S3flyer Posted April 8, 2011 Report Share Posted April 8, 2011 Another summer question. Which oil to use? I use AeroShell Sport Plus 4 which says it is designed for all climates but it is also defined to be 10w40. The actual specs seem to work for my area but Roger's comment in a prior thread on 20w50 got me to thinking. Thoughts? Link to comment Share on other sites More sharing options...
Jacques Posted April 8, 2011 Report Share Posted April 8, 2011 According to the 912 Operator manual the 10w40 is good for -15°F to 100°F the 20w50 is good for +25°F to 100°F Link to comment Share on other sites More sharing options...
Roger Lee Posted April 8, 2011 Report Share Posted April 8, 2011 For me personally I use 20-50 any time the day temps are consistently 90+F Link to comment Share on other sites More sharing options...
