Oil change, oil drain is like a cow pissing on a flat rock

[Point78]

I hit 1000 miles yesterday so did the first oil change on my 2.7.

This was the easiest vehicle I've ever changed the oil on. I had read the warnings on how fast the oil comes out so was prepared, with no issues at all.

(I did have it on a lift, and the big automotive style oil change galley/tank raised up right below the outlet.)

BUT-I think it would have been fine on the ground using a cement/grout mixing bin from Home Depot with a oil splash mat (Walmart, etc) placed in the bottom.

Thats what you need for working on the garage floor.... way better than typical oil pan.

On the Raptor, the sump is flat and the oil can be drained from the top via a siphon. I did my first oil change with a Schwaben vacuum oil extractor (manual pump).

After I couldn't get any more oil out, I crawled underneath and pulled the drain plug. Nothing came out. I replaced the plug, changed the filter (which is also up top) and was GTG. I use the same method on my German cars and they now have extractors that can also be powered by air compressors making it even easier and faster.

I don't know if the other engine offerings have a flat sump designed for extraction or not but might be worth looking into. Cow piss is no joke.

I've been using a good quality vacuum extractor from Harbor Freight for years . I also only get a drop from the pan when I do check occasionally to see if it is getting it all out. I originally purchased it to do the oil changes on the wife's Mercedes, but I've used it on a variety of vehicles over the years with the same results. I'm too old to be crawling around under vehicles for no good reason like I did in my youth, lol.

Send some of your 3k mile oil to Blackstone and have an analysis done. Unless you treat that motor worse than a redheaded stepchild you'll realize that short of an interval is just a waste of money.

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.

Before I bought the bronco I was in a '21 ranger and frequented the 5g ranger forum.. that's where I learned about Blackstone.. UOA's *period* actually.

Lots of folks noticed the oil level "rising" on the dipstick in those trucks over the course of the change interval and would send a sample to Blackstone who would provide fuel dilution numbers.. some higher than others.. anyhow..

How is what oil analyzers does to get their fuel dilution figures more accurate than blackstones process?

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 D7593 which is much more accurate. However they will only do this test if the used oil sample drops by 1 cSt from the unused viscosity (or you can pay $10 extra to guarantee they do it regardless). Usually they will always end up doing the test automatically for an ecoboost because there is usually significant dilution. It’s important that you tell them which oil brand/viscosity you’re using so they know what the starting viscosity should be.

Gotcha, interesting bit of information.. I like learning about nerdy tech science crap so thanks for the details.

Seems like the conclusion we came to on the ranger forums was that folks who mainly do short trips that don't always get the oil up to regular operating temp would have the most fuel dilution. Whereas people who frequently "fed her the corn" or generally always took longer trips had muuuuch less dilution.. little enough where it's not a concern.. "within spec" if you will.

Google says that between 100 and 122° gasoline quickly turns into a vapor and much past 122° it'll actually start to boil.. so seems to me as long as your oil temp spends a meaningful amount more time above 122° than it does below... Most of the dilution would/should/does essentially end up burning itself off through the PCV system.

I'll have to keep an eye on my temps. Back when I owned the ranger my commute to work was 30ish miles each way at an average speed close enough to 50mph.. so I never personally noticed my oil level rising or could smell gas on the dipstick.

Since buying the bronco though.. my commute got cut down to about 10 miles and closer to 35-40mph average... But seems like the oil temp always gets to 150° or so at least depending on ambient temp.. perhaps I'll send a sample in during my next oil change and see what's up.

The only sample I've ever had analyzed was the trans fluid when I had it changed a few weeks ago at 45k~. Wanted to know how much (if any) accelerated wear I've introduced to the thing with my 35" and 100lb per corner wheel/tire setup on 3.73 axles... Happily enough.. Blackstone says my sample was pretty much dead on par with other 10r's on their "break in fill".. with most of the other samples being changed between 32-35k miles.
