SAE 30 is good for all-purpose use in temperatures at or above 40 ֯F (5 ֯C and higher); use in temperatures below 40 ֯F will cause hard starting.
Synthetic 5W-30 provides the best protection at all temperatures (-20 to 120 ֯F/-30 to 40 ֯C), as well as improved starting with less oil consumption.
Types of Oil to Use
