Car journey.. 4 hr round trip on motorway the other day. My oil light starts flashing. Didn't think much of it at first but thought I'd better get it checked out at some services I happened to pass. There was a Co-Op shop with all the usual oils and car maintenance stuff outside. Me, scratching head, didn't have a clue. Popped in and asked person behind the counter which oil would be recommended for my type of car..explained make, age and model etc.. she listened then said.."sorry, I am not allowed to tell you, it's not part of policy, would be liable if anything went wrong..bla bla " FFS, comes to something if they can't help you out at a services ! Stropped out and tried to look on google..was none the wiser. Drove off, on way home found a little garage (mot/car service type place )off the beaten track, popped in and what do you know... sorted thanks to lovely helpful people ! The end. But am I a bit thick for not having a clue about oil ? (and it took me ages to find the leaver thing that opens the bonnet)
