    Do your part for Mother Earth, cut back on children.. or at least stop eating meat. I'm heading down to McDs for a sausage muffin before they run out..

    Kewl. Is it a commercially available kit or a roll-your-own? Are you getting a compressor for home filling or using a local station?

    Commercial parts. Mostly DIY install (I think, we'll see how it goes).

    No plans for a home compressor yet. I have stations on my usual routes.

    Now you can stop hypermiling since your fuel will be equivalent to $1 a gallon :)

    Deflate those tires to 22psi for comfort.. you actually believe anything from that livestrong website?

    Volvo Trucks and Shell Agreement to Widen Use of LNG in Transport Sector

    Volvo Trucks and Shell have agreed to cooperate globally on the introduction of Liquefied Natural Gas (LNG) as a fuel for commercial heavy duty trucks. Based on Volvo’s new MethaneDiesel concept whereby LNG can be used in diesel engines, and Shell’s LNG expertise and infrastructure investments, the two companies will coordinate their activities and actively support the wider use of LNG in the transport sector.

    I'm waiting on some software and Ford service manuals/wiring diagrams. ... I've got a few kinks to work/ tune out. It's going to be a little while before I can get some good cng performance comparisons.

    Ok. I've got the software and wiring diagrams and have played around a little with the tuning. Still have a long way to go.

    Preliminary data indicates very little if any drop in highway mpg. Traveling at 70 mph with a 10 mph headwind and no tonneau cover the pickup (f150 4.63v) averaged 21 mpg** over 133 miles on cng.

    "Seat of pants" does detect a 10% or so loss in power. The pickup can't hold 6th gear as long on uphill sections of the interstate, it seems to take more throttle/higher rpm/lower gear for equivalent pass vs gasoline. Noticeable, but not a problem.



    /** actual miles/gge computed to 23 mpg. I suspect I was about .6 gge short on the fill due to variance in cng fill.

    I ran another cng tank through to empty on the highway today --- this time at almost 24 mpge (162 miles on 6.8gge). Both of these highway tanks are indicating an increase in mpg (vs e0 gasoline) of more than 10%.

    Quite surprising as I was expecting cng to drop mpg a little.


    /I should mention that the software can be set to switch to gasoline or bring in a mix of methane and gasoline for high power situations. I'm told you can also do a custom tune for economy but I haven't gotten that sophisticated yet. I'm running the basic "auto tune" with some tweaks at idle/power off coasting.
