CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.

Engine Oil Selection

For best performance and maximum protection under all
types of operating conditions, only use synthetic engine
oils, approved to MB 229.3 or MB 229.5, such as Mobil 1
SAE 0W-40. The FSS may not alert for an oil change at the
proper interval if an unapproved engine oil is used;
engine damage and reduced engine life may result.

Materials Added To Engine Oils

Do not add materials (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
