    Oil change

    Hi All,

    I'm contemplating an oil change, not due for another 9k miles but i'd like the reassurance that it's been done properly.

    The recommendation is:

    Castrol edge C1 5w40

    Is this what everyone is using, it seems a bit like rocking horse poo, and very expensive?

    Is the premium for C1 oil over long life oil worth it?

    Also, any recommendations for the oil filter brand?

    Phil

    Sorry, got that wrong, the recommendation is:

    C1 5w30 (not 40)

    The filter is just as important as the brand of oil, remembering that the most expensive option isn't necessarily the best when chosing either oil or filters. Wink

    I use Wix or Mahle oil filters in mine...reputable and quality filters that I've used for years both professionally and in my own cars...but a quality filter of any decent brand is fine.

    Just a few tried and trusted favourites...

    Air filter: Pipercross or K&N for performance washables. Blue Print, Wix or Mahle for OE style paper element.

    Oil Filter: Wix or Mahle

    Fuel Filter: Mahle, Cooper (Fram) or Bosch

    Oil: (for me personally): Castrol Edge C1 5W30, although there are far cheaper alternatives (such as Millers C1 5W30) which are just as good if you're replacing the oil & filter regularly below the 10k miles recommended service intervals..

    Harry's suggestion of looking through the Opie Oils website is a top tip. It's a one stop shop for most service parts and fluids from brakes to windscreen wipers. Thumbs Up

    I change my oil and filter every 5k-6k miles, fuel filter every 10k miles...which is more of a habit than strictly necessary, particularly with modern longer life fully synthetic oils. 10k miles is still a bit too long between service intervals on older, higher mileage engines for my peace of mind though. My Pipercross air filter and K&N cabin pollen filter are washable so don't ever need replacing...just cleaning once a year.

    Since I bought the Bling Barge exactly a year to the day ago, I've replaced both timing belts plus tensioners and both camshaft pulleys, the water pump and the auxiliary belt, flushed and replaced the coolant, flushed and cleaned the DPF unit, serviced the gearbox, transfer box and diffs as well as regassing the HVAC system (not really needed but done anyway). I power bled the old brake fluid out when I replaced all the pads and serviced the brakes yesterday. Replaced a brake pad wear sensor on the NS front wheel...didn't show any DTC's on the IID tool, but the sensor end looked a bit dodgy.

    Apart from the two window regulators that broke and had to be replaced...reliability wise, the Bling Barge has been very well behaved. (Touches wood, spins 3 times) Laughing

    I'm kinda like minded in that if I've done the maintenance and servicing myself...besides giving that extra peace of mind, at least I know it's been done to my own rather fussy standards and not just ticked off on a service schedule. I'd much rather be proactive with preventive maintenance than being belatedly reactive when it's done the Land Rover thing and randomly exploded into a pile of bits. Neutral

    The Bling Barge is 8 and a bit years old, 79k miles and I'm it's 3rd (and probably last) owner...but it's getting to be just the way I like it.

    As an aside...If you haven't already got one of these 7L hand operated vacuum pumps for your oil changes... saves crawling around underneath the car taking the sump plug off and covering yourself in slightly warm engine oil. Highly recommended for anyone doing DIY servicing at around 30 quid from Amazon or eBay. Mr. Green
