Substitute for Valvoline 30 Weight?

[dwendt44]

The Wal-mart I frequent used to carry the 10w30 Rotella but haven't stocked it lately. No demand?
I thought I saw the straight 30 weight some time ago as well but it's not on the shelf in the last few visits.
Bummer. Was looking for either of those for lawn mower use.

I'd take Rotella 15w40 over the Pennzoil HD 30 here, but that's just me.

I've had no problems to speak of, but I'm wondering if there's a good substitute for the straight 30 weight. It's kind of a pain in the *** to find.

Any thoughts?

Thanks for your help.
Delo 15W40 in my sterndrive!

It seems the Walmarts in areas near the Great lakes here seem to carry more marine grade oils. Mine carries Pennzoil Marine and sometimes Merc 25w40.
