Car literally will not crank much in the cold
Hi Guys,
Sorry if this has been gone over 100000 times but I'm in need of some advice. 82 240D (runs great, typically starts immediately in all weather conditions) Went out to start the car this morning knowing that several factors might contribute to a harder start than usual. - Have B20 Biodiesel in the fuel tank - Have Rotella dino 15-40 in the crank case It's about 9° here in Philly and I am street parked. Car cranked and cranked and cranked (very slowly) omitting some puffs from the tail pipe until the battery died. I called AAA and the guy (whom asked where the carburetor was) gave me about 5 minutes of his time with a portable jump pack. He tested the battery and told me it was OK (its like two years old) and that the motor was most likely turning over so slowly due to frozen sludge in it Anyways, any advice on how to get this thing to crank quicker? Am I SOL for having B20 in the tank and 15-40 in the crank case? Should I just get my own jumper pack? I'm curious if maybe his jumper pack just kinda stunk? Thinking maybe I'll throw some additive in the fuel and try and jump it off a running vehicle? |

Synthetic oil and multiple glow cycles. Block heater if you can.

Yes, agree. I changed the oil in my 1981 300SD to 5/30w(as I remember) and it helped starting in cold weather quite a bit.
You probably just need a jump from a real running vehicle after you glow the plugs. It needs to spin decently fast. |

15w-40 is fine if it is synthetic. A topped-off battery is necessary since battery internal resistance goes up sharply in very cold weather.
I use 15w-40 AMSOIL and my engine is running smoothly within the first revolution after i single glow cycle. |

All above is great advice. I'd go synthetic for the winter only, such as 5W-40 Rotella. Did an experiment once, put a quart of synthetic in the freezer overnight, it poured almost the same as the quart left at ambient room temp.
Glow and listen until after the light goes out (about 10 seconds?) and then you hear the relay click open...crank immediately when the relay opens. Use fuel treatment designed to prevent gelling...been there done that too... Good luck!!!

#1, drain the oil and fill with cheapest diesel 5w40 synthetic. Around me, wallyworld has deload syn 5w40 for about 20.00 a gallon...
Next FULLY charge the battery. Then remember, ya need to wait for the glow plugs to click off before trying to start, it's about 45 seconds on pre86 cars. In very cold weather, below 15F, a second glow cycle can make an easy start... Of course... bio can make an issue, but B20 shouldn't cause any harm above -15... a can of white bottle power service will safely treat a tank of B20 to handle down to around -15... if you happen to have summer blend in the tank. Get an old fashioned incandescent bulb equipped lamp and set it on the injection pump plugged in overnight to help, if your block heater isnt working...

Check valve adjustment.

*2 on the 5w40.
I used to live in the mountains of central new york. Weather was regularly single digits or below zero. If you have access to a garage, do the following: 1. Get 5w40 in that poor girl. I'd just do a full oil change. 2. Make sure you have a fully functioning glow plug system 3. Do a valve adjustment. I used to do a valve adjustment and oil change switch to 5w40 yearly every Thanksgiving to prep it for the cold. One year I forgot and the engine was hard to start every now and then when it got close to 0*. Around March I would switch back to 15w40.

A 616 or 617 starting at 9F with 15w40 in it would take a REALLY good battery, REALLY healthy starter, and REALLY good compression/glowplugs on that engine. Otherwise, likely not happenin.
1. 5w40 synthetic oil 2. New glow plugs 3. Valves adjusted 4. Healthy starter (makes a huge difference) 5. Healthy Battery 6. Glow for full 30+ seconds before cranking With all that in order it should fire up pretty quickly at 9F if the engine is still healthy.

Also the starter could be getting tired. After the starter failed in both my previous OM617 diesels the new starters cranked the engines NOTICEABLY faster in both cars.

If you're in a pinch, topping off with some Marvel Mystery Oil will effectively give you a lower viscosity of oil. Would help clean out any sludge and free up stuck rings also (worked really well for me).
