I know you don't really have to ask for opinions on this forums, you'll get 'em anyways, but...
Just a few days ago, I finally bought my dream airplane- a Cessna 180. This one, a 1953 model, has a K engine with about 1150 since reman. The seller put on about 1100 of those hours, and has been doing 35 hour oil changes using Aeroshell W100 and Camguard. The engine has great compression, and goes through very little oil between changes. I've always used Phillips XC20-50 but since he's had such good results with Aeroshell I'll be using it also. But I'm not sure about the Camguard, so I thought I'd ask here about it. It's about $25 per pint-sized dose, so adds almost 50% to the cost of an oil change. Does it really help, or is it just another snake oil additive?
