Those champion plugs look much like I'd expect a standard set to after quite a few k's - rounding of the centre electrode due to erosion, which also increases the gap. There seems to be bit of variation in combustion between cylinders but that might be due to the increasing gap....also could just be the photo. In any event, the amount of k's to produce the same erosion in a set of platinum plugs should be considerably greater (assuming normal combustion).

One possible common thing here is fuel - what do you run in these cars over there ??

Hi ...

Mostly 95 octane ... pump fuel.

Then there is 100 octane ultimate, but it's quite pricey.

I have not tried 100 octane yet, but will check it out once my gas tank is nearly empty.

I now have installed these NGK copper plugs (shame on me) and I have a slight misfire at idle (at least I think it's misfire)

And I'm under the impression that the car ran better with the AutoLite Platinum plugs. (though I have not fully tested)

Cheers from rainy London :)

Were they the .8mm pregapped ones ?? I had misfire at idle too with .8mm. Regapped them to 1mm and no more misfire at any rpm... If you can't be bothered regapping, might be easier/cheaper just to buy a new set (what is it like 10 euro for 6?) of the ones that come with 1.1mm gap and try those, I suspect they'll work just fine if the old ones were 1.5mm.

95 is probably a bit on the low side, but should be OK as long as you don't push it too hard and are running stock boost and timing. AFAIA these cars are designed to run on around 100 octane Jap fuel so the further you are away from that standard the more likely damage is to occur. Anyway, may not be the total answer for the plug damage you have, but possibly a contributing factor.

Yep ... they are designed for 100, but the knock sensor helps keeping low octane usable.

What fuel do you driver over there?

And how expensive is gas in Oz?

Cheers ..

GDay Andrew!

We use 98 RON fuel here and it's cheaper than yours! In Sydney, it can be $1.29/l midweek and then go up 10c later in the week.

I'd try re-gapping the plugs as Delta-F said with your 100 octane and get back to us.

If the Kms travelled is suss, had you thought of changing your timing belt?

Cheers, T

Hi Terry,

That's dirt cheap for 98 RON!

I'll come over to Oz then ... seems a good place for me anyway since I also have a dirtbike which I really would like to use...

As for the timing belt I have given it some thought already ..

I'd like having a look at the belt just to be sure ..

Is the cover easy to detach so the belt is exposed for checking?

As for the car:

The mileage seems suspiciously low but all the engine (serpentine) belts look like brand new.

Then there are the tires.

The manufacturing date for the tires seems to be 01/2001 and they're some expensive Japanese ones (forgot the name)

However the thread is at 85% ..

But one thing is for sure, it has been garaged since the paint is in good nick.

Cheers! :blush:

If the car is running fine and your happy with it, then I'd just drive and enjoy. The issue with the plugs will probably remain a mystery.

In terms of fuel, you should run as close to what is recommended as possible. 98 is the minimum I would run, but lower is possible, just take it easy. One thing - don't rely on the knock sensor to do your tuning for you (so to speak)....it's not designed for that.

Yes Andrew, I believe your petrol costs are about 33% above ours for the same grade.

I suspect that the North Sea Oil has been milk by the Norwegians whilst the English are asleep! :down:

That's why they won't join the EU!

And that's my version of a Conspiracy Theory anyway.

Look some of us up when in Oz eh?

Happy to know your car's in good nick. :ermm:

Yes Andrew, I believe your petrol costs are about 33% above ours for the same grade.

Actually, I think it's even pricier than that. It's over a pound there at present, I think, for regular. Which is about AU$1.90 at the current exchange rate.

Well ... I see what I can do.

Right now I'm glad I got the bonnet closed :)

But I guess I need to regap the plugs to 1-1.1 ..

:P

Right ... and given the current rate of exchange it is more like AU$2.20 for 100 octane ..

:P

To us Sydney-fellah-talk, that means we can pay for the fuel from Sydney to the base of Macquarie Pass and then go UP & DOWN Macquarie Pass for nicks!!! So that's what we save in our fuel costs to yours lolz

    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
    • We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
    • This is mine, works a treat for the cars, suction is good, I use the Bissell clean and protect stuff I have found giving it a good spray and light scrub with the soft brush on the head of the nossle for carpet, and a rub with a microfibre for cloth seats and cloth door trims, prior to another quick spray before vacuuming it up works the best @GTSBoy You would surprised on what it gets out of carpet and seats that actually "look" clean, I recommend that you test drive yours when you have a little time to kill, then post pics of the muddy looking water that I believe you will find
    • I think even the "commercial" capacity ones that you would hire from supermarkets etc wouldn't have the capacity to do all that much in one go. I will go through half a dozen tanks of solution and dumps/rinses of the waste tank for one little 2 seat sofa. Or similar for one 6 footish rug. That's the price you pay for something small that only takes up a bit of cupboard space, instead of something that takes up the entire laundry cupboard or half the shed.
