97' E320 oil change tips...

Hello. I recently purchased a 97' E320 w/ 100.5k miles on it and it is due for an oil change. I wanted to know if anyone has any tips on changing the oil on it? I read over the DIY oil change for the 3.2 V6, is there anything different I should look for/do for the straight 6? How many quarts of oil does my car hold? Should I be using Mobil 1 0W30 Synthetic? It looks like for it's last oil change it had 5W30 and I don't know what brand. Thanks.

0W40 Mobil 1. See DIY thread for discussion on recommended oils for MB etc. I believe it is 8.5 Quarts, see user manual. I would also change air filter and cabin filter.

Also, since yuu just clocked the magic 100K, there is recommeded 100K service such as spark plugs, belts, fuel filters, motor mounts, coolant flush, diff oil, recharge AC, power steering flush etc.If you have no service history, I would perform some of these recommended service just to be on the safe side.

See DIY for detailed oil change procedure, fairly easy to do.

I am hoping you had it inspected prior to purchase. Enjoy your Benz. I have owned mine for 3 years with no major issues. Hint: If you want to enjoy your MB, learn to DIY since dealers will screw you. Example? I changed motor mounts and trans mounts last weekenf for a total of $144, Dealer quoted over $965 for the same plus tax. I saved over $800 6 hours later.

I'm an Automotive Inspector for a living so I looked it over as much as I could. I didn't have a lot of service history on it except for recent receipts for oil change 5k miles ago, spring perches, 02 sensor, and tires. I just got the spark plugs for it and plan on doing the coolant flush, Diff oil, and ATF change very soon. Do they recommend changing all belts at 100k miles, from just looking under the hood the belts look like they're in very good shape and the motor mounts are good.

Put only 6 quarts in that car. The front timing cover likes to let oil out on that engine. At one time, Mercedes issued a TSB (the title is called Reduce Oil Level or somesuch) to keep the oil somewhere at the middle of the MIN-MAX marks on the dipstick. So start with 6 quarts and then adjust accordingly. 8.5 quarts is for the V-6 engines, not your inline 6.

Are there any oil leaks? Especially at the front of the engine, passenger side?

There are many threads about oil for your M104 motor on this forum.

The oil filter is near the firewall so it is a bit more difficult to access than in the V-6 but they take the same oil filter cap wrench (74 mm with 14 flutes). However, the exact size wrench is expensive as only Mercedes and a few Euro makes offer that. The Hazet is a 74.4 mm. However, many have used 76 mm with 14 flutes with no problem at all. The 76 mm is a very common size and you can get one from most auto parts store for about $5. You probably need a little extension or a swivel joint to reach the filter cap to loosen it. I only hand tighten (pretty good) it when install the filter cap.

You can choose to either drain the oil or suck the oil from the top. The oil filter (it is just an element) comes with a copper washer for the drain plug and a large rubber o-ring for the filter cap.

Other than that, it is no different from any other oil change.

If you have other question, please post back. Many (me included) here have done this on this car.

Belts last a long time but inspect to see if there are any cracks or cuts. The tensioner and the tensioner pulley do seem to make noise at some point.

Yes, yes, yes! Only fill that car up to the halfway point between the upper and lower marks on the dipstick. I think it takes closer to 6.5 quarts, depending on how much oil you get out of the car, but if you put 6 quarts in you can check the level when you're done and add as required.

As far as viscosity goes, in my experience the inline 6 runs hotter than the V6. I'd want at least a 5w40 in the car. I'd be hesitant to run a 0w40 only because the motors are a little leak-prone in a couple of areas. I actually run a 5w50 in mine year round, in the C280. You don't have to run a synthetic in this one (unlike with the 1998 and newer) but you get more benefits with a synth.

I hope your does not have any leak.

Even when they do, you will probably not see on the garage floor because:

1) Usually it is just a very slow seep.

2) Mercedes innovated the "oil diaper" , aka, the sound encapsulation panel on the bottom of the engine. You know if they cannot keep the oil in the place they should be, they can at least put up a diaper for it.

Sorry I have to rub this in. I have owned three inline 6 powered Mercedes and all seeped at the front timing cover.

Synthetic will protect your engine better and should give slightly better gas mileage, but it's not required.

Ever have a question about oils to use, just check the stickies for the "approved oils" list.

Personally at that mileage I'd want a 5W40, 30 is pretty thin.

Take care and enjoy the ride,

I also have the E-320, but a '96' (inline 6 w/ 144K)
Owners manual sez, 7.4 quarts. Agree with the points of not overfilling this car. Start as others have posted with less and fill as required. This car is hard to read on the dipstick, and it takes a Loooonnnnggg time for the oil to settle to the pan, so the dipstick will register right. I always go back and re-check for the next 2 days, to get it right. Also make sure the car is sitting dead level when you check it.
Draining the oil on this car is a snap, since the drain plug is at the front drivers side of the engine. It's in your face when you get past the front bumper.

Been a Castrol user since the '70's and run many vehicles way past the 200K mile mark. I had a S-10, with 275K , sold it and watched the new owner run for another abusive 2 years. It was a construction truck, and never saw a easy day. Also a old 71 Grand Prix, with over 375K, until the rings finally gave up. No major repairs, and I am a hard driver. I don't baby my cars on the road, but at home is a different story.
Synthetic is not needed here and if the car was run on dino oil, I would be reluctant to go over to synth. Heard bad stories in doing so. If you have been running synth, stick to it. It is actually superior (especially on those winter mornings).

For me,
I usually run a thin oil on cars with less than 100K on the clock. After that time I always kick it up to 10-40 (castrol), since the tolerances open up a bit. If as the car gets to the 200K mark (where most owners won't trust a car anymore) I look for oil consumption, and also the dreaded "Blue Smoke"! If I even see a puff of the dreaded "Blue Smoke", I up the oil again, to 20-50w. Then usually I can get yet another 75-100K before the engine gets funky.
Be religious on the oil changes, and wether dino or synth, You should be fine.
