Update: 2nd Blackstone Oil Analysis Results (2.7 Bronco) @ 4,000 miles (3000 on Oil)

[HeliPilot]

Doubt I’ll ever wind up with the add-on rating, but I’d love to take a lesson or two some day!

You should. It's a completely different, yet familiar, form of flying. I have ratings in both FW and Rotorcraft. I much, much prefer hell's. Flying is always challenging. Both hands and both feet are working in constant coordination. Though, you do go further faster in FW!! Took me 22 flight hours to ferry a Robinson helicopter from the manufacturer in Torrance Ca to Detroit Mi.

Our neighbor is a Grumman owner. They attend every get together. You ever attend? You may know them.

No, I don’t get to get togethers…….guess I’m not very social.

Thanks for the info. It maybe helpful long term to update your first post with where the updated post are when you get 10 pages deep it will suck to try and find all the updates.

Ha, have a coworker who has a similar story ferrying a J3 Cub from Canada to Houston.

I do have a decent amount of time in the back of the big boy Sikorskys and the odd AW 139s for work, seeing nothing but ground out of the front windscreen when they get going always makes me clench a little

That always gets my passengers too!!!

Updated with 2nd oil analysis

You still using Costco’s pure synthetic? Is it even rated for these engines?

I think running those costly oils and changing often is overkill, but If I was going to go cheap, I think I'd probably just stick to the factory oil. Otherwise at least something that meets the specs. Based on my notes I had made a while back...

WSS-M2C961-A1 Factory oil part number
Pennzoil Platinum Full Synthetic
Oil needs to meet
GF-6 and API SP standards (for Turbos and Start Stop)

I've not seen anything in my research to make me think Costo's oil is an inferior product. It's approved for the two standards you mentioned. Regarding oil change intervals, I may extend them a bit in the future, but I haven't decided. It's cheap insurance.

Nice! I'm a bit surprised, I wonder where Costco gets their oil from?

I was just thinking with the lower viscosities that maybe it just wasn't up to par, but if that spec sheet is true...it should be solid.

I'm not on my laptop right now to be able to look at this site better, but I found this a while back and found it very interesting. I think Kirkland is on there but I'm not sure if it's the specific one

…….actually, truth be known, engine failure at 500 feet is worse…much fewer options.

In a fixed wing altitude=life

Neat website. Yep, Kirkland Signature Synthetic is the one:

So interesting enough, according to the website the Kirkland doesn't meet the GF-6 however their data is from 2020.

Also, I compare the viscosity between the Kirkland and the equivalent Pennzoil Platinum.. kirkland = 11.02 with an index of 176 and Pennzoil = 9.9 with a 161 index.


So you went down from an 11 to an 8.5. Not sure if that's normal, or if the kirkland oil is breaking down faster then it should.

I don't think they listed the exact oil I used for my oil analysis but after 10k miles, my mobil 1 only went from 8.8 to 6.7.

Sonyou went down from an 11 to an 8.5. Not sure if that's normal, or if the curse of oil is breaking down faster then it should.

Lol. You had me worried, so I double checked my jug.

Just got my break-in Blackstone report. Posting for others reference.

I used Kirkland in my wife’s car. However, it went from 29.99 for 10 quarts to 33.99 last month. Not as much as a smoking deal as it used to be but still pretty good. From testing it appears identical to Walmart super tech 10k synthetic which has good ratings and is made by Warren.
