Many are probably going to ask....can I put this in my car?

Being an automotive engineer and testing cars for almost 25 years...Short answer is NO, especially in a Tesla .

Long answer: NO this is for marine 4-stroke engines, the description says on the jug and the Quicksilver Marine website : "It exceeds NMMA® FC-W® standards for non-catalyzed outboard, sterndrive and inboard engines" meaning it is not compatible with engines that have a catalytic converter/catalyst. So it probably has more Sulfur/sulfates that may poison your catalytic converter depending on the content Assuming you have a catalyst on your car and/or you don't care about smelling sulfur everywhere you go. FYI- A catalytic converter is like a sponge absorbing harmful emissions in the exhaust and catalyzes it to form less harmful gasses. However with excess sulfur the catalytic converter will absorb the sulfur and poison the catalyst, rendering it useless. At some point when it is overwhelmed with sulfur and with high exhaust temperatures some will be released all at once, smelling like rotten eggs.
But use whatever floats your boat.

What about using this in lawn mowers, snow blowers, 4 cycle but don't have a catalytic converter?

I just bought a 69 skylark 350. I've been told bc of the zinc content etc to use Diesel engine oil. Is marine oil similar? As a engineer would you recommend Diesel engine oil or marine oil in a older car?

Not an engineer but being this is oil and not a gasoline additive how would any if thise make its way into the catalytic converter? If you are burning engine oil, you have bigger issues. Still not saying this is okay for a car engine.

How about using this on a open frame generator?

Been using normal old 10w-30 in the Predator 212 I installed on my leaf vac for a couple of years, I figure this would be fine for that application? I usually do a change every 30-50 hours.

It's 10w-30 motor oil what are you guys debating. If your machine takes 10w-30 it will work. Synthetics is better but it's not $10 a gallon.

I run this in my Mercury and have for years. I only put about 50 hours a year on my motor so paying for the blend isn't worth it to me. Not supposed to use full synthetic due to possible moisture problems on marine engines. The manual calls for either mineral or blend. I picked up a few as this is a screaming deal

The 1 gallon Quicksilver 24w-40 is also on sale for $19. This is a deal too for the boating community, usually ~$35.

Another engineer here. In a perfect world, with no oil being burned as you suggest, I would tell you to look at the API rating requirement for you vehicle and compare it to the oil you want to purchase. Vehicle engine oil chosen by the OEM is not by chance and there is a reason why they chose what they chose. Without access to that data, we can speculate all day long, but won't really know. (Dirty Harry says....) SO, are you feeling lucky punk?
