Hi everyone, this is my fist post here. I have a question about oil for VW 2.0 gas engines.
Someone I know with a 2000 Golf 2.0 has been seeing some oil consumption (I would guess 1 - 1.5 qt in 5k miles) with the Citgo 10w-30 their mechanic puts in, and I am trying to help them figure out a solution.
Here's what I know: for my 2001 Passat 1.8T the owner's manual says to use 5w-40 or 5w-30. However, the service manual says that 5w-40 or 10w-40 are preferred, 15w-50 is ok, and that 5w-30 is ok for adding when low but NOT ok for oil changes. The 2.0 engine is not used in the Passat, but the service manual says this applies to most VW 4 and 6 cylinder gas engines. The dealers I have asked seem to use 5w-30 or 10w-30, in conflict with the service manual. (I use Mobil 1 0w-40 in my 1.8T, but looking for a less expensive option for my non-turbo friend).
So, it seems to me that 30wt might be too thin for this engine and a switch to 10w-40 is in order (this is in Baltimore so it gets cold but not too cold). Is this likely to solve the problem? Are there particular conventional 10w-40 oils that are better or worse than others (I know this is kind of a big spread for a conventional oil)?
Thanks for your advice!
