Hello,

At the moment I have Castrol Magnatec 10W40 in my 03WRX PPP,

UK car, used in the UK.

Is this OK, or should I change it for something thinner?

Thank you.

 

Read the oil post 7-8 posts below this.

Use GreaseMonkeys clicky, and get ready for a long read.

 

Magnatec is only semi synthetic so I made the decision to use fully synthetic in my 01 wrx and use Shell Helix Ultra (I'm lucky cos I use my own car on company business and get a fuel card so Shell stuff is handy to grab and pay for on my fuel card )

Good luck

Nick

Cheers Nick,

You would think after two years and 4000 post I would be able to do that........
