Supertech CF-2 SAE 30

[N1887T]

Bought a bunch of this when it was discontinued. Looks pretty good for mowers and older engines. Rated API SG too.

Don't need much detergent when you are always adding oil to you're Green leaker Detroit.

ZDDP levels are actually reasonable, I wouldn't hesitate to use that in an IDI 4 stroke diesel (like the 7.3 in my sig), even though it technically isn't approved for CH-4 (or higher) for short OCIs (or quick leakers).

I bought a few bottles of ST HD30 for $3.12 each and its gone now.
Surprised to see it was SN Plus.

The less detergent the better, some sludge might actually slow some leaks down

I would only use 30wt in a DD 2 stroke in a cooler climate. Most people recommend and use 40wt.
