Same here, I have more trouble getting fuel through filters.
Well,,,, the truck on anything below 60 just flat won't crank anymore. It's got tons of miles, slap worn out, and is even slow to crank in the summer without glowplugs. Since it dropped off cold I have to pull the truck If I want it to start. Doesn't matter the fuel. It's either going to be totally replaced, or get a new engine this spring.400,000 plus miles on it. Little blue still has non functioning preglow. The controller was bad on the car when I bought it, swapped the one off the 350SDL onto it, it worked for a good while, but the controller kept the plugs lit too long and burnt them out just before the temps started getting too cold. May get around to replacing them tomorrow, or the next day.
BUT, when the glow plugs were functioning, we got one good cold dip below freezing, and the cars started just fine on a high percentage of 80-90 gear oil, they just wouldn't run down the road on it.
Last winter the cars were not mine yet, but the truck had acceptable crank times, and would run fine on greater than 90 percent as long as I was easy on the throttle. High speeds or hard acceleration would cause the filter light to illuminate and the engine would start starving soon after.
Same for the tractor, I had it on a 80-90 percent mix. It got cold several days ago and I needed to do some bush hogging. Since it has no glow plugs it needs ether in the winter even on D2. I ethered it and cranked it up and ran the throttle wide open. About 30 seconds after cranking it it quit, and I had to bleed the fuel system to get it going again. Once I got it started I ran it for several minutes at a low throttle setting until I could feel heat coming from around the cowling. Once the tractor was up in temperature I was able to slowly bring it up to speed. It has no thermostat, and a good radiator, so even in the summer it rarely runs above 130/140. The next day it was the same thing. Dumped a couple gallons of stale gasoline in it and it does fine now.
One thing I have noticed though, in cold temps and several minutes of idiling or low rpm running it will start to spit goodly amounts of unburnt fuel out the exhaust. Enough fuel will come out that when you rev it back up it pours several ounces out the exhaust that accumulated in the muffler. I now have a huge mess all over the hood and exhaust. In temps that are low, it seems to run fine, no apparent missing, it just starts to spitup if you are not working it. If it's really cold it will still spew small amounts of fuel out the exhaust unless it's under load. Now once you put a load on it, it starts doing very well, and will build enough heat to burn off the fuel that ran down the muffler. I have decided to put it back on d2 until summer, unless I can work it hard I feel there is too much risk of coking if I don't.
