Ran out of headline room. Back in the late 90s every store had sae30 and 40 available in every brand they carried.

Today it seems like I only see napa,valvoline,castrol and wpp straight weights.

Wondering if some oil Co's have stopped making it?
 
Chevron Havoline, Castrol, Quaker State, Valvoline Pennzoil all make straight 30 grade. Beyond that I am not all too sure Exxon Mobil does.

According to same, its a full syn 10W-30. I think Amsoil states this...

Some do, but relegate them to HDEOs, rather than having a nominal SAE 30 SN PCMO and an SAE 30 HDEO. Imperial Oil and Petro-Canada seem to do that here. Conversely, Castrol makes sure ordinary monogrades (and even non-detergent monogrades) are readily available on the shelves.

Royal Purple monogrades, shown in the thread, are also available here.
 
I've never given monogrades a thought, but down in these parts, a straight 30 would make sense.

The couple of 0W16s that there are data sheets for indicate that they are essentially monogrades...scarcely obsolete.
 
Havoline, Quaker State, Pennzoil, Kendall, Delo, Rotella, Valvoline, Amalie, Warren Unilube, Warren Performance Products and Castrol all make at least 30 and 40, and some offer 50, 60 and 70. I can get several brands of straight weight myself.
