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.

Marine oil is specifically designed to withstand the harsh conditions of a marine environment, with high levels of moisture and corrosion, making it significantly different from car oil which is formulated for the less extreme conditions of a typical car engine;
marine oil contains more anti-corrosion additives and is better suited for high RPM operation, while car oil is generally more focused on wear protection in a less demanding environment
Cannot find Yammy oil locally reasonably.
I usually pick this up at Walmart for about $22.

I spoke to a chemical engineer who works on fuels and lubricant's and he said basically the same thing. Also that all the additive packages share the same real estate within the oil. This Quicksilver marine oil has more corrosion protection additives and thus less for other lubricant properties to protect against valvetrain wear, low temp. sludge build-up, chain wear, piston deposits, fuel economy, etc... So this oil is not good for cars.
