Backstory: Normally, I do my own oil changes. I never have any reason to contemplate damage caused by overfill because I know how much goes into my cars. However, today I needed to take it to my buddy at the dealership who did the oil change for free (I brought his tech the oil and filter) because we are getting ready to go on vacation tomorrow and I don't have the time or desire to break out the ramps and do an oil change in 100 degree heat.
My 2017 Elantra 2.0L takes 4.23 quarts of oil with drain and filter change. I supplied the tech 5 quarts and a filter for the job. Well, he dumped in all 5 quarts, overfilling by 3/4 quarts. I did a search on here for overfill and I feel like this is right in the middle of "safe to run" and "too much". It seems like a 1/2 quart is just fine and a full quart is too much. My question is, do you think this extra 3/4 quarts do any damage? I didn't catch it until I got home when I thought it was weird that I didn't get my remaining quart back.
