I made the mistake of checking my oil after the car had been warmed up. I don't normaly, but i figured what the hell. Well the oil level looked really low, so i put in two quarts of oil. The next day I checked it when the engine was cold and it was about an inch above the max fill line, right above where the dipstick goes from a flat surface to a round one. I'm not too worried about, should I be? :p

 

i always warm my car up till the oil is to its normal temp, then turn the car off and let it sit for a few mins, then check it/change it (hot oil drains better).

 

it's not as bad as what it could be in a piston engine, in a piston engine the crank is immersed in the oil and when it's running the oil can't be displaced and it'll blow a gasket from the pressure or the crank will beat the oil into a foam and it'll reduce the oil pump ability to pump oil and the oil cooling will be reduced. i'd drain a quart out just to be on the safe side, but it's up to you.

 

In the owner's manual, there's a large Caution box that contains the text: "Don't add engine oil over F. This may cause engine damage."

If it were my engine, I'd be draining some out.

I thought that you were supposed to check your engine oil level about five minutes after you turn the engine off (ie. not when it's cold).

 

I'd not be one to critique this, as gosh knows I've done my own stupid stuff... but I'd probably not have added more oil than is indicated for the total system capacity in the manual.

 

sure but if you check the dipstick ( which you should be doing with this car pretty regularly like every 3 fill ups minimum ) and it's low you should add a quart, he just happened to add a little too much.

 

Read the owner's Manual - it explains it all!

 

its a sports car aka a race car just feed it and it will reward you

 

Not really here to comment on the oil...but I must say its not often I run into another person who uses the term "Ack".... :D

 

sorry aka duh lol

 

also none as a

 

I'm curious how you came up with 2 quarts being the amount of oil you should add?

If the oil was at the low mark on the dipstick, it takes 1.8 quarts to take it to full. How low was it that you thought adding 2 quarts wasn't gonna overfill it?

I'm just surprised that you're surprised it's over filled now...

Also, to say "if it's low add a quart" is similarly silly - you should add oil until it reads full on the dipstick. The amount you will need to add to achieve this will vary - so make an estimate based on the knowledge that it's 1.8q from low to full and go from there.

 

It was really low, like the very bottom notch of the dipstick. 1.8 fills it so I figured 2 would bring it just right about to the top fill line. Well I was wrong!

 

Wow. Your literary skills are incredible. Are you still in 4th grade?

 

I can understand why the oil level is differenent in a recently run engine compared to a totally cold engine. I see in the manual that it wants you to wait at least five minutes after you shut down before checking the oil, but can you wait too long? Is there a significant oil level difference in an engine that has been shut-down after five minutes compared to one that's been cold for say five hours?

 

Oh crap, I just went to check it again, this time on a warm engine, it didn't make much of a difference at all. It's still about an inch above the max fill line and is even showing up on the round part of the dipstick a little bit.

I don't know what I was thinking, so spare me those responses, all I need to know now is if I should take the car 40 miles away to the dealership or if it's something that I shouldn't worry about. I can't drain the oil myself or I would. My understanding of the engine is that it uses an oil pump to lubricate the engine, so is overfilling it this much going to be a problem?

 

You haven't listened to a thing anybody has told you in this thread. Why are you still asking questions if you're just going to ignore the responses?

If the manual indicates it's going to be a problem, then yeah, it's a problem.

Are there not any quick change oil places near you rather than a 40 mile drive to a dealership?

 

The responses i've gotten are mixed, no one seems to really know for sure. Which is why I asked for clarification. If you were able to find expert advice in one of the above posts please point it out to me.

 

Read rotario's post Rupes. As per the manual, overfilling the oil can cause engine damage. The manual's written by the guys that made the car (or at least by people hired by the people who made the car). If they're not the experts, I don't know who is.

Oh, and Aseras has some good info in his post as well.

 

In the owner's manual, there's a large "Caution" box that contains the text: "Don't add engine oil over F. This may cause engine damage."

If you don't consider the owner's manual to be expert enough for you, then I doubt you'll find much help here at all.

40 miles to the dealershit? Just take it into a local lube shop and have them drain a half quart or so if don't want to DIY....no biggie.

 

That’s legal business, so when someone puts in 3 quarts of oil more than they needed to you can't come back and sue them for not putting it in the owner’s manual.

I understand putting in too much oil is bad, that’s not the point. The point is how much is too much, and is it worth a trip to the dealership for. I don't see why you’re getting on my case about this, it's just a big pain for me to have to take my car in so I'm looking for advice for my particular instance. Not just "overfilling the oil is bad as per the manual states." I'm sure someone here that knows the inside and outs of a rotary engine can tell me if filling it up around 1 inch above the max fill line is too much. Thanks.

 

Did you mean to say dealershit? lol :D
