I don't know if anyone has experienced this but here is what is happening.I have filled my last 2 tanks of fuel with Shell premium diesel just to see if there is a difference.I have noticed that as the weather is warming (12 celsius) that on startup the engine is stumbling when I give it a bit of gas,almost like its missing.I let it warm up for a minute or so and then drive off.The low throttle acceleration is poor.After driving for about 10 minutes the temp gauge was about 1/2 way to normal when I went to accelerate in traffic the car almost stalled,kind of like a gasser when the ignition cuts out.After full warm up things seem normal.Do you think its winter fuel (don't know if they have changed over yet or when that happens).
However the stumble in traffic was really pronounced.No check engine light.
