I would change it now because there are a lot of wear abrasives picked up by the oil during the first few thousand miles since new, which can in turn cause further wear in the engine if left in long enough. It’s not a big deal if you can’t. I’d just try to average no more than 5,000 miles...

https://bobistheoilguy.com/forums/threads/blackstone-and-fuel-dilution.357356/ Blackstone uses an inferred fuel dilution test by measuring flashpoint that is notoriously inaccurate and usually under reports by a large factor, but is cheap to do. Oil Analayzers uses gas chromatography test ASTM...

Don’t use Blackstone, use Oil Analayzers so you can get an accurate fuel dilution measurement. It’s one of the most important things to know from an oil analysis on an Ecoboost. It’s about half the price of Blackstone and 10x faster turnaround too. https://www.oaitesting.com/

It must take something extreme in terms of temps or idle time to shorten the life at all off that basic formula. I’m a little bit skeptical but I know not to question you. For instance I had one Bronco that had run 250 hours when I changed the oil (from the trip meter) and another that had run...

The mileage estimation to next oil change in the app is based on how many miles per day you’ve been driving lately, on average. If you only drove 800 miles in the last year or so, it thinks you will need another oil change in a year, and that you will only have driven about 600 miles in that...

I’m using Valvoline Restore and Protect 5W-30. It’s OK but I’m not sure how I feel about these high molybdenum oils as I think they’re prone to deposits in low flow areas of the engine. Good for piston rings though. It does get diluted to a near 0W-16 grade in my engine with the fuel...

Mobil 1. And I would go with the ESP 0W-30 from their lineup.

I just did this on my 2.7 OBX with Forscan. I did take all the old fluid out of the reservoir with a turkey baster and refilled it with a pint of fresh DOT 4 LV before starting. When you open the ABS Bleed maintenance procedure in Forscan it doesn’t mention anything about going into Brake...

Any theories on what might've caused this?

I have the studded non-RT Duratracs as my winter tires here in Alaska. They’re very good. I do some snow wheeling with them and they’re excellent for that as well as driving on icy roads. I have no complaints.

This was the First 5,000 mile interval with the Valvoline Restore & Protect on this Bronco (the Wildtrak). The fuel dilution is high but I don’t think it’s a fuel leak as the analyst indicates. Pretty cold here this winter with near daily sub zero cold starts, some at -20F. This supposedly...

I’ve got pretty bad fuel dilution too. There were a lot of -20F cold starts this winter but like you said it didn’t seem to be quite as bad when the Bronco was brand new. 4.6% on this latest. I’ll be eyeing the ESP like you or some kind of 40 grade if this keeps up.

Well, I was > 5% dilution on my last Polaris UOA too. This was only after 900 miles to boot, and I make an effort to limit idling and short trips. There’s no getting around doing some -10F cold starts after it sits at the work parking lot all day though, and I think that’s what’s contributing...
