Engine oil Castrol or Shell

Rotella T6 15W-40. I’ve used it in all my bikes, cars, lawnmower. It’s the best option if you own lots of motors. Just change it frequently.

Now they use castrol power 1 ultimate 10w50

I talked with my friend who works in skoda dealership as mechanic, he told that castrol edge is the best motor oil for these mk 3 models because it comes from factory with it. They have run tests on Petrol and diesel engines and best for these engines is edge, because it's made for these engines.

Castrol Edge LL.

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

I've been running Rotella t6 and a wix oil filter for years on my 04, 3k miles everytime, and it's currently still running with 245k miles.

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.

Castrol makes a Edge Euro 5w-30 and 5w-40 that is LL-01 and ACEA A3/B4, it's not going to meet the later LL requirements because it's higher viscosity and not as fuel conserving, also not low SAPS so potentially it could contribute to more intake valve buildup

Had my gle350d 4matic oil change garage used Oil Designed for Ford cars believe it was A5 castrol

Nearly 3000miles later engine rattled. On stripdown found shell on crankshaft had welded to crankshaft. Eng report it was shell  slippage.
