I'm confused, how often should I get the oil & filter changed in my 1998 3.1 Trooper? At the moment i have it changed yearly. My mileage is only 52000 and average around 8000 a year. I've seen on this forum quotes of changing oil every 3000mls..........brilliant caravan towing vehicle it doesn't even know when it's being driven on the other side of the road in Europe

many thanks keith

Hello Keith.......
I religiously change my oil every 2500 miles and the oil and filter every 5000 and currently at 152000 miles its still as sweet as a nut.

Towed caravans in France & Spain and up in the Pyrennees into Andorra never a problem or a hiccup.

Jon.

it depends how long you want your engine/turbo to last ? oil & filter changes are cheaper & less hassle than engine changes ! manufacturers recommend longer service intervals as a selling point.

When the 3.1 ist came out the oil change interval was every 3000 miles,then it changed to 4500miles (because of customer complaints about servicing costs I expect) but when Vauxhall brought out the Monterey it was 9000 miles so that it fitted in with their current service schedules! I'd change the oil and filter every 3000 miles regardless especially if you use it for towing.

My manual says every 4500miles, which I follow, when I 1st got the car,I changed it every 6k, but I did recognise the tractor engine noise once it got over 5k.
So now, oil and filter change every 4,500, I also get semi-synthetic in 25lt drums, works out £1/litre.

Oil every 4500 miles oil filter and fuel filter every 9000 miles I dont recall the air filter intervals at the moment.

Thats what it says on the manual and service book of our 1998 3.1D as well.

Always do both filter and oil at 5000ks or 3000miles..
Pray tell what's the point of leaving a litre of FILTHY oil in a FILTER that looks like *beep*.. a filter is so cheap and a new donk so expensive..

Yep me too, change the oil and filter at 3K on my 2.8, but then a filter from Milners is something like £2.50, so I buy one of their full filter kits and a couple of extra oil filters for the intermediate changes between the full services.

Thanks a lot guys, and there was me beating up my reliable Troop all for the sake of regular oil changes. What do think of me changing the oil & filter twice a year and air filter once a year? Normaly when I have a service I would have the fuel filter changed at the same time just to be sure what do you think.

Unfortunately I'm getting too old to scrawl under cars these days so I have to ask a local mechanic to do it for me consequently It costs me loadsa £.

thanks again keith

[davedgreat]

If you want to risk kwikfit , they'll do oil and oil filter change for £18.90, thats just for mineral oil though. Most cars do at least 15k on a fuel filter change, I wouldn't be changing this filter twice a year, if your mileage is average, as you may start problems with air tight seals etc. Also do quick visual on the air filter, if it's *beep* up, change it. hope this helps.

Amazing amount of confusing information about this subject. I change my oil and filter every 5,000kms (3,000 miles) and my air filter once a year but do change it around in the housing at oil change time.

Here's what the Bighorn handbook says on a 3.1:

Oil - 3,000 miles
Air - 6,250 miles
Fuel - 25,000 miles
Man Trans oil - 25,000 miles
Auto Trans oil - never (!)
Front diff - 25,000 miles
Rear Diff - 25,000 miles

Looks like for engine oil they upped the mileage on later 3.1's but I'll stick with the original.

Recently changed the LSD oil in mine. What a mess! The gunk that came out defied description. Been quieter since so well worth doing and only a few quid.

Iv'e recently got me a 3.1td,and would appreciate any advice regarding the type of engine oil to use at service.Is the use of isuzu filters a must ??. thanks guys.

[Hard1]

Welcome to the forum! I use 10-40 semi-synth Motul but any good quality synth, semi, or plain mineral will get the job done as long as the oil and filter is changed regularly (every 3,000 miles). With a top grade fully synth you can stretch the service interval some, it's up to you.

I use Milners Off Road for all service items. They do great deals on service packs for 3.1 and deliver next day. No hassle.

You're possibly being a wee bit general in describing the suggested oils..always use diesol rated oil.. they have additives (detergents) to minimise emissions and absorb the nasties.
Your likely working ambient Temperature should also be a consideration..if you are likely to experience temps below freezing you should consider a 5-40 or 10-40 rated oil..if you own a later model 3L I believe you only ever use 5-40..
Enjoy your winter and those easy starts with a quality 5-40/10-40 rated oils.

Cheers
