Greetings folks,

Tuesday next week I receive my first ever 1994 Mercedes-Benz E320

decided to go with it after seeing all the testimonials about how safe they are.

It will end up replacing my old honda accord which was destroyed after a KIA ended up on top of it...... (long story)

So far after test driving it for 2 days, I love it, drives great, clean, no problems what so ever.

except 2 :D

1: the check engine light is on --- mechanic says they can find no reason why, everything is sound and working good, but they said that the sensor for it is extremely sensitive, and they wanted around 200 dollars to turn it off... ????

2: the gas peddle, is very very tight, is there a way to make it a bit looser ? normally it would not be a problem but if I'm going backward, or trying to inch forward, it's hard not to gun the engine! and wow what an engine they have packed into it!



Also -- any disadvantages to switching over to synthetic oil in such an old car ?



Hopefully it'll last me a long time, and I want to make sure it does :) so any tips, suggestions would be very appreciated!


Thanks in advanced!

First lesson to learn is to ONLY EVER take your car to a Mercedes mechanic.

Those without Mercedes experience won't have a clue, and you'll pay.

There is never ever a reason not to switch to synthetic oil.

Fluffy welcome, you don't say in your profile where you are and that may effect your ability to 'ONLY EVER take your car to a Mercedes mechanic'. For me personally that is a 775 mile trip, one way. In addition to several Mercedes enthusiast friends I ask a lot of questions and do a lot of searches and do most of the necessary repairs myself or provide direction and often parts to an independent mechanic I trust.

There are a lot of opinions and passion here in Benzworld and you must use your common sense and personal judgment to discern what advice and opinions best suit you, your situation and your vehicle's needs.

Good luck and enjoy the ride.

Thanks for the great replies folks! :)

As far as a mechanic, does anyone know any good ones in the Dallas/ftworth area, Texas. preferably Arlington ?

And I have no problem at all getting my hands dirty to work on my own car, providing I can find a good technical manual :)

Anyone know of any common ailments with the 1994 e320 that I should be aware of and watch out for ? :)


Thanks!

I would suggest for you to go search the W124 and the newer E class forums..:)

Your CEL is on for a reason. Who ever told you that there is no reason for the light being on is an idiot. Most likely it has to do with your exhaust system or a sensor on your exhaust system. Pull up the codes and figure it out!

You should switch to a fully synthetic oil (Mobil 1 or Amsoil) as soon as possible. There are VERY few cars that don't like synthetic's and your car is not one of them. Make sure to flush out and change all of the other fluids (along with their filters) while you are it. Be sure that the coolant isn't green! These cars take a clear coolant (Mercedes or G-05). Check to make sure the A/C is working before the high temps hit. Hopefully the condensor was already replaced the engine wiring harness was already done, otherwise those will be adding to your repair bill shortly.

I've never attempted to adjust the gas, so I can't help you there. The engine isn't really that big (try the E420), so it shouldn't be 'burning out the tires' when you mash the gas. Did you have a 4 cylinder Accord before? It might just take some gettin' used to.

Correct me if I am wrong but what I understand is that synthetic oil is leaner than dyno oil and so I can understand that if a new engine was fed with synthetic, it will somehow remain like new. But if it were fed with dyno oil first, it's thicker and so the engine would have to adjust to synthetic and thus some engine would leak ?
Again , correct me if I am wrong.

No, the engine won't leak if it isn't leaking now! Are you are kidding? And it's Dino (as in Dinosaur) oil, not dyno (as in dynamometer). There are millions of vehicles (mine) running around that started out on dino oil and then moved over the synthetic when it became popular and available at such a cheap price. Synthetic oil outperforms and outlasts dino oil in just about all vehicles. There are some vehicles that do not like Synthetic (mostly mico cars that share transmission oil with engine oil), but Mercedes isn't one of them. If wonderful low cost synthetics had existed back when the classic Mercedes were made, you could have bet that Mercedes would have recomended the use of them and most likely have installed synthetic at the factory.
