Engine oil OEM Toyota or OEM Volkswagen

First 500-1000 miles is probably a good idea since there are likely metal bits left over from the manufacturing process and, although they get cleaned very well, the oil does a much better job of it and you don't want those bits floating around in yiur oil or in your engine itself.

After that, you can change your oil as often as you want as long as its under ~10k miles. Most people recommend 5k miles bc oil will pick up debris and metal shaving and what not and 10k is a bit long to let it go unless you're using a much higher quality filter like amsoil or Mobil 1. Most full synthetic oils will last longer than 10k miles these days, but I wouldn't push it due to the debris it picks up.

I got my first oil change at 1065 miles following Toyota Master Diagnostic Technician youtube personality The Car Care Nut's advice to do the first one at 1000 miles, and will follow a 5000 mile / 6 month schedule going forwards.

We haven\u2019t done anything but oil changes since buying it.

2008 VW Beetle is a 2.5 liter 5 cylinder. Yeah, 5 cylinder. It takes 6.3 quarts

I ran this exact oil in my late B5.5 1.8T, and it worked great, until some lady blew a stop sign, t-boning me and totaling my car. But it wasn't the fault of the oil, lol.

For newer vehicles I am in the camp of: if you want the car to last a long time use the 5K change interval with the exception being in the first 10 K. For the first 10K miles I would do 3 changes (not just 2) to be sure any debris/material from the break in process is cleaned/ cleared out quickly before it can potentially metastasize into a bigger issue (much later on);

Just do it every 5,000 miles. It’s the standard for most vehicles. Unless it burns oil often, then maybe 3000miles. I have a 2019 camry se and I’ve done it every 5k miles. It’s currently at 96k miles, oil still looks golden and brand new before I change the oil after every 5k miles.

The cars are very capable of doing 10k mile intervals between oil changes AS LONG AS YOU USE THE PROPER FULL SYNTHETIC! You won't get any problems doing it that way, however by 5k the oil will have a little bit of dirt in it so some people will do it at 5k just for peace of mind and to make 100% sure that the engine stays clean.

Just keep the right viscosity oil in it and monitor the oil temp. You might be able to read oil temp from you ECU through the obd port. 120-130C is very ok with good synthetic oil.

I blew up a VW polo with the wrong oil and high oil temps.

I don't recommend toyota oem fluid for hard driving because it seems to cook easily.
