This prevents the metal-on-metal contact that leads to premature wear, protecting the crankshaft, pistons, and connecting rods from the stresses of combustion and friction. Using a modern multi-grade oil in these specific engines is not necessarily harmful, but the straight-weight formula of SAE 30 aligns perfectly with the engineering tolerances and requirements of this hardware.

Multi-Grade Oil The decision between SAE 30 and a multi-grade oil like 10W-30 often comes down to climate and manufacturer recommendations. SAE 30 oil excels in these high-temperature environments because its viscosity is optimized for warm conditions.
When the engine reaches its operating temperature, the oil thins slightly to ensure it flows freely through the galleries, yet it remains thick enough to cling to critical moving parts. The simplicity of using a single-grade oil removes the guesswork often associated with seasonal changes, making it a popular option for routine maintenance.
