Engine oil Castrol or OEM Audi

I personally use Castrol in all my vehicles, and if I buy used cars I preform an oil flush and start using castrol immediately.

In my 2020 A6 I had aral oil and it consumed 1l of oil in 15k km. Then I used castrol LL and now it does not consume a drop at all.

I like to use Castrol Edge Racing with the 278cc HPE2, made a big difference to running temps, top speed and effiviency.

I go for Castrol for BMW. Somehow this machine really likes it.

I’ve been using castrol edge euro 0w-40 for years and loved it. Seems to be discontinued, can’t find it anymore. That sucks, moving to mobil 1 euro 0w-40.

I run Castrol Power 1 in my KTM 350 4T. I'm just past 800 hrs with \~25hr oil changes. It meets the JASO specs my bike requires. I have not changed a clutch ever since I bought it at 280 hrs. I had the motor apart at 500hrs and the Nicasil bore coating was \*perfect\*. That was the last time I swapped out the piston.

5W40 Castrol

I use Castrol Edge. It's cheap and good. I drive a lot and I change oil every 3k miles so 5qt for $25 just fits my life better.

I do this on my Q5, I started using like half a quart of cheap new sacrificial oil to mix up the bottom of the pan and extract as much black oil as possible. I almost had an issue with the extractor tube getting stuck in the engine l, but I was able to get it out with a bit of force

Why do Audi’s burn through so much oil? One thing I don’t miss about my 2019 Q7 is the constant adding quarters of oil throughout the year.
