Owner reviews for engine oil

Idemitsu to both, because it’s designed and tested on rotaries.

Pentosin is fine, Mobil 1 is fine, Castrol, whatever. I put Mobil 1 in my racecar but castrol in my daily because it burns oil and I want a heavier weight that I can't find Mobil 1 in. Pentosin or LiquiMoly are good, but don't put too much thought into it.

Been running Fuchs 5W40 lately, N52 with 130k kms

5w 40 liqui moly

I use Pennzoil Ultra Platinum 0W-20, and follow a 5K miles/6 months time change schedule. (It’s twice as often as is recommended but that’s just my personal preference on how often I change it, not indicative of oil quality or use parameters.)

Liqui moly 5w40. At 252k on my 2006 e90 n52

Pennzoil Platinum Euro 5W-30

5w30 liqui moly

Mobil 1 0w-40

I spent ages today on the phone to numerous SEAT dealers, VW dealers, SEAT HQ, VW HQ, Castrol and Millers. The bottom line is total confusion everywhere. I rang 12 SEAT dealers - all but one (I'll come back to which one)said that VW 505.01 must be (and is)used.
