I have a new to me 2016 F150 with the 3.5L ecoboost, vehicle has 45k miles. I have never had a vehicle that had a computer that determined when oil should be changed based on hours/miles/rpm's driven, which I believe is how this vehicle determines when the oil should be changed. I changed the oil about 3 months ago, and have put about 3500 miles on it since then. Used the appropriate K&N filter along with Mobil 1 full synthetic. The computer tells me the oil has 75% of its life left, normally I change every 5k miles unless something makes me think it needs it sooner. I just checked the oil and it seemed much darker/blacker than I would have expected. The oil I removed was pretty black when I changed it, I have no idea if the p.o. used synthetic, dino, or what. My normal schedule would be to change the oil in 1500 miles, I think the oil life is 2/3 used up, however the computer says it still has 3/4 of its life left, but it looks like it ought to be changed soon to me. Wondering what you guys thought. I'm inclined to just change it but wondering what you guys think. Thanks

I dunno, I thought this post was about the Yamaha F150 I change the oil in my trucks every 10k miles, but I use full synthetic. My trucks are programmed to tell me to change the oil every 5k, so I just reset it and change it at the next interval.

X2 on the reset on my Ford F150. Mobil 1 full synthetic I change every 65 to 7500 miles

So you think it's ok to ignore the oil being blacker/dirtier looking than I'd expect after 3500 miles and stay with my regular oil change interval?

synthetic always looks black in a short while. Now if your using the oil from a Ford dealer It's not full synthetic and you will need to change more often every 3000 miles.
FYI I also reset the gauges on the boat because I use Mobil 1 oil. This season I had about 135 hrs on my oil which really isn't sh!t. I'm not going to toss out $70 worth of oil over an extra 35 hrs. However I do drain the oil at the end of the season because I won't allow dirty oil to sit on the crank case all winter, thats not a good thing.

Yep Mobile One HIGH Mileage in my F150s.
Full synthetic and 10k miles is a safe bet in any vehicle.
If you dont believe me send it out to Blackstone for an oil analysis.

I went with the high mileage mobil one today. It has some sh!t in it to help keep seals from cracking, drying out. Did you see any change from Blackstone while using the high mileage blend ?

My testing came back pretty good from the last season, although I didnt use the best viscosity. This year I switched to High Mileage 10w 40. I'll be sending that out for testing this year and can compare all 3 - regular Mobile One 10w 30, High Mileage 10w 30 and High Mileage 10w 40.
Thought being the higher viscosity 10w 40 provides better viscosity to account for any fuel dilution of the oil lowering viscosity.
Yep high mileage helps to preserve and seal up any cracks in the seals. High Mileage also has extra additives to improve the wear scar rating helping to keep your internal parts lubricated.

10w 40 thats interesting, I've always used 5 or 10w 30 as recommended by Yamaha. My concerns with 10w 40 would be starting in cold weather and the oil being so thick. But I like the thought of higher viscosity for the summer.

Fuel dilution in the oil breaks down the viscosity and we know how these engines can "make oil" so 10w 30 becomes something less and seeing how I often run over the 100 hr service interval maintaining adequate viscosity is important.

Well that sums it up nicely. On the next oil change 10 w 40 it is thanks. Man we derailed the sh!t out of this post. Lol

The thought also is that the thicker oil will better coat/stick to the internal parts.
I'll let you know if I see any issues during the cold months before I put it up and what my oil analysis looks like by comparison.

I would run motorcraft oil myself. thicker viscosity oil doesn't mean better. changing the oil at 3500 miles is a waste of money but if it helps you sleep at night, it's your money...

It's all ball bearings nowadays. Now you prepare that Fetzer valve with some 3-in-1 oil and some gauze pads, and I'm gonna need 'bout ten quarts of anti-freeze, preferably Prestone. No, no make that Quaker State.
