GEN 2 1st oil change / analysis

I had the first oil change done on my truck. There were 4920 miles on the clock. Ford calls for a 1 year / 5-10k mile interval using either synthetic or blend oil. I had the local stealership do the work, get a sample and I had it analyzed by Blackstone labs.

This engine looks about as good as we’d expect for a brand new engine. ...

No fuel dilution, water, or coolant contamination was found. Eventually this engine should look like universal averages, which are based on about 5,900 miles on the oil, but give it a few oil changes first. The TBN read 2.7, which is fine. Try 7,000 miles next.

The flashpoint was listed at 400F from the sample. I wasn’t expecting any problems and didn’t find any. They’re indicating I can push the change interval back a couple thousand miles. So, if you’re wondering about oil change intervals, there’s some real world data.

Good to know. Thanks for posting.

I just did my 2nd oil change at 4800 miles... planning to run this stuff until 10k, and send a sample to Blackstone.

First oil change was at 1800 and I went with Motorcraft semi-synthetic... this go 'round I went with Royal Purple

Good info. Nice to see something besides "I change my oil every 240 miles bc it's cheap insurance" nonsense.

And this was the original oil which isn't even full synthetic, which at about $30 for 6 quarts at Walmart, is a no brainer if you diy.

Probably one of the more useful posts I've read in a while.

But 5qt mobile1 full synthetic $11 (after rebate) at Walmart. Makes me wonder why dealers charge and extra $30-40 for a full synthetic change.

Is this a different lab than the one which was busted by a catch-can oil sample a couple years ago?

Good info here. Thanks for posting.

Cool. Thanks for posting some actual real world data.

Follow up question for everyone reading this thread. How many people who sent samples from their V6TT Raptor engine have had it report a problem or suggest a shorter oil change interval? How many have had it say everything was great and they can extend their oil change interval?

I'm not surprised they told op to go longer than 5k. Oil is way better these days. I'm doing whatever the computer says, ends up around 7-8... But i think out of curiosity I'll send in a sample. Is everyone using Blackstone? Or is there a different/better?
On a side note, i have a cng p71 that was purchased new. 230k on the clock and oil changes have been done every 5k w/motocraft syn. I'm thinking i could easily push to 10k on that car because at 5k the oil is still clear (natural gas burns really clean)
I did 5k because it was easy to track... Haha
mental note-test that oil too
