  1. Car : 2009 Legacy BR Wagon, 2.5L NA

    Tuned or stock?: Stock

    Fuel : 95 from wherever's cheapest.. normally Mobil

    Fuel economy : Open road driving: 7.5L / 100km (13km / L) City: 9 - 9.5L / 100km (10.5 - 11km / L)

    Fuelly stats if known :  Haven't been using Fuelly, but maybe I should

     

    My economy stats are based on before I installed my roof racks & cycle carriers. Road trip from Auck - Welly consumed 44.41L for 630km = 7.04L / 100km. My next trip was with the racks installed and a bike on the roof - 24.95L for 279km = 8.94L / 100km... quite a difference!

     

    I'm going to test this out again on my next couple of road trips - to Tauranga with 2 bikes on the roof... then again to Rotorua with everything taken off, and see how they compare.

     

    EDIT: The other thing I neglected to mention, was that I've also changed my wheels and tyre size from when I got it. It did have 17" rims, now it has 19" rims with a higher circumference tyre, so that will also be affecting the gas mileage.

    which that situation is covered by your insurance too

     

    Say you've damaged / lost your first key and claim getting a replacement under insurance, and just pay the excess?

     

    Caveat: It may increase your premiums for next year if you lose your no claims bonus.

    Depends on what your after. So many different materials and companies that make them.
    Could DIY a pair from Supercheap or something? Be a bit different and fully custom?
    The OEM ones are quite nice too: https://subaruonlineparts.com/subaru-legacy-splash-guards-p-1821.html
    Or ebay specials: https://www.ebay.com/itm/4x-Front-Rear-Splash-Guard-Mud-Flaps-for-Subaru-Legacy-2010-2011-2012-2013-Sedan-/182449520214?fits=Make%3ASubaru|Model%3ALegacy

     

    None of them look like what you've done though.. yours looks like a cut out of a thick rubber, so you can get them wider?

  4. So I'm more or less just thinking out loud here, trying to figure out if my thinking and calculations are correct. Someone else may have already thought about this as well.. who knows.

     

    Driving my car, when the Speedo reads 100, my phones GPS actually gives me 93kph. The current wheels & tyres are different to the factory options, and when I use this calculator: http://www.tyresizecalculator.com/tyre-wheel-calculators/speedo-error-calculator

     

    And I enter the factory wheel / tyre specs vs what's on the car now, it says it now reads 99 when it should be 100 so the current difference is negligible. So for all intents and purposes, I'm using 100kph and it would still be underreading by 6kph instead of 7.

     

    So, I want to try and figure out what tyres I should use on my new car, to try and fix the speedo difference and get a more accurate reading. When I'm using the above calculator, there is this sentence: "Speedometer reads xxx, but the actual speed is xxx"

     

    So, when I'm wanting to compare different size tyres from the original to new, I should ACTUALLY put 93 into the "Speedo reading" box, rather than 100. Correct? Then it will give me a comparison reading based on the GPS'd 93kph / Speedo 100kph.

     

    An example:

     

    If current tyres 215/50/17 gives me a reading of 93kph, then comparing that to a 245/40/19 gives me a new reading of 98kph.

     

    So if my current speedo at 100 gives me a GPS speed of 93, by changing to the above new tyre it would then give me a GPS speed of 98.

     

    Or changing to a 245/45/19 gives me a new reading of 101kph.

     

    Does that stack up? Comments?
