Choose a viscosity according to the table :Synthetic oil meeting ILSACGF-2, API certification mark and APIservice symbol (shown at left) with SJ/CF ENERGY CONSERVING orhigher, is an acceptable oil at alltemperatures. Use of synthetic oildoes not alter required oil Recommendation F-20020406080100 C-30-20-10010203040 EXPECTED STARTING TEMPERATURE RANGE BEFORE NEXT OIL CHANGE**32 SAE Viscosity Grades*Air cooled engines run hotter than automotive use of non-synthetic multi-viscosity oils (5W-30,10W-30, etc.) in temperatures above 40 F (4 C) willresult in higher than normal oil consumption. Whenusing a multi-viscosity oil, check oil level morefrequently.** SAE 30 oil, if used below 40 F (4 C), will result inhard starting and possible engine bore damage due toinadequate Oil Level Check oil level before starting the engine.
