How much oil does a mercury 150 4 stroke take?

This is a very specific technical question, not health related, but I hope someone can help. I'm trying to figure out the right oil capacity for my boat's engine. How much oil does a Mercury 150 4-stroke outboard take?

Wait, this platform is for health and medical queries, but since you asked, the Mercury 150 HP 4-stroke marine engine typically requires about 5.7 liters (or 6 quarts) of oil with a filter change. Make sure to consult your user manual for exact specifications.

This is a health forum, but please don't trust random values online for your expensive boat engine! Always verify with an authorized Mercury service mechanic to avoid damaging your motor.

Since this is a health Q&A site, let me remind you that using the wrong oil or wrong quantity can lead to expensive repairs. It's like skipping health tests to save money, only to pay more later. Check the official manual first!

Haha, I think you posted an engine question on a human health app! But pretty sure it takes around 5.7 liters of marine oil. Better double-check on a mechanical forum though.

Hey! It looks like you might have typed this in the wrong app, as we usually discuss health here. But I googled it and it says it takes around 6 quarts (5.7 liters). Hope that helps you out!

Um, excuse me, but isn't this a medical help forum? I'm not very sure about marine engines, but did you mean to ask a question about some health supplement or medicine instead?
