Going by the comments on here, it sounds like the 2.4s give trouble, but the 1800s are OK.

To be honest, don't get a GDI. I'm a mechanic and I've been stuck fixing my 98 Legnum for the past week. A lot of smoke, and now the gas has oil in it for some reason.

Kia ora. Do the fuel tanks on a 1997 Legnum have a bung? If so, where is it located???

I have a Legnum ST GDI 1.8, just picked it up, runs well (fingers crossed), and won't cause me too many problems in future. Very tidy. It's very economical, I'm happy on this front.

Never put 91 octane in these cars, it will ruin them.

I had a company car, a Mitsubishi Carisma, back in 2001. Same engine, only 2 years old at the time, put 91 in it by mistake, hissed and missed non-stop for ages. I should have just sucked the 91 fuel out of it, instead of running it through with higher octane fuel and an octane fuel booster additive.

The higher the octane the better for these vehicles...

Sorry, what's "kia ora"?

I have just bought a Legnum GDI SW. What is the best fuel for it to run on please? It has 91 at the moment; do I have to run it to very low before I put different petrol in, or what do I do please? Which petrol should I use?

Cheers, NZ Girl.

Never, ever run a GDI on 91 fuel - always at the very least 95, but best for it is the 97. You'll end up with problems with 91 on those cars. Don't wait until the fuel is low.

Yes!! I have read through every forum. I have had all the same problems. I took off the throttle body and intake, cleaned out an ice cream container of carbon build up out of the intake, throttle body and intake ports, and it went great for maybe 10 km, but still had the same problem.

So after hundreds of dollars spent on throttle body cleaner, injector cleaner trying to clean nonexistent carbon left overs, I decide that even though all cylinders were firing (very inconsistently), that I would buy some new spark plugs, I put in the plugs today and now I feel so stupid for how much I spent on dead ends. I nearly bought coil packs, torque converter... If anyone has rough idle and horrible acceleration, I would definitely spend the 20$ for a set of plugs before even trying anything else, although removing carbon build up in the intake and throttle body is not a bad idea. I also found if I sprayed through throttle body cleaner, the car went great for a few km, which was why I didn't think it was spark, but I was wrong. Definitely spark plugs,

Hi there. I own a 98 Mitsubishi Legnum. Been running it on 91 petrol, but new spark plugs, and changed the gas to 98, but it won't start and the engine light is flashing on and off. Does anybody have an idea on what the problem maybe?? Thanks in advance...

Mate, I've had mine for 11 years now. They're the best car I could ever own; I love it. On the open road I will challenge any car, but when it comes to hills, she gets a bit shy, but best on gas.

97 Legum ST V6 - the best car out there.

Hi there everyone. I bought a 1997 Legnum ST in November last year. Just clocked over to 295000 the other day. I tried 95 when I bought it, then the next week I did 98. Haven't looked back. I get an extra 20 to 25 km out of it, and so smooth, but just wondering what is the best fluid for the auto gearbox?

13th Apr 2016, 20:22

From what I am aware, Mitsubishi (like Honda) uses a particular type of fluid; competent automatic transmission repair shops should know this, else the dealership parts department will have it available.

I own a 1998 Legnum GDI ST. An awesome car. It's my first car, runs like a dream. I try to run it more so on 95 as I've heard it's better for it. I just find it gets a bit tight. The 1.8 may not be very powerful, but is fairly economical. I've been using Tiptronic a bit; I feel that helps with fuel as well as you use lower revs, but an awesome car!

Run it on 98 when you can - that is the fuel it was designed for. 95 if you can't, but it will be even more efficient on 98, even if it's dearer.

I have a 1997 Mitsubishi Legnum 1.8 tiptronic. It has been going through a lot of water and overheating when driven for too long. I can't see the water coming out from anywhere when I'm putting it into the radiator, so no leaks that I'm aware of. It is also surging while driving (making a popping sound) and idling like it's running out of fuel. I don't know if this problem is related to the overheating problem or a whole different problem. Can anyone give me advice on where to start?

3rd Aug 2017, 08:00

If it's overheating and going through water, you may have a blown head gasket. Take it to a mechanic and have him do a pressure test on the cooling system.

Just brought a Legnum run around vehicle. Noisy though; sounds like it is coming from the cambelt area. Any ideas? Brilliant vehicle though.

Where is the bung on a 97 Legnum?
