The car is fault free now so feel its worth giving her a service while im at it. Question is...
Does the 1.8 vvt sri respond better to a 0w30 oil or a 5w30 oil?
If anything I would like the engine to run smoother/quieter.
I'm between the opel/gm dexos2 5w-30 oil and Shell Helix Ultra Professional AG 5W-30. Which is the best? the car is an opel astra h estate 1.6 twinport 105 hp
Please suggest other dexos oils, if they are better :)
