NOTE: Using oil other than service class SJ or higher, or extending oil change intervals longer than recommended can cause engine damage. Oil should be up to, but not over the "F" or FULL mark on the dipstick. See Figure 6-4. SE API RVIC 10W-30 Figure 6-2. 6. 1 E the FULL mark on the dipstick.

NOTE: To prevent extensive engine wear or damage, always maintain the proper oil level in the crankcase. Never operate the engine with the oil level below the "L" or LOW mark, or over the FULL mark on the dipstick. 4. Fill the crankcase with new oil of the proper type to the FULL mark on the dipstick. Always check the oil level with the dipstick in when checking oil level.
