I have never gone past 5K. I wish I knew of the brake in procedure that is being recommended by members. It sounds like a good idea. Amsoil sells some brake in oil that I may consider if I ever buy another new car (or when I get my new TTV6 engine from the recall)
You don’t need break in oil. Just incredibly short initial drain intervals of the oil. You don’t even need to change the filter for these first few changes.

I did this for the first time (credit again to LSJr) on a Honda engine and the first change at 500 miles showed dark oil. Next change at 1500 was also dark. I did a third at 3k and changed the filter. I used pennzoil ultra platinum for this.

I changed my LC oil much earlier than the “recommended” 10k initially as well. Had I have it to do again, I’d mirror the intervals I did with the Honda above. Lesson learned. HTH

When I saw the info on not changing filters right away I was shocked. At least I have been using Amsoil filters.
 
Do not run break in oil in a modern car. That stuff is designed for race engines with solid lifters and flat tappet cams. The ZDDP content is unnecessary and harmful for modern TGDI engines.
 
oh oh..



This video investigates recent formula changes to Pennzoil Platinum and Ultra Platinum motor oils, specifically regarding the removal of their "made with natural gas" (GTL) base oil branding.

Performance Results: The lab tests indicate an 8% to 10% reduction in oxidation stability in the new formula compared to the previous GTL-based version
 
This has been a long time coming unfortunately.
 
my first oil change after switching to Penzoil 5W30. solid. will keep changing it every 3-4K.

this sample had 4100 miles on it. supercharged. no towing. mostly all highway and a few hundred off-road.
engine has 104300 on it.

Claude:
Wear metals — excellent
Contamination — clean
Additive package — looks like fresh, appropriate chemistry

TBN (Base Number): 3.27 — this is the one number I'd keep an eye on.
Fresh Pennzoil Ultra Platinum typically starts around 7-8 TBN, so dropping to 3.27 in just 4,100 miles is a fairly steep decline. It's not "bad" (labs generally don't flag until TBN drops toward 1-2, or below roughly 40% of the original value), but if you run this oil noticeably longer than 4,100-5,000 mile intervals, this is the metric that would run out first. If you're already changing around this mileage, it's a non-issue.

Something about putting the cart before the horse…
The thing is it's different carts and different horses. Sure, external events affect Financials. That is beyond a company's control for the most part. That wasn't my point though. My point was that internal decisions that they do have control over, for the most part, are determined by Financials. 2 separate things.

Maybe I misunderstood what you meant by “Financials”. I was trying to convey that financial results are a measure of internal decisions relative to running a business.
 
everyone just buy 5w30 ..... nuff said
