While we are on the subject, I was after some info. My uncle owns light plane and CASA has informed me that I can't add this to the engine due to a couple of things, 1. It's not an approved addative nor a patented product and the chemical composition is not up to aeronautical standards yada yada yada?!?!? and 2. It reduces metal integrity by imbedding it’s self into the metal which on constant revving engines can cause a decrease in thermal efficiency. Sounds a bit ‘how ya going’ to me, didn't really get a straight answer from them, but do you know if any of this is correct? Thanks :)

An internal combustion engine is a great big oversize heat pump... it relies on heat not escaping in order to be most effecient. I'm also aware that Roil isn't for use in the general aviation industry... having been a pilot for the last 4 years, and studied aircraft systems at Griffith University (I'll quote you my CASA ARN and Licence Number and that of my licencing delagate if anyone thinks I'm BSing!) And i don't beleive Roil afffects 'metal integrity' when the pinion drive that powered the 2000 Australian national drag Champion 'Sainty' that ussually has be be replaced after every second run, and even then comes out with hairline cracks, once a new pinion drive had been socked in Roil for 24hrs at last count I beleive has done its 26th run???

Note the rather large Roil sticker infront of the right wheel!

HoeTrain, the reason CASA wouldn’t recommend it is because they are a bunch of spineless, ball'les beurocrats who will not accept responsibility for anything. They wouldn’t even tell you the time without receiving written conformation from another source (just incase they were wrong). In all honest CASA know next to nothing about mechanicals (or aviation for that matter) and are just a lot of mindless beurocrats that hide under the comment "its in the interest of safety" (translation = "I don’t know and am not prepared to make a decision")

Sorry a bit of a rant, but when you have been involved in aviation (both flying and maintenance) a our family have, you have little respect for these pencil pushing dickless morons.

id like to see a proper test done by the manufacturers... like BMW and Mobil did with an old e30 with mobil 1 in it. they put it on rollers for 1million km's (might of been miles, i cant remember) and ran the engine non stop, and varied the speed periodically. they didnt change the oil at all and when theyd finished there was very little damage to the engine (similar to an engine thatd run 100,000ks using basic oil).

if a test like this was done (a before and after) there would be no variences like driving styles. and no one could argue that your full of shit (im not saying you are)

they wouldn't have to do a 1million km test of course.

    • That's not a transistor --- it's marked ZD1 which makes it a zener diode. As to what the breakdown voltage is, not enough there to divine.
    • Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers
    • The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.
    • It's almost certainly the same as the one next to it.

    • South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
