Certified petrolhead - long time Subaru owner, mostly high specced (PPP, STi or other performance mods) and will race anything with an engine.

Have been monkeying around with engines since the late eighties.

comment Diesel vs Petrol motorcars. Pro's and cons?
You may have some misunderstandings about petrol engines - I certainly don't change my plugs every service :-) Other than that I think you are broadly correct.

comment Does the amount of fuel in the tank matter?
As Brian's top answer says, it is on cornering that this becomes an issue.

comment What happens if petrol is used in a diesel engine?
What is gasoil? Petrol (UK) or Gasoline (US) is what you would run most car engines on, and comes in 95, 98, 99, 102 RON etc. Diesel is the main alternative (trucks, buses and a lot of cars). But you also have biofuels, biodiesel, vegetable oil etc. I think you really need to clarify what you mean.

comment Is there any particular difficulty in replacing Ignition coils in a BMW 528i?
380 for install, setup and testing by a BMW garage? Seems perfectly reasonable.

comment When cranking an engine between 15 second intervals is ok?
I agree with Larry, however I would also say don't let yourself be bullied. If you have stalled, take a deep breath, make sure you are safe, if the starter needs to cool just let it, and just try again.

comment How many amps should my car be pulling while it is turned off?
what did you use to measure current draw when the ignition was off? 0.78A seems incredibly high.

comment Why isn't it allowed to ride a new motorcycle too fast?
Larry - you say break in isn't required, and yet your comments and quoted article both say it is. I know it is only an extended break in for high performance engines, but a break in is still a good idea.

comment Keeping an old car alive?
Rust around wheel arches is one Subaru problem so keep an eye on these areas.

comment How can I connect an Aux input to a 2004 Honda Jazz stock stereo?
Actually I hadn't seen your link, but it looks like the same info so I'll delete mine off here. I just missed your final paragraph for some reason.

comment What bolt extractor will remove a broken motor mount bolt on a 2004 Subaru WRX?
That last sentence implies you found out the hard way - is it all sorted without injury now?

I love the terminal image:)

comment Why is the brake pedal higher than the accelerator pedal
I'm not certain this is correct, for example with my cars it doesn't matter how much has been worn from the pads - you still use the same amount of force on the pedal. There may be microscopic differences, but you can't notice them.

comment How much efficiency is robbed from 'pumping loss,' if any?
But why bother with WOT? The key point of WOT is you are forcing more fuel into the cylinders, so you'd be better off not doing that. Or am I misunderstanding you?

comment Does repeated turning on/off Xenon HID headlights harm them?
Definitely! My garage was astonished I managed to kill one- turns out I caused it by damaging a casing that allowed water in, which then froze at minus twenty! £600 for a new one :(

comment Will brake dust corrode my wheels?
Haha, actually my brakes are a pleasant gold colour, and I have removed as many pink badges from the car as I could.

comment Should I use coca cola or baking soda + water to clean my battery clamps?
Definitely use terminal cleaner - although if you are out in the middle of nowhere and can only find a can of coke then it can help remove gunk and corrosion in an emergency. Would be a weird kind of emergency though :-)

comment Will brake dust corrode my wheels?
I use a similar product, and add an extra step at the end - another application and then a scrub using a soft brush, followed by a final rinse. It just gets some of the hard to clean bits done. I also spray it on the brake covers to bring the STi colours back out form under their black coating of dust :-)

comment Does repeated turning on/off Xenon HID headlights harm them?
They shouldn't ever need to be replaced - in the lifespan of the car. That is one of the key benefits of HIDs - they don't get that thermal shock wear that ordinary bulbs get.

comment How are digital speedometer readings typically calculated?
The tyre pressure does impair the readings, which is one of the reasons all speedos over estimate the speed: legally it is easier for them to say as long as the speedo is at or below the limit your actual should Bree below there limit. The actual variance will depend on the headroom the manufacturer built in.

comment Synthetic Oil and oil change frequency
To be fair, though, If he flushes and uses synthetic on next oil change, 5000 miles will still just produce 5000 miles worth of contaminants. I'd be pretty happy with that, as long as the 5000 miles doesn't end up taking years :-)
