No. The W is just a model designator to differentiate between AeroShell ashless dispersant oils (Oil W) and straight mineral AeroShell oils which have no letter designator.

No. The pilot or mechanic should always review the manual for proper procedures. For example, on most engines an inspection of the oil pan's suction screen is recommended at each oil change. Although one may rarely find anything during a maintenance check, it's not worth taking the risk.

No, D A M does not have any ammonia or other strong chemicals that could attack or shorten the life of any plastic. D A M has a very small amount of alcohol (less than .3%) in a water based solution. The quantity is so small that it has no effect on plastic or other surfaces. D A M is safe on all surfaces.

Per the manufacturer, Plane Power alternators do not include capacitors.

Yes, the hole for the grouding strap is drilled and tapped, ready for strap installation as necessary. 

No. Due to the additive technology in ashless dispersant lubricants like AeroShell W Oils, the flow characteristics of each grade are roughly equivalent to the next higher grade straight mineral oil. For example, AeroShell Oil W 100 will flow at low temperatures about the same as AeroShell 80.

Yes. AeroShell straight mineral oils meet the SAE J-1966 former MIL-L-6082 specification.  AeroShell Oil W single grade and antiwear, anticorrosion AeroShell Oil W 15W-50 meet the SAE J-1899 former MIL-L-22851 specification. The AeroShell containers are labelled with both the new SAE specifications and the “former” military specifications.

Yes, all Tempest aviation oil filters use a magnet. This give us an extra layer of defense to help filter out smaller micron particles that may get past the filtration media.

No, they will only include the bushing. All mounting hardware will need to be purchased seperately.

The oils are similar, but there are some differences. The biggest difference is in cold flow characteristics. AeroShell Oil W 100 is up to 10 times thicker at cold temperatures than AeroShell Oil W 15W-50.  However, at normal operating temperatures (around 200°F), both oils will have the same thickness or viscosity.  Another major difference is that AeroShell Oil W 15W-50 and AeroShell Oil W 100 Plus have an antiwear additive which is not in AeroShell Oil W 100. This additive, along with the semisynthetic base oils, helps reduce friction and improve flow in AeroShell Oil W 15W-50. 

These additives improve lubrication and reduce oil consumption past the oil rings. Conversely, the improved flow can increase oil loss through leaks or loose intake valve guides.  So your oil consumption may go up or down if you switch from AeroShell Oil W 100 to AeroShell Oil W 15W-50. The improved flow and reduced friction characteristics of AeroShell® Oil W 15W-50 will also help reduce oil temperatures as opposed to using AeroShell Oil W 100. 

This is particularly important in engines that run hot, like turbocharged, high performance or aerobatic aircraft engines. Pilots should always remember to monitor oil temps to ensure that they’re not too hot. 

In cold weather, you should also make sure that the engine temperature is high enough to boil off the water that naturally accumulates in the crankcase. Temperatures in the 180° to 200°F range are recommended for most applications. Finally, if you have a marginal or slipping starter clutch, the antiwear additive in AeroShell Oil W 15W-50 may cause it to slip more than AeroShell Oil W 100.  Understanding these differences can help you select the grade of AeroShell that's right for your plane.

Yes, lithium battery can be installed in any position for they are a dry cell technology.

Yes! All of the PowerUp Slick Aftermarket parts have been FAA-approved to be equivalent to or improved than Champion Slick parts. PowerUp’s Aftermarket Slick parts have been in production for 30 years and tens of thousands of our parts have been put into service.

All AeroShell oils are compatible and can be mixed with each other. Many single grade customers try AeroShell Oil W 15W-50 during the colder part of the year, then convert to using it year round. Others, however, choose to alternate between single grade and multigrade depending on the time of year. Either system works well because AeroShell oils are entirely compatible and can be interchanged as desired. 

In addition, if you need to replace a cylinder on a mid-time engine, you can switch from AeroShell Oil W single grade or AeroShell Oil W 15W-50 to a straight AeroShell mineral oil for one or two changes to break in the new cylinder. Then you can switch back to the ashless dispersant oil after the rings are properly seated. 

If you have a mid-time engine that has been run exclusively on a straight mineral oil and wish to try an ashless dispersant oil, use caution. The introduction of an ashless dispersant oil into your engine could loosen up some of the carbon deposits. So check your oil screens and filters often to ensure against oil starvation and/or oil screen collapse.

No, the voltages are not the same and you will over charge the lead acid battery and drain the lithium.

Since inception in 2009, EarthX has designed their lithium batteries with a micro-processor-controlled battery management system (BMS) to provide safety and performance features for your battery.  EarthX is not new to providing lithium iron phosphate batteries. Over the past 13 years, has become the most trusted and used lithium battery in the experimental aircraft market and by working closely with OEM’s and engine manufacturers a like, this BMS has been developed to be one of the most reliable in the industry. EarthX is not only the exclusive provider for the Indy Race Cars, but EarthX is also the first company in the world and in history to have an FAA TSO certified aircraft battery as a testament to the safety and quality of the batteries.  

Features of the BMS protection:

• Cell balancing
• Low voltage protection
• High voltage protection
• Excessive Cranking Protection (Heat)
• Short circuit protection
• In the Hundred series, an alert LED fault light to communicate an issue on battery itself or can be remotely monitored with a 12V LED
• In the Hundred series, the BMS board is redundant so there is no single point failure

Battery design safety features:

• Proprietary battery case design with recessed terminals to protect from short circuiting
• Clam shell design with terminals down the center so polarity (installation) is never an issue
• Flame retardant plastic housing
• The state of the art ceramic cell separators to reduce the risk of thermal runaway by 400% over standard lithium cell separators.

Performance design features:

• The widest operating temperature range available
• A rated cells that must meet stringent testing requirements
• True industry standards testing specifications

They are sold in pairs and are one position per price. 

The compatibility question covers two issues: mixing one grade of AeroShell oil with another; and the effects on the engine of changing from one AeroShell grade to the other. If you typically run on AeroShell multigrade, and you find yourself in a place where only AeroShell single grades are available, you can safely add the AeroShell single grade to your engine. They are completely compatible. 

If you run on an AeroShell single grade during the summer, but want to switch over to AeroShell Oil W 15W-50 Multigrade for the winter, you can safely replace the straight weight with the multigrade at your regular drain interval. The idea that you have to stick with the type of oil you started with comes from the days of unusual chemistry when the resulting oils were incompatible. 

All approved SAE J-1899 (former MIL-L-22851) and SAE J-1966 (former MIL-L-6082) AeroShell oils are compatible. For example, if you have a high-time engine run on ashless dispersant oils and need to replace a cylinder, you can switch to a mineral oil for 50 hours or so to break in the new cylinder. The only time Shell recommends against switching is in a high-time engine run exclusively on straight mineral oil. Here, a switch to ashless dispersant oil can loosen deposits left behind by the mineral oil.

This is normal for a permanent-magnet starter. Although power is removed by releasing the key/start button, a permanent-magnet motor will actually provide power to itself as it winds down and will keep the starter drive engaged for about a half-second until it loses sufficient RPM to fully disengage.
