Semi Synthetic Multigrade Piston Engine Oil SAE 15W50 (LW 16702)
The synthetic base stock performance provides for better cold temperature pumping and protection than single grade oils. In addition, the blend of synthetic and high quality mineral base stocks provide high temperature performance superior to that of other fully approved aircraft piston engine oils. The mineral base stocks help disperse lead by products of combustion, thereby keeping engines free of “grey paint” or lead sludge that can be a problem with some fully synthetic oils. The anti-wear additive system in AeroShell Oil W 15W-50 provides outstanding wear protection for critical camshafts, lifters and other high wear components.
