Reviews of Castrol engine oil

Castrol. I've just always used it. A bit of advice though, i'd recommend staying away from Pennzoil, I had to clean an engine out after using it. Nasty, waxy stuff.

Just did a major service using castrol 10w40 Maganetec with new Iradium spark plugs etc. Car is super smooth & pulls strings & no overheating.

I recommend 5W40 Castrol Syntec! Here's why: Smaller numbers = thinner oil. The "W" means "Winter" - or the viscosity of the oil when the engine is cranking, and first warming up. The 5W oil is very thin when cold. The engine will crank faster, the pump primes better. The hydraulic lifters in your 16v will fill up and follow the camshaft better and with less noise. When you are at operating temperature, the 40 weight oil will give you the protection that a VW engine needs.

I use 5w-40 Castrol Syntec without any issues.

Edge worked great for me. Maybe the best oil on the market.

Just put mine in today at the owners manuals advice, 15,000 KM. Castrol 5w40

I prefer to use castrol gtx 20w-50 year round, but I'm being cheap lately. I've put over 120k on my 16v with this stuff so far

Dealer put Castrol SLX Professional LL03 5W30 in it.

I run 5w40 syntec and I eat about 1/2-3/4 oil every 5,000 miles. It will eat it more if I drive it really hard.

Mine eats Castrol Syntec 5w40 like it's going out of style as well.
