    Saw this at Asda and was told it was nationwide, seems like a great price for a excellent oil for the petrols.

    There's nothing wrong with this oil, but I prefer by far a 0W20 grade for my Honda petrols.

    Same here the 8th Generation is a different beast with Honda 0w-20. Castrol well I don't consider them as a lubricant company but a very clever and effective marketer of lubricants,Other than that the oil if the right grade.

    Hmm any particular reason or anything to report?
    Thinking of doing this myself but still have plenty Race pro 5w 40 left.
    I might try it soon.
    Without opening can of worms but would I be better of with 0w 20?

    Zoran the move to 0w-20 has transformed the car ,better throttle response better acceleration better fuel efficiency and no oil consumption. So for all the doubter this is oil is rubbish and a thicker oil give better protection... they are misguided and deluded and are hanging to the past as change is a difficult thing to give up . lately on AOC the hasnt been which oil drumming banging here thank god for small mercies. :Happy:

    The 0w -20 has been debated in detail here with research from Honda ,so the doubters need come up its concrete evidence rather than hear say.

    Zoran I would try it and see what you think it better than to take the plunge rather than sit on the fence :Wink:

    Changed my oil few weeks ago but will give it a go when i come back from my annual Euro trip in August.
    As long as it protect the engine but thinking about it it might be good for my car because i do lot of short stop start driving and only goes on motorway once in a blue moon.
    Will try it anyway and see how it goes.

    Just wondering if it's just me but does anyone else check the dates on the oil before buying? Just in case the ASDA stuff is old stock, I'm sure I read up that even unused oil degrades so you should try and get stuff as new as possible. I've seen stuff in Halfords that is several years old!

    The only issue with older stock is that there might be the possibility the product does not match the latest standards/specifications. This can only be a problem if you have a brand new car that requires a very recent specification.
    Where did you find that unopened cans degrade? There's no oxygen, temperature fluctuations, acids, fuel, soot, etc... that can have any impact on the oil.

    I can't remember but I did a wee search and came up with a link from Mobile. I think the main thing is as you said, the specifications becoming obsolete, then it's temperature differences but there's also mention of separation - although would the engine not just mix it all back up?

    Here's the links, I think it could just be a belt and braces thing as Valvoline don't say there's shelf life. But for me I just look for the newest date as it only takes a few extra seconds to do and feels better! lol

    drr oil threads when you thought you saw the last of them them come back to haunt you like a bad rash it :telloff: we already have enough oil topic to drown whole of Saudi Arabia in it !!
    I recall opie oil mentioning the oil doesn't have a shelf as such but they can last for five years if they are sealed and unopened , but the additives within the oil don't last that long. So for H&S aspects they will say 1-2 years to cover themselves for wannabe suing specialists
