nearly monthly since I'm putting down ~5000 miles a month. So I mix it up between Mobil 1 high mileage and extended perfomance depending on budget. This winter I might run castrol magnatec to see if "intelligent molecules" are a meme or not.

That is true, most synthetics have flame retardants in them that keep them from burning as easily as conventional oil. The oil that the OMP injects to lubricate the apex seals has to go somewhere, so if it won't burn it builds up around the spark plugs and fouls them, leaves a residue along the chromed housing and makes the apex seals stick, and exits the exhaust ports and damages the catalytic converter. Because of this, Mazda officially recommends conventional oil for its rotaries. There is Idemitsu racing rotary engine oil that is full synthetic, and it's safe to use because they specially formulated it for rotaries so it burns properly.

The other exception is if you have a Sohn adapter that draws 2 stroke oil from a separate reservoir into the OMP instead of drawing oil from the pan. That way the synthetic oil never has a chance to get in the combustion chamber to not burn.

I have it in my bike, changed it two months ago, but have been riding like crazy since, so gonna change it in a week again, since it is pretty damn black at this point
