Daily short driving distances, Blackstone engine oil analysis...

[710-oil-614]

The 2.5L hybrid engine does not have DFI, or high pressure fuel, the fuel/air mix goes through the intake valves, so, that's fine. As for fuel in the oil, I don't know how much it can accumulate in the crankcase between oil changes. Test it at the next oil change...


There are 55 top tier fuel gas stations in the US, not including PR, under various names. That includes well known brand names and Costco, Kirkland, QuickTrip and others, The latter one just buys the brand names at whole sale, since they do not make their own. I believe that my Maverick has been filled up with top fuel all these time. Now, if you'd going to tell me that I should not mix the different additives with randomly selected top tier fuels, you may have a point. Even that is unlikely in my view and then again. Regardless of the top fuel, it does not matter since it does not touch the EB 2.0's intake valve.

I'm not telling you do to do anything other than what you want to do to your Maverick.

Ford recommends filling with Top Tier fuel, that is what I do.

Hmmm. I just got my report back. Second oil change, 7800mi on synthetic. My commute is about 30 miles one way, plenty of time to get to operating temp. My fuel in oil percentage was 2.5% on my ecoboost. I did just idle it a bit before the oil change

To get the most accurate results for an analysis, you should preferably change the oil (collect the sample) after an extended run where the engine maintains NOT (normal operating temp) for at least 20 minutes. Backup method would be cold, AFTER a 20+ minute trip. Cold Idling for a few minutes prior is never recommended.

I am not trying convince you to do anything different either. Do what you see fit for your Maverick.

My point was and is, that Ford does not name any of the top tier fuel companies in their recommendation. That and the fact that there 55 top fuel gas station in the US. Since there's a Federal requirements for additives, the chances are that any of the gas stations are in the top tier fuel.

My Maverick gets super unleaded from top tier fuel gas station such as Shell, Mobile, Citgo, Exxon and Sunoco, depending on the price. These are the brands available in my neck of the woods, we don't have others like QuickTrip...
