Am going away for two months and have thought about pickling the engine at least to some degree. I live in the Pacific Northwest and it will certainly be good and rainy while I'm gone, with temps usually varying quite a bit by the end of February.
Lycoming has it's recommendations, but I see that CamGuard claims you can add it to your regular oil at higher than normal concentration (8%) and use that as a storage oil.
They also say to spray the preservative mixture into the cylinders, keeping it at a temperature of at least 200 - 220 degrees. I'd like to do something simpler than that, like using a spray can of LPS-3. Is that a bad idea? In addition they even suggest spraying exposed surfaces like the starter ring gear.
Guess I'd just like to know what folks are doing and try to determine the minimum I can do without feeling too guilty. I did do a search on the topic but it's not conclusive and has been quite a few years since it was discussed, certainly since before CamGuard.
