Engine oil Castrol or Lucas

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.

B46 which is essentially a B48 engine. 105000km. Running Castrol Euro Car 5W30 in the summer and 0W30 winter. Live in Canada so the ambient temp can range from -30C to +35C.

Any 5w30 that’s c2 or c3 rated will do, that said I’ve heard negative reviews around the quality of castrol so maybe spend just a little bit extra and get something mid range, I use Fuchs Titan GT1 FLEX C23 5w-30.

Avoid. Tried it, it burnt off very quickly. Back to Castrol with my tail between my legs.
