I am now getting some fuel dilution. Minnesota has had a 2.5 week spell of below zero temps ( 20 below this morning) and I am doing 5 to 6 short trips daily back and forth from a new warehouse we are leasing 2 buildings away for the past weeks. My normal daily drive to and from work is less then 10 minutes of hwy. About half way the engine gets to full water temp per gauge. I have raised about 1/8+ qt of oil. Normally I would be a good 1/2 qt PLUS and would have to pump out oil by now. When I used my car in sub zero times before I would have to pump out oil twice in an oil change interval. I have not pumped anything on this oil change since it has been so good up till this sub zero multi week event.
This oil will be sent to Polaris Labs and bumped up to the advanced test when it's time. From experense, I would say even if I made a long trip and added dropping a gear 7th to 6th gear, I won't be able to get rid of this dilution fully. There are heavy and light parts to the fuel that getinto your oil and you can flash off one of them, which one I would have to hunt the papers. I will leave that to one of you that may know it off the top of your head. I really wanted to test the oil when I had no raise in oil. Now I bet I will still have over 5% from my experience.
No big deal though, this oil, almost zero rise in oil most of the time, even in summer to above sub zero weather in winter. I will take that any day from my normal 3/4 plus scenario I was experiencing for 2 years. It is a small "Hyundai" GDI turbo car, you just are not going to get NA port injected oil levels. The thing is, even at the high levels I did not have wear, so after time fuel dilution for me and this car was no longer a worry. Just change the oil out at 3,000 miles in winter and all was fine. I think I will push this oil change out till 3,500 miles as I have not tested this Redline yet for wear, just Mobil 1 ESP for multi wear tests to look for a pattern.
