    Best Engine Oil for a morning-driven 1.7 DTi (Y17DT) ?

    ..in terms of best for the maintenance of the engine, performance, protection etc.

    Unfortunately I have to often drive my car on short trips in the morning. I know this puts greater wear on the engine, so I am looking to mitigate this by selecting an appropriate engine oil.

    Also, would an engine flush (something like Redex engine flush at £3.99) be a good idea once a year?

    Any help/advice would be most appreciated. Thanks.

    I use vauxhall 10/40 semi in my 04 plate dti, I wouldn't bother with an engine flush as sometimes is does more harm than good.

    Do you think the Vauxhall oil would be better than one of those heavily-advertised brands such as Castrol?

    How can the engine flush cause harm?

    Thanks.

    It can dislodge the crap in the oil ways etc & block things up, I'd do a search & drawer your own conclusions, the vauxhall oil is just as good as castrol & cheaper.

    I had to renovate an old Vauxhall Engine and the big ends where wrecked through crap floating around in the oil. I Use engine flush all the time! engine oil stays a lot cleaner for a lot longer afterwards!

    anyone who uses a flush all the time is just asking for trouble

    i would only use one every couple of years max

    Vxl 10w40 will be more than adequate - even more so if u join AOC as a paid member then u can buy 5LTRS of the stuff for less than a tenner!

    Castrol is far from good oil but this like everything else is just MY opinion

    if ur concerned about shorter trips u could always try a 5w40 grade or similar this means its a little thinner at cold than the 10w grade. could be of some use in ur case...... alternatively stick with 10w40

    I would value your opinion as I am looking for many views on this.
    I don’t really know the differences between the many oils available on the market and I am therefore prone to believe whatever the ad-men claim.
    For example, Castrol Magnatec (I think that’s it) is famously advertised as having special additives within it that help protect your engine, when started from cold, relatively faster than other oils.
    Also it’s pricey so must be good etc. is a common belief.

    Views of forumites are much appreciated…

    My cars done 120,000 miles now and the next oil change is due.

    At what point should the switch from semi-synthetic to synthetic oil be made?
    I'd like to understand the thinking behind it if poss..

    I rang my local dealer.
    He said the oil for my engine should be semi-synthetic 10w-40.
    And it can be used for the entire life of the engine. He had not heard of the 'changing oil grade at different engine age' theory.
    He also said that the thicker the oil the less noticeable the diesel engine clatter will be. That sounds good to me!


    Anyone know how often the oil filter should be changed on these engines?

    Oil flush was used on my Z16XE from new, almost every 20,000 oil change. Did my engine no harm what so ever as proved at the 156,000 mile engine strip down. It reduces the acid within the engine and reduces carbon build up internally. Said engine also used Vauxhall 10w/40 exclusively. Synthetic at the right grade is better at any mileage.

    Oil filter should be changed with the oil so there's your interval.

    Deisel clatter isn't caused by parts hitting, so not sure how oil can reduce it, but happy to be enlightened
