Mk2.5 1.8 VVT

Postby drumtochty » Mon Mar 06, 2017 5:22 pm

Just changed the oil on a 1.8 Mk2.5 and without thinking about it used Castrol GTX 10W/40.

Not an issue lubrication wise but most recommendations are for 5W/30 to run the VVT kit in the head.

I do not think it will be an issue but has anyone had a problem with the VVT kit with 10W/40 GTX.

5w-30 isn't recommended for Mk2.5 VVT engine, only Mk3+. 5w-30 is a low resistance oil and needs an engine designed for it.
The VVT engine is recommended to have a full synthetic 10w-40 to 0w-40. I always use Mobil 1 0w-40.
I don't think the oil you have used will be a problem at all though, just not quite perfect so might not last as long.
