Question Posted Wednesday November 5 2008, 7:23 pm
I have a 1991 300E Benz. It drove PERFECTLY until I put synthetic oil in bcuz my oil lite came on. After I put the oil in it overheated I put n 1qt. Instead of 3 like I was proly supose to. After it overheated I let it cool down then at nite I added 3qts. I drove home nd when I got close to home it overheated again. Nd it made a knocking noise when I tried to start it. Now its been sittin since the 27th. It also started to leak which its NEVER did b4. Las time it needed oil I took it to jiffy lube, this time I jus didn't have the money. I have no clue wat to do to fix it, hopefully it won't require any expensive repairs. Any feedback wud be great. Thanks
Putting less than the required amount of oil in was your first mistake, when engines don't have proper lubrication, things go very wrong very quick. Make sure to maintain a proper level, which you can check with the dipstick. Keep it in between the two lines. And I may be wrong, but I'm pretty sure that the 300 takes a lot more than three or four quarts. My 2.2L takes five quarts, so you'll probably need much more. Check the manual if you have one.
Next: did you change the oil filter as well? that should be done every change.
Make sure that you tighten the draining nut snugly when you are done draining the old crap, that's the easiest explanation for your oil leak.
More than likely something is wrong in your engine, something that needs to be fixed by a shop. When your engine overheated it very well could have warped the head, or fucked up a piston. A warped head would explain it, but Im not making any guarantees.
Go to a shop and at least have them look at it, and give you a quote on what it would cost to do the repairs.
Moral of the story? Kids, if you don't know what your doing, don't do it, or get help. When something is wrong, stop, figure out whats wrong before it gets worse. One small mistake could cost you.

The leak definately needs to be checked out. as for starting the car, before you turn it on, pump the gas a couple of times then hold it down halfway while turning on the car, this should start the car. you might have to do it a couple of times before it actually works. if it doesn't after a couple of times, hold the pedal down all the way then start it. it pumps up the car. hope something of this helped [ es's advice column | Ask es A Question ]
