Yes, I remember those, too. We were lobbying our EBU engine counterparts to drop in an ISB4.5 to the light pickups instead of an entirely new V8. Corporate never did listen to us or communicate. It was one-way with acquired BU's. Too bad - another fiasco for Cummins.

Mom & Dad had a Fedders window unit. What a brand it was. We have some of the last of the really good Kenmore & Whirlpool appliances. One of the new ones is a Whirlpool washer, assembled in USA, but parts all made in China. Water pump went out after 3 years - using filtered and soft water...

The partnership was forced. I worked at Cummins (generators) at the time. Cummins was all set to launch the V8 automotive diesel with Dodge. Then the Great Recession occurred, Chrysler went bankrupt, and Fiat bought them. Fiat agreed to continue the 6.7L Cummins engine in Ram HD trucks, but...

This article in the link below is a few years dated, but not so old it isn't still useful as directional guidance, IMO. Though they don't specify brands, synthetic oils tested generally allow double OC's, which is what I've always followed. If you're using high quality synthetic oil, you should...

Triple_Se7en - what do you make of Mobil 1 ESP 5W-30? Hard to find here, but the attributes I've seen all look good for small GDI's: high shear stability, stout additives, etc. Shame to have to dump it @ 5k OCI's, but oh, well!

1. Worst case machine elements: valve train, cylinders (HTFS) 2. Major load bearing drivetrain: journal bearings (HTHS) That's why I thought Gokhan's work was phenomenal. Yes, I know it's an estimate, but I'm unaware of any other work that provides these answers.

ZeeOSix, Before my account is deleted, I want to ask aren't PD oil pumps variable flow with engine rpm? The amount of oil flowed is dependent on unit time, with lower speed the unit time is reduced. I've appreciated your fact-based posts with your knowledge and background, not resorting to...

Originally Posted by MolaKule There is no such thing as an oil that does not shear. Some oils shear more than others depending on a number of factors. Gokhan's calculations and charts are theoretical constructs and are to be taken with a grain of salt. Got anything better to go off of?

FCA is a very euro-centric company, and most familiar with Royal Dutch Shell products because of it. It's essentially a Fiat company now. The low vis is for fuel economy standards in both europe and north america. Middle East is a much hotter climate and if there were a temp / vis chart like...

I switched from Mobil 1 to Pennzoil PUP when SOPUS bought out Pennzoil due to superior cleanliness when the need for such started about 5 years ago due to engines starting to use engine oil as a hydraulic oil for VVT and MDS engine systems. Now I am considering changing due to engines changing...

From Gokhan's Chart, the top three shear-stable oils are: 1. Ravenol VMP 5W-30 2. Motul 8100 X-clean+ 5W-30 3. Red Line High-Performance 5W-30 The next level of shear-stable oils are: 4. Pennzoil Platinum Euro 5W-30 5. Mobil 1 ESP Formula 5W-30 6. Amsoil Series 3000 HDD 5W-30

Search for Gokhan's shear stability chart. I don't recall which forum it's archived in.

Wow, that's awesome. Thanks for sharing, Pete.

What's with the personal hostility, dude? I thought this site was for sharing info, opinions, and learning stuff? You tell everyone their experiences are irrelevant? Where's the Moderators?

The chart means my 'opinion' differs? Then why the complaints here from those who bought and complain? False equivalence.

How is my personal experience, along with the experiences of those here with engine issues, "jumping to a conclusion"? How can you tell me that my personal discomfort is not valid? That's very presumptious.
