As always… nicely done! I would just like to add that reducing oil consumption by using a bypass system has merit beyond the financial point of view. We have a 15L Detroit engine and average 120k miles per year and will us a bypass system to extend the OCI to reduce oil consumption and allow us...

As did I, these guys are brilliant - half baked or fully cooked!

Hey Powerstroke, unfortunately they do not meet the PGOS 93K218 specification or they have not made the approved list in any viscosity. However, they did make the Roadranger PS 164 Rev 7 list under the heading of “other”. If you read backwards on this thread you will see why it is important to...

The Detroit web site is working and for completeness here is the list of approved 5W-40 oils: Amalie, XLO Ultimate Full Synthetic American Agip Co., SYN-GUARD Chevron, Delo® 400 LE Synthetic Citgo, Mystic JT-8 Synthetic Citgo, CITGUARD Syndurance Plus Synthetic ConocoPhilips, Kendall SHP Diesel...

I have a new truck coming in and need to decide what fluids to run in the transmission and rear-end. The following are from the manufacturer’s approved oils list. I am leaning towards the Shell products. Can anyone tell me why I should consider the Mobil products instead? Transmission 1...

This web site has been a great resource for me. I started this thread with the assumption that the CJ-4 specification was the important item when it came to my choice of engine oil and its warranty. This forum caused me to dig deeper into the documentation and I discovered that it is the Detroit...

Why would we forgo the TBN test? is it only needed when you suspect the oil needs to be replaced?

Anyone care to share the name of the lab they use and the things they like about it?

Originally Posted By: salesrep 740,741,742 are manufactured to meet the min. specs for approvals. They do not have our micron moly add pack like the 293,214s,167 and the new 751m. I guess i want to meet the warranty obligations AND have the additive packages that will "Scaefferize" my vehicel...

As I suspected, and to be honest, the fair outcome... I don't know what has transpired to position Schaeffer so poorly in all of this. Are they just cutting costs or is there something else going on. There are plenty of small companies that have made the grade. I do know that it has left me in...

You are missing it a bit … we know the #740-742 meet the specifications but they lack the special additives that make Schaeffer special … … tim

Interesting … Let’s run a scenario so that I understand how this works. The normal OCI for an Eaton Fuller transmission is 100k and 500k for their extended use fluids. I choose to run with the Schaeffer fluid that is recognized by Eaton for 100k but that Schaeffer states will meet the 500k...

Are you saying that products #740-742 are 100% pure Schaeffer products and are blended by Schaeffer but stop short by just meeting the manufacturer’s minimum requirements? And that if I want the additive package that will give me the “Schaefferizing” characteristics I seek that I have to switch...

Thank you, I am a little confused with these products #740-742. Are these oils made from 100% Schaeffer products? And who does the blending? I also noticed that it doesn’t have the other additives that Schaeffer normally adds like those found in #293. If I used the #741 & 742 would I really be...
