(TRI). All training was in a 172. I'm now the proud owner of a '75 Tiger N74026 and have about 11 hours total in the Tiger and having an absolute blast. As a new pilot and plane owner, I have been doing LOTS of reading and learning and would first like to say how much I value and appreciate all the good information on this list. That being said, there are a few questions I have I'm hoping some of you kind folks can help me with. 1. Oil: My engine is a new Lycoming factory rebuild and I'm still breaking it in. Total time since rebuild is approximately 20 hours and the oil usage has stabilized and hasn't used any oil in the past 4 - 5 hours. I plan on changing the oil this weekend (going to regular oil rather than mineral oil). My question is regarding the oil filter. The current filter is CH 48110-1, however I've noted some people are using CH 48111 which looks to be about 2 inches longer. Are these two filters interchangeable with no problem? If so, I'd like to use the 48111 as I assume the bigger filter may do a better job of cleaning/cooling the oil. Is this correct or am I off base? 2. Auto-Gas: O.K, I know this is a touch subject. My understanding is there is an STC for the O-360-A4K and an STC for the AA5A, but no STC for the combo of AA5B with the O-360-A4K. It appears to me the only reason there is no STC for the Tiger's is there simply isn't a large enough market to make it financially viable. Assuming there was an STC, I also understand it is simply a piece of paper with absolutely no modifications to the airframe or powerplant. Is this accurate? If so, I would prefer to run 93 octane (91 minium) mogas when possible as I've been told this is actually better for the engine and won't cause as much plug fowling due to the lead content in 100LL (not to mention 30%+ savings on fuel). My question to the gang is how common is it for Tiger owners to use MoGas (answer this one directly to me rather than on list). 3. In the spirit of getting the cart before the horse... I need to locate a good Grumman savvy mechanic in the area. Is any one aware of a good A&P near East Tennessee or at least with in a couple of hours flying distance? There are a few good mechanics in my area, but none are Grumman savvy. Thanks in advance for any help or suggestions.

They are about the size of a short soda can. The shorter 48110-1 is fine. Change the oil every 25 hours WITH the filter. I recommend 15w-50. Lots of controversy here. Latest corrosion testing shows it's better. > 2.

The Reed vapor pressure of the auto gas is not suitable for the high altitudes and high temps seen in airplanes. I had a customer call and say=20he was stuck in Death Valley. His engine wouldn't run very well. He had flown to Death Valley from Reno on auto gas. I told him to transfer all the auto gas to one tank and fill the other with AvGas. That worked. I'm not a believer in auto gas. Plus, There is some concern over the sealnat in the tank deteriorating with auto gas. > 3. In the spirit of getting the cart before the horse...
