    Default Defender 90 - Petrol vs Diesel

    Hi there,

    I am busy looking for a defender 90 to purchase. I was initially looking at diesel (TD5) only 90's because of fuel consumption. However, I have found a couple 2.8i petrol 90's that look like good buys, and I am starting to warm up to the idea of a petrol 90!

    Apart from fuel consumption, are there any other major differences between the diesel and petrol models?

    I appreciate any advice

    - Matt

    What you save in fuel consumption you will spend on maintenance. Td5 is a maintenance sensitive engine. You need to look after it properly.

    The 2.8 90 is probably one of the favourite Landys. I'm looking at the option of replacing my 300 Tdi hard top wioth a 2.8 on the basis that I (sadly) spend most of my time on tar. Short distance city riving is not kind on any motor, and even less a T diesel

    IMO people sell he 2.8's because of feul consumption (5km/L) realistically, and it becomes expensive going anywhere!! The engine itself is bullet proof.

    TD5 = 10 km/l @ 1000 km = 100L @ 7.20 (CT) = R720
    2.8 = 5km/l @ 1000 km = 200L @ 7.50 (CT) = 1500

    Thants R780 per 1000 km, at 20k its 15600 diff per 20k Service.

    Just find yourself a well looked after TD5, and look after it. Petrol just doesn't make sense!!!

    Wow those maths!! Makes me think about 2.8

    5km/l is a bit unfair? That is V8 territory. The 2.8 gave one guy I knew about 6.9 when pushing 150km/h (I know he is mad) all the way to Botswana.

    Can an owner of a 2.8 give us a proper number on combined petrol usage please? And a Td5 Defender owner as well while we are at it?

    I've just acquired a 2.8i and over the first month I have averaged 6 km/l. That is mostly town driving and, being a new vehicle, I have been using my right foot a little much to see what that 2.8 can do. Now I have calmed down a little my last few km have averaged more like 7 km/l. Not too bad.


    For me it was a decision between a 2.8 or a Tdi (also 90) and I couldn't find a Tdi in good condition.
    So far I am very happy I got the 2.8, still need to see what it does off the beaten track though.

    So adapting Hoarse beast's numbers with Simon's number, lets make it 6.5

    TD5 = 10 km/l @ 1000 km = 100L @ 7.20 (CT) = R720
    2.8 = 6.5km/l @ 1000 km = 154L @ 7.50 (CT) = R1155

    Brings us to saving of R435 per 1000 km. That is 3/4 tank of petrol

    So over 20k km you will save R8700. I'm not sure about 2.8i service intervals, IIRC it is 20 000km. The Td5 is recommended at 15 000km, but the guys owning them suggest rather go for 10 000km.

    That is where my knowledge run out, but looks a bit closer doesnt it. Annyone shed more light? Hacing second toughts..

    I might have overstated the consumtion of the 2.8 a bit it seems. I've been told that 5km/l is about right?? Maybe thats off road? not sure. I have a 110 TD5 and I get 10km/L round town, driving like a diesel should be driven; low rpm etc.

    Lets do the math @ 7km/l (better at 6, but nevertheless)

    2.8 @ 7km/l @ 1000 km's = 143 L @ 7.5 p/l = R1073 - 720 = 353 per 1000

    20k km's service = 7060 diff is feul cost. thats still alot.

    TD5's service interval is 20K

    I do my own services and an oil change a filters cost me about R800, I also use the best Synthitic oil I can find 5w-40 (the low 5 rating is to get the oil flowing as soon as the vehicle is switched on at cold, this cuts wear big time esp on turbo).

    When you got a thirsty petrol, you always are thinking twice before going anywhere, beleive me I know, I had a thirsty 4x4 and could not wait to get rid of it (between landies)

    What is the mainenance costs of Td5 vs 2.8 then?

    People are vauge about this, easy to see why. Intervals, prices, type of spares, type of oil etc makes it a tricky number to peg. We need engine specific mainenance, since the drivetrain maintenance should be the same. I'll try and get an answer from Landyonline

    Thanks for the helpful replies!

    Judging from the Defender 90 registry post - http://www.4x4community.co.za/forum/...ad.php?t=26007 - It seems fair to say that the 2.8i D90's average around 6.5-7km/l (some people reporting as high as 8.5km/l with mods to help consumption).

    I think I could live with that sort of average consumption. Anything below 6 is falling towards the no go area for me. I don't do much town driving during the week as I work from home, just one trip to Joburg a week and then a little weekend driving. Will be doing a lot more long distance trips once I get the Landy tho!

    Like O.B. I would be interested in hearing the differences in maintenance costs between the diesel and petrol models. Anyone have an idea?

    Sorry, cannot help on the perol??!! But it is a 6 Cyl which makes a difference to the costing.

    Perhaps someone with a 2.8 can shead some light here??

    Hi. I went through the same study two years ago as I could get an immaculate 2.8i Def 90 for a good price. The people I spoke to convinced me that I can work on 6.5 km/l. At this kind of consumption you must add in the price for an extra fuel tank on the 90 as the 54 litres just wont do. That consumption would definetly go down to 5 km/l or even lower doing thick sand / offroad. Even with the extra tank (40 l) you will only have a 564 km range @ 6 km/l - so you can add the inconvenience / space for jerry cans on certain trips. Diesel is in any case available everywhere in Africa whilst petrol is not. That made the decission for me to stick with my tdi. Other negatives which were mentioned by some of the 2.8i owners (obviously not my own experience): not ideal offroad where you need backcompression braking; some of the non-bmw sor LR tandard spares like water pipes, etc is not always freely available. Some guys had transfer or gearbox problems due to the power of the engine (I suppose could be due to abuse rather than anything else). I personally like the egine for it's reputation and power but my decision was based on the fuel related issues as mention. So it depends on your pocket and intended use.

    My D90 2.8i get with mixed driving 6.7 km/l and on a trip to Namibia fully loaded (including roof rack & tent) travelling at 110 115 km/h and with some off-road work averaged 7.11 km/l. If you can keep the revs under 3,000 (top speed 90 km/h) then you can expect almost the same consumption as a TD5. Problem is all the power available!

    With the off-road caravan (loaded 1250kg) not exceeding 100 km/h I had an average consumption of 6.1 km/l. At a speed of 110 115 km/h with the caravan and using 3 rd gear up to 100 km/h going through mountain passes in the Southern Cape the consumption was 5.3 km/l (this was with some wind).

    There are fewer things that can go wrong with a petrol engine that needs replacing, like no turbo, injectors. The BMW engine is bulletproof and mine has done 283,000 km using no oil between services (every 10,000 km). The engine was never opened, the same for the gearbox and transfer box. Only things that needed replacing was the fuel pump, radiator recore and water pump.

    Costs (includes VAT) on my last service at a non Land Rover dealer (he is BMW trained):

    Air cleaner R215 (Donaldson)
    Oil filter R127
    Oil engine R200 (Shell Helix Synthetic)
    Fuel filter R171 (change every 20,000km)
    Labour R456 (checking of plugs, brakes, oil levels, grease prop shafts)

    Maybe, just maybe you should be looking at a Disco V8. Mine's giving 7/km and more packing space than a 90. Diesel IMHO catches up to you when pumps & injectors need doing.

    Hey All, Thanks again

    I'm leaning towards the 2.8i petrol model at the moment! Hopefully going to look at one tomorrow, and if she is in good nick, may just purchase! 8)

    Cobus: How has the TDI treated you? Any major repairs needed since you bought it? Also if you don't mind me asking, what year and how many km's does it have?

    I definitely want to do some trips to Moz, Nam and Bots! Luckily they will be planned way in advance, so I can save for the fuel (if I go for a petrol model). As you say tho, it could be a bit of a pain carrying the extra petrol in jerry cans during these trips, but would be something that I would have to deal with if I go that route.

    For 2.8i owners, do you have long range fuel tanks fitted? Does it increase fuel consumption due to the extra weight carried in the spare fuel tank?

    lrswb: Your consumption on your 2.8i is definitely something I could live with. Sounds like you have a beaut Service isn't badly priced either! I will have to find a decent private Landy workshop around PTA/Centurion.

    Botsun: Haha, I actually did consider a Disco, but my dream is a Landy 90. Thanks for your input tho!

    Really getting excited now, just cant get it and take it to Dullstroom for a weekend!

    The rear main tank carries 60 litres. The aux tank under the driver’s seat base of my D90 carries another 40 litres and with 2 jerry cans at 6 km/l you can reach a total distance of at least 800 km. It is also possible to fit an aux tank under the passenger’s seat base giving you 140 litres without jerry cans.

    Extra weight has no influence as the fuel consumption for the 110 and 90 2.8i is similar.

    Good luck with your search for a D90 2.8i – indeed a good choice

    There would be no other choice for me. Fuel consumption is not that great but look at the below thread and what a mate of mine is getting, not too bad.

    http://www.4x4community.co.za/forum/...ad.php?t=30708

    My tdi 90 avereged 8.5km/l over about 60 000km. Being a diesel I generally drove it more gentle. When driving hard, towing my boat etc. the consumption wasn't that great. What was of bigger concern is the stress placed on the diesel driving it hard and the repair bills that comes with it.

    With my 2.8i 110 i avereged 5.6km/l over 15 000km but i must admit it was driven a lot harder (including a trip towing my boat for the Trans Agulhas at about 130 - 140kph for 5 500km). With the 2.8 loaded if you start losing speed uphill you gear down to fourth and floor and it and before you know it you're doing 160 in fourth.

    That BMW engine is a real gem and I haven't heard of an unhappy 2.8i owner ever.
    Started with a SIII 2.25d
    then a 2 dr V8 Range rover
    then a 2.4 DC Hilux
    then a 90 tdi
    then a 110 2.8i

    Just came back from viewing/driving a '97 2.8i D90. Has 166k km's on the clock and in good running condition. Took my girlfriends dad with who knows a lot about Landies having owned a couple and he says its a decent car with no major problems!

    It was listed for sale at R85k and I offered R80k and he accepted!

    The owner bought it a year ago as a "toy" and didn't really drive it. It also has a long range fuel tank already fitted and drives really well.

    There are just the following things that concern me about the car and would really appreciate some input:

    1) No full service history
    2) The odometer says 6k since he had it replaced. He said it was replaced at 160k.
    3) Bonnet paint is a little faded (probably from being in the sun)

    Other than that, its in really good nick for a 1997 Landy. Should the 3 issues above be of major concern?
