Supposedly not as good as that Delvac Extreme deal a couple of weeks ago (from a $/qt perspective as well as the "tier"). However, this is very good oil that will outperform traditional "car" oil.

These don't have zinc if I recall correctly so you'd have to add it.

This is a blend of oil and is not 100% synthetic. It is fine oil for what most people want but I wanted to mention know it's a blended oil product, as noted in the title.

I've used this for almost ten years and never read the container to know it was synthetic blend

For this curious, to be labeled as "blend" it only requires some amount of synthetic. There is no defined minimum ratio for the blend so it could be as little as 1:127

Depends on the engine and what they require. Google the engine model and look it up.

Get HD30 or HD40 oil, it's more expensive than 10w30 though

Is $27 really the regular price? must be on sale a lot. My history shows $14 the last two times I bought it. I use this and the 15-40 in my small engines.
