Hey guys. I just saw the michellin ad talking about their Tyres saving you on petrol. Not considering them for my skyline but just curious if anyone knows how much of a difference they make? I don't see there being any significant impact based solely on Tyres

sounds like another marketing scam to suck all the hybrid and small car owners

Yeh, super hard tyres with extreme pressure have less rolling resistance, so in theory will save a bit of fuel.

On that note, Mythbusters last night tested the theory of tailgating a truck to save fuel. We all knew it would work, but I was surprised that they achieved nearly 40% fuel saving by following at 10 feet (3m). When they dropped it to 2 feet the fuel consumption actually went up. They claim it was due to the constant modulation of throttle to maintain such a close distance, but I reckon it's because they were almost under the truck so the slipstream hadn't had a chance to properly mix, and they were still getting a lot of "clean" air from under the truck.

Anyway, it was their usual highly questionable testing methods, but made for entertaining viewing anyway (although nothing got blown up, so they must be getting soft in their old age)

yes ^^^^^

but if you follow a truck on say - a highway... your fuel consumption goes down but you gain

stone chips

cracked windscreen

poor visibilty cos can't see past the truck

dangerous

annoying driving behind a truck esp during acceleration

not really worth it to save a few dollars a week!!!!

this is what annoys me - people who can't afford to run a car - yet insist to own a car... why not get a pushbike? or even motorbike?

Der, no shit sherlock. They weren't actually advocating that you should tailgate trucks (in fact quite the opposite). They were testing a myth because it's what they do. You know - myth busters?

If people read my post and want to start tailgating trucks to save money then that's a good thing. It will help clean the gene pool.

derrrr you idiot my name's not ACTUALLY Sherlock it's Rowan!!!!

haha nah i knew that - i'm just saying there's no way you can actually save petrol - if you do it'll cost you in other things

ie

overinflate your tyres will give you great economy... but decreases braking power and makes your wife think you're a bit of a cunt

ROFL - thanks for the coffee all over my keyboard

True - people will try all sorts of stuff to save a few $, like people who drive 4 suburbs to a servo because their petrol is 0.5c cheaper than the servo down the road.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
