Default Deep Dive on Oil Comparisons

https://540ratblog.wordpress.com/

Draw you own conclusions, but this a really good deep dive on oil performance and head to head comparisons. Lengthy, but you can read it all or skip to the bottom line.

FWIW I thought #4 was fascinating being a "green" product vs conventional oils.

Interesting that some of the "el cheapo" oils fared pretty well compared to the big names.

Thoughts?

You just wrote the "the cheap" oils.

Haven't read it yet, but it looks like an interesting read! That guy got really into detail with a slew of stuff.

I've always prefered to buy whatever API semi-synthetic midrange is on sale in bulk and change every 3k instead of expensive and run it 20k miles. Reason being from what I've seen it's the carbon deposits from fossil fuels and habitual short trips not allowing the motor to get up to to running temp that gunk up and fail your motor, not the oil breaking down.

EDIT: Unfortunately my oil isn't on the list... MANNOL https://mannol.de/en/?action=accesso...ender%2010W-40
Hope I don't prematurely see my rods exit stage left...

I bought a Jaguar XK8 15 years ago and went anal on maintenance including oil analysis. The oil analysis said that full synthetic only reaches full protective capability at 13k miles and should begin to be considered for replacement at around 18k miles.

New cars now internally analyze oil usage and decide on their own when you should change the oil. My Ford Explorer says the oil change light will come on from 6k to 11k but had not come on at 7k. Changed it anyway for a 4k walk about.

Here's a (in my opinion) supplemental Blackstone article put out July 2017 - https://www.blackstone-labs.com/News...uly-1-2017.php

Have fun

All we’re saying is, if you want to try an oil that maybe costs a little
less, you probably don’t need to worry about it causing any problems.
Interesting as this study showed generally great results from the Amsoil Sig Series as well as the original article from 540Rat's blog.

Conversely, Pennz Ultra and Mobil1 scored very well on 540Rat's blog where the M1 did not seem very exceptional in the Blackstone study.

You have to wonder why some of the older engines look terrible inside... Zero oil changes or just cheap oil? IDK but you can tell the difference on a well maintained engine once you pop the valve covers.

From my experience M1 5w-30 or 10w-30 has been great at 10k changes. If going standard dino, Pennzoil 5w-30 has been good 5k changes.

I would say all newer oils with the applicable Starburst rating symbol should be good for general use... So why do we still see engines that are black or dark brown stained on the inside?

I know, not ANOTHER oil thread, but the links contain some very good information in them.

The key here is purchasing the highest rated oil that is 740 price point friendly. Some of the highly rated oils are pricey, some very affordable. Conversely, some of the spendy oils are not that well rated! So buy accordingly.
