Engine oil RAVENOL or Mannol

For the UK, cheap and good: Mannol Fully Bi-Synthetic Engine Oil Longlife 3 5w30

The car runs well, no problems starting up, no significant oil burning.

Even Ravenol, which is pretty expensive since it is made in Germany from Group V base stock. Great stuff.

I use Mannol 7715 on my 3.0tdi

I used to have castrol but since i chiptuned my octavia i switched to ravenol and the oil temps went down a good bit and it doesnt use any oil but that could also be because the old oil was 0w20 and the new one is 5w40

Last month I replaced the valve stem seals and it helped massively with the smoke. It doesn't really smoke much anymore, there's definitely still small puffs when taking off quickly, but nothing that I can see in the mirror.

I go with 10w40 Ravenol TSi

I use the mannol 5w30, it might be cheap but it's still just as slippy

I use Ravenol which is 100% PAO base stock.

The oil i have run: VW brand, Castrol and Ravenol all 0w-20 that meets 508/509. Basically on cooler outside temperatures the oil does run slightly higher than on hotter days.

after 2000km of running on it, i see there is quite a drop (30% from the max point). i think that is very weird...
