I have an O-360 Mattituck (experimental) engine installed on my RV-7A. I have been using Aeroshell W100 Plus for more than 15 years. I have been using mogas solely for more than 10 years now, so no fear of lead deposits. This is my question: Would the use of fully synthetic (racing) oil be beneficial?
