2017 and up 3.5 EcoBoost gave both DI and port injection which lessened the fuel dilution in the oil. I have 60,000 miles on my 2017 and have had zero problems I've done about 5 Blackstone oil analisis and they have been fine except one for which I just let the truck idle to warm the oil instead...

Dont know if the second sample you sent off to a different lab was from the same oil as the first sample or not. Reason I ask is on one of my samples from the same engine as your (2017 F-150 3.5 Ecoboost) I only did a driveway warm up and it showed 1.5 % fuel compared to less than .5% when I...

Originally Posted By: KJSmith Wow, your is doing better than mine. At 20k, I was on my 2nd change. My next report will be a while yet. Ford replaced my oil pan and put Motorcraft back in. That change is coming soon and then right back to the Magnatec. I guess your plastic pan was leaking? I...

Sorry forgot to write that this Magnatec is Semi-synthetic and the hours on the truck including idle hours are total hours for the life of the truck.

2017 F150 3.5 Ecoboost 6100 miles on 10W30 Castrol Magnatec 21,000 miles on truck, oil monitor was 39 % left with 630 total hrs and 99 idle hours with only a little towing on this oil. Went longer on this oil change due to a 1800 mile road trip. To recap, 1st is factory, 2nd is dealer bulk, 3rd...

Originally Posted By: Onug On your second sample with the fuel dilution...did you run the motor before the drain? And if so, for how long? The reason I ask is I had fuel for the first time in my last sample and it’s the only time I did a 5 min “driveway idle” before putting it up on the ramps...

2017 F150 3.5 Ecoboost 3790 miles 10W30 Penzoil Platinum 1st sample is Factory fill 2nd sample is dealer bulk with 3000 miles of towing 7000lbs 3rd sample is 10W30 Penzoil Platinum Oil in the sump now is Magnatec 10W30 which I will run for 5000 miles. Nice to see the fuel is lower in this sample...

Originally Posted By: Cujet Cut your OCI down to 5000 miles. That's too much fuel dilution. Remember that most of the fuel evaporates. That means your oil is being substantially diluted by non evaporating fuel by products. To back that up, you are clearly down at the lower end of the viscosity...

Originally Posted By: andyd Ahh, the hotrod M 20. The 528e with a de-tuned M 20 was more agile than the heavier 535i with the 3.4L M30. Never had an 325 is, but they must be a hoot in the twisties. PUL-LEEZ, don't ignore the timing belt in your refresh ! I have always done the timing belt on...

On mine I was towing in 8th at 2100 rpm about 63-64 mph. I locked out 9th and 10th.

Originally Posted By: ARCOgraphite I'm old and confused HELP! I have no idea what oil was run on your last sample. 11200 - 4900 = 6300. What is 6200 referencing? You mention dealer bulk, but then PP back in then Castrol Magnetec next. I'm not happy with the synthetic magnetic 5w30...

11200 miles on unit with Dealer bulk changed at 6200 miles, 10W30 Penzoil Platnum back in with a FL500 filter. Oil life monitor showed 36% left and 331 total hrs with 53 idle hrs. This last fill had 3000 miles of towing 7500 lbs from Michigan to Atlanta multiple times. As far as the fuel % being...

Ok had trouble loading the UOA, got it now.

Did this UOA for fun. Car above has been in inside climate controlled storage for the last 3 years. Oil was last changed 6/12/14 and oil has 2500 miles on it. Car is started at least once a month and allowed to come up to temp. Oil is Valvoline VR-1 20W50 racing with a Mahn filter. I didn"t...

Glad it worked out and thanks for letting us know what fixed it.
