oil type for 8v 92

[mbulriss]

Hey Rob,

Yeah, we're saying the same thing. Kind of funny that the DD link to
their lubricating standards on their Motorcoach front page is to their
older brochure from 2005 (7SE270 0510). In that one they list a
table in Section 2.2 that basically says 40wt preferred and 50wt
secondary.

Then they go on to say (in part):
3. For continuous high temperature operation (over 200° F or 93° C
coolant out), the use of an SAE grade 50 lubricant in DDC two-stroke
cycle Series 53, 71 and 92 engines is required. SAE grade 50
lubricants are also required for all Series 149 engines where
ambient temperatures are above 95° F (35° C).
4. At ambient temperatures below freezing (32° F or 0° C), sufficient
starter cranking speed may not be achieved to start the engine with
SAE 40 grade oils. Where starting aids are not available or at very
cold temperatures (0° F to -25° F or -18° C to -32° C) even if
starting aids are available, the use of multigrade SAE 15W-40 or
monograde lubricant SAE 30 will improve startability. These lubricants
must possess a High Temperature – High Shear Rate Viscosity (measured
by ASTM D 4741 or equivalent) of 3.70 cP minimum. These oils must be
replaced with monograde SAE 40 lubricants as soon as ambient
conditions permit. Do not use multigrade or SAE 30 grade lubricants in
two-stroke cycle marine engines or Series 149 under any circumstances.

Send me the link to the 2007 revision when you get a chance. Save me
from searching their site! Thanks.
