Holden Rodeo V6

Thanks Will - not really the response I was hoping for! If that is the best that I can get then I think the old Rodeo will be getting the arse pretty quickly. That sort of fuel consumption is crazy - especially when comparitive vehicles (Triton and Hilux) get considerable better - around 7-8km/l. Know anyone wants a good Rodeo....

g''day keith you haven't mentioned if your rodeo just started chewing juice or is it always that bad. a mate of mine's went from good to attrocious in just a week apparently after much head scratching it was diagnosed with a faulty oxygen sensor. just something else you might want to check, although they are expensive ,genuine there is an aftermarket substitute

cheers and good luck

Mine has always been pretty average but certainly appears to have got worse lately. Oxygen sensor a good tip and will investigate that. Thanks, Keith.

David - thanks for that. Could you please explain the ECM fuse thing a bit more. Not sure what you mean there. Have the finer filter on order already and hoping the see a difference there. Used to driving diesels so probably should rev it a bit harder too. Cheers, Keith.

Hi David,

Just a comment about your 5th point above. I've noted that at my local servo, 98 unleaded is always a flat 9c/litre dearer than normal unleaded. I've been keeping track of all my 'roos fuel consumption since April last year and noticed that when using 98, I do actually get 7% better fuel economy, roughly 1.7L/100km improvement. I don't get this improvement with 95 premium though.

What I didn't consider is that when the price of 98 is down, it is actually not worth buying it. For example yesterday I filled up with normal unleaded at 81.7c/L. The 98 was 90.7c/L. 98 is 11% dearer. Clearly that doesn't compare to a 7% consumption improvement.

However, as the price of ULP goes up as it did in the last couple of months to say 99.7c/L (or more), 98 was still 9c/L dearer at 108.7c/L. 98 is now only 9% dearer. Still doesn't match a 7% consumption improvement but it illustrates the point I'm making.

Assuming the difference between ULP and 98 stays at a constant 9c/L (or 5c/L, 7c/L, whatever), then it is actually more worthwhile to fill up with the higher octane fuel as the price gets dearer. Something to think about!

Nonetheless, I generally use normal ULP around town. But will always use either a 98 or Premium when on any sort of extended trip. The extra responsiveness is noticeable and makes the trip more pleasant for me as the driver. I start using the 98 two tankfuls ahead of the trip so by the time the trip rolls around, the octane rating is not diluted.

Cheers...Savvas

PS...Make that the 4th point, not 5th!

Thanks David - bit new to the web page idea and didn't click what you meant by thread (thinking bolts....). Hope it sorts her out a bit. Cheers, Keith.

Peter,

I just have to ask....how did your Rodeo fair after the dunking in the photo?

Yep - found the info on the ECM and will give it a try shortly. I am in Darwin and the economy figures I got were from a run to Kunanurra and back (1600km total). I was sitting on around 125km/hr going across and probably 110km/hr coming back. The car had no load going across and I was towing a 12ft tinnie back (but would be surprised if that made a great difference). I was following an auto commodore back and he was getting 9-10km/l under the same conditions. Still waiting on my finer filter - things up here only happen in NT time (Not Today, Not Tomorrow!). If I can drag my rig upto around 7km/l I will be more than happy. Cheers, Keith.

I must be in a fortunate position here as the 'premium' juice is 5c/litre up on the normal. So when normal is 78c, as it here most Tuesdays, then it less than 5% dearer to use the 'premium'. I'm fortunate I have a 115 litre tank, so I can put off buying fuel til the price is right.A bad days sailing sure beats a good day at work

I have a full cage on the back, with a tyre on the top. The cage follows the line of the cab pretty well, but the tyre sticks up a bit. Probably effects the fuel a bit, but not to level I experienced. Have fitted the finer filter which has helped slightly I believe, but have yet to get around to checking the oxygen sensor. KT.
