Engine oil RAVENOL or Motorcraft

'17 f150 5.0l with 150k running 5w-20 motorcraft. Not a single problem and this was used to haul a 12' steel enclosed trailer loaded from day 1 and the wind blows a LOT here. Doesnt use a drop of oil.

I have an Octavia 2.5 vRS TDI and it has 450k km now, it only drank 5w30 and never an issue, not even in cold winters and I had a few -25 starts and it started right away, at the first key turn.

I run motorcraft in my mustang and have zero complaints.

I ran motorcraft for like 70,000km's and switched to amsoil 5w50 after that.

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

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’m using Motorcraft 5W-20 Synthetic Blend in all my Panthers with 2500 mile change interval and no issues.

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