ive just given the car a wee check up before i do a 300 mile journey today, the oil is down on the dipstick to about 3/4s, im going to stop off at Halfords to give it a quick dose of oil. What grade should I use? I dont have the handbook on me so cant refer to that, is it 10W-40 semi-synth? Will it be ok to stick any brand in until the 6000 mile point comes up and I do a full change?
cheers
steve
