99 e300td questions

[pnolet]

Hi all,

Thanks for reading this. I have a 99 e300 w210. I'm wondering a few things, I'm getting dmn near 300k on this car and rather than listing everything ive done to itwas wondering
A) what oil should I be using for oil changes?
B) what service things should be done at this point since my fss has 300mi left before service and what others things will this be needing typically so I can know wether I've covered my bases or am missing something I.e.( trans service, common wear items, etc)
C) I have major turbo lag and I was wondering if this is the car, or can something be done?

Any info would be greatly appreciated

Hi, I can speak to a couple of your questions.

A few of us here use Mobil 1 15W-40 Turbodiesel Truck. In any case, always use a diesel rated oil to keep soot in suspension.

As far as turbo lag, mine has always had a huge lag if I floor it from a dead stop. It's like nothing happens for a second or two then it goes crazy. I've done a couple things to mitigate this.

One, I've adjusted all the slack out of the throttle linkage. Adjustment is under the hood on the TPS on the left side inner fender. Just don't take too much out or it won't return to idle. Secondly, I've adopted a "two step" acceleration process. I simply push it about half way, wait for a half second then go the rest of the way. This gives the turbo some time to spool. The problem is that the ECU waits for boost before it will allow full fueling and this is what you're feeling when it lags. The ECU programming is pretty aggressive to reduce smoke on acceleration which makes the lag worse.

I've always used M1 0W-40. Is sometimes labeled European Blend pending what stage Mobil is at in their constant re-marketing/labeling cycle. Was the factory fill when it was new.

Chips (ECU reprogramming), oftentimes improves turbo lag.

What about maintenance items? Do u still change fluid in a sealed tranny? What about other things that you would recommend at 300k?

Question b on my original post is all I still need answered

Transmission should be serviced every 50K or so using the proper approved fluids. Your car has a torque converter with a drain plug, so that should be drained too. That way you will get nearly all of the old fluid out. Look at the list of items that need to be done at the A/B services and do them. There are also some time related items like coolant every three years (again using the proper coolant), brakes every two years, etc. A search ought to bring up those lists and it is in your owners manual packet too.

Unrelated. Question but since I have some avid users here ill ask. I have a diesel lea k, it's not my delivery valves as I did those last summer and I can tell. However the lines hav nt been done but they don't seem to leak, it's leaking from around the ip not sure exactly where... Do you guys know of any common culprits besides deliv valves and clear lines?? Also since this will most likely require intake removal(it always does) what else should i knock out while I'm down there?

The side and bottom covers seal the main IP case which should also only have engine oil. Regardless, it's not unusual to see leaks at 300K miles.

Have you checked the chain? Jeremy shared an excellent how-to for a '96 E300.
