Hello Terrence, If you use 100% synthetic, just be sure not to use leaded aviation fuel. The 100% synthetics leave what is called, I believe, "grey paint". Seems that they don't scavenge the lead. Mobile Av1 was taken off the market several years ago because of a large number of problems and law suits over this. Todays solution seems to be the semi-synthetics such as the multigrade AeroShell and more recently Exxon Elite. I have used the Exxon Elite in my engine for almost 1,000 hrs (except for break-in). It has performed well and allowed easy cold starts. Has all of the advantages that you site above and is designed for leaded avgas. Bill Harrelson 5zq@cox.net N5ZQ 320 950+ hrs N6ZQ IV 1%
