The following is from the Detroit Diesel Engine Requirements pamphlet (cant
find a date on it, but I have had the pamphlet for about ten years):
Two-stroke cycle engines Detroit Diesel Series 53, 71, 92 and 149.
"Where starting aids are not available or at very cold temperatures (0 to
-25F) even if starting aids are available, the use of multigrade SAE 15W-40
or monograde SAE 30 lubricants will improve startability. These lubricants
must possess a High Temperature, High Shear Rate Viscosity of 3.70 cP
minimum. These oils must be replaced with monograde SAE 40 lubricants as
soon as ambient conditions permit.
Exception: Do not use multigrade or SAE 30 grade lubricants in two-stroke
cycle marine engines or series 149 engines under any circumstances."
SAE 40, API classification: CF2 and Sulfated ash: less than 1.0%
Have a great day!
