\"\"<\/a>Released by Rotax\u00ae today, is a revision of their Selection of Suitable Operating Fluids Service Instruction.
\nComing fresh from the RFSC\/iSC booth at AirVenture 2011, this SI answers probably one of the most frequently asked question of the airshow.\u00a0 What fluids should I use in my Rotax\u00ae aircraft engine?\u00a0 Is there a right oil?\u00a0 What about if I am using 100LL? If these items are on your mind then this article is for you.\u00a0 First, you can download this SI, just by clicking on it’s picture in the top left.\u00a0 Give it a good read.<\/p>\n

Let\u2019s have a look at some of the key ideas:
\nThe basic idea behind this SI revision was to add more information regarding the selection of suitable fluids for your 912 or 912 Rotax Aircraft Engine.
\nPlease make sure you are using this information with the latest versions of SB-912-043 or SB-914-029, as there is a change of coolant specification.
\nThe first section deals with the “what is the best type of fuel for my engine?”.\u00a0 If possible, use an unleaded or low lead content fuel.\u00a0 Note that the term low lead here does not refer to 100LL.\u00a0 It must be remembered that these engines were designed for auto fuels or mogas.\u00a0 I can hear the questions now:\u00a0 But what about the ethanol in the auto fuel?\u00a0 Can the engine handle that?\u00a0 Why, yes it can!\u00a0 If we look at section 5, we will see that up to 10% ethanol has been approved for use.\u00a0 However, in Section 5.1.2, there is a caution.\u00a0 Basically you need to make sure that the airframe components (things like fuel line, fuel filters and even some tanks) can handle the ethanol content.\u00a0 It is best to check with your aircraft manufacturer.\u00a0 ”
\nThe SI also deals with those owners that have to use 100LL. Yes, although these engines were designed with unleaded gas in mind, 100LL can be used, with some special considerations.\u00a0 It is important to understand that lead from the 100LL can build up in engine parts, so using the correct oil (see section 3.3) and changing the at the recommend interval of 25 hours (see section 3.3), is the way to go.
\nWhile on the subject of 100LL and lead, the SI talks about additives that aid in the scavenging of lead deposits.\u00a0 Product s like Decalin and Alcor TCP are mentioned.\u00a0 It seems that these are the only two brands that they have had experience with and say that they are not detrimental to the engine when used within the manufacturer\u2019s guidelines.\u00a0 They don\u2019t really come out and say they improve the situation or increase the recommended oil change intervals.<\/p>\n","protected":false},"excerpt":{"rendered":"
