Quick Oil Question
 

Hi all

Just a quick question:

My MY06 Spec D is coming up for service, so I called the garage to check which oil they use, the answer was 10W-40 Semi Synthetic. I've check the manual, and that's fine, but page 11-20 says that 5W-30 is recommended.


The shell "Lubematch" suggests HELIX F 5W-30, but I'd rather go for fully synthetic.

The top-up that came with the car is Shell Helxi, (5W-30 IIRC).

What Shell Helix do you guys use?
