Update: 5W-30 & Heavier Recommended RoTW

[gasman4u]

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.

Yup. Financials determine everything

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.

Financials are determined by everything

Uhhh...ok. Your point or was there meant to be one?

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.

Ah...yes...my apologies on the misunderstanding. I should have just said "money" instead.

everyone just buy 5w30 ..... nuff said
3.5tt v35a bearings love it,

• Shear Stability (2:23 - 4:18): Contrary to the viral video’s claims, data shows that 5W-30 oils are actually twice as likely to shear out of grade as 0W-20 oils (40% vs 20%). When oil stays in grade, 0W-20 can provide equivalent protection to 5W-30; wear issues typically arise when an oil shears out of grade and becomes too thin.

Without watching the video, my gut is the base stocks in the 5W30's that sheared out of grade weren't truly PAO compared to a blend, etc. I'd also want to know more about the sampling of this graph and whether or not driving conditions, OCI's, and engines were similar across the results. I know - I should watch LSJr. video.

it's based on 10,000 oil samples that was sent in i think.

If you watched the video thoroughly, yes, 5w-30 will shear out of grade sooner, but even out of grade, it still provided great wear protection (even better according to the data), but when 0W-20 sheared out of grade, then the wear increased. Kind of a big deal.

Ya I’m gonna have to run 0w40 from now on

The key point is "IF"
1. If the 0W-20 stays in grade it is good and 0W-20 has a higher probability of doing than most oil samples, not that it has a higher viscosity than say 0w-30 or that 0w-30 doesn't provide more protection, but hasn't decayed as much relative to its ratings ... (points to a majority of 0w-20's being made out of good stuff .. PAO and Esters, whereas the much more common 5w-30 games in al sorts of brands and formulas from wallymart to motel).
2. This screen shot shows that a 30 out of grade offers better wear protection that an 20 out of grade.
