The Auto Meter 9105 ecometer Fuel Consumption Gauge works great but when driving at night I started to experience a slightly distracting problem. A reflection of the guage’s display was very visible higher up the windshield. This was probably aggravated by the fact that I have it placed directly on my dash, which curves up and thus causes the guage to be at more of an angle than if it was sitting flat.
I’ve managed to reduce the amount that is reflected, and could eliminate it further with a small modification, by building an extension of the guage’s hood. I lucked out and was able to find some black vinyl just sitting around (I originally asked a friend if he had some black construction paper but he had something better – vinyl), which I affixed to the hood of the guage with electrical tape to extend it out. This little trick seems to have been a significant improvement when driving at night.
Updated 09/15/2011: I’ve reversed my opinion of the liners since I wrote this post. I began to have less effective rest after a few days. Last night I removed the liner and ended up sleeping well despite only having about five hours of rest. It’s still possible it was a fluke but in the end I’m not sure these really add much. I can’t say with certainty whether or not they improve or inhibit rest but for the cost and uncertainty I’m ruling that they just don’t make much of a difference for me. I still have 28 more liners left so I may try them again. If my opinion changes I will update this note.
Updated 10/25/2011: I’ve tried them a few more times since my last update and I still haven’t seen that they help me. However, my wife tried one (that wasn’t even fitted for her mask) one night and thought that it made a big difference with her medium ResMed Quattro FX mask). I’m going a different route. I’ve ordered a Pad-a-Cheek Mask Liner. I’ll add a new post after it arrives and I’ve had a chance to use it a few nights.
After recent spell of a few nights of bad sleep I started looking into anything that might help prevent mask leaks. Fortunately, I managed to make a few changes that let me sleep well without any new CPAP equipment. Yet, I had already ordered some mask liners after reading various product reviews and a few forum posts.
Last week I purchased a set of RemZzzs Padd Full Face CPAP Mask Liners from CPAP.com for $24.95 (before shipping). Note that you can purchase these from other suppliers but it’s important to ensure that they’ll fit the mask and mask size that you use. CPAP.com has a chart on the mask liner page that will match up different masks with the appropriate liner sizes. In my case, since I use a Resmed Quattro Full Face Mask (Large) the chart listed the “Large A” mask liners as my preferred size.
